1. Wood Finishes

i. Natural Oils and Waxes

Via Tried and True
Linseed and Tung Oil

Linseed Oil and 100% Tung Oil are the traditional natural finishing oils for wood. Tung oil is cut with a thinner, which is usually hard to tolerate. Linseed comes in three types, raw (which is pure, not usually used for wood as it takes a long time to dry and is often cut with a thinner), "boiled" which has driers, usually metals like colbalt or petroleum, (which I would want to avoid), and polymerised/stand oil which is pure, food safe, and faster to dry. This one does not require a thinner. Polymerised is the type you want to use. The odours of these oils (especially the citrus solvent) comes from their naturally occurring VOCs. For the chemically sensitive, these two oils have odours that are stronger than other options and the solvents/thinners, are not always tolerable (the smell does fade with time). Tung is a stronger smelling oil than polymerised linseed.

Woodworkers having varying opinions on the two oils, each camp preferring one over the other, with some noting caution to linseed as being less mould resistant in certain conditions. And tung having the advantage of holding up well to water and mildew outside.

Rubio Monocoat makes linseed based finishes (natural and modified) that reportedly smell like honey or lemony incense. It contains a wax component (natural and modified) as well. They claim zero-VOCs. You may still want to test that product before using it. The accelerator which is a part B drying agent, lists hexamethylene diisocyanate as an ingredient (0.5%), but not all ingredients are listed. Because part A (without the drier) takes a very long time to dry it sounds like part raw linseed to me. This means part B is unknown driers and hexamethylene diisocyanate. It does contain non-aromatic hydrocarbons but they claim no metalic driers and no solvents. I will only use brands that disclose all their ingredients. Though sensitive folks reporting that they really like this brand is important.

Fusion is a similar oil and stain in one that is more transparent but they don't reveal all the siccatives (driers). Tried and True is my top recommendation for linseed + stain because of their disclosure of ingredients, and no driers are used.

Oils labeled as teak oil or danish oil from hardware stores are usually a mix of oils like linseed or tung, solvents, and possibly resins, UV inhibitors and mildewcides. Make sure they disclose all of the ingredients.

Other Drying Oils 

Milk paint pigments & hemp on floors,
hemp on window frame,
still unsealed cabinets
Hemp Oil is a good alternative oil for wood finishing (indoor use). It does have a light aroma, which I would consider pleasant, but I would test for your own sensitivities (and allergies!) by buying a small amount first (they claim the only ingredient is hemp oil in the Milk Paint and the Homestead House brands).

Linseed, tung, refined hemp and walnut oil are drying oils (although some claim walnut is a semi-drying oil so I would not recommend it over the others. I have seen it turn floors rancid). The drying oils penetrate, harden and preserve wood and provide a long-lasting finish that does not turn rancid. Coconut oil if refined, is another option. Just don't use regular cooking coconut oil. I wouldn't recommend using olive or other (non-drying) oils that can go rancid on wood.

Another oil to check out is Penofin Verde which is Brazilian rosewood oil based with "other natural oils combined with select vegetable ester solvents and zero VOC pigments". It has 1g/l VOC and contains linseed.

I used Hemp Oil on all the interior wood in my chemical-free tiny home (floors, stairs, interior door, window sils). I am really happy with it. The ladder to the loft does get grimy, though the dirt does wipe off. Use refined hemp oil (made for a wood finish) as opposed to the edible oil from the grocery store. This finish is certainly the safest and healthiest option for wooden toys, countertops and other food safe surfaces.

Oils need to be reapplied every few years or more often in high traffic areas.

Waxes

Wood (but not floors) can then be finished with a beeswax polish for extra durability. Beeswax takes 30 days to dry. I used beeswax on the window sills to provide a water-resistant finish and I'm really happy with it, it would also work well on counters, cutting boards and toys. This Beeswax/Carnauba Polish works well but has mineral spirits in it. Mineral spirits to evaporate and leave the product free of this ingredient once cured. Here's a helpful video on finishing wood with food grade hemp and beeswax finish. I like this Fusion brand as well (which is 100% Hemp, and beeswax and hemp with no additives). Wax needs to be re-applied every year.

Shellac is a resin, and one of my top picks for many different purposes. Shellac it it's purest version is the natural flakes and alcohol. You can purchase this from shellac.net or Amazon. Shellac can be used on many indoor surfaces, including floors, toys and furniture. Natural, de-waxed, would be the purest choice for most projects but it does come in synthetic. If you want to buy it ready made, Zinsser makes one they claim is only shellac and alcohol. I discuss this again in the section on sealing in toxins since this finish is great at sealing in offgassing and odours.

Oils for Earthen Floor Finishes

If you don't have ox blood on hand, no problem, you can seal your earthen floor with any of the hardening oils we talked about under wood finishes. I would use Hemp Oil, though a final coat of linseed and possibly wax, may be needed. This blogger claims that Walnut Oil went rancid with time. Beeswax can also be used in the final coat for extra protection if desired.

ii. Stains

Photo from homesteadhouse.ca
Each oil on its own will tint the wood to a varying degree, so you should test for the look you want to achieve - you might find that you don't need a stain at all.

Non-toxic milk paint pigments can be used as a stain applied to the raw wood before finishing with oil and wax. Here is my how-to for these pigments as they are very tricky to work with! I used them on my floors, my bathroom cabinets and my two stairs. I was not very happy with these stains. Earth Pigments also makes natural stains. Be sure to test them first and follow the instructions on the type of wood and how dark you can go, and you will get better results than me. I prefer the oil and stain in one options. Rubio Monocoat, Penefin Verde are two examples.

For non-toxic water-based stains, I  would recommend either ECOS Paints stains or AFM Durotone.

iii. Wood Sealers

ECOS varnishes, which I previously recommended, have had some reported problems. A few people are now reporting that water leaves very bad stains on the wood. This could be a major problem that would cost a lot of money to fix. I used ECOS sealer on the wood in my kitchen and am very happy with it. I have not had these problems so I do not know what accounts for it, but for now I am suggesting caution with ECOs. Though other polyurethane finishes can also have this problem.

AFM Polyureseal is liked by many. Another zero-VOC polyurethane is Vermeister.

An unusual non-toxic way to finish floors is a Danish process using a soap finish. You can either use just soap, or soap and lye. Lye is quite toxic while it's reacting and I don't know how long that takes to dissipate. When used in the making of soap the lye reacts with other components and in the end you just have soap.

2. VOC-Free Paint

There is a myriad of paints claiming to be green or zero-VOC, but most don't list their ingredients, others list the main components, while some only list what has to be disclosed on a SDS.

i. With Mildewcide:

Benjamin Moore makes a number of zero-VOC paints, one of their oldest lines is called Natura. It is high-quality, and comes in great colours but contains a mildewcide (something you should generally avoid). It was intolerable for me while wet, but good when dry. Make sure they are using their zero-VOC pigments with it. If you want something you can go out and buy from a store right now, this might be your best option. Ben Moore stores are all over the US and Canada.

Sherwin Williams Harmony - another easy to find zero-VOC paint with zero-VOC pigments also has a mildewcide. Sherwin Willians ProMar 200 is the most affordable zero-VOC paint I have seen (zero-VOC pigments). You can buy this brand at Lowes.

(Note: other hardware store brands may not carry zero-VOC pigments).

YOLO Colourhouse - very low-VOC base (can be considered 0-VOC), but the tints contain VOCs. Also contains a mildewcide. Hard to know which market this specialty paint is aimed at. Purchase online or at specialty green building stores.

Dunn Edwards - Spartazero is zero-VOC with zero-VOC pigments. You can find this at smaller chain hardward and paint stores.

ii. Here are the top non-toxic acrylic paints - no mildewcide:

Mythic Paint - The paints and primers are zero-VOC. This is now only available in the UK with some use in Asia. The word is they sold the formula to a new company so I will update as this unfolds (I have not been able to track the sale of this formula but a commenter believes American Pride may be similar or the same. I have not been able to verify that). ECOs is the new fan favourite, but Much Smarter Paint claims to have ECOs matched.

AFM Safecoat Zero-VOC Paint - Tintable to thousands of colors. It is zero-VOC with zero-VOC colorants. (Though the primer is low-VOC.) No mildewcides. You can buy this online.

ECOs - Their primer and paints are zero-VOC. They recently removed mildewcides from the formula (2017) however they have the ingredient 1-hydroxy-2-pyridinethione in there which is the precursor to one of the banned mildewcides. This is the most popular paint right now (2018-2019) for chemically sensitive folks. Buy online.

Envirosafe - zero-VOC, zero-VOC pigments. No biocides. Contact them for dealers.

Durasoy - This paint is a little different, it is a zero- VOC acrylic and natural oil paint. No biocides. You can purchase it online.

Costs:

As of 2017 here is the cost comparison for zero VOC paints:

Sherwin Williams Harmony - $55, Sherwin Williams ProMar 200 - $24-30
Benjamin Moore Natura - $57, Benjamin Moore Regal Select  $50, Benjamin Moore ben $40
Dunn-Edwards Spartazero $50
AFM Safecoat - $59 + shipping
ECOS Paints - $52 and up + shipping
Envirosafe - $44 and up + shipping

iii. Exterior Paints

There are very few exterior paints that are zero-VOC, ECOs has an exterior primer and paint, and AFM has an exterior paint.

iv. Natural, Mineral (Non-Acrylic) Paints:

Romabio - The most popular mineral-based paints. Clients seem to really like them.

BioShield - Becoming more popular, Bioshield makes chalk and clay paints that people like.

Milk Paint - I used Milk Paint in my chemical-free house to seal in the dust on the walls. On unfinished wood you need to add white glue to milk paint and I have not found a glue that I found 100% tolerable. Milk paint is also not great in a high moisture area like the bathroom because of the casein. (It could be prone to mould in a high moisture area). I would avoid it if I did things again. Though it's great for some applications.

Green Planet Paints - (Natural Source, Clay-Based Paint) available online, and in specialty paint stores in Canada and the US.

Auro Natural Paints - (Natural Source, Clay-Based Paint) available online, ships to US and Canada.

Clay and milk paint are not appropriate for high moisture areas.


v. Primers

Try AFM Safecoat Low VOC Transitional Primer or their New Wallboard Primer for new drywall (both low-VOC, but they seal in toxins).
ECOs is another brand that makes primers including a new wallboard primer (no mildewcide).
Sherwin Williams Promar 200 is a zero-VOC primer (no mildewcide).

vi. Metal Primers

AFM makes MetalCoat Primer (zero-VOC), the Mythic Primer above can be used on metal (now out of business in North America, but available in the UK).

vii. Cabinets Sealers and Paints 

Clear Finish:
ECOs polyurethane (0 VOC)
AFM Acrylac VOC 124g/l
AFM Poly BP VOC 120 g/l
Vermeister Polyurethane Finish 0 VOC

Painted Finish:
AFM Safecoat Ecolacq

Regular paint with a clear finish doesn't usually look great on cabinets as it will look painted with brush strokes. If you do want to use a conventional paint on cabinets, Fusion makes acrylic paints with mineral tints for furniture that claim 0 VOC. You can buy a sample pack here. They have some tips on how to paint with fewer brush marks and they have a product to help you paint over old cabinets.

Oil finish:
Monocoat oil plus for furniture
Penefin Verde rosewood/linseed 1g/l

3. Plasters

There are clay-based plasters and lime-based plasters. I prefer lime because it is naturally mould resistant. Plasters can be tinted with natural pigments. Here is a detailed post on my experiences using clay plaster and lime wash in my tiny house.

Plaster of Paris can be highly tolerable. The USG brand comes recommended by sensitive folks and can be found at hardware stores like Home Depot.

To learn more, get yourself a copy of The Natural Plaster Book.


4. Sealers

i. Sealing in Toxins  

My exterior
If you are buying new wood-framed windows, the wood will likely have been treated with fungicides. and should be sealed with AFM Safecoat Safe Seal,  AFM Safecoat Transitional Primer, or Zinsser Shellac. This shellac from Zinsser claims that the only ingredients are shellac and alcohol. That's one you can find at Home Depot as well as online.

Safeseal is also used to seal in formaldehyde in wood products. You can also use a homemade shellac which is one of the best sealers to seal in odours and VOCs.

For sealing in fragrance, smoke, terpenes or other VOCs please contact me for a consultation and we will find the best product for your application.

ii. Exterior Wood Sealers

To protect exterior wood against the elements, you could use something a little stronger (as the VOCs will not be within the building envelope) - oils like Rubio Monocoat hybrid, and Penofin Verde. Clear sealers: zero-VOC Cedar-Seal, the same company makes another sealer for other woods. AFM has a new exterior clear sealer EXT.

iii. Tile, Concrete, Stone Sealers

My favourite
Sealers include:
AFM Mexeseal (for marble, limestone, granite, sandstone, slate and concrete)
ECOS sealer/stain for concrete
ECOs sealer for stone/tile/grout
Lithofin (for stone and more)
AFM Safecoat Penetrating Water Stop (zero-VOC) - I am using it on my bathroom tiles and have used it on the clay plaster in my kitchen
Milk Paint Soapstone Sealer for Soapstone
Kinloch is a 0 VOC sealer for granite, marble, concrete and some tiles
Metacreme for natural stones and concrete

Tung oil also makes a good finish for concrete. For a more detailed look at sealing stone and concrete counter tops see my post on kitchens, where I go through the types of counter tops and sealers for each one.

For sealing grout use AFM Safecoat Grout Sealer or AFM Safecoat Safe Seal. I discuss more grout sealers options in my post on grout and thinset.

  3. BioWorx.us is new to the "green" cleaning industry. None of their products contain VOC's (including the glass cleaner and fragrances)or other harsh chemicals. Plus they show on their web site lab studies how BioWorx compares to other cleaning products in soap scum and scale removal. They do quite well in each key cleaning category.

  4. I am really enjoying your blog. My son and I both have MCS, and it is a challenge to find safe materials to renovate with. We are in the process of choosing flooring for our kitchen. We're considering solid wood, prefinished flooring--but are a little concerned about offgassing from the finishes. We're also considering on-site finishing, but I'm concerned about that too! Do high quality prefinished solid wood floors offgas much?

    1. what are they finished with? you will have to test them. polyurathane i have found can offgass quickly as long as it's not in the same building as you when curing. tiles would be preferable in the kitchen I think, or polished concrete.

  17. Hi there! I have had a bunch of drywall done in my house. Everyone I speak to says "oh the drywall isn't an issue for VOC's" but I know they're wrong. I am in Canada, and am looking at a product that is Greenguard certified, less than 45 g/l VOC and is a Drywall sealant/primer. Do you think this is OK for sealing in VOC's from drywall before I paint?
    I just can't find ANYTHING in Canada that is labelled for "sealing" drywall so it's all just primer/sealer, or just primer. Any advice would be so appreciated! Thank you so much!

    ReplyDelete
    Replies
    1. Depends on the drywall. Which kind did you use? 45g/l is not that low. But there is no drywall sealer that is zero VOC. Just primer will seal some VOCs though.

      Delete
    2. What about Ecos passivating primer?

    3. It has a mildewcide and I have heard it doesn't seal in odours well.

    4. I know this product doesn't belong on this blog, but I found that the original oil-based Kilz primer works very well to cover odors. But only if you can wait several months for it to completely outgas. I have chemical sensitivities, and after outgassing, it does not bother me and completely took care of the odor from old drywall in a closet. I used the water-based Kilz in another closet, and that never outgased. I had to replace the drywall.

  18. Darn. We don't know..we have contractors coming in and doing it for us with the machines to clean the air and such. To be honest, I didn't realize there were different kinds of drywall...so that is my bad with everything going on in the house.
    45 is the lowest I could find! It was that or "<200 g/l" for drywall sealant/primer. Or a no VOC primer/sealer but it doesn't say specifically for drywall, so maybe that would be the best since it's no voc and it at least says sealer?

    ReplyDelete
    Replies
    1. Which one is the zero VOC sealer? It does need to be drywall primer.

      Delete
  19. It is from Dulux paints, it's called Lifemaster Primer/Sealer. Okay good to know it has to be specifically for drywall. Is 45 g/l awful if that's the only one I can find? Also I just looked at different types of drywall (yay google..) and I believe it was just square edge standard drywall, in ceiling and walls, with putty over top.

    ReplyDelete
    Replies
    1. That is for drywall and it is zero-VOC. However the sealer label means it seals new drywall and is no more a VOC sealer than any other primer. As for drywall VOC levels, it depends on the brand. You can try and look it up by what brand you bought and then compare that to the 45g/l.

      Delete
  20. Okay so you mean that a "sealer" doesn't seal VOC's any more than a primer would seal in VOC's. So basically I want to find a super low VOC New Drywall Primer, and hope it helps..
    Drywall has specific amounts of VOC's depending on the brand...okay yes this makes sense, never thought of it. This whole chemical sensitivity thing is quite frustrating I have to say :(
    I'm sorry, I don't quite understand what you mean by comparing the drywall brand to the 45g/l drywall primer!

    ReplyDelete
    Replies
    1. Yes exactly.
      I would see the VOC level of the drywall if you can find it and see if it's worth adding 45g/l in order to reduce the drywall offgassing.

      Delete
    2. Okay makes sense for the primer vs sealer. If i was in the states I would get either the ECOS or Afm safe coat and this would be easier.
      Okay great, will do! If I can find it, and it is low, would I be best to just use a zero VOC primer like the Lifemaster (i believe that was a drywall one), to reduce any VOC's leeching out?
      Also thank you SO MUCH for all of your help, I apologize for being such a newbie.

    I bought an antique table and wanna take no chance concerning possible moulds: if ever there were moulds in between 2 wood planks, would a wax (applied on top of floor hemp oil) be sufficient to seal any possible neurotoxin/spore/mould in? thx much in advance.

    ReplyDelete
    Replies
    1. Mould in between 2 planks? That would be an unusual place for mould to grow. Are you talking about the subfloor and the wood flooring? A beeswax no, would not block spores. Sounds like you want your wood to breath. The only kind of wax that I know of that is relatively impermeable is shellac. This is not used on floors though.

      Delete
    2. Hi Corinne,
      thank you very much for answering.
      It's for an antique wood table top: 2 planks had a gap and were not sealed and the table was used in an orphanage for many years. So i worry that some liquid might have spilled repeatedly in the past in between these 2 planks and that maybe molds could have developed there. As it could ruin the table top if I took these 2 planks apart, I would like to properly seal the complete table top and if ever there would be spores in there, be positive that they could not escape from the sealed table top into the air. Do you think carnauba wax (maybe mixed with candelilla wax) could be enough to accomplish that?
      thank you very much for sharing your knowledge and experience.

    2. Consult a building science expert on this. Normally you do not seal this on the inside. The source of the water getting in needs to be fixed.

  27. I happened upon your site while looking for a low VOC sealant to use on our vinyl kitchen flooring. It is about 21 years old and we don't want to replace it till we sell our home next year. I cleaned it with baking soda and it really did a great job, but my husband says we need to seal it. Do you have any suggestions please? Thank you for any advice you can provide. I am so happy I found your site.

  29. Hi, the governement house/department of housing house (in Australia) that we live in has just been painted. As a result, we don't know what type of paint was used yet suspect it was a very cheap one. It seems as though the new paint is making me very sick and I'm wondering if you can please recommend a product that can be purchased in or shipped to Australia (maybe some type of sealant or something else), that could be painted over the new paint to seal in the VOC's/off-gasing from the new paint? Do you think this method will be sufficient to seal in all or enough of the VOC's in order to prevent me from feeling ill? Thank you, emma

    1. Hi Emma, sealing in new paint is tricky. There are a few options you can try to help reduce the offgassing. I would need to look into what is available in Australia. This would be done as a consult. Please check out my page on consulting. It is 25 USD per half hour. This will take an hour of research and email. Thanks, Corinne corinnesegura@gmail.com

  30. Hi, Thank you for sharing all this great info! I'm helping renovate a friends house, and she is very chemically sensitive, so your advice and product listings has been great.
    In one area there has been rats under the tub, and the subfloor is still smelly from them living there, despite bleach cleaning etc. What waterproof sealant would you recommend to both protect from water splashing in the future, and to seal in smell? Conventional solutions would be RedGuard or Bituthene. Do you know of a low VOC, more natural alternative? We're in a mold-prone area on the west coast. Thank you!

  40. I am a painter. Also have chemical sensitivities, so I know a little about toxic products. I would be wary on basing too much on Zero Voc products as that does not mean Zero Toxic. Voc's only mean those chemicals that react to sunlight to create smog/ozone. So the regulations were written with human health Not in mind. There are many exempt chemicals that are very unhealthy to you and me but perfectly fine against the ozone, so they are Zero Voc. "Low odor" products is probably more important than Zero Voc's, but at the end of the day the product needs to be used to see how toxic it really is.
    I have had lots of problems with Sherwin's Promar 200 Zero Voc. They do not have a zero voc colorant system so depending on the color it will have more odor. I do not recommend Sherwin. Benjamin Moore has a zero voc, low odor colorant system. Their Ben line I believe is the healthiest, great paint, just need to add some water so it brushes like butter. Next healthiest of their's is Natura. I don't use Regal as it has some more odor. Their expensive Aura is an example of having Zero Voc's, but it definitely has a toxic odor.
    Though it is not extreme like BIN Shellac. I don't know how that got on this list. As it is known to be extremely toxic to people.
    http://www.earthpaint.net is something to probably list on your site, as they seem to have some of the best and more well known wood finishes. They also have a paint. And a natural mold killing lime primer.

    1. Hi Sherwin Williams does have zero VOC colourants. Zero VOC is definitely the best place to start. Going by the ingredients list or even AFMs GAPs does not necessarily lead to to figure out which paint is better for them. How offensive the odour is to you is definitely a good guide I agree. For those really sensitive they will need to know how long it will take for them to not react. Most people have different brand preferences it's not simply how toxic it objectively is. Bin shellac is one of the best sealers for blocking smells but it is hard to tolerate. I recommend pure shellac.

      Delete
    2. I spoke with Sherwin Williams twice in 2018, and they confirmed that ONLY their white paint is VOC-free - As soon as they put in dyes to make a color, it will become a VOC paint again. Then, each color you choose will have a different level of VOCs. So, really, Sherwin Williams' labeling is misleading since it only applies to white, before choosing a color.

  41. Same painter here. Also wanted to share http://www.ecosafetyproducts.com, which has interesting soy paint. And I know the Colorhouse is a pretty decent paint. It is actually made by Dunn Edwards, which you have listed as well. I have a big hunch that it is just relabeled that same zero voc product from Dunn Edwards.
    And I used Mythic a lot, it worked pretty nice. They had a great primer. Just so you know, that same paint might still be getting made. When it was originally created, before called Mythic, it was called American Pride. Was actually created to paint the Pentagon after 9/11, which you may already know. So Mythic went out of business a couple years ago as you know, but I had noticed that American Pride has been getting sold at some stores, so I believe it is being made still. It is the same paint as Mythic. Here is their site, not a lot of info but does have stores on where it could be found: http://www.americanpridepaint.com/
    A couple more paints you might be interested in: California Paints, they have a zero voc colorant system like Benjamin Moore that won't had toxins with colors like Sherwin will. They have a zero voc offering, but few and far between on tracking down a store.
    Also, I heard PPG has a zero voc colorant system. They have Pure Performance paint that has been well known by painters as a healthy offering. Just thought I'd share what I know. I learned about some good ones I didn't know from your site, I appreciate that. Regards, J

      I had a problem with one store that sells Benny Moore, with their zero Voc Gennez colorant system, but the store also sold other companies and had universal tints. I was buying Ben Moore paints thinking they were the best, but still having surprising problems with odors. I came to find out the store was not using Benny's Gennex colorants but basic universal tints which added incredible odor. As soon as I switched stores it solved that issue.
      I learned a lesson for myself that odor does not completely depend on the paint brand, the store which mixes it with their colorant plays its part.

    3. I have had that experience with stores as well. AFM paint is the least well-tolerated amongst my clients and people on the Facebook forms for chemical sensitivities. In my experience the best tolerated paints are Mythic and ecos.

  45. Also you might be interested in clear top coats I found. The Lumber Seal company also makes a Furniture Seal which sounds like a durable poly.
    The gentleman from Earthpaint.net said their Easy Finish is the best replacement for polyurethane's. Second best is their Nanotech. They are both more than durable and rated for floors. Their Nanotech can also be tinted to make it a stain and finish. Their Bio Naturals, which has a pine resin, which also can be tinted. That one has a slow dry time so I'm not too interested. Their have a Mountain finish which is made from cashews, but can only be applied with light coats with a rag.
    That www.ecosafetyproducts.com has nice sounding finishes rated for floors. One is made from soy, a couple others that look healthier than standard polys. They also have stains made with soy, those sound nice, fast drying.
    The 3 company's for clear topcoats above I have not used yet, but I have used one that I love from Vermont Naturals.It's partially made from whey,
    leftover from cheese making, adds durability. Their Furniture Polywhey has a decent amount of odor and fast drying(harder to hide brush strokes), I don't recommend too much unless you want more durability. But they have a Heirloom Finish that is great, very low odor and levels extremely well. Not sure if I would put it on top of a table, probably doesn't have that durability. They also have Stain and Finish, which is like Polyshades, but it's a much better product. I would put the clear coat Heirloom over the Stain and Finish. Both of those have low odor. www.vermontnaturalcoatings.com

    Sherwin has been telling me for years that they have a zero voc colorant system but I've had some bad experiences with them sometimes, with strong odors in certain colors. I would like to give them another try and see how Harmony is. I've been so really pleased with Ben from Benny Moore that I haven't bothered trying anyone else for walls in a while. Alright, I've blabbered enough.

  46. Yes, I used AFM to test it out. Brushed very nicely, like a regular paint. Though the semi-gloss was too shiny for my taste on trim. They have a softer sheen pearl that I would use on trim. I know a painted who sells and paints with AFM and he really believes in it. If I had to guess, I would say out of the regular paints, they are one of the safest ones out there. I never used the natural oils paint from AFM, so I have no idea on that.
    One thing I did not like about Mythic/ American Pride was that after storing the paint for awhile it could grow bacteria or mold that made it stink like rotten eggs. I guess that is because of no mildewcides and such. I imagine storing those kinds of paints with the paint cans upside down so more air tight would prevent that.
    I've been searching lately for more healthier options for tannin sealers. I'm really against the original BIN, even though I know it's the standard.
    For professional paints, from the same company from BIN, Zinsser, they have "Advanced BIN", a synthetic shellac for stains. I used it successfully on a couple oak cabinet jobs. It has great adhesion and much lower odor than regular BIN. Some say it's hit or miss on blocking stains. There is also Zinsser "Smart Prime"/ "123 Plus" (the same product with different names) that blocks tannin stains well. Another is Kilz Max, some really like it's sanding and tannin blocking. And a new one from them is Kilz Max Clear (not Kilz Clear), which is a clear sealer and listed as low odor and able to block tannins. I really want to try that one. The other 3 have odors of regular latex paint.
    For safer sealers I found cool soya sealer from Canada.
    https://soyaoilcoatings.com/wood-knot-and-resin-blocker-primer-sealer/
    In the States there is another soya sealer I found, more geared to the faux finish market. I am not sure if it could accept stain afterwards like a clear shellac. She said it dries cloudy like an oil varnish. It can be used as a topcoat also, and is exterior grade so suppose to be decently durable. Safe to use inside also.
    http://artisanenhancements.com/wp-content/uploads/2017/10/Clear-Topcoat-Sealer_SEALER-GUIDE_SealerComparison.pdf
    I found another sealer that can be used to seal in tannins, called Lumber Seal. Used on bare wood and acrylic paints. So may possibly be used similar to a clear shellac, but not positive how well it could take stains.

    1. That is pretty surprising about AFM. They were supposed to be the earliest of the health minded paints, you would think they would of mastered a safer formula by now.
      I wonder how Clear Skies from Earthpaint.net would fair with people with chemical sensitivities. It's not zero voc, but zero voc is only regulated for smog/ ozone and not the end all/ be all for healthy paints.
      It would be interesting if American Pride (Mythic) comes back. I had heard Mythic was bought by a German paint company. I figured to relabel into their own. Mythic was pretty popular in the UK.
      I had searched and found the Colorhouse equivalent in Dunn Edwards paint. Colorhouse was based off of Everest from Dunn Edwards. Here's the two product data sheets from each company. They are both 100% acrylic, same finish(sheen), same volume solids, the weight solids off a bit, but everything else is the exact same including dry time and coverage.
      Just thought it was interesting. Dunn Edwards probably updated the formula for their Everest, while not bothering to update the Colorhouse because even though the product data sheets are the same, the msds is different. On HMIS codes, Health is listed as 0 for Everest and 1 for Colorhouse. It's a health scale of 0-4, with 0 being the healthiest. So however Dunn Edwards makes the two, they make their own Everest line a little healthier.
      Here's the data sheets:
      https://de-production-media.s3.amazonaws.com/uploads/product_information_sheets/EVER10/EN-EVER10-PDS.PDF

      http://uploads.colorhousepaint.com/2014/09/25171947/Colorhouse-All-Sheen-PDS_Inspired_rev1.10.17w.pdf

      And the Colorhouse Primer is the exact same as Ultra Grip Select(find it w google). It's funny to me because Colorhouse acts like a new age hippie company run by a couple of moms who make the paint in their kitchen. It's all in my opinion but the data sheets tell all.

  48. Thanks Jim! How does ecos compare in this realm of healthiest paint?

    ReplyDelete
  49. You're welcome. I haven't used Ecos. They charge quite a bit, so I hope they would be good to go with their formula. Corinne has good success with it so worth a try.
    A lot of these paints need to be individually tried out just to see what effects they can have on you. Only so much one can gather from reading the msds or product data sheet on these paints, kinda like reading the tea leaves. Paint companies are able to hide so much from their customers. I have read that paint companies themselves were the ones who originally wrote the regulations for Voc's. Instead of having the government make regulations on making safer paints to people, they wrote the regulation of Voc's to be only to the chemicals that react with sunlight to create smog and effect the ozone. So some toxins can be not so healthy for us, but perfectly fine for the environment, so they are exempt. Ammonia and Acetone are exempt. Sherwin and Behr have a lot of ammonia, probably not Harmony, but I know "zero voc" promar does.
    Ecos is worth a try. I didn't smell too much from AFM and I have some chemical sensitivities but not as much as others, so they might be worth a try. That Dunn Edwards Spartazero is worth a try. Their msds is extremely clean, but for some reason they don't list titanium dioxide like other companies do, as it is carcinogen(who knows how bad). Any acrylic paints like all these have to have titanium dioxide. Unless they are the mineral paints like Romabio, or a natural paint like Milk Paint.
    That Clear Skies from Earthpaint might be worth a try. There is also a bio based soy paint called Durasoy that claims to be non-toxic. And Also Ivy Coatings that claims to be as well. There are not many user reviews on these, I have never used, but they claim to be safer. Just some options for you. I'm pretty happy with Ben from Benjamin Moore, has a slight odor but it's fine for me. It's local which is easier for pickup.

    4. I have no experience with them, but AFM has Hardseal that is meant to seal in off gassing. And another for mdf called Safeseal.
      Now they both look like they might have a little odor themselves and I don't know how effective. Ecos Paints looks like they have some "passivating" primers/ paint that seems to try and accomplish the same. I don't think theirs comes in a clear, at least I couldn't find one. They do have a clear in an "air purifying varnish" that supposedly removes toxins in the air. Do not know if those work as intended as well.
      I don't know if there are any other brands out there that try to do the same. I would call each company and try to talk to a tech to find out just how much odor they have(don't want to add too much more odor when you are trying to get rid of it) and how effective they really are. Could look for reviews online to see what others say about them, if they work properly.

    1. Depends if you are sensitive to wood. You don't have to finish it but putting a sealer on will protect it. Most people can tolerate the natural low odour oils like hemp or the coconut one mentioned. Those won't block the smell of the wood though. Shellac will block some smell and is well tolerated.

We were given three options by our painter, Behr's Premium Plus Zero, Sherman Williams Promar 200 and Dunn-Edwards Spartazero. Based on the information here, we're debating between Promar and Spartazero. All 3 paints are listed under "with mildewcide" but then Promar is listed under Primers with "no mildecide." Can you clarify? Are they two different products (paint vs. primer) with the same name, one with mildewcide and one without? If Promar has no mildewcide, we'll go with them but if they all do, then maybe we'll try Spartazero thanks to Jim's comments about how they're worth a try and their msds is extremely clean.

  58. Hello Corinne,
    Thank you so much for you reply... yes, I meant the interior walls and ceiling. Since you are an expert, what would be YOUR best recommendation in terms of a CLEAR sealer to be applied over this probably oil-based polyurethane varnish (quite thick also)? Of course, we would try with a sample first... I looked onto the AFM SafeCoat Polyureseal BP and the AFM Safecoat Safe Seal products, and they mention the following: "Do not use over oil-based polyurethanes or oil-based products as it may not adhere properly."... Oh no!... So, what else can we do? We really can't sand all that surface and refinish it with hemp oil or another natural sealer, it would cost us a fortune!!! Plus, we don't even know if the owner would allow that... And what about varnishing on top of the old varnish with ECOS WoodShield? They claim zero VOC and no odour... Could it actually seal off the old varnish? We were told by the owner that the current varnish is really old... more than 10 years, supposedly... yet, it still smells (and feels :-( ) so strong! Unbelievable, no? Even my husband (who is not MCS) smelled it (but it didn't affect him)... Oh boy... If only people would use eco friendly products, if only... Thank you dearly for your precious help and time, and looking forward to your answer...

    1. No, that likely won't be enough of a seal. It depends how sensitive you are. Another coat of paint and primer will only help a little. I would see how strong it smells first to see if you should even try and seal that. You will need to test that paints and waxes that seal to make sure they are not worse for you and also know if it can take a interior vapour barrier.

We haven’t had any “official diagnosis” of chemical sensitivity but my oldest and I definitely are more bothered by odors etc. We have 3 children and they and I have allergies and 2 of us am immune system that isn’t as robust as the rest so our goal is the build the healthiest home we can within our budget. We’ve been told AFM is the best for sealing out vocs etc and I was even going to have the cabinet guy paint cabinets in the ecolaq from afm. Please advise. Thank you!!!

  64. Hi Corinne. Great blog post. We have an unfinished solid wood closet made by Lundia. We also have 2 sheets of formaldehyde free poplar being used to build on to the closet/wall area. Would using hemp oil first, then finishing with a beeswax finish be sufficient to seal these? Would these applications make them more mould resistant?

    1. Not sure what you mean by formaldehyde free poplar. Hemp oil would need a good amount of time to dry before putting clothes on it. I would not use beeswax in that application. Your closed should not need to be mould proofed. If you live somewhere tropical where you humidity is inevitably really high then you would want to use a rot proof wood.

  65. Hi Corrine, I am hoping you can please give me some advice! About 2.5 years ago, we had a new window and 2 large sliding glass door units installed. This was retrofit, not new construction. This took place during the summer. The odor was very minimal. HOWEVER, the following summer and this previous one, in only one room with one of the new sliding door units, the smell became unbearable. The smell was very noticeable during the late afternoon when the afternoon sun is beating down on the unit. It is a very chemical like smell. I am 99.99% sure it is the caulking used...when I smell under the wood molding where the carpet and sliding door meet, I smell that odor. I am thinking I should cover up this caulking to seal it up. In one of your above posts, you suggest a shellac. What do you think? Which product would you advise to paint over the caulk to seal in the odor? Thank you in advance!!!

    1. That is a little complex. I would want to know why it did not offgas the first summer. I would want to test all products before use and know what is in there so you know exactly what it is and how it is getting through. I would want to be sure it is not the window material itself. Once you know where it is and how it is coming through you can look to ways to seal this. But you have to also be careful here that you are not trapping moisture.

    2. THANK you so much for your response! Your questions are good. I don't know why it didn't smell that first summer. We are really at a loss of what to do other that replacing the entire door. Thanks again.

  66. Afm or ecos paints and primers which one do you prefer? We are removing our popcorn ceilings and need to prime and paint them. Benjamin moore and sherwin are definitely easier for me to buy but I dont want mildewcides. Thanks

    1. I prefer ECOs which does have a preservative that is somewhat of a mildewcide. It's still people's top choice.

  67. BioShield Clay Paint Caution - Although it had zero odor while applying, it had an odor afterward. It still smells, and I have a burning sensation in my eyes and throat 4 months later. I painted in December and have been unable to open windows to get good ventilation. I am hoping with warmer weather that I can "bake" it to reduce the odor.

  68. Looking for recommendations on sealing a desk. Doesn't need to be fancy or even very smooth. Really wanting to seal in odors somewhat, and make sure that hard objects won't stick to it so no paint. My wife is sensitive enough that any kind of bare wood makes her react. Does shellac off-gas quickly? I can leave it in my shop for a few weeks.

    1. Shellac is usually the way to go for sealing in odours. Making your own is the safest.

  69. I'm also suspicious of Rubio. Plus, you're limited to using their cleaner, which contains d-limonene and possibly (depending on your MSDS source) citronella and geraniol.

    1. Oh gosh, no I can't tolearate d limonene or citorneall. I don't think you have to use that. I am still digging into them more and testing it. I will look into an alternate cleaner. This is more or less a linseed product.
