Sealing Toxic Particleboard Furniture

Question from P. N.

I have a crazy situation. I put a $500.00 deposit down on some furniture I love, but found out it's wood veneer over fiber-board. I've been agonizing for a week whether to have it delivered or if I should lose my deposit, or at least some of it. My chiropractor muscle-tested me weak on formaldahyde, so it wouldn't be a great thing, but it was on sale for a really good price, it looks great, it's what I need, but I don't want to get sick and I don't want to feel hypocritical. 

I found this stuff called Safe Coat which is supposed to stop most of the out-gassing but my friend says it will just slow it. Do you have any advice? 

Debra's Answer

About your furniture, I've used the product you mentioned. The exact product is called Safecoat Safe Seal, which is specifically designed to block formaldehyde emissions from particleboard. Not all Safecoat brand products have this ability, so be sure to get this specific product.

My experience using this product was similar to yours. Many years ago, I purchased an inexpensive dining table to use for a desk that I thought was all solid wood. When I got it home and started putting it together, I found that one essential piece on the underside was particleboard. I really needed a desk and this was the only wood table I had found that I could afford. But the smell of formaldehyde was clearly present.

So I got some Safecoat Safe Seal and completely sealed that one piece of particleboard. There was no more odor of formaldehyde and I was able to work at that desk with no reaction.

Your friend is partially right. My best recommendation is to use solid wood. The sealant will block enough formaldehyde fumes to form an effective barrier, but the particleboard beneath it will continue to outgas behind the barrier of the sealant. Over time, it may need to be reapplied. Multiple coats would give you a more complete seal. I think I applied two or three coats it was twenty years ago!.

Now, about whether you should follow through with the purchase for the reasons you stated...Even if it looks great, it's what you need and you would lose your deposit, I wouldn't go through with such a purchase if I knew it would harm my health. If it does affect your health, it will cost much more than your deposit to recover your health, and you will need to get rid of it anyway.

I once had a situation where I was working in a doctor's office who treated patients who were chemically sensitive. He moved into a new office and needed to put down new flooring. I chose a flooring for him that was nontoxic, but his wife, who had an eye for decorating, wanted a different floor--one she chose for style, not safety. Well, being a good husband, he followed his wife's advice and installed 2000 square feet of vinyl flooring. The following week he had to rip it out and install the flooring I recommended because none of his patients could come in the office! So it's better to do it right the first time.
