Question
Seeking options for no-VOC or less toxic coatings over pressure-treated plywood for an outdoor deck.
Contractor wants primer of 210epoxy, then UPC571 coats, then urethane top coat. He says all of these coats will outgas for at least a week, and are very toxic. I am very chemically sensitive and want a green alternative. Help!
Answer
Your first problem is that you have pressure-treated lumber, which generally contains toxic heavy metals that can leach into the earth and get on your skin.
I suggest you:
- first, switch base materials, then
- use a nontoxic sealer and finish from Vermont Natural Coatings or SafeCoat from AFM.
