Seeking options for no-VOC or less toxic coatings over pressure-treated plywood for an outdoor deck.

Asked by Marcia

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!

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.
