Question from Laura
The deck of the house where I live is going to be sealed with Thompson’s. I requested a non toxic sealant to be used, but my parents refused – they will use what they have on hand.
My bedroom, the stairway and kitchen are all on this side of the house. How long will it take to cure or will it continually outgas? It had been done last a few years ago shortly before I arrived and I seem to remember conpletely avoiding the deck, closing the door to the deck, closing my bedroom windows, especially in the morning sun.
Debra’s Answer
How long it takes for anything to outgas depends on the original toxicity of the material and the conditions. The hotter the temperature, the faster it will outgas. Also, being outdoors, the sun and other elements will aid the outgassing.
Thompson’s is particularly toxic and will continue to outgass for quite a while. This is could be a significant exposure to toxic chemicals for you.
