Question from Cindy
We are having a new subfloor installed under our new bathroom flooring, which is Armstrong cushionstep. What is the best subflooring material to use that will avoid as much outgassing as is possible?
Debra’s Answer
You can use exterior plywood for your subfloor under vinyl.
I’m more concerned that you are laying a sheet vinyl no-wax floor on top. Please reconsider your flooring. Ceramic tile would be the safest and it’s very inexpensive at places like Home Depot and Lowe’s, and use a cementboard subfloor.
