Hi. I am putting new flooring (Trafficmaster Allure) into my bathroom. I’ve laid down 1/4″ thk lauan underlayment (using ring shanks) before putting the flooring on top. Is it wise to paint the underlayment with Thompson’s waterproof sealer, since this is a bathroom with a tub, toilet, and sink?
I’m concerned that using the sealer will warp/ bubble the underlayment perhaps and not stay flat.
The Allure flooring is a floating type of floor where the pieces are planks 6″ x 36″ with an upward facing adhesive tab on two sides of it. They stick one to the next. The adhesive faces upwards and doesn’t stick to the floor. It is supposed to be waterproof. In the end, after you’ve attached one plank to the next, you end up with essentially a floating floor.
My other concern is that if I have to remove this floor for some reason later, like it isn’t any good or the adhesive tabs are not sticking or whatever, then the waterproofing might interfere with an adhesively applied floor later or even with those self stick tiles I might use down the line. Am I thinking this way too much?
