Hi,

I a getting ready to install Marmoleum Click 1x3 plank flooring in a 19 sf powder room. Only a 3/8" subfloor exists. The Click has a 1 mm cork backing. I was advised the subfloor thickness was sufficient but am a little concerned as to whether it is accurate. Also, there is some give with the subfloor. Any help would be appreciated. Thank you!
