when my family takes baths the water splashes over sometimes. well the floor is lunnolium and the water just soakes through to the concret on the bottom. i live in an apartment comp and there are two layers of lunnolium floor. still the water goes strait to the bottom concreat and the walls soake up the rest of the water. i know i have to take the two layers of floor up, but what else sould i do? i wanted to put peel and stick tile down. is there a way i can seal the floor at the end of my project?
