Installing shower pan. How do I measure a mortar layer thickness?
When I set an acrylic shower base, I mix setting compound and rough lay it based on the base contours. I place a 4mil plastic over the top completely covering the compound. I place the base down over it and press it into position. Once it's set, I lift it up and look at the impression in the plastic. If there are no gaps, I put it back and let it dry. If there are gaps ,I repeat the procedure until I'm happy.
The excess will squeeze out if you haven't overloaded the floor.
