Finish TradesCâu 229 / 700
A shower receptor will use a liquid-applied waterproofing membrane over the tile backer. The MOST important installer control for a reliable waterproof layer is to:
a.Apply a single thin coat as fast as possible
b.Skip the corners since tile covers them
c.Achieve the manufacturer's required wet/dry film thickness and full continuous coverage, especially at corners and the curb
d.Use the membrane only on the floor, not the walls
Giải thích
