APPLYING TILE Once the waterproofing mem- brane has dried to the touch, ceramic tile, stone or brick may be installed with thinset. Allow the waterproofing mem- brane to cure for two hours at
70°F ( 21°C) and 50-percent relative humidity before covering with concrete, thick bed mortar, etc. Note: Do not use solvent-based adhesives directly on the mem- brane, as it will dissolve the coating.
IN THE SHOWER In the future, whenever you remodel a shower, make sure to take a few extra steps to water- proof your shower. If you use a paint-on system, you can do 100 sq. ft. yourself for $150 worth of materials and two hours of your time. If you’re paying a contractor, expect to pay $150 plus a minimum of four hours of their time to pur- chase the materials, coordination into the project schedule, labor expense, overhead and profit.

Complete the field of the wall. Hydro Ban is a two-coat product, and the second can be applied after the first is completely dry.
After the waterproofing is completed, the shower is ready for tile installation. EHT
