A ready-to-use elastomeric waterproofing membrane for both commercial and residential tile and stone application. Suited for interior and exterior substrates, RedGard® creates a continuous waterproof membrane barrier with outstanding adhesion and reduces crack transmission in tile and stone floors. It bonds directly to clean metal drains, PVC, stainless steel and ABS drain assemblies and can be used as a slab-on-grade moisture vapor barrier under all types of floor coverings.
Any time you are building a shower pan you need to do a water test, this is after the pan and curb are in plug the drain, put water mark level and wait 24 hrs to make sure there are no leaks. In the RedGard application this water test would be just before tiling.
Always read and follow manufacturer installation instructions, In order to ensure that RedGard fully penetrates into a gypsum underlayment, we recommend diluting the first coat with water (4 parts water to 1 part RedGard); it works in more effectively on its first coat diluted. Once the first coat has dried, a second coating of undiluted RedGard is required. Full manufacturer installation and warranty available.
