RedGard is a liquid waterproofing membrane used to seal a shower pan before installing tile or stone. It is used in residential and commercial settings and is easily applied. It meets Uniform Plumbing Code specifications for waterproofing and is environmentally friendly. In order to avoid leaking from the shower, and possible mould and mildew contamination, follow these steps to ensure the RedGard is applied correctly.
Preparing the Surface
The shower pan must be installed with the proper slope for adequate drainage. Before applying RedGard, the surface must be clean and dry. Any dirt or debris left on the surface could interfere with a sufficient seal and render the application useless.
Once your shower pan is clean and ready, you may begin applying RedGard, which is the thickness of pudding and bright pink. Scoop it out and begin spreading evenly with a paint brush, trowel or roller. Coat the entire surface thoroughly, making sure to get all angles and corners. When the surface turns red, it's dry. This is typically within 1.5 to 2 hours, but it could be longer. Before adding a second coat, inspect the surface to make sure all areas have been filled or covered. If doing touch-up, make sure all areas are completely dry before adding another coat. A second coat is always necessary. A third coat can be added for extra protection and ease of mind.
There are some limitations to applications of RedGard. If the temperature of your surface may drop below 4.44 degrees Celsius within three days of application, do not use the product. Don't ever apply on wet surface. RedGard should never be used as an adhesive or left as a final surface. It must always be covered with tile or other permanent flooring. In the time between application and tiling, make sure the surface is not dirtied or punctured.
