Does Thinset stick to RedGard?
Premixed thinset mortar does not adhere well to RedGard waterproofing membrane. In order to make sure your tile bonds well to a surface that has been waterproofed with RedGard, use a powdered mortar. You will need to mix this mortar with water yourself, but it will ensure a strong bond between the tile and the wall.

Combined dried coatings must be at least 30-35 mils thick. When wet, the combined coatings must be at least 60-70 mils and must not exceed 125 mils wet-film thickness. RedGard® is dry when it turns solid red, with no visible pink color.
How long should RedGard dry before tiling?
1-1/2 to 2 hours
The product is dry when it turns solid red with no pink showing, normally 1-1/2 to 2 hours. Depending on ambient conditions, drying time can take up to 12 hours. A water test can be conducted 72 hours after application if required. Clean tools and hands with water before material dries.
Should I use RedGard on Hardibacker?
No, you do not need to apply Redgard over your Hardibacker. Here’s why: Redgard works best on cement boards and plywood because it prevents water from seeping into those surfaces.

Do you have to seal cement board in a tile shower?
Although most backerboards currently available won’t fall apart when exposed to moisture and are somewhat water-resistant, they aren’t waterproof. To prevent moisture from seeping through to the wood or metal studs beneath the tile, a barrier or sealant must be used on porous materials.
Do I need to thinset before RedGard?
