    Q:My contractor said he applied RedGard one wall at a time and tiled each shower wall separately. Is it appropriate to use RedGard this way?

    A:  In order for us to give you the best possible answer, we would like to know a few more details regarding your project. For further assistance please contact us at 1 800 282 8786 option 2.

      A:  That is not the way we do it.  Red Guard needs multiple coats to achieve a proper water proof layer.  Seams and screw heads are points of potential water penetration.  Tile and mortar are NOT WATERPROOF.  Use mesh tape or red guard fabric to help seal the seams and corners.  The waterproofing on a shower need to bond the floor pan with the shower walls.  We recommend a preformed shower pan that can be tiled.  They can come water proof and sloped to give you confidence in the process. 3GBLLC of Charleston

          A:  Yes according to the manufacturer, It can be used for all interior or exterior commercial, industrial and residential tile and stone installations. however I would recommend keeping or covering the project from rain or water until fully cured & dry.

              Q:How long after applying a red guard can I tie in over
              by|Jan 27, 2023
              2 Answers
              Answer This Question

              A:  Depends on the weather, but  a soon as it turns red between 1 to 12 hours, in my case just took 2 hours to get dry.

              by|Feb 3, 2023

                A:  RedGard Waterproofing and Crack Prevention Membrane can be tiled over as soon as the membrane dries to a solid 'Red' color; typically a minimum of 1.5 hours. For further assistance please contact us at 1 800 282 8786 option 2.

                  why did I waste time and money for this
                  thought this would save me some money and labor by going this route for my tile flooring. Wasted a whole day prep and applied 5 buckets to find it all peeling in so many areas. Disappointed

                        Superb sealing - You get what you pay for!
                        Like Drylock, this stuff goes on heavy, and you want to put on two coats. It is definitely superior to Drylock, however. If you are doing basement walls and floors, like me, remember to brush all the loose dust away first (with a broom). And you'll want to get a brush to fill in wider cracks, and/or deeper divots, that a paint roller just can't get into. Expect that you will lose your paint roller, because this stuff seals up very tacky! Also, the fumes are pretty intense. I recommend doing this when the weather is nice, and you can open up windows.

                          The product itself is very easy to use and after it dries and cures it’s ready to be worked on.

                          Worked perfectly. Applied to the bathroom plywood sub-floor in mobile home. Once product has dried (turns red and there is NO question is dry), we applied self stick tiles. Small gaps filled and there are no air pockets...perfect. We thought the product was too expensive. However, when purchased in the 3.5 gal size, the price was very comparable to most primers/sealers.
