    Q:Can this be used to put on the edge of a tub that has been cut out. If not what type of tubing should be used. Don't want a cut down kit.

    Answer This Question

    A:  Rene; are you referring to a "drop in " tub? where the edge of the tub rests on the tile? If that is a yes, then InstaTrim will work very well to trim your tub provided you follow the cleaning instructions. InstaTrim will not stick to any old silicone caulk. Greg

        Q:Can the peel and stick caulking be painted on? I want to use it in the kitchen but also want to paint on it.

        Answer This Question

        A:  Yes, it is paintable. Be prepared to glue it to the wall, just go ahead and put the glue on before you put it up. Ours came down in spite of proper prep and I had to glue the whole thing, which was fine, just should have done that initially. Other than that I like it.

          A:  Hi, Yes InstaTrim can be painted. We recommend latex based paints for the best resutls. Regards, InstaTrim Products.

            Waste of my time and money
            This stuff does not keep its form no matter what. Shrinks, moves and doesn’t stick to anything. Very disappointed. In my pictures you can see how much it moves
            Response from InstaTrimMay 17, 2021
            We are sorry your InstaTrim did not perform for you. A common reason for failure is not applying enough consistant pressure to ensure the adhesive has bonded to the application surface. If as section has not been pressed on the application surface properly it will start to come off and can cause the remainder of the InstaTrim to fail.

                excellent look and ease of use
                I have arthritic hands but this was easy to press into place, has an excellent outcome, and refined look and feel. SOOO much nicer than "just a solid bead of caulk"

                  It is a fantastic idea, but it has started to separate from the walls and not sure if it exactly works as seen in the videos. I was hoping it would work great for the problem I was having. I guess I might have to explore more options now.
                  Response from InstaTrimMar 9, 2023
                  Please accept our apologies for the failure of your InstaTrim.
                  A couple of things that might cause failure are, silicone or waxy residue as the adhesive will not stick to silicone or waxy residues, a firm consistent pressure needs to be applied to allow the adhesive to fully bond with both surfaces.
                  Without knowing more about where you installed your trim it is hard to say what may have caused it to fail.
                  Regards, InstaTrim Products.

                  Trim for a property
                  Expensive for what you get. It shrinks after being installed then corners don’t match up & leaves a gap.
                  Response from InstaTrimOct 24, 2022
                  Our apologies you had a bad experience with InstaTrim.
                  InstaTrim will shrink back if stretched during installation as it will want to confirm to it's original size. It should be cut to the just over required length and pushed into place without stretching. You can then trim off any excess.
                  Regards, InstaTrim Products.
