    Answer This Question

    A:  Andy, you should be able to use Henry 885 TropiCool 100% Silicone Wet Patch Roof Leak Repair Sealant on aged EPDM. With membrane roofs it is always a good idea to do an adhesion test prior to doing all of the repairs since EPDM is difficult for most products to adhere to.

        A:  MichaelJay, you probably could use Henry 885 TropiCool for that purpose. You would be better off using Henry 900 Construction Adhesive and flashing sealant to seal the gaps. Henry 900 is an adhesive as well as a sealant and specifically designed to seal gaps between two dissimilar surfaces.

          Answer This Question

          A:  Lillotus1212, you could probably use Henry 885 for that purpose or Henry 887 TropiCool 100% silicone roof coating but we would not warranty it for that purpose. You could also use Henry 107 Asphalt Emulsion to coat the fish pond since it won't harm the fish. Henry 107 is a black product.

                  Answer This Question

                  A:  Joey, Henry 885 should work just fine on an aged rubber roof to stop or repair roof leaks. Henry 885 is a moisture cure product and does not contain solvents so it won't harm the rubber roof.

                    Q:I have a rubberized aluminum coating on my flat roof and am getting leaking in areas with ponding water. After sealing the leaks I'd like to apply another layer of roof coating. Will 885 (or any silicone alternatives) adhere to the rubberized aluminum?

                    Answer This Question

                    A:  Rachel, if the rubberized aluminum is Henry 869 Rubberized Aluminum then you can use Henry 208R or Henry 209XR to seal the leaks. Henry 885 100% silicone will not be compatible with a solvent based product like Henry 869.
