Q:Can this be applied over a shingle roof with a couple of leaks in different spots?
by|Sep 21, 2023
1 Answer
Answer This Question

A:  Geary, some people have applied Henry 887 TropiCool 100% silicone to shingles but we do not recommend it and we will not warranty it for that purpose. For leaks you should use a leak stopper such as Henry 208R, 209XR or our clear patch - Henry 212 Crystal Clear Patch. Henry 887 TropiCool is a roof coating that is meant for use on flat or very low slope roofs.

    Q:1. Can this be applied over a tar roof? 2. How do you recommend to clean a roof to prep for this?

    Answer This Question

    A:  DIYit, a roof that has a tar coating presents adhesion problems for most products. Henry 885 TropiCool 100% Silicone Wet Patch would probably not stick to the surface. If you are patching leaks or potential leaks you can use Henry 208R or Henry 209XR instead of the silicone.

      Q:Once 885 is applied and cured, will I be able to walk on it? I am coating a low slope portion of my roof, which is also how I typically gain access to the roof. Thanks.

      A:  Ryan, although Henry 885 is not meant for regular foot traffic you can walk on it to do regular maintenance on your roof. Just be very careful and don't walk on it if it is wet.

        A:  Absolutely not. Contrary to the video on the product detail page, this product has the consistency of cookie dough and is trowel application only.

          A:  Mike, you can use a brush or a trowel to apply Henry 885 which makes it a very easy patching product to apply. You can typically coat over the 885 with Henry 887 in about 24 hours depending on the humidity. The higher humidity the faster the Henry 885 will cure since it cures by pulling water molecules out of the air.

            Q:I applied 887 to RV roof but it wasn't quite enough. What is needed to apply 2nd coat and finish the transition from the newly coated area to the uncoated area?

            A:  David, all you need to do here is make sure that the surface is still clean. If it has been more than 24 hours since the first coat you will need to wash the roof again with water. Once the roof is dry you can just start applying Henry 887 where you left off and then apply the second coat.

                A:  TI42, Henry 885 TropiCool 100% Silicone Wet Patch Repair Sealant should work just fine on an EPDM trailer roof that has been weathered. Just make sure that the area to be patched is clean.

                  Q:Can you coat over eternabond tape on an rv with Henry 100% silicone roof coating?

                  Answer This Question

                  A:  TimW, we have not tested Henry 885's adhesion to Eternabond tape. While there are a number of Eternabond tapes it seems like they are a PVC or plastic coated product. You would need to apply a small amount of Henry 885 to it and wait a couple of days to see how good it sticks to the tape. Eternabond is not a surface that we would warranty the 885's performance on however.

                    Q:If I could only choose one product out of Henry 885 or 887 to repair and seal a roof - in 1 coat, which one would be recommended? I am leaning towards 885 as it can both repair and seal, and has some UV protection. Your thoughts?

                    Answer This Question

                    A:  anjc, Henry 885 and 887 are two distinctly different products that are for different issues. Henry 885 is a patching sealant that is thick and is used to repair seams, cracks, holes, splits and to seal around any surface penetrations. Henry 887 is a coating that protects the roof from wind, rain, snow and the sun. It is waterproof and highly reflective and will last for a lifetime. If cost is an issue we would recommend patching all of the seams and any roof penetrations with Henry 885 so that you don't have any leaks rather than trying to seal leaks with Henry 887.

                      A:  ajc09, you could use Henry 885 for your project. However, you would be better served by using Henry 900 Construction and flashing sealant. Henry 900 is gray in color, very flexible and will last a lifetime.
