A:  Kathy, if the hole is greater than 1/4" wide you will need to use Henry 183 or 181 reinforcing fabric with it in a 3-course patching method illustrated on the label.

A:  roofy, when applying Henry 887 TropiCool 100% Silicone over a tar based product such as Henry 209XR you will need to let it cure for at least 90 days. In most cases a bleed blocker is not need for Henry 887. If you need to use a bleed blocker you can use Henry 587 Dura-Brite or Henry 687 Enviro-White for that purpose. Our best advice would be to apply a few small test patches of Henry 887 on the roof surface to see if you get bleed through prior to coating the entire roof.

A:  We strongly advise NOT to use a blow torch to make Henry 209XR flow. Henry 209XR is an asphaltic based product and contains solvents.

A:  Skeeterdude, Henry 209XR will work on a metal container roof. You will need to remove the rust and scale with a wire brush prior to the application of Henry 209XR though.

A:  Blue, you can apply Henry 209XR to a torch down roof. For the ponding water areas you can apply Henry 887 TropiCool 100% Silicone roof coating after you clean the ponding areas with water. Henry 887 is permanently ponding water resistant.

A:  Richard, sorry for the delay in answering your question. The system was having problems in late February and this question was just received. Henry 209XR should not be used as a foundation sealer. You can use Henry 101 Non-Fibered foundation coating or Henry 107 Asphalt Emulsion for coating foundations.

A:  John, if you intend to apply Henry 209XR to an area that has Henry 204 on it you will need to remove the 204 first. Asphalt based mastics usually take up to 30 days to harden up since they cure by the slow release of the solvents. Henry 204 is a mastic that should only be applied when the surface is dry. Henry mastics such as Henry 208, 208R and 209XR can be applied in the rain by using the 3-course patch method illustrated on the can label. Since roofs move a lot due to the temperature changes a patched area will probably open back up unless the Henry 181 or 183 Fabric is used. The 3-course patch method is a layer of mastic, embed the fabric over the seam, apply a second layer of mastic over the fabric.

A:  Davey, Henry 885 TropiCool 100% Silicone Seam and Repair Sealant is a really great roof repair product. Henry 885 is ready to use out of the can and can be applied by brush or trowel.

Henry 885 also offers excellent adhesion to a wide variety of building materials.

( A layer of 209XR, a bit of fabric embedded in the 209XR and another layer of 209XR over the fabric.).
