4.75 Gal. Acrylic Reflective Elastomeric Roof Coating

Chris, the answer is no this is not the product that you want to seal screw heads. Acrylic roof coatings are mainly to reflect the sun's harmful UV light and heat. If you want to seal the screw gaskets the best bet is Henry 885 Seam Sealant and then coat with Henry 887 TropiCool 100% Hi-solids silicone. Henry 885 and 887 not only reflect the heat and sunlight but are both waterproof and last a lifetime. Thank you for putting your trust in the Henry co and the Home Depot.

Basspig, I stated in an earlier answer that you should test Henry 887 TropiCool on your roof to test the adhesion. Any acrylic coating will most certainly not stick to an EPDM surface and will be a waste of time and money. Please check my earlier answer for best practices for this project.

Sandro. Applying Henry Acrylic white coating won't hurt the wood but we don't recommend that application. Henry White coatings are designed to be applied to regular roof substrates like roll roofing or torch down. Wood has additional movement issues than regular roof substrates. Wood swells and shrinks with the humidity and rain. Most products applied to wood are done with staples or large headed nails so that the felt paper can sustain a slight movement from the wood without tearing. It is for those reasons that we would not suggest coating wood with an acrylic coating.

Papu, traditionally we do not recommend tinting our acrylic products as it will void the warranty. I have heard of some customers tinting the product but I am not sure of what the make up of the tinting product is and how compatible it is with the coating. Thank you for your trust in Henry products and the Home Depot.

Cesar, generally a 4.75 Gallon bucket will cover about 500 square feet. However you will need to take into account the "thirst" of the roof surface. It depends on the age of the roof surface or if it has a smooth or granulated surface. The first time you apply an acrylic you must do two coats, one applied east and west and the second applied north and south for example.

I have used it on my RV and it works fine.

Yes, it can. Just be sure the concrete is very dry and as clean as you can make it. If it's really troweled smooth, then not a bad idea to wire brush the surface prior to application if you can.

Dave-we do not recommend this coating for those types of roofs. Thank you for putting your trust in the Henry Company and The Home Depot.

Dann-we have heard of people doing this; however, we only recommend and/or warranty the product when it is applied to a roofing material that is part of a roofing system. Thank you for putting your trust in the Henry Company and The Home Depot.
