Questions and Answers for Henry 287 Solar-Flex White Acrylic Elastomeric Reflective Roof Coating 4.75 gal. (16-Piece)

A:  Neil, we don't recommend the application of our acrylic coatings such as Henry 287 directly to wood surfaces like plywood or OSB.

A:  Alina, you can apply Henry 287 to a torch down roof that has a granulated surface. If the surface is smooth you will need to apply Henry 107 Asphalt Emulsion prior to the application of Henry 287. Henry 287 is highly reflective as it reflects 86% of the sun's rays and 72% after 3 years. Applying Henry 287 can save more than $2,300 on cooling costs*. (Savings calculations are based on a 1,900 square foot building in Phoenix, AZ using the DOE Cool Roof Calculator).

A:  Eric, Henry 287 cannot be tinted. However, we do make Henry 288 Solar-Flex Desert Tan which can be special ordered at the pro-desk in any Home Depot. Henry 288 should be just the product you are looking for.

A:  James, the only roof coating that we recommend for RVs, trailers, campers and motorhomes is Henry TropiCool 100% Silicone roof coating. The roofs of RVs experience additional stresses that a normal roof does not, such as excess movement, wind peel and wind lift. Because of these stresses the coating must create a very strong bond. Henry 887 forms a chemical bond to the roof as opposed to the weaker physical type bond that acrylic coatings do. I guess that is the long winded way of saying that Henry 287 should not be used to coat the roof of an RV.

A:  Mike, traditionally no primer is needed for the application of Henry acrylic white roof coatings. You can apply a base coat of Henry 107 Asphalt Emulsion Sealer and Damp-proofer at the rate of 3 to 4 gallons per 100 square feet. The emulsion coat must be fully cured before applying the Henry 287, usually 3 to 7 good drying days.

A:  RayRayxray2, you can spray Henry 287 Solar-Flex. You will need a rig that can produce 1,000 to 1,500 PSI and spray one to two gallons per minute. You will need a .030 to a .040 tip for the spray gun.

A:  Justin, you probably could paint the Henry 287 Solar-Flex White roof coating but that would completely defeat the purpose of applying it in the first place. Henry 287 is designed to be very reflective in order to protect the roof from the sun's harmful UV rays and to cool the interior of the structure. As a side note, most paints contain hardeners and are usually not elastomeric, which could result in crazing or cracking.

A:  William, the coverage rate for all of our acrylic white coatings is 100 square feet per gallon or 475 square feet per 4.75 gallon bucket. Two coats is required. Coverage may vary slightly with how rough or how dried out the roofing surface is.

A:  DJantz, to apply Henry 287 Solar-Flex Acrylic White coating you should use a deep pile paint roller such as a 1/2" to a 3/4" nap roller.

A:  Arizonajazz, from your comments we assume that you are planning to coat the roof as well as the sliders of a motorhome or RV. The only roof coating that we recommend for motorhomes, trailers and RVs is Henry 887 TropiCool 100% Silicone because of it's particular bonding characteristics. Henry 887 forms a chemical bond that is much stronger than the physical bond that acrylic coatings such as Solar-Flex form. The stronger bond is needed due to the extra stresses that a moving roof encounters that stationary roofs don't have to deal with. Henry 887 is also waterproof whereas most of the acrylic coatings are not.
