Overview

Model # HE487623 Store SKU # 1001311103

Henry 487 100% Silicone White Roof Coating is a premium, 100% silicone, moisture-cure coating designed to protect many types of roofs as well reflect the sun's heat and UV rays. While suitable for use in all climates, the 100% silicone chemistry is especially suited for extreme environments, which are exposed to some of the hottest and wettest weather with intense UV exposure. It is specially designed to maintain maximum weatherproofing, and reflectivity of heat and UV rays as it ages. Its moisture-cure chemistry creates a very aggressive chemical bond with the roof, which allows for permanent ponding water resistance, extreme durability, and superior capabilities of sealing and protection.

Can I use this product be used to "paint" the surface of polycarbonate roof panels similar to Suntuf products? I would like to add something that helps prevent minor leaks around the screw fasteners and to block more of the sun. Thanks

Asked by: Robert
Hi, Thank you for this question. HE487 silicone roof coating should adhere fine to clean, dry polycarbonate panels, however, it is recommended you do an adhesion test to make sure you are satisfied with the adhesion to the surface.

Is this product suitable for a living space roof such as the top of a houseboat. Can it take foot traffic?

Asked by: bestdj
The HE487 100% silicone roof coating would not be recommended for this application on top of a Houseboat as it is very slippery when wet and is also not made for foot traffic.
