Roof coatings can be applied to a variety of roof surfaces, including asphalt-based (BUR, modified), metal, single-ply membranes (EPDM, Hypalon, TPO, PVC). Be sure to use confirm the product's applicable surfaces on its product page or data sheet or contact your local rep prior to purchasing for your project.

All of United Asphalt products are modified during the manufacturing process for the change of seasons. Therefore, any alterations after the manufacturing process can cause product failure and shorten lifespan. Thinning out any solvent based product is in a direct violation of federal laws and regulations.

A roof coating or primer should not be applied to any surface with a threat of rain within 24 hours.

A roof surface must be fully dry before applying any roof coating or primer. The recommended wait time is 24 to 48 hours. Morning dew should also be allowed to dry before application even if it hasn't rained recently.

Aluminum coating will not perform well in ponding areas due to the accumulation of water, dirt, & debris. This prevents the reflectance of the coating and will work its way under the coating causing delamination from the roof surface.

For each of our products we offer specific application guidelines that will indicate if a primer is required. Check out the Application section on each product page. This information is also available on each product's Data Sheet.

Please refer to the specific product SDS (Safety Data Sheet).
