Pressure-wash the existing roof surface to remove dirt, dust, and contaminants, ensuring maximum adhesion to the substrate. If the SPF layer is exposed for more than 24 hours, Acrylic Bonding Primer 905 may be required to promote proper adhesion.

Apply a high-density, plural-component spray polyurethane foam (SPF) layer based on the substrate at varying thicknesses. This lightweight yet durable insulation barrier enhances thermal performance and structural integrity. For SPF system recoats, the existing spray polyurethane foam layer must be restored to the original manufacturer’s specifications before additional coatings are applied. Contact Technical Services for product information.

Apply an elastomeric coating directly over the SPF layer, selecting from Acrylic 211, High-Tensile Acrylic 211, Silicone 410, High-Solids Silicone 412, Aliphatic Urethane 510, Aromatic Urethane 520 based on project requirements. The base coat is commonly tinted gray, tan, or ivory to assist with uniform application. The top coat forms a seamless, bright white membrane that delivers superior UV protection, reflectivity, weather resistance, and ponding water resistance.

Broadcast Roofing Granules into the elastomeric top coat to enhance durability, weather resistance, and impact protection.
