Surface to be coated must be dry* and free of dirt or corrosion particles. AIM 770 Thermoplastic White Roof Coating may be applied to wet surfaces as a temporary repair measure. Its ultra-high density and water displacing abilities allow adhesion to wet and underwater surfaces. Surfaces must be power washed clean with a suitable residue-free detergent. Before applying coating, close all fresh air intakes and other potential points of entry for solvent vapors into the building. For best results, apply the product with a 3/4″ to 1-1/4″ inch nap roller or suitable spray equipment. Apply successive coats at right angles when possible.

Mix the coating thoroughly before application. For best results, maintain coating temperature at 50°F or higher. Roof Temperature should be above freezing during application. Once applied, coating is unaffected by temperature.

Allow 24 hours between coats on asphalt, modified bitumen and EPDM roofs. For all other roof types, allow four hours between primer and/or base coats and the finish coat. All roofs must be cleaned prior to application of this product. Failure to do so may result in poor adhesion and/or discoloration of the coating. For PVC roofs consult the manufacturer prior to use.

Do not use over acrylic roof coatings. Clean up with mineral spirits or waterless hand cleaner. Use care when handling solvents.

For fabric reinforced applications or other roof systems, consult the manufacturer. Granule surfaces may require 2 gallons per coat depending on the irregularity of the surface. For fabric reinforced applications or other roof systems, consult the manufacturer. Typical rate of application with reinforcement is 5 gallons per 100 sq. ft. Granule surfaces may require 2 gallons per coat depending on the irregularity of the surface.

*Roof surfaces must be dry for coating application. Even when the surface appears dry, moisture trapped in the roof, deck or insulation. A moisture scan is recommended prior to application. In addition. Application of this coating within 5ºF of the dew point is not recommended.

**The first coat over asphalt will often stain yellow. Although AIM 770 Thermoplastic White Roof Coating is highly resistant to asphalt staining, this condition is unpredictable. If brown spots appear during application with a roller, inspect the roller nap for embedded pieces of asphalt. These spots will be covered by the second coat. Uneven, alligatored or cracked roofs will require the higher rate of application.

***EPDM roofs may exhibit temporary swelling if application rates are significantly exceeded. If swelling occurs do not proceed with additional coats until it has subsided.

Certain PVC roofs may contain plasticizers that can soften AIM 770 Thermoplastic White Roof Coating. Applicator is responsible for determining the type and manufacturer of the roof to be coated. If unsure of the type of roof system to be coated, consult AIM to obtain positive identification.
