Product 302 Specification Sheet

DESCRIPTION: Enviro-Coat Roof Coating is an acrylic latex roof coating that creates a durable sun reflective coat. The reflective value of this product helps to reduce interior temperature and protects the roof and roofing membrane by reducing heat absorption, asphalt oxidation and rapid thermal dimensional changes. It also decreases the chance of excessive loads placed on cooling equipment. 
USES: Enviro-Coat Roof Coating is specially designed to provide a tough weather resistant and decorative finish for mobile-home tile, bituminous roof surfaces. May be used over de-greased or weathered aluminum, galvanized steel, primed steel, treated unweathered or weathered concrete. This product can also be used on cured cold applied asphalt coatings, smooth surface roofings, most prepared mineral surfaced roofings. 
SURFACE PREPARATION: A clean surface is absolutely essential for proper adhesion of this material. All dirt and unsound accumulations must be removed. Use a good quality chlorinated compound to remove any mildew or algae which may be present. Rinse with water. Where necessary, use brooming and high pressure water hosing to clean the base surface. Allow water to completely dry before proceeding. Roof substrate must drain within 48 hours. There should not be any standing water. Smooth-Surface Roofing: Must be 6 months old or more. Clean and prime first with 1 gallon per 100 square feet primer and allow to dry before application of finished white or tinted surfacing. Granule Surface: Must be clean, sound surface with no loose or foreign material. Best results can be achieved if if surface is slightly dampened or fogged before coating. Metal Roofs: It is important to wire brush and remove rust areas and prime with rust inhibiting primer. All fasteners must be tightly secured or replaced and encapsulated with Elasto-White Patching Cement. All roof seams and flashings must be covered with Elasto-White Patching Cement and membrane reinforcement.
APPLICATION: Stir in container until uniform in color and consistency. For Brushing: Use a soft nylon bristle broom or brush and apply with long even strokes. Avoid over-brushing. Do not attempt to retouch while film is drying. Wait until cured before applying second coat. For Roller: Medium to long nap for textured or rough surfaces. For Spray: Airless spray system with a minimum working pressure of 3000 PSI. Coverage rates will vary depending on porosity of surface as well as roof pitch. One coat can suffice. However, two coats are recommended for maximum reflectivity, durability and life cycles. 
Recommended Coverage Rates: (1)Mineral Surfaced Roll Roofing - 3 gal/ 100 sq. ft.; (2)Metal Roofing - 1 to 2 gal/100 sq. ft.; (3)Concrete Tile or Smooth Roll Roofing - 1.5 to 2 gal/100 sq. ft. Recommended application is two coats (1/2 of above coverages for each coat) applied at right angles to previous coat by brush, roller or spray. First coat must dry before second coat is applied. During application, keep tools clean and free from coating build up by rinsing frequently with water. Do not apply over uncured cold applied asphalt coating, wooden shingles, shakes, flood coats of hot melt asphalt or coal tar, or bare or rusted steel. Asphalt must be dull, not glossy. Do not apply unless temperature is 50°F and rising. Do not apply when rain or frost is forecast within 24 hours after application. Conditions of high humidity will prevent curing in the usual four hours. Avoid heavy foot traffic. 
CLEAN-UP: Clean brushes, tools and other equipment with soapy water immediately after use. Dried film may require paint remover.
