Henry PR575070 Aluminum Roof Coating, Black, 4.75 gal

Highly reflective non-asbestos roof coating. It can reduce the surface temperature of a roof and thus retard the deterioration of the surface. It can contribute to reduced heating and air conditioning costs. Features: Reduces roof surface temperature and prolongs life of roof. Reduces interior temperature in summer - saves air conditioning. Forms a tough, waterproof seal. Use on prepared roll roofing, asphalt built-up roofs, galvanized iron & tin. Usage: Can be used to coat properly prepared smooth surface asphalt built-up, metal and modified bitumen membranes. Produces a bright aluminum roof surface which reflects damaging ultraviolet sunrays. Coverage: Applied at a rate of 1 - 1.2 gallons per 100 sq. ft. Application rate may vary according to the type, age and condition of the surface. Precautions: FOR EXTERIOR USE ONLY. Should be mechanically mixed thoroughly before and during application. DO NOT APPLY IF THERE IS A THREAT OF RAIN, DEW, OR FROST WITHIN 48 HOURS. Do not heat container or store at temperatures greater than 110F. When transporting this product, be sure the pail is secured and the lid is tight. Do not allow pail to tumble as this may loosen the lid and allow leakage to occur. CLOSE AIR INTAKES ON ROOF UNTIL SOLVENTS DISSIPATE. Do not allow water to enter a partially used container. This may result in pressure build up in the container. This coating is not recommended for use over gravel, rubber or PVC sheet roofing, shingles of any kind, or old roofs that are too dry and brittle to withstand the shrinkage stresses that occur after the application of any coating.
