Lucas #648 Aluminum Roof Coating is designed to provide a reflective surface for roofs, metal buildings, tanks, and mobile homes. Aluminum pigmented asphalt coating can substantially reduce interior building temperature and prolong roof service life. Lucas 648 is formulated from specially refined asphalt, aromatic and aliphatic solvents. Light brushing viscosity allows for quick and economical coverage
APPLICATION
Surface to be coated must be dry and free of dirt or corrosion particles. It will be helpful to turn the pails upside down 24 hours prior to application so that the settled aluminum releases from the bottom of the pail. Before mixing pour 50% of the liquid contents into a clean 5 gallon pail. All of the aluminum should remain in the original pail. Mix the aluminum into the liquid contents. When it is free of lumps, add back the liquid from the second pail and mix until uniform. Mechanically mix coating thoroughly and continuously before and during application. Power mixing is recommended, a square bladed drywall mud mixer and 1/2 inch drill is recommended for 5 gallon pails. Apply evenly with a soft bristle brush or suitable spray equipment at the rate of not less than one half and not more than three quarters of a gallon per 100 square feet. For best results, brush coating in one direction with the slope of the roof. Do not apply over fresh roof repairs or coating. Roofing asphalts, both hot and cold applied, contain oily constituents which may bleed through and stain the finished coating. As this condition is unpredictable, we recommend that the user apply a small amount of #648 to the area of the roof to be coated in order to test its performance. Use #648 as it comes from the container, no thinning is necessary with this product. 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. Application of this coating within 5ºF of the dew point is not recommended.
