#911 ETERNALASTIC ELASTOMERIC ROOF COATING

Surface must be clean and dry, free of moisture both on and beneath the surface. Pressure wash roof thoroughly to remove as much dust, dirt, and debris as possible. After careful inspection of entire roof, repair all holes, cracks, tears or breaks with reinforcing fabric and #950 Eternamastic. #950 Eternamastic repairs can usually be coated within 24 hours. Coat newly applied asphalt emulsion as soon as the emulsion can take foot traffic without scuffing the surface, normally 7–10 days.

Apply on warm, sunny days, preferably in the morning hours to provide maximum cure time. #911 Eternalastic can be applied to a dry or slightly damp, but not wet, surface. Water must be swept out of all puddles prior to application of #911. Stir #911 thoroughly before application to achieve a uniform consistency. Apply with a heavy-duty paint roller or heavy duty spray equipment. When applied with roller or brush, strokes should be kept in one direction. Apply second coat perpendicular to the first. Allow at least four hours between coats and 24–48 hours for full cure, dependent upon weather conditions. Relative humidity will directly affect drying/curing time. Avoid over application.

Apply at a minimum rate of 1-1.5 gallons per 100 square feet per coat dependent upon roof porosity. Two coats are required, for a minimum total of 3 gallons per 100 square feet.

DO NOT APPLY IF TEMPERATURE IS BELOW 50° F OR ABOVE 110°F. DO NOT APPLY IF THERE IS A THREAT OF RAIN OR DEW WITHIN 48–72 HOURS. DO NOT ALLOW TO FREEZE. DO NOT THIN. DO NOT HEAT CONTAINER or store at temperatures greater than 120°F. Be sure the lid is tight and the pail is secured when transporting this product. Do not allow pail to tumble as this may loosen the lid and allow leakage or spillage to occur. This coating is not recommended for areas with inadequate drainage (ponding water), over gravel, over walking decks, or old roofs that are too brittle and dry. DO NOT APPLY TO FLAT SURFACES WITH POOR DRAINAGE OR WHERE PONDING WATER WILL EXIST.

Clean with mineral spirits or paint thinner.
