Preparation & Application

Clean
Before coating the roof, use a pressure washer with greater than 2,000 psi to clean the roof with a non-filming detergent,

such as TSP or TSP substitute. Use appropriate pressure and take caution not to inject water into the roofing substrate when power

washing. In areas with stubborn dirt, grease or other contaminants, use a stiff bristle brush or broom to scrub the areas clean with

additional water and non-filming detergent. Treat mildew or mold. Rinse the roof to ensure it is free of all detergent or anything else

that could affect adhesion. Using a leaf blower or broom, clear any remaining dust, dirt, debris or other foreign material that may

prevent proper adhesion.
Repair
Inspect area to be coated. This product is not designed to seal leaks. Repair all cracks, splits and holes by embedding the

Pro Grade 197 with AWS Polyester Fabric using a three course method to waterproof the area. In some cases conventional roofing

methods may be required.

Existing roof membrane, insulation and all substrates must be sound, dry, clean and free of oil, grease, dirt, excess mortar,

frost, laitance, loose and flaking particles, or other contaminants. All leaks must be sealed prior to application of coating.
Apply
Mix coating thoroughly and apply with a heavy-duty sprayer, deep-pile paint roller or roofing brush, keeping strokes in one
direction.
