Do not use near open flame. Avoid breathing solvent fumes and prolonged contact with skin.Do not take internally. If swallowed, do not induce vomiting. Call a physician immediately. Keep out of reach of children. Store in a heated room and keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying. Exterior use only. Cold-process systems and coatings, either emulsion or solvent-based, should only be installed on decks with positive drainage. Per NRCA (National Roofing Contractors Association), “The criteria for judging proper slope for drainage is that there be no evidence of standing water on a deck 48 hours after it stops raining.”
