Directions For Use:
Weather Conditions: Surface and air temperature should be a minimum of 45°F but not greater than 95°F at the time of application. Do not apply if temperature is expected to drop below 45°F within a 24 hour period. Do not apply to frozen or frost covered surfaces. Do not apply to wet or water saturated surfaces and/or when rainfall is expected within 24 hours unless adequate protection with a polyethylene film or its equivalent is provided.Â
Surface Preparation: Surface to be coated must be structurally sound, not loose. Surface must be clean and dry. Protect roof from inadvertent spills. Brush surface to be coated with a stiff poly brush to remove loose particles. Larger cracks and voids can be filled with fast setting patching cement or premium grade, siliconized, acrylic latex caulking. CrownSeal may be applied over top of the caulk before it cures as the siliconized, acrylic latex caulk will cure underneath the product. <
