Preparation of Substrate: Surface must be pressure washed clean, free of all loose particles, dirt, debris and other contaminants that could inhibit adhesion. Wire brushing may be recommended in addition to pressure washing the surface. The surface must be completely dry to prevent blistering of the product. Refer to the Armour Proof Coatings Specification for detailed instructions on how to prepare the specific substrate.
Limitations and Precautions: Do not apply when temperature is below 40°F during application or drying time. Apply product when relative humidity is below 90°F. Allow for adequate dry times between coats and inclement weather. Higher humidity or lower temperatures will slow down dry times.
