Surface Preparation

All surfaces must be clean, dry and free of dirt, oil grease, and other contaminants. High pressure washing with detergent is preferable. However, washing with a suitably diluted solvent alkaline cleaner or equivalent liquid detergent is adequate, provided that sufficient scrubbing to loosen contaminants is done and if followed by a through rinsing. After cleaning, all surfaces must be allowed to dry completely.

One year, protect from freezing in shipment and storage.


Mix thoroughly before using. Slight separation may occur during storage. 6:4 UV Stable Polyaspartic is a ready to use material. It can be spray applied using a Hudson type ag sprayer, as well as through conventional or airless spray equipment. Safety glasses with side shields and latex gloves are recommended when transferring from the shipping container to the sprayer. If using a Hudson, adjust spray nozzle to achieve a uniform spray pattern with a 3-4 foot area. If using an airless spray less equipment, use a .015-.019” reversible tip with a 40-50°F fan angle.
