POLAPRIME 2
Penetrating Primer & Sealer. Enhanced Adhesion for Challenging Substrates.
POLAPRIME 2 is an aquaborne PVC/acrylic primer and sealer engineered to improve adhesion over asphaltic and cementitious surfaces. Designed to penetrate deeply into porous and weak substrates, it coalesces within the surface to strengthen and stabilize the material—creating an ideal foundation for subsequent coating systems.
By consolidating fragile surfaces and sealing internal voids, POLAPRIME 2 enhances both cohesive and adhesive performance. It reduces the risk of pinholes, bubbling, and coating failure while promoting a strong, uniform bond between the substrate and topcoat. Its fast-drying formulation minimizes downtime and helps prevent contamination from dirt or changing weather conditions during application.

Preparation and Application
Surface Preparation
Surfaces must be free of dirt, loose debris, oil, grease, or other substances that would interfere with bond. It is advisable to have the surface as dry as possible. All repairs of damage or defects must be made prior to coating.
Application
Application temperature must be above 45°F (air temperature) and the surface temperature must be 5° above dewpoint for thorough drying to occur. Drying time is in the range of 10 to 30 minutes, depending on temperature and humidity.
Stir thoroughly for 3 minutes, then keep the can covered whenever possible to prevent contaminating the primer.
Apply by spray, roller, or brush. Roller and brush techniques provide best penetration and performance results. For roller application, use a medium or short nap roller. For brush application, use a nylon bristle brush. Apply POLAPRIME 2 only to cover the surface. It is not advisable to pour POLAPRIME 2 straight onto the surface. Apply the appropriate surface coating as soon as possible after thoroughly drying to prevent contamination of the surface, ideally within 2 days. If the POLAPRIME 2 has been left exposed for more than 7 days, the surface must be cleaned thoroughly to remove all dirt and contaminants.
As soon as the POLAPRIME 2 is touch-dry, it may be coated immediately.
Spray Application
Utilize a 30:1 airless pump, a 3/8″ hose and a 19 tip
Recommended Thickness
3 mils Dry Film Thickness (DFT) per coat
Dry Time
Approximately 20 minutes at 70°F and 70% RH.
Clean up
Clean tools and equipment with water before the POLAPRIME 2 dries; after that, solvent cleaning may be necessary.
Limitations
Do not apply POLAPRIME 2 if the temperature is predicted to drop below 40°F within 2 hours of completion of application. Do not apply any of the POLAPRIME 2 to saturated surfaces or substrates that have ice crystals entrapped. Do not apply if rain is forecast within 4 hours of completion of application.
