VFI-690 Waterproofing Primer comes ready to use; however, it is recommended that the container be shaken or stirred before application. Apply VFI-690 Waterproofing Primer by brush, roller, or airless sprayer to the recommended coverage rate. Allow each coat to dry before proceeding with additional coats.
Coverage may vary due to the porosity of substrate. Apply at a maximum rate of 180 sq. ft./gal. A minimum thickness of 5 mils per coat should be maintained. Allow 8 hours between coats in temperatures of 70ºF and above (at lower temperatures, more drying time may be needed)
