    How to Use

    1) Prepare Surface

    To apply, surface moisture content must be less than 25% as measured with an electronic moisture meter. Surfaces must be free of dirt, grime, efflorescence, lime run, construction debris, form oils and release agents, chalked materials, loose and peeling paint, mold, mildew, etc. All cracks should be pointed or caulked. Do not apply if rain, snow, or temperatures below 40°F are expected within 48 hours. Do not apply if relative humidity is greater than 80%.

    2) Apply Product

    Apply with commercial airless spray equipment set at moderate pressures using a tip of .015 to .021. For application to horizontal surfaces, materials may be sprayed or rolled using a short nap roller. To avoid lap marks, maintain a continuous wet edge. Feather edges at the end of each pass. Stop application only at control joints, corners, and edges.

    3) Let Dry

    Product dries in 2 hours and fully cures in 3-4 weeks.
