A. New Concrete:
All surfaces must be clean, dry, free from dust, dirt, chalk, laitance, efflorescence, rust, grease, oil and other foreign materials.
Allow new concrete to cure and dry completely for at least 28 days with a moisture of pH level below 10
B. Previously Painted Concrete:
Remove mold and mildew growth with DAVIES® 500-X Mildewcide Wash Solution. Rinse with water, dry and immediately apply the recommended paint system to prevent regrowth of mold and mildew.
For surfaces that exhibit severe chalk, apply one coat of DAVIES® 5-530 Liquid Tile Penetrating Sealer.
