A. Concrete Surfaces

New Painting

• All surfaces must be clean, dry, free from dust, dirt, chalk, laitance, efflorescence, rust, grease, oil, and all other foreign materials.
• Allow new concrete to cure and dry completely for at least 28 days with a moisture content of less than 15% and a Ph level below 10.
• To neutralize and remove efflorescence, treat surfaces with Davies DV-100-X Concrete Neutralizer diluted with 16 parts water to 1 part DV 100-X. Apply by brush or mop to wet surface thoroughly and dry overnight. Rinse with water and dry.
