SURFACE PREPARATION

New Concrete

Allow new concrete to dry for 14-28 days under normal weather conditions before painting. Surface to be painted should be clean and dry, free from oil, grease, dust, dirt, contaminants, and all loose grit and mortar. If neutralizing, treat surface with a solution of 1 part BOYSEN®® Masonry Neutralizer B‑44 diluted in 16 parts water, applying liberally by brush or roller. Let dry overnight before rinsing with water to remove white crystals that form on the surface. Let dry before painting. However, if the concrete has been cured for more than 28 days, there is no need for neutralizer.

Repainting

For repainting concrete with chalky old paint, use a surface conditioner. In case of mildew infestation, treat with a bleach solution (1:3, laundry bleach to water, respectively) by swabbing or brushing. To ensure proper treatment, let stand for 24 hours before cleaning off residue. Let dry.

Drywall Substrates

Install and secure joints as per manufacturer's recommendations.
