New concrete should dry for 14 to 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 painting must be done immediately after the 14-day curing period, treat with a solution of 1 part Dutch Boy® Nalcrete™ Masonry Neutralizer 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 28 days or more, there is no need for neutralizer.
