New Masonry:
Allow new masonry to 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. Treat new masonry with a solution of 1 part BOYSEN® Masonry Neutralizer #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.
Remove all loose, scaling, flaking and peeling off paint using BOYSEN® Paint and Varnish Remover #141, wire brushing, scraping, or water blasting. Let it dry. Sand smooth painted surfaces for improved adhesion. Apply 1 coat of BOYSEN® Chalk Blocker™ for chalking old paint. In case of mildew infestation, treat with a fungicidal wash solution or bleach solution (1:3, laundry bleach to water, respectively) by swabbing or brushing. To ensure proper treatment, allow to stand on surface for overnight before washing off residue. Let dry.
