  • Remove mildew stains with a mildew stain removing product.
  • Scuff sand glossy and metal surfaces and repair imperfections.
  • Remove all dust with a damp cloth, allow to dry.
  • Allow new masonry stucco, concrete, concrete masonry units (CMUs), and split-faced block to cure for 7 days and test pH prior to applying primer.
  • The pH must be 13.0 or lower before coating.
  • Remove efflorescence with a mixed solution of one part vinegar and one part water, rinse thoroughly with clean water and allow to dry.
