Here ast, a summary of some of the published standards with which installers and specifiers of corrosion protection linings should be familiar.
Surface must be free of laitance, concrete dust, dirt, form release agents, moisture curing membranes, loose cement, and awtm.
Repeat until the surface is hard. The surface may be painted after 30 days if recommended procedures for applying stucco are followed, and normal drying conditions exist. Some composition boards may emit a waxy material that must be removed with a solvent prior to coating.

Brush Blasting or Sweep Blasting Includes dry blasting, water blasting, water blasting with abrasives, and vacuum blasting with abrasives. Rinse with clear water and allow to dry.
Bare plaster must be cured and hard before application. Rinse carefully and allow to dry. When weathering is not possible or the surface has been treated with chromates or silicates, first Solvent Clean per SSPC-SP1 astn apply a test area, priming as required. This standard is also available to be included in Standards Subscriptions. If necessary, pressure clean with a minimum of psi to remove all dirt, dust, oil, grease, laitance, loose particles, foreign material, and peeling or defective coatings.
Check for compatibility by applying a test patch of the recommended coating system, covering at least 2 to 3 square feet. Exterior composition board siding hardboard must be thoroughly cleaned and primed with an alkyd primer, whether factory primed or unprimed.
All of these steps were important to ensure the paint finish was smooth, uniform in color, and resilient. Thoroughly cleanse vinyl siding by scrubbing with a warm, soapy water solution.
