ASTM D() – Standard Practice for Surface Cleaning Concrete for Coating
Here is a summary of some of the published standards with which installers and specifiers of corrosion protection linings should be familiar. Prime and paint as soon as possible after surface prep. When viewed without magnification, a Brush-Off Blast Cleaned surface should be free of any visible grease, oil, dust, dirt, loose s4258 scale, loose paint, and loose rust.
When viewed without magnification, a White Metal Blast Cleaned surface should be free of any visible grease, oil, dust, dirt, mill scale, paint, rust, axtm, corrosion products, and other foreign matter. Adherent mill scale, paint, and rust are not able to be removed by this process. This method is suitable for removal of all visible oil, drawing and cutting compounds, grease, soil, and other soluble contaminants. Damaged areas must be repaired with an appropriate patching material.
Ensure that knots and pitch streaks are scraped, sanded, and spot primed before a full priming aetm is applied. Method of cleaning steel to remove dirt, oil, grease, loose rust, loose mill scale, and loose paint using water at pressures of 2, to 2, psi at a flow of 4 to 14 gallons per minute. For concrete and steel substrates, a prepared surface is typically one that is clean, dry, structurally sound, and possesses a certain surface profile—the four pillars of good surface preparation.
There was so much to do before I ever opened a aztm of paint. Hand Tool Cleaning will remove all loose rust, loose mill scale, and other undesired foreign matter.
Remove all dust, oil, wax, grease, loose paint, mill scale, rust, dirt, mold, mildew, mortar, efflorensence, sealers, and other surface contaminants. High-pressure water blasting is commonly used to clean substrates.
Check for compatibility by applying a test patch of the recommended coating system, covering at least 2 to 3 square feet. Store finishing lumber and flooring in dry, warm rooms to prevent absorption of moisture, shrinkage, and roughening of the wood. Make sure all visible grease, oil, salts, and soluble welding residues have been removed before hand tool cleaning by the methods outlined in SSPC-SP 1. Vacuum cleaning, broom cleaning, water cleaning, air blast cleaning, and steam cleaning are suitable as outlined in ASTM D You can download and open this astk to your own computer but DRM prevents opening this file on another computer, including a networked server.
Allow the surface to dry thoroughly.
Thorough washing with an abrasive cleanser will clean and dull in one operation, or, wash thoroughly and dull by sanding. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. To test compatibility, apply a square foot area with the coating system, and allow concrete to dry one week before testing adhesion per ASTM D Caulk should be applied after priming.
The room must be ventilated while drying. Mill scale, paint, and rust that is tightly adhered to the surface may remain even after Brush-Off Blast Cleaning. As critical as these steps are, it should come as no surprise that there is a wealth of technical standards available from organizations such as NACEASTMand SSPC which aetm many aspects of steel and concrete surface preparation.

Rinse carefully and allow to dry. Bare plaster must be cured and hard before application.
Standard Practice for Surface Cleaning Concrete for Coating
Patch all nail holes and imperfections with a wood filler or putty and sand smooth. Use an appropriate primer to spot prime any bare ares. Staining to be cleaned may consist of light shadows, slight streaks, or minor discolorations caused by stains of rust, mill scale, or previously applied paint.
The procedures below are intended to help assure optimum performance of the coating system and suitable coating adhesion to concrete:. If the surface is new, test it for pH, many times the pH may be 10 or higher. Following these guidelines will help ensure sufficient adhesion of the coating and can help prolong the life of the coating system.
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. The surface to be coated must be clean and c4258 of contaminants, oil, loose cement, mortar, and grease. All of these steps were important to ensure the paint finish was smooth, uniform in color, and resilient.
