Your Alert Profile lists the documents that will be monitored. Procedures include broom cleaning, vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning. Bare plaster must be cured and hard before application. Following these guidelines will help ensure sufficient adhesion of the coating and can help prolong the life of the coating system.

ASTM D – 05() – Standard Practice for Surface Cleaning Concrete for Coating

This standard is not included in any packages. The surface may be painted after 30 days if recommended procedures for applying stucco are followed, and normal drying conditions exist. When weathering is not possible or the surface has been treated with chromates or silicates, first Solvent Clean per SSPC-SP1 and apply a test area, priming as required.

If these requirements are ignored, the lining can delaminate from the substrate or fail to cure properly. Surface preparation methods as outlined in ASTM D are required if the coating system is incompatible. Make atm all visible grease, oil, salts, and soluble welding residues have been removed before hand tool cleaning by the methods outlined in SSPC-SP 1.

For exterior surfaces, spackle with exterior grade compounds.

Conco Paints – Surface Preparation

All loose mortar and foreign material should be removed from block. So many corrosion protection lining projects succeed or fail with the quality of the surface preparation achieved before the lining is even installed.

Damaged areas must be repaired with an appropriate patching material. All loose rust, loose mill scale, loose and other detrimental foreign matter can be removed by power tool cleaning. Make sure all visible grease, oil, salts, and soluble welding residues have been removed prior to power tool cleaning by the methods outlined in SSPC-SP 1. Here is a summary of some of the published standards with which installers and specifiers of corrosion protection linings should be familiar.

Be advised that any coatings left on the surface to be painted may compromise the service length of the system. The steps below are provided for assistance in properly preparing various common substrates before coating. 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 address many aspects of steel and concrete surface preparation.

Rags and cleaning solution should be changed frequently so that deposits of oil and grease are not spread over additional areas in the cleaning process. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

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. Caulk should be applied after priming. If the document is revised or amended, you will be notified by email. Plan accordingly to handle the runoff. Galvanized metal must weather at least 6 months before coating. Thorough washing with an abrasive cleanser will clean and dull in one operation, or, wash thoroughly and dull by sanding.

All nail heads must be set and spackled.

Wipe off the dust. All of these steps were important to ensure the paint finish was smooth, uniform in color, and resilient. If the surface is new, test it for pH, many times the pH may be 10 or higher. Proceed to Checkout Continue Shopping.

Conco Paints

This practice includes surface cleaning of concrete to remove grease, dirt, and loose material prior to the application of coatings. Visible deposits of grease or oil must be axtm prior to blast cleaning by any method v4258 in SSPC-SP 1 or other agreed upon methods. You may delete a document from your Alert Profile at any time. Hand Tool Cleaning will remove all loose rust, loose mill scale, and other undesired foreign matter. Tape and cover joints with a joint compound.

When viewed without magnification, a Brush-Off Blast Cleaned surface should be free of any visible grease, oil, dust, dirt, loose mill scale, loose paint, and loose rust.

Mill scale, paint, and rust that is tightly adhered to the surface may remain even after Brush-Off Blast Cleaning. Make sure all spackled nail heads and tape joints are sanded smooth and all dust removed prior to painting.

Standards Subsctiption may be the perfect solution. As the voice of the U.

Brush Blasting or Sweep Blasting Includes dry blasting, water blasting, water blasting with abrasives, and vacuum blasting with abrasives.
