ASTM D4258 – 05(2017)
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. Here is a summary of some of the published standards with which installers and specifiers of corrosion protection linings should be familiar.
The procedures below are intended to help assure optimum performance of the coating system and suitable zstm adhesion to concrete:.
Subscription pricing is determined by: Please first verify your email before subscribing to alerts. All of these steps were important to ensure the paint finish was smooth, uniform in color, and resilient. Caulk should be applied after priming.
Rooms must be heated in cold, damp weather. Your Alert Profile lists the documents that will be monitored. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
This method is suitable for removal of all visible oil, drawing and cutting compounds, grease, soil, and other soluble contaminants. 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. Wood must be clean and dry.
If the document is revised or amended, you will be notified by email. For exterior surfaces, spackle with exterior grade compounds. Allow the coating to dry at least one week before testing for adhesion. Sand surfaces smooth, taking care to sand with the grain. Proceed to Checkout Continue Shopping.
ASTM D – 05() Standard Practice for Surface Cleaning Concrete for Coating
Adherent mill scale, paint, and rust are not able to be removed by this process. Surface preparation methods as outlined in ASTM D are required if d458 coating system is incompatible. Glossy surfaces should be sanded dull. If these requirements are ignored, the lining can delaminate from the substrate or fail to cure properly. You may delete a document from your Alert Profile at any time. Treat textured, soft, porous, or powdery plaster with a solution of 1 pint household vinegar to 1 gallon of water.
Brush Blasting or Sweep Blasting Includes dry blasting, water blasting, water blasting with abrasives, and vacuum blasting with abrasives. Galvanized metal must weather at least 6 months before coating.

Remove all dust, oil, wax, grease, loose paint, mill scale, rust, dirt, mold, mildew, mortar, efflorensence, sealers, and other surface contaminants. Thoroughly cleanse vinyl siding by scrubbing with a warm, soapy water solution. Small residues of rust and paint may be left in the lower portions of pits if the original surface is pitted. Spackle the drywall defects. Damaged areas must be repaired with an appropriate patching material.
Be advised that any coatings left on the surface to be painted may compromise the service length of the system. To avoid premature lining failures resulting from improper surface preparation, lining specifiers, applicators, and inspectors need to be familiar with these industry standards for surface preparation and to adhere to their principles in practice.

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. Surface Preparation Proper surface preparation can improve the outcome of your coating system.
Already Subscribed to this document. Clean steel using one or more of the nine surface preparations described below.
If the surface is new, test it for pH, many times the pH may be 10 or higher. Established by the Steel Structures Council inthese methods are used throughout the world for describing methods for cleaning structural steel. Check for compatibility by applying a test patch of the recommended coating system, covering at least 2 to 3 square feet.
So many corrosion protection lining projects succeed or fail with the quality of the surface preparation achieved before the d42588 is even installed.
Bare plaster must be cured and hard before application. There was so much to do before I ever opened a can of paint. All nail heads must be set and spackled.
