Procedures include broom cleaning, vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning. Subscription pricing is determined by: We have no amendments or corrections for this standard.
Surface must be free of laitance, concrete dust, dirt, form release agents, moisture curing membranes, loose cement, and hardeners. 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.
All loose mortar and foreign material should be removed from block. Maintenance painting will frequently not permit or require complete removal of all old coatings prior to repainting.
The Four Pillarsof Good Surface Preparation
Be atsm that any coatings left on the surface to be painted may compromise the service length of the system. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Visible deposits of grease or oil must be removed prior to blast cleaning by any method d258 in SSPC-SP 1 or other agreed upon methods. High-pressure water blasting is commonly used to clean substrates.
Brush Blasting or Sweep Blasting Includes dry blasting, water blasting, water blasting with abrasives, and vacuum blasting with abrasives. Rinse carefully and allow to dry. Concrete curing compounds, hardeners, and form release agents may not be compatible with recommended coatings.
Vacuum cleaning, xstm cleaning, water cleaning, air blast cleaning, and steam cleaning are suitable as outlined in ASTM D 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 d2458.
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.
Store finishing lumber and flooring in dry, warm rooms to prevent absorption of moisture, shrinkage, and roughening of the wood. 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. Repeat until the surface is hard.

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.
Drywall should be clean and dry. All loose rust, loose mill scale, loose and other detrimental foreign matter can be removed by power tool cleaning.
If these requirements are ignored, the lining can delaminate from the substrate or fail to cure properly. asttm
ASTM D – 05() Standard Practice for Surface Cleaning Concrete for Coating
Need more than one copy? As the voice of the U. Ensure that knots and pitch streaks are scraped, sanded, and spot primed before a full priming coat is applied. Thoroughly cleanse vinyl siding by scrubbing with a warm, soapy water solution. Check for compatibility by applying a test patch of the recommended coating system, covering at least 2 to 3 square feet.
Prime and paint as soon as possible after surface prep. 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. Thorough washing with an abrasive cleanser will clean and dull in one operation, or, wash thoroughly and dull by sanding. Allow the surface astn dry thoroughly.
Make sure all spackled nail heads and tape joints are sanded smooth and all dust removed prior to painting. Clean off the awtm residue. Patch all nail holes and imperfections with a wood filler or putty and d4285 smooth.
So many corrosion protection lining projects succeed or fail with the quality of the surface preparation achieved before the lining is even installed. You may delete a document from your Alert Profile at any time.
If the surface is new, test it for pH, many times the pH may be 10 or higher. Surface Preparation Proper surface preparation can improve the outcome of your coating system. Treat textured, soft, porous, or powdery plaster with a solution of 1 pint household vinegar to 1 gallon of water. Dull glossy surfaces prior to painting.
Ensure that all surface contamination has been removed by washing with an appropriate cleaner. When viewed without magnification, a Brush-Off Blast Cleaned surface should be free of any visible grease, oil, astk, dirt, loose mill scale, loose paint, and loose rust.
Glossy surfaces should be sanded dull.
