Surface Preparation

The performance of a coating is affected by proper surface preparation; it is the foundation that a coating system is built on. Coating integrity and service life will be reduced because of improper surface prep. The selection and implementation of proper surface preparation ensures coating adhesion to the substrate and a lengthy service life. Imms Industrial Coatings Inc. offers all of the following options:

  • Hand tool cleaning: The removal of contaminates, loose corrosion, and paint by hand chipping, sanding, scraping, or wire brushing.
  • Power tool cleaning: The removal of contaminates, all corrosion, loose mill scale, and loose paint by power tool chipping, decaling, sanding, wire brushing, or grinding.
  • Water blasting: The removal of oil, grease, dirt, loose corrosion, loose mill scale, and loose paint to a degree specified at pressure of 2500-5000 psi.
  • Wet Abrasive Blasting: Blast cleaning to a specified degree that utilizes abrasives mixed with water to reduce nuisance dust and to clean contaminates from the substrate surface.
  • White metal blast: Total removal of oil, grease, visible corrosion, mill scale, and paint by blast cleaning with abrasives, grit, or shot.
  • Near white blast: Blast cleaning to 95% of a white metal cleaning with the surface area is free of all visible residues and corrosion. Light and shadows and minor discoloration are acceptable up to 5% of each square inch or surface.
    Commercial blast: Removal of all contaminates to at least 66% of each square inch of abrasive blasted area. Slight shadows are acceptable.
  • Brush off blast: Abrasive blast cleaning and removal of oil and grease except for tightly adhered residues, mill scale, and corrosion.
  • Solvent cleaning: Removal of oil, grease, salts, and containments by cleaning with solvent, emulsifying agent, steam, or cleaning compound.
  • Bristle blasting: With the use of a specialty power tool the surface of the substrate is treated by a brush-like rotary tool with a wire bristle wheel. The results, with repeated contact, create steel, free of paint, mill scale, and corrosion. This technique does not require abrasives or chemicals and will achieve a blast profile comparable to a commercial blast.
