The success or failure of a paint system rides on the standard of the surface's preparation. The best paint or coating can fail on a poorly prepared surface. And the simplest and cheapest paint can perform better than expected on a well-prepared surface.
What should a good surface preparation provide?
Blastrite has a comprehensive offering of painting preparation media and equipment. Review our abrasives and painting preparation products under the products list, or download the latest product brochures from our Downloads section.
Studies show that pre-treatment before coating application is the single most decisive factor impacting lifetime (and thus cost-effectiveness). Poorly pre-treated surfaces with contamination and insufficient blast cleaning result in reduced coating adhesion, blister formation and ultimately corrosion under the coating.
