Substrate Preparation

Proper preparation of the substrate to be coated is often the most critical step in achieving long term coating performance. This crucial step is often misunderstood, trivialized, out-sourced or omitted completely by others in the industry. Prime Coat has the expertise to prepare your substrate properly to conform with NACE, SSPC and ICRI standards. We use a variety of preparation techniques including abrasive, soda, dry ice, shot, grit and soft media blasting, dustless diamond cutting and grinding, and water jetting and cleaning. Our expertise allows us to achieve the required level of preparation while minimizing the negative impact to the work area.
