The success of any coating application is directly proportional to the completeness of the substrate preparation and the care the application crew puts into the application. Surface must be clean and sound. Verify that the temperature of the surface is at least 3 degrees C (5 degrees F) higher than the dew point temperature to preclude condensation. Metal: Before preparing steel, please inspect and remove oil, grease, or other contaminants – “Solvent Cleaning” (SSPC-SP1) may be required. Grind any weld spatter or steel weld inconsistencies. Abrasive blasting (or other approved mechanical methods) to SSPC SP-10/NACE No.2 “Near White Blast Cleaning” must be used in order to achieve a clean surface with a minimum profile of 2.5 mils; remove dust and debris by high compressive air or solvent cleaning (SSPC-SP1) may be require again. Epoxytec’s A1 Primecoat is advised as a primer should the substrate be susceptible to flash-rusting, to stripe coat any edges or bends in the metal, or should the metal not possess the characteristics to achieve optimal profiling capability. Wood: Remove all loose particles, rot, and soft spots. The area to be coated should be sanded and rinsed. Allow time to dry thoroughly. When applying to wood, Epoxytec’s B2 Primecoat is required. Concrete: Remove all oil, dirt, and contaminates and prepare the concrete by abrasive blasting, high pressure water blasting, jetting and/or approved mechanical methods to SSPC SP-13/NACE No. 6 “Surface Preparation of Concrete.” Surface should be dry and free of dust. Although primers are optional: should the substrate prove to be excessively outgassing, the Epoxytec’s B1 Primecoat is recommend to reduce the occurrences of pinholing. The Epoxytec B2 Primecoat would be advised for substrate surface conditioning and enhancement.
