Coating Systems:
Primer Coats:
Primer will be determined by service environment and job specifications. Consult your Anchor representative for specific job recommendations.
 
Surface Preparation:
New Work: For best performance on steel, the surface should be blasted to SSPC-SP6 or SSPC-SP10, including the removal of all mill scale. Prior to blasting, remove all flux and scab from welding and grind smooth all rough weld seams and sharp edges. Remove any grease, oil, or dirt with solvent (SSPC-SP1) or chemical cleaner before blasting. The surface should be coated within 24 hours after blasting. Apply over properly primed surface as detailed by applicable specifications.
Old Work: Substrate must be clean, dry and thoroughly degreased in accordance with SSPC-SP1 standards. All damaged areas should be repaired and existing paint should be in good condition. This coating may be applied over most old coatings in sound condition. Check the existing paint by applying on a trial patch and observe overnight for lifting, softening, or wrinkling. If this occurs, the existing paint must be removed or a compatible barrier primer must be applied first. Glossy surfaces should be sanded or brush blasted for best performance.
