Application Systems and Tips Mix paint thoroughly to ensure slickening agents are evenly dispersed throughout the can. All surfaces must be clean, dry and properly prepared prior to painting. Do not apply SC-21 on aluminum. When rolling use only a high-quality short nap (maximum 3/16” nap) roller cover. Apply using thin coats; over-application of this product will virtually assure inadequate coating performance. Previously Painted Surfaces: If the previous coating is in good Information condition, thoroughly sand with 80 grit paper followed by thorough sanding with 180-grit then 220-grit and...
