Using this 20 - inch flat squeegee is easy. First, make sure the surface you're working on is clean. Then, apply the compound you want to spread. Hold the squeegee at a slight angle and move it smoothly across the surface to spread the compound evenly. When using it to erase epoxy or trowel lines, press a bit harder. For finishing drywall or skim - coating walls, use gentle and consistent strokes. As for maintenance, clean the squeegee right after use with water and a mild detergent. Let it dry completely before storing it. Keep it in a dry place to prevent the blade from getting damaged.
