Using the Metex Flowing Concrete Green Steel Dapple Bar is easy. First, adjust the height of the 90 - degree comfort - grip handles to a level that's comfortable for you. Then, place the bar on the concrete sub - base or footing. Use the handles to move the bar back and forth gently across the surface. This will help you achieve a smooth and even finish. When using it, make sure the surface you're working on is relatively flat. Don't apply too much pressure as it might damage the bar or the concrete. After each use, clean the bar with a damp cloth to remove any concrete residue. Store it in a dry place to prevent rusting. This will keep your dapple bar in good condition for a long time.
