Finishing the edges of an Irish Black Granite countertop is typically done using a diamond polishing pad and water. Here is a step-by-step guide to help you finish the edges:
1. Begin by inspecting the edges of the countertop for any chips or rough spots. Use a fine-grit diamond hand pad to smooth out any imperfections.
2. Attach a 50-grit diamond polishing pad to a hand polishing machine. Wet the edge of the countertop with water.
3. Start polishing the edge by moving the machine in a circular motion, applying even pressure. Continue polishing until the surface becomes smooth and even. Keep the pad wet during the process by periodically spraying water.
4. Switch to a 100-grit diamond polishing pad and repeat the circular motion on the edge. This will help refine the surface and remove any remaining roughness.
5. Progressively move to higher grit diamond pads, such as 200, 400, 800, and so on, repeating the same circular motion on the edge. Each subsequent pad will further refine the surface and bring out a glossy shine.
6. Once you reach a desired level of shine with the highest grit pad, you can use a polishing compound specifically designed for granite countertops. Apply a small amount of the compound onto a white cloth and buff the edge in a circular motion to achieve a final polished look.
7. After completing the polishing process, wipe down the countertop edges with a clean, damp cloth to remove any residue or excess polishing compound.
Remember to always wear safety goggles and follow manufacturer instructions when using power tools and diamond polishing pads. Its also advisable to practice on a small, inconspicuous area or scrap piece of granite before working on the actual countertop edges.
