The natural color variations and strength of granite make the stone an ideal support for many household applications, including countertops. When properly installed and finished, the stone resists staining and damage. Over time, however, heat, chemicals and regular wear and tear etches the stone surface, leaving scratches, cracks or unsightly discoloration. While replacing the granite is one option, you can also change its appearance by resurfacing the stone with laminate color. Laminate will change the look of the granite for the appearance of a new countertop.
Remove the countertop from its supports on the cabinets or platform beneath. Depending on the installation, this will involve removing screws or bolts from below or applying acetone or a heat gun to dissolve glue. Remove all attachments and take the granite countertop to your workspace. Because granite is a heavy stone, you will need help carrying the granite to your workspace.
Wipe down the granite countertop surface with a damp rag to remove surface dirt and dust.
Ventilate your work area by opening windows or activating exhaust fans. Wear rubber gloves and protective goggles when working with chemicals.
Clean the granite surface with a rag dampened in a chemical stripper containing methylene chloride. This powerful chemical will remove old sealant from the granite countertop, creating a clean surface to which the laminate will bond. If necessary, scrape away loosened sealant with a plastic scraper.
Sand the granite surface lightly with medium-grit sandpaper, followed by fine-grit sandpaper. This will make the granite more likely to adhere strongly to the laminate.
Use a paintbrush to apply an even coat of laminate glue over the surface, including the edges. Cover the entire countertop with a thin layer; do not allow some spots to contain more glue than others -- this will create an uneven appearance to the laminate.
Start at one end of the countertop and lay your laminate sheets onto the glue. Fold the sheets as necessary to cover the edges of the countertop. Set the pieces in place and them roll them with a roller to push out any air or excess glue from under the laminate.
Clean any excess glue that leaks out with a damp sponge or a rag dampened with acetone. Allow the glue to dry for at least 48 hours before returning your resurfaced countertop to the kitchen.
