Quartz counter tops are known for their beauty. Quartz comes in a variety of colors and patterns and is easily cut and modified to fit into any space. Quartz is also known for its resiliency against heat and cold. But even a quartz surface has its limits, and normal wear and tear such as scratches can occur. Repairing a scratched quartz counter top takes a bit of effort, but the surface can be restored to like-new condition.
Clean the counter top thoroughly, especially the damaged area. An ammonia-based cleanser, such as a window cleaner is best, or you can create your own cleaner by adding 1 cup of ammonia to 2 cups water.
Wipe the counter dry with a clean, dry cloth. Make sure the counter is completely dry and free of dirt, dust and grime.
Apply fast-acting glue to the scratched area. Make sure the glue fills the entire scratch. Allow the glue to set for a minimum of 24 hours.
Remove the excess glue from the counter top surface with a razor blade or utility knife. Hold the blade at a 45-degree angle and carefully scrape away the glue around the filled-in area.
Sand the filled-in surface with fine sandpaper until the surface is smooth. Use a damp cloth to wipe away the excess glue and grit from sanding.
