Quartz counter tops are known for their beauty. Quartz comes in a variety of colours 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.
Place cooling pads or pot holders under hot items being placed on the counter. Also, avoid sliding metal items across the counter to help avoid scratches in the future.
Do not use the counter top as a cutting surface. This can damage the surface. The Kitchen Countertops website states, "Avoiding bleach is a key factor when it comes to maintaining your quartz countertop in a perfect condition."
