What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from crushed quartz combined with resin and other materials. The quartz content typically ranges from 90-94%. Pigments are added to achieve different colors and patterns. The result is a material that is non-porous, stain resistant, and more scratch resistant than granite.
Can You Grind Down Quartz Countertops?
Yes, it is possible to grind down quartz countertops to remove scratches, etching, and other imperfections. However, there are some important factors to consider:
Grinding Removes Material
Grinding will remove a thin layer from the surface of the quartz. Depending on the severity of the damage, 1/16 to 1/8 inch may need to be removed. This permanently reduces the thickness of the countertop. Too much grinding can impact structural integrity and lead to cracks or fissures.
Surface May Not Match
The area that is ground will have a different appearance than the surrounding quartz. Even if the same color quartz is used, variations in pattern and texture can be noticeable after grinding. Seam lines around sinks or backsplashes may also be more pronounced.
Process Requires Skill
Grinding quartz countertops is a job for a professional fabricator. It requires specialized tools and experience to achieve an even, smooth finish across the entire surface. DIY grinding is likely to result in uneven spots and poor aesthetics.
Alternatives May Be Better
For minor damage like shallow scratches, alternative restoration methods like polishing or resurfacing may work better than grinding. These remove less material and have a lower risk of altering the appearance.
Professional Grinding Process
If grinding is determined to be the best solution, here is what a professional fabricator will do:
- Evaluate the damage and determine how much quartz needs to be removed.
- Mask walls, backsplashes, and other surfaces to contain dust.
- Use a hand grinder or mechanical grinding machine with progressive diamond grit pads, starting with 50 or 100 grit and gradually increasing.
- Keep the grinder constantly moving to ensure an even removal of material.
- Vacuum up dust between grit changes.
- Finish with a 3000 grit pad and polish.
- Clean and seal the surface afterwards.
- Address any issues with seam lines, edges, or changed appearance compared to the surrounding areas. This may involve altering backsplashes, sanding edges, or replacing sinks/faucets.
How to Prevent Needing to Grind Quartz
While quartz is very durable, there are steps you can take to prevent damage and avoid the need for grinding:
- Use cutting boards and hot pads to protect the surface. Never cut directly on quartz.
- Clean spills quickly, especially acidic substances like wine or fruit juice that can etch.
- Avoid using abrasive cleaners or scouring pads. Use a soft cloth with mild soap and water.
- Don’t place hot pans directly on the quartz. Always use trivets.
- Re-seal the quartz every 1-2 years with a penetrating sealer to prevent stains.
- Inspect countertops periodically for any developing scratches or cracks that need attention.
Can You Grind Down Quartz Yourself?
It is not advisable for homeowners to attempt grinding quartz themselves. The process requires specialty equipment and experience to properly assess removal depths and achieve a consistent finish. Mistakes made during DIY grinding can permanently damage the structural integrity or appearance of quartz countertops. It’s best to hire a professional fabricator experienced specifically with grinding quartz.
Conclusion
Yes, it is possible to grind down quartz countertops to renew their appearance and remove unsightly scratches or damage. However, there are downsides in terms of removing thickness, potential appearance changes, and the skill required. Preventing damage through proper care and maintenance is best. But for existing damage, consult a professional fabricator to determine if grinding, polishing, or resurfacing will get your quartz countertops looking like new again. With their expertise, they can grind the quartz successfully without compromising the structure or aesthetics around sinks, seams, and edges.
