Frequently Asked Questions About Polishing Quartz Countertop Edges
What grit sandpaper should I use for polishing quartz?
Start with a coarse 60-80 grit sandpaper to remove heavy scratches. Then use medium 120-150 grit to smooth it out. Finish with a fine 220+ grit sandpaper to create a uniform surface for polishing.
Can I use a handheld sander instead of sandpaper?
Yes, you can use an orbital hand sander for efficiency. Just be sure to keep it moving constantly to avoid uneven sanding. Use the same grit progression.
How long does the polishing process take?
It takes 2-4 hours typically depending on the amount of countertop area. Work in manageable sections for best results. Take your time as rushing can ruin the polish.
What is the best polish to use on quartz?
Look for polish creams designed specifically for quartz. Brands like Gel-Gloss and Hope’s Perfect Countertop make excellent polishes. Avoid wax-based polishes.
How often should I polish my quartz countertops?
With proper daily care, quartz only needs polishing every 2-3 years. Polishing restores the smooth surface and removes etch marks that develop over time from use.
Can I polish just one section of countertop?
It’s best to polish and buff the entire countertop edge to ensure an even finish. Spot polishing a section will make it look different than the surrounding areas.
What causes quartz countertop edges to lose their polish?
Over time, use of the countertops causes small scratches and dullness. Quartz is very hard, but not completely impervious to etching from knives, pots, etc. Proper cleaning can prolong the original polish.
Can I polish the flat surface of my quartz countertops?
It’s not recommended. The polished finish is only on the edges. Sanding or polishing the flat surface can actually damage it.
Polishing quartz countertop edges is a straightforward process but requires time and care. By following the proper grit sandpaper progression and using a buffing pad with polish, you can restore the sleek factory finish. Just be sure to work in sections, vacuum regularly, and take the needed safety precautions. With some elbow grease, your quartz edges will shine like new again.
