Quartz countertops are an increasingly popular option for home kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can become damaged over time. This leads many homeowners to wonder: can you sand quartz countertops?

The short answer is yes, quartz countertops can be sanded. However, there are some important factors to consider before taking sandpaper to your quartz. In this complete guide, we will cover everything you need to know about sanding quartz countertops, including:

What is Quartz?

Before we dive into sanding, let’s take a quick look at what quartz countertops actually are.

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz makes up about 90% of the material, while polymers act as the binding agent.

This combination creates a very hard, non-porous surface that is resistant to scratches, stains, and heat. Unlike natural stone, quartz has consistent coloring and patterning throughout.

Quartz offers a wider variety of colors and styles than natural stone. The resins allow quartz to mimic the look of materials like granite, marble, and concrete. This versatility and durability is why quartz has become a go-to countertop choice.

The Benefits of Sanding Quartz Countertops

Sanding is the process of smoothing and polishing a surface using abrasive paper or materials. When it comes to quartz countertops, there are a few reasons you may want to sand:

Removing superficial scratches – Quartz is very scratch-resistant, but not scratch-proof. Over time, daily use can leave minor scuffs and scratches. Light sanding can buff these out.
Dull, etched areas – While quartz resists stains, acidic substances like lemon juice or wine can etch the surface over time, leaving dull spots. Sanding can restore the polish.
Water spots or rings – Heat and moisture can sometimes cause spots or rings on quartz. Light sanding helps remove them.
Renewing the sheen – Periodic sanding can bring back the original glossy finish of quartz. This is especially useful for kitchens after years of use.
Preparing for re-sealing – Sanding cleans and opens the pores before reapplying a sealant.

With proper methods, sanding provides a simple way to keep quartz counters looking like new with minimal effort.

Factors to Consider Before Sanding Quartz

While sanding quartz is possible, there are some important factors to keep in mind:

Sanding is Surface-Level Only

Sanding can only remove very fine, superficial blemishes in the surface. Any chips, cracks, or deeper damage cannot be sanded out of quartz.

Color and Pattern May Be Affected

The pigments and resins that give each slab of quartz its color and veining pattern are only on the very top layer. Sanding too aggressively can cut through this top layer and expose a different shade underneath.

Sanding Produces Dust

The process of sanding quartz will generate fine dust that needs to be cleaned up carefully. Proper precautions should be taken to contain and dispose of the dust safely after sanding.

Results Require Patience

Only very light sanding is recommended for quartz. The material is too hard to sand down aggressively. Removing etches or scratches takes gradual, careful effort.

Consider Hiring a Professional

An experienced professional will have the proper tools and expertise to sand quartz countertops smoothly and evenly without risk of damage.

Step-by-Step Guide to Sanding Quartz Countertops

If you decide to DIY it, here is a step-by-step guide to properly sanding quartz countertops:

1. Clean and Prepare the Surface

Make sure the countertop is clear of any items, appliances, or fittings. Thoroughly clean the quartz and allow it to dry completely. Cover and seal any areas you do not want to sand, like backsplashes.

2. Start with Fine Grit Paper

Begin with a low abrasive grit no rougher than 200. Quartz does not require heavy sanding. Using anything coarser can cut too deeply into the surface.

3. Hand Sand in Small Circular Motions

Gently hand sand only the affected areas using small circular motions. Applying too much pressure can damage quartz. Let the sandpaper do the work.

4. Vacuum Between Grits

Once the surface is smoothed, carefully vacuum up all dust before moving to a finer grit. Lingering particles can cause scratching.

5. Work Up Through Finer Grits

Progress through finer grits like 400, 800, and 2000. High polish options like 3000-5000 can be used to restore a mirror-like sheen.

6. Rinse and Dry Completely

When satisfied with the smoothness, rinse the surface thoroughly. Allow the quartz to dry fully before sealing or waxing.

7. Seal and Polish

Apply a penetrating quartz-specific sealant to protect the countertop. Finish by buffing in a polish to maximize shine.

Helpful Sanding Tips for Quartz

Follow these pointers to get the best, safest results:

Work in small, manageable sections so dust does not accumulate.
Rinse sandpaper frequently to prevent clogging and scratching.
Use a hand sanding block rather than just paper to apply even pressure.
Always sand in the direction of the existing polish lines for a uniform finish.
Limit sanding time to avoid overdoing it. Pause frequently to check progress.
Apply sealant and wax carefully to avoid pooling in sanded areas.
Consider sanding quartz once yearly to maintain the surface and finish.

Alternative Options Beyond Sanding

In some cases, sanding may not be the best solution:

For significant damage or alterations, consult a professional fabricator/installer for advice.
Micro-abrasion tools use a precision nozzle to target etching without sanding.
Chemical cleaners designed for quartz can lift some marks without abrasion.
Strictly topical stains may be removed with hydrogen peroxide, bleach, or ammonia.
Minor scratches can sometimes be carefully buffed out with 0000 steel wool.
Replace severely damaged sections rather than sanding the entire surface.
