How to Remove Watermark from Quartz Countertop


Quartz countertops are a popular choice for kitchen and bathroom remodeling projects because of their durability, low maintenance, and stylish appearance. However, some quartz slabs come with a manufacturer’s watermark etched into the surface. This watermark acts as a trademark but can be an eyesore in your home. Thankfully, there are a few methods to remove or minimize the visibility of a quartz countertop watermark.

What Causes Watermarks on Quartz?

Quartz countertop slabs are made from ground quartz particles combined with resins and pigments. The manufacturer stamps or etches a logo or name into the surface while it is still soft, leaving behind a permanent watermark. This marking allows manufacturers to identify their product.

Watermarks range in depth depending on the method used to mark the quartz. Some are faint etchings that become nearly invisible once the countertop is installed. Deeper watermarks are more conspicuous and harder to remove.

Should You Remove the Watermark?

Most watermarks blend into the overall look of the countertop and do not detract from its appearance. Etching or grinding too aggressively to remove them can damage the quartz and void the manufacturer’s warranty.

However, if the watermark bothers you aesthetically, there are safe ways to minimize its visibility. Completely removing a deep watermark requires replacing the slab.

Methods to Remove or Reduce Watermark Visibility


Gently sanding the watermark with progressively finer grit sandpaper can reduce its prominence. Begin with 220 grit and work up to at least 400 grit, following the direction of the etching. Avoid applying too much pressure, which can scratch the quartz and make the mark more obvious. Be patient, since this method takes time.


Using an etching cream designed for quartz, carefully apply it over the watermark following the manufacturer’s instructions. This chemically removes a thin top layer of the quartz to reduce the depth of the marking. It may take several applications to noticeably minimize the watermark.


Use a quartz polishing compound and a microfiber cloth to buff out the watermark. Apply the compound and rub it into the affected area using firm, circular motions. The friction helps smooth and blend the mark into the surrounding quartz. For best results, follow up with a quartz sealant.


As a last resort, you can mask the watermark using specialty paints made for quartz. This involves meticulously painting over just the watermarked portion while avoiding getting paint on the rest of the countertop. The finish may not perfectly match the quartz, and the paint can chip or fade over time.

Preventing Damage While Removing Watermarks

  • Work slowly and cautiously to avoid accidentally damaging the quartz.
  • Try removal methods in inconspicuous areas first to test results.
  • Follow all product instructions carefully and use proper tools.
  • Avoid abrasives like steel wool that could scratch the surface.
  • Check with your countertop provider before attempting to remove a watermark.
  • Be prepared to live with a reduced but still faintly visible watermark.

When to Call a Professional

If you are unable to successfully minimize or remove the watermark yourself, consider hiring a professional stone restoration company. They have specialized tools and expertise to remove stubborn marks while ensuring the structural integrity of the quartz remains intact. This route is best for deep watermarks that require essentially re-polishing the surface.

Maintaining Your Quartz Countertops

Once you’ve removed or reduced the watermark, be sure to properly care for your quartz countertops to prevent future etching:

  • Use cutting boards and trivets for hot items to avoid burns.
  • Clean spills promptly with mild soap and water.
  • Avoid abrasive cleaners and pads.
  • Re-seal periodically with a quartz sealant.
  • Don’t place extremely heavy items on unsupported areas.

Frequently Asked Questions

Can I completely remove any quartz watermark myself?

It depends on the depth of the marking, but completely removing deep watermarks is difficult without professional help. You can usually minimize the appearance of fainter marks yourself.

Will sanding damage my quartz countertop?

If done gently, sanding with fine grit paper should not harm quartz. But applying too much pressure or using coarse paper could scratch the surface.

Is etching cream safe for all quartz?

Check the product instructions, as some etching creams are formulated specifically for engineered stone. Using the wrong chemical could damage certain quartz types. Test first.

How do I know if I should remove the watermark?

It comes down to a personal choice. If the mark significantly bothers you visually, try minimizing it. If not, simply leave it since it identifies the slab manufacturer.

Does a watermark affect the function of my quartz?

Not at all. A watermark does not impact the durability, strength, or performance of your quartz countertops. It is only a cosmetic concern.


Quartz manufacturer’s watermarks can detract from the clean look of countertops but are not always worth removing. Methods like sanding, etching, and polishing can help reduce the visibility of marks without damaging the integrity of the quartz. For deep watermarks, professional help may be needed. With the right tools and techniques, you can successfully minimize watermarks and enjoy beautiful, markup-free quartz countertops.
