How to Get Scratch Out of Quartz Countertop

Quartz countertops are popular in many homes due to their stylish appearance and durability. However, like any surface, quartz can get scratched and damaged over time. Thankfully, there are several effective methods for repairing light scratches in quartz. With a little effort, you can make those annoying marks disappear.

Understanding the Composition of Quartz

Before diving into scratch repair, it’s helpful to understand what quartz countertops are made of. Quartz is an engineered stone, made from roughly 90% natural quartz mineral blended with polymer resins and pigments. The resins bind the quartz particles together to form a hard, non-porous surface.

The resins make quartz more flexible and heat-resistant compared to natural stone. But quartz is still prone to damage from sharp objects, drops, and excessive force. The material is not indestructible, so scratches and nicks are inevitable in high-use areas. The good news is that light surface scratches can be minimized with some simple DIY techniques.

Cleaning and Inspecting the Scratch

First, thoroughly clean the countertop area with a non-abrasive quartz cleaner or mild soap and water. Remove any dirt or debris to get a better look at the scratch. Carefully inspect the length, depth, and severity of the mark.

Light surface scratches are fairly easy to treat yourself. But deep gouges, chips, or extensive damage may require professional help from a fabricator. If the scratch is superficial and does not catch your fingernail, you can likely tackle it yourself.

Sanding Light Quartz Scratches

One of the most effective DIY methods is to gently sand out light scratches. You’ll need a few supplies:

  • Medium grit (400-600) sandpaper
  • Handheld sanding block or electric sander
  • Soft cloth
  • Water
  • Quartz polishing compound or automotive buffing compound

Here are the basic steps:

  1. Lightly wet the scratched area with water. This prevents friction and heat buildup from sanding.
  2. Gently rub the sandpaper back and forth over the scratch using a sanding block or electric sander on low speed. Apply minimal pressure as you smooth the area in the direction of the countertop pattern.
  3. Check often to see if the scratch is disappearing. Take care not to over-sand, as you don’t want to create any low spots.
  4. When the scratch is no longer visible, wipe away all sanding residue with a soft damp cloth.
  5. Apply a dollop of quartz polishing compound to the sanded area and buff with a soft cloth until it restores the original shine.

With some patience, this should make light scratches vanish. Be sure to buff and re-seal the entire countertop to blend the repaired section.

Filling Superficial Scratches

For very fine hairline scratches, a high-quality automotive scratch repair compound can help fill and mask the marks. Products like Meguiar’s Ultimate Compound contain micro-abrasives and polymers designed to fill in flaws and restore gloss.

Follow the product instructions to rub a small amount over scratches using a damp applicator pad or cloth. Work in circular motions before wiping clean. Repeat if needed until satisfied with the improvement.

Using Clear Epoxy Filler

For slightly deeper scratches that remain visible after sanding, a clear epoxy adhesive filler can be applied to level the surface. Products like Loctite Clear Epoxy Bonding Putty or J-B Weld ClearWeld are ideal for quartz repairs.

Follow all safety directions and mix a very small amount of the two-part epoxy. Use a plastic putty knife to carefully press the putty into the scratch, leaving it slightly higher than the surrounding countertop. Allow it to fully cure overnight. Once hardened, very gently sand flush with the quartz and then polish until smooth.

When done properly, the epoxy will be invisible but will prevent your fingernail from catching on the scratch. Take care not to overfill, or it will be hard to sand flush.

Disguising Scratches with Markers

For superficial scratches that do not catch a fingernail, concealing markers can provide a quick fix. Use a white wax crayon or gray touch-up marker formulated for quartz and granite. Lightly color along the scratch and wipe off any excess.

This won’t fix the damage but it cleverly disguises it by blending with the countertop pattern. However, markers are not a permanent solution, so the color may require occasional re-application.

Preventing Future Damage

To avoid a recurring cycle of scratches, take steps to protect your quartz surface:

  • Use cutting boards and hot pads rather than cutting directly on the quartz.
  • Apply silicone trivets under hot pans or appliances that may scorch.
  • Don’t allow harsh cleaners or solvents to contact the countertop.
  • Clean spills promptly to avoid stains setting.
  • Install a sink mat or protective grid if the sink and faucet are integrated with the quartz.
  • Avoid abrasive scouring pads and powders that can dull the finish.
  • Apply a penetrating quartz sealer every 1-2 years for added protection.

With proper care and early treatment, you can keep your quartz looking smooth and pristine for many years. Don’t ignore scratches – address them promptly and your countertops will continue shining.

Frequently Asked Questions

What’s the easiest way to remove a light scratch from quartz?

Gently sanding with medium grit sandpaper is the easiest DIY method for removing light surface scratches from quartz countertops. Combine sanding with a polishing compound to restore the original luster.

Can all scratches be removed from quartz?

Minor superficial scratches can be minimized or removed with the right techniques. But deep gouges, chips, or extensive damage may be impossible to eliminate completely without professional help.

What tools do I need to sand out light quartz scratches?

You’ll need medium 400-600 grit sandpaper, a hand sanding block or power sander, water, microfiber cloths, and a quartz polishing compound. Optional extras are automotive scratch remover and clear epoxy filler.

Is there a homemade remedy for fixing quartz scratches?

Baking soda mixed with water to form a paste can gently smooth and polish superficial scratches. Use a soft cloth and minimal pressure for best results. But sanding and commercial compounds work better for deeper marks.

Should I use a quartz scratch removal kit?

Many companies sell all-in-one scratch repair kits for DIY use. These contain sandpaper, polishing pads, and compounds tailored for quartz. When used properly, these kits can effectively improve scratches. Just follow the instructions carefully.

Can I use automotive buffing compound on quartz?

Yes, high-quality automotive polishing compounds are safe and effective on quartz countertops. Products like Meguiar’s Ultimate Compound help fill and level light scratches and restore the finish. Avoid aggressive cutting compounds.

Is there a homemade scratch filler I can use on quartz?

Clear nail polish or super glue can temporarily fill very fine scratches in a pinch. But for best results, use a commercial clear epoxy adhesive made for stone repairs. Homemade fillers likely won’t match the quartz color or durability.

How can I prevent future scratches on my quartz countertops?

Prevent scratches by using cutting boards, trivets and hot pads, avoiding harsh cleaners that can etch quartz, cleaning spills quickly, installing sink mats, and applying an occasional sealing treatment.

Can quartz fabricators remove deep scratches from an installed countertop?

For severe damage like deep gouges and chips, full replacement may be needed. But in some cases, fabricators can sand down and re-polish areas of installed quartz to effectively remove major scratches.
