What Causes Damage to Quartz?

Quartz is very resilient, but it can become scratched, chipped or stained under certain circumstances:

Cutting directly on the countertop can cause scratches and dulling over time.
Dropping heavy objects like pots, pans or appliances can chip or crack the surface.
Spills, if not wiped up quickly, can stain the quartz. Common culprits include wine, oil, and strong chemicals.
Excessive heat can damage the resin that binds the quartz particles together.

Can All Quartz Damage Be Repaired?

Minor damage like superficial scratches, small chips, and some stains can usually be repaired. However, extensive damage like large cracks or fractures may require a professional replacement. Here are some guidelines:

Scratches – Light scratches can often be buffed out through polishing. Deeper ones may need to be filled.
Chips – Small chips under 1 inch can be repaired. Larger or numerous chips likely mean replacing the tops.
Stains – Stains contained to the surface can sometimes be sanded out. But deep-set stains often can’t be removed.
Cracks – Small hairline cracks can be filled, but large fractures are beyond repair.

So while not all damage can be fixed, quartz is quite repairable compared to materials like granite or marble.

Repairing Common Quartz Damage

Here are some steps for repairing the most common quartz damages:

Fixing Scratches

Clean the area thoroughly and let dry.
Use incremental grit sandpaper to buff out the scratch. Start with something like 220 grit and work up to at least 400.
Finish by polishing with a quartz polish compound or cleaning powder on a soft cloth.

Filling Small Chips

Make sure the chip is clean and dry. Remove any loose pieces.
Mix color-matched epoxy filler per manufacturer instructions.
Fill the chip just above the surface level.
Once dry, sand flush with the surrounding countertop.
Buff to blend and polish.

Removing Stains

Try cleaning the stain with a quartz cleaner first.
If it remains, gently sand with fine grit paper. Start with something like 220.
Work up to at least 400 grit until stain disappears.
Rinse well and let dry.
Re-polish if needed.

Fixing Hairline Cracks

Clean out any debris from the crack using compressed air.
Mix small amounts of color-matched epoxy.
Fill the crack fully from the bottom up.
Wipe away excess before drying.
Once dry, buff to smooth and blend.

When to Call a Professional

While DIY repairs are possible for many quartz damages, it’s best to call in a pro for the following:

Multiple repairs needed on one countertop.
Chips larger than 1 inch.
Deep scratches that require extensive sanding.
Major cracks or fractures.
Matching the color proves too difficult.
You don’t feel comfortable undertaking the repair.

Hiring a professional ensures proper color-matching, tools, and techniques to give the best results.

Maintaining Your Quartz Countertops

To avoid future repairs:

Use cutting boards, trivets and hot pads.
Clean spills quickly, especially oils, wines, and chemicals.
Avoid exposing quartz to very high heat.
Have your countertops resealed every 1-2 years.
Handle heavy objects carefully around the tops.

With proper care and prompt repairs when needed, quartz countertops can stay beautiful for many years. Knowing that many common damages can be fixed is one of the great advantages of quartz over other natural stone surfaces.
