How to Repair Scratches on a Quartz Countertop

Quartz is a very hard and durable material. It is bested only by Corundum, Topaz, and Diamond on the hardness scale. Despite its hardness quartz countertops are still prone to scratches. This is because the quartz countertops we know are actually a compound of quartz powder and polymers, resins, and pigments. Don’t fret. The compounds are made of 97% Quarts and 7% of binders and pigments. It is the resin component of the quartz that is prone to scratching.

Depending on the extent of the damage, a lot of quartz scratch repairs can be done in the comfort of your home. It can save you a lot of money from having a professional do it.

Before you repair scratches on quartz

There are things to consider before you repair scratches on your quartz countertops. One of the first and most important is to check the terms of your warranty. Some procedures that may be part of the repair might void your warranty. Make sure to take the few minutes needed to read through your terms.

After reviewing your warranty, make sure you have a safe working area by clearing off any container or utensil from the quartz countertop. Also, take the time to clean the countertop by whipping it with a cloth damp with soapy water. You can take this as hitting two birds with one stone.

Once cleaned, assess the severity of the scratch and look for any other types of damage on the quartz countertops. If the job seems more than you can handle, seek professional help.

Next, you would want to prepare all the materials and tools needed for the job. Safety is our main priority. Make sure you have a safety goggle, working gloves, and a facemask handy. You will be handling potentially dangerous chemicals. Make sure to protect yourself.

The pieces of equipment needed for the job will be a razor blade, a speed grinder, and polishing pads. The materials you will need are quartz formulated resin or epoxy, polishing compound, and microfibre towels.

Repairing scratches on quartz countertops

There are two procedures that you can employ depending on the severity of the damage. Light scratches can usually be fixed by buffing and polishing, while deeper scratches might need to be filled with resin or epoxy. One of the ways to determine if a scratch is deep is softly running your fingernail over the surface. If it catches your fingernail, it may already be too deep to buff out.

Light Scratches

Despite the care and attention your give to your stone countertops, it may still scratch. The good news is that most light scratches caused by regular use can be buffed off. Here are some steps in ridding your quartz countertops of light scratches and restoring its brand new look.

One of the first things to secure is the type of polish to buff the scratches with. The best way to go is to look for quartz formulated buffing or polishing compounds.

You would then want to apply a half dollar size of the polishing compound on the area being repaired. Make sure you attach the buffing pad securely to the grinder. The recommended speed is at 2800 RPM. You would want to make sure that you only apply light and even pressure while buffing. Remember that your quartz countertop is partly resin. Prolonged hard and heavy buffing might actually cause the resin to melt.

Start from the lowest grade of polish, and then work your way up. Make sure that you remove any residue of the polish and replace pads before moving to a higher grade.

After completing the task, wipe off any compound on the surface, and admire your work.

Heavy scratches

Similar to buffing, make sure the area is cleared off of any items and wiped clean with soapy water. Take a few moments to assess the depth of the scratch. While you’re at it, make sure to inspect the rest of the countertop to look for other scratches you might not have noticed before.

Next, make sure the resin or epoxy filler you will be using is suited for your type of quartz countertop. The best way to do this is to check with your manufacturer. There are also colored fillers in the market. The thing is, you will need to perfectly match the color of your countertop to ensure a job well done. A mismatched filler might actually make the scratch stand out even more.

Fill the scratch with epoxy or resin and allow the filler to stand for 24 hours. Some manufacturers might require more time to set, so make sure you check. Once set, scrape off the excess so that the filled portion matches the level of the surrounding area. Use a razor blade and gently graze the surface at an approach angle of 45 degrees. Wipe off any loose material and admire your work!
