How to Reseal Quartz Countertops

Resealing quartz countertops helps protect their beautiful finish and extends their lifespan. Quartz is an engineered stone made from natural quartz crystals blended with resins and polymers. It is nonporous, so liquids don’t penetrate the surface. However, sealing quartz provides an added layer of protection and makes the counters easier to clean and maintain. Here is a step-by-step guide on how to properly reseal your quartz countertops.

What You’ll Need

  • Quartz countertop sealant (look for a sealant specifically made for quartz)
  • Microfiber cloths
  • Rubbing alcohol
  • Painter’s tape
  • Safety gear like gloves and goggles

Step 1: Clean the Surface

Thoroughly clean your quartz countertops with a mild soap and water. Make sure to remove any residue, dirt, grease etc. Wipe the surface completely dry with a microfiber cloth.

Use rubbing alcohol and wipe down the countertops to remove any remaining oils or soap residue. Let the alcohol fully evaporate. This helps the sealant adhere properly.

Step 2: Tape off Areas

Use painter’s tape to mask off areas you don’t want to get sealant on, like the walls, backsplash, cabinets etc. Make sure to press the tape down firmly.

Step 3: Apply the Sealant

Follow the product directions for applying the sealant. Typically, you’ll apply it directly to the countertop using a microfiber cloth or foam applicator. Apply a thin, even layer and rub it in using circular motions.

Let the product soak in for 5-10 minutes. Then buff off any excess with a clean microfiber cloth. Going with the grain usually works best.

Step 4: Apply a Second Coat

For optimal protection, apply a second thin coat of sealant. Follow the same steps as before – apply a thin layer, let it soak for 5-10 minutes, then buff off any residue.

Two coats helps seal the surface fully and provides a glossy, like-new finish.

Step 5: Remove the Tape

Once the sealant is fully cured (usually 24 hours), carefully remove the painter’s tape. Be sure the sealant is completely set before removing the tape.

Step 6: Clean Up

Wash any equipment with soap and water. Properly dispose of any rags, cloths or applicators saturated with the sealant. Let cured sealant harden before scraping it off any surfaces.

And that’s it! Your quartz countertops are now resealed and look amazing. Be sure to reapply the sealant every 1-2 years for optimal results. Avoid using abrasive cleaners or placing hot items directly on the surface.
