How to Seal My Quartz Countertop

Why Seal Quartz Countertops

There are a few key reasons why sealing quartz counters is recommended:

  • Prevents stains – Quartz is non-porous, but sealing provides an extra layer of protection against foods, oils and other potential stains. This makes cleaning easier.
  • Reduces appearance of scratches – While quartz resists scratches, sealing minimizes visibility of minor scratches over time.
  • Retains glossy finish – Sealing fills in micro-abrasions and keeps the surface looking shiny and new.
  • Prolongs life of countertop – Sealing protects against damage from spills and abrasion, helping your countertop last longer.

What You Need to Seal Quartz

Sealing quartz countertops requires just a few simple supplies:

  • Quartz countertop sealer – Select a high-quality sealer specifically designed for quartz. Avoid cheap generics.
  • Microfiber cloths – Use soft cloths that won’t leave lint behind.
  • Rubbing alcohol – This removes debris and oils prior to sealing.
  • Paintbrush – For applying sealer around edges and seams.
  • Plastic wrap – Covers freshly sealed areas while curing.
  • Blue painter’s tape – Protects cabinets and walls from drips.

How to Seal Quartz Countertops

Sealing quartz counters involves careful preparation and application of the sealer. Follow these step-by-step instructions:

1. Clean the Surface

Thoroughly clean quartz with a non-abrasive cleaner or rubbing alcohol. This removes any dirt, debris, oils, soap scum etc. that could repel the sealer. Pay extra attention to corners and seams. Let the surface dry completely.

2. Tape Off Areas

Use painter’s tape to cover cabinets, walls, and any areas you don’t want the sealer dripping on. Taping takes a little time but avoids cleanup hassles later.

3. Apply Sealer

Pour a small amount of quartz sealer onto the countertop surface. Use a clean microfiber cloth to spread the sealer evenly across the quartz. Work in sections using circular motions. Apply a thin uniform coating and avoid pooling excess sealer.

4. Seal Edges and Seams

Use a small foam brush to carefully apply sealer along all quartz edges, seams, crevices and hard-to-reach areas. This ensures full protection.

5. Remove Excess Sealer

After 5-10 minutes, gently wipe the entire surface with a clean microfiber cloth to remove any excess sealer. Going with the grain avoids streaks. All haze should disappear as sealer cures.

6. Allow Proper Cure Time

It’s critical to allow the sealer full cure time before use. This is usually at least 12-24 hours. Prevent use of the counters during this period and keep kids and pets away.

7. Remove Tape and Wipe Down

Once fully cured, carefully remove all painter’s tape from cabinets, walls and edges. Use rubbing alcohol to remove any adhesive residue. Give the counters one final wipe down.

8. Reapply Annually

For ongoing protection, quartz counters should be resealed once per year on average. Use the same cleaning and application process.

Quartz Sealing Tips and Precautions

Follow these handy tips for great sealing results:

  • Always read and follow the sealer manufacturer’s directions for best results.
  • Make sure the room is well-ventilated during sealing to allow proper curing.
  • Avoid applying sealer in direct sunlight or extreme heat which can cause excess evaporation.
  • Don’t use a steam cleaner for several weeks after sealing quartz counters.
  • Prevent use of countertops for full cure period to avoid damage.
  • Store leftover sealer properly in a cool, dry location away from kids.

Sealing adds an extra layer of stain and scratch protection for quartz countertops. With the right supplies and techniques, it can be completed by most homeowners in an afternoon. Be sure to allow full curing before resuming normal use of your counters. Reapply sealer annually for optimal, long-lasting results.

Frequently Asked Questions About Sealing Quartz Countertops

Should I seal new quartz counters?

Yes, it’s recommended to seal new quartz counters, including recently installed ones in your home. Sealing gives added protection right away before exposure to daily use.

How long does quartz sealer last?

On average, a quartz sealer application lasts around 1 year before needing reapplication. Higher quality sealers may last slightly longer.

Can I use a granite sealer on quartz?

It’s best to use a sealer specifically formulated for quartz rather than a granite sealer. Quartz requires a sealant with a weaker concentration to avoid an overly glossy finish.

What happens if I don’t seal my quartz counters?

Unsealed quartz will be more prone to staining, etching and scratching over time. Sealing is not mandatory but highly recommended to maintain the optimal look and durability.

Should I seal polished or honed quartz?

Both polished and honed quartz finishes benefit from sealing. Honed quartz is more porous and can absorb stains without a sealant. Sealing keeps both finishes looking their best.

How can I tell when quartz counters need resealing?

Signs that quartz counters need resealing include increased staining, food and liquids absorbing rather than beading up, and a loss of the glossy appearance.

Is there a non-toxic quartz sealer?

Yes, you can find quartz sealers made from natural ingredients that are non-toxic and safe once cured. Look for options clearly labeled as non-toxic.

Sealing quartz counters is a relatively simple process that provides big benefits. With proper application and regular resealing, you can keep your quartz counters in tip-top shape for many years. Be sure to use a high quality sealer made specifically for quartz and allow full curing time. Follow these best practices for stunning, protected quartz countertops.
