How Often to Seal Quartz Countertops

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, no surface is impervious to damage, so proper sealing is essential for longevity. Here is a complete guide on how often to seal quartz countertops.

What is a Quartz Countertop?

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals blended with resins and pigments. This combination creates a durable, non-porous surface that is resistant to scratches, stains, and heat.

Unlike natural stone countertops like granite or marble, quartz does not need to be sealed regularly since it is non-porous. However, sealing is still recommended to enhance stain protection and make cleaning easier.

Benefits of Sealing Quartz Countertops

  • Strengthens stain resistance – Sealant forms a protective barrier that prevents stains from penetrating the surface.
  • Smoothens the surface – Fills in micro pores and creates an even, smooth finish.
  • Makes cleaning easier – Spills and messes wipe off easily from a sealed surface.
  • Enhances shine – Leaves a glossy, like-new appearance.
  • Prolongs lifespan – Protects against damage from spills, abrasions, and daily wear and tear.

How Often Should You Seal Quartz Countertops?

Quartz countertops should be sealed every 1 to 2 years on average. More frequent sealing may be needed in busy kitchens or bathrooms. Here are some factors to consider:

1. Traffic and Usage

High traffic areas may need more frequent sealing. If your counters see heavy daily use, seal yearly. For lightly used surfaces in guest baths or bar areas, every 2-3 years is sufficient.

2. Exposure to Moisture

Since liquids cannot penetrate properly sealed quartz, frequent sealing is key around sinks and dishwashers where water exposure is high. Reapply sealant every 1-2 years in these locations.

3. Cleaning Habits

Counters cleaned frequently with abrasive pads or harsh cleaners wear down the sealant quicker. Be sure to use non-abrasive pads and mild cleaners. You may need to seal more often if you use abrasive methods.

4. Location

Kitchen counters need more frequent sealing than bathroom vanities which aren’t exposed to as many spills. Prioritize sealing kitchens first, then bathrooms and other areas.

5. Finish and Color

Darker quartz finishes often show signs of wear sooner than lighter colors. Reseal dark countertops every 1-2 years and lighter ones every 2-3 years. Highly polished finishes may need more frequent sealing too.

How to Tell if Your Quartz Countertops Need Resealing

Here are signs that indicate your quartz counters are due for a refresh:

  • Water beads do not form when you splash the surface with water.
  • Spills and liquids soak in instead of beading up.
  • There is noticeable etching, pitting, or wearing of the surface.
  • Counter has a chalky, dull appearance rather than a glossy shine.
  • You notice stains setting in even after cleaning.
  • Food and liquids leave behind a residue.
  • Surface feels rough or uneven instead of smooth.

Any of these are cues that it is time to reapply sealant. Address these issues as soon as possible to avoid permanent damage.

What Sealant Should You Use?

Select a sealant formulated specifically for quartz:

  • Look for water-based silicone or acrylic sealers. Solvent-based sealers can damage quartz.
  • Pick a non-toxic, food-safe formula if sealing kitchen counters.
  • Match the finish – matte for honed quartz, semi-gloss or glossy for polished finishes.
  • Get a reputable brand designed for stone and quartz. Hardware stores carry quality options.

Avoid generic sealers for marble, granite, etc. as they may interact poorly with quartz resins. Always check label directions too.

How to Seal Quartz Countertops

Sealing quartz countertops is a simple DIY project. Follow these key steps:

Step 1: Clean the Surface

Use a non-abrasive cleaner and soft cloth or sponge to remove all debris, residues, dust, and dirt. Rinse and dry completely.

Step 2: Read Sealant Instructions

Read the product label fully and follow application directions. Check what PPE gear to wear and ensure proper ventilation.

Step 3: Apply Sealant

Use a clean paintbrush, lint-free cloth, or foam applicator. Apply a thin, even layer and spread out any excess puddling. Read drying times.

Step 4: Allow Proper Curing Time

Most sealers take 12-24 hours to fully cure. Avoid counter use during this period. Turn on vents and fans to improve air circulation.

Step 5: Remove Excess Residue

Gently buff off any visible haze or film with a soft cloth once fully cured. Resealing is now complete.

Step 6: Regular Cleaning

Maintain the sealant by using mild, non-abrasive cleaners only. Avoid harsh chemicals or scrubbing pads.

Being diligent about sealing maintenance preserves your investment in beautiful quartz counters for years of use. Reapply sealant every 1-2 years as a best practice. Address any signs of damage right away to retain a flawless, factory-fresh look. With proper care, quartz countertops will withstand decades of wear while retaining their like-new beauty.

Frequently Asked Questions

How long does sealant last on quartz?

On average, sealant will last 1 to 2 years on quartz before needing reapplication. Factors like usage, exposure, and maintenance impact longevity. Reapply whenever signs of wear appear.

Can I use wax instead of sealant?

Wax is not recommended as it builds up over time and is harder to remove. It can also cause hazy residue. Use a purpose-made quartz sealant for best protection.

Should sealing be done by a professional?

Quartz sealing is a simple do-it-yourself project. Homeowners can easily perform this basic maintenance task. Hire a pro for extensive repairs only.

How soon can I use the counters after sealing?

Avoid counter use for 12-24 hours after sealing to allow the protective layer to fully cure. After that, your quartz is ready for regular use.

What’s the cost to seal a quartz kitchen counter?

The cost depends on the size of your counters, but high-quality sealants average $10-$30. Total cost is low since DIY application is quick and easy. Resealing every few years maintains their beauty.


While durable, quartz counters benefit from periodic resealing every 1-2 years on average to look their best. More frequent application is needed in heavy use areas. Resealing enhances stain resistance, smoothens the surface, simplifies cleaning, and preserves the flawless factory finish. With proper sealing maintenance, quartz countertops will stay looking like new for decades. Be sure to reapply sealant as soon as you notice any signs of wearing or damage on your quartz. Consistent resealing ensures your investment retains its beauty while withstanding years of use.
