Do Quartz Countertops Need to Be Sealed? – The Most Honest Answer

Kitchens are the most phenomenal part of the house.

You can add a unique charm to your house by touching up some cabinet and worktop designs.

Quartz countertops are a popular choice for luxury kitchen designs.

Quartz worktops are smoother and require less maintenance.

Moreover, they come in a wide range of colors and are reasonably durable.

However, one common question almost every homeowner ask is, ‘does quartz countertops need to be sealed?’

Quartz countertops don’t require any sealing because they have less porosity.

Quartz has significantly less spacing between its molecules, so it resists stains without sealing than other worktop materials like granite.

Advantages Of Sealing a Quartz Countertop

Many users deem sealing quartz worktops as a waste of time and money.

However, it offers some tremendous unseen benefits.


Sealing your quartz countertop requires the tiniest budget, and the sealants are readily available.

Moreover, they are not challenging to use, so you can seal the countertop as a personal project without hiring a professional for the job.


Although quartz countertops are durable, they may flatter due to excessive heat over time.

Here sealing helps because sealants include compounds to increase the heat resistivity of the material, so it lasts long.

Also, sealing proves beneficial if you renovate a cafeteria countertop as it prevents surface scratches and spill stains.

Prevents Seeping

Seeing black coffee and tea stains on your worktops ultimately makes you wonder do you need to seal quartz countertops. 

Strong liquids leave nasty stains as they seep into the countertop, leaving a permanent mark.

The fluid penetrates the molecular space in the countertops, making it uncleanable.

However, with a sealing present, the liquid stays on the surface and can be easily cleaned.

A Valuable Investment

Quartz countertops are about 20 to 40 percent more expensive than other worktop options.

So naturally, you’ll want to ensure they don’t get chipped or cracked.

Sealing your quartz countertop is good as it ensures that it will remain unbroken longer than the unsealed ones.

Ensures Color Retention

The color of your quartz countertops may dim over time.

It may be due to regular usage, cleaning, or simply eventual wear.

However, sealing helps ensure that your quartz worktop’s bright finish remains intact for much longer.

If you plan to let go of your ‘does quartz countertops need to be sealed’ quest for the moment, that is fine.

The below tips will help you keep your quartz countertop in good shape until you decide to seal it.

Never Use Abrasive Products

Scrubbing, brushing, and other abrasive products are terminal to your gleaming quartz countertop.

Although they are resistant to nicks, the continuous abrasions will leave them scratchy over time.

 No Chemicals

Sealing your quartz countertop may be optional, but that doesn’t mean they are untouchable to all kinds of damage.

Using intensive cleaners damages the surface and shine of your countertops.

Therefore, it is essential to keep chemicals like paint removers, thinners, and over-cleaners away from them.

Avoid Excessive Heat

Heating expands all surfaces, and quartz countertops are no different.

The contraction and expansion of heating and cooling damage the internal structure causing the worktop to crack or break.

Exposing quartz countertops to intense stove heat is dangerous.

Therefore, it is best to use cooking range designs with quartz worktops.

Don’t Cut Things Directly on Them

Preventing your quartz countertops from scratches is necessary.

However, you also need to take care of the cutting jobs you do on them.

Without the sealant, the acidity from the fruits will cause the countertop to attain a dull look as it diminishes its shine.

Ensure Daily Cleaning

Although these worktops are relatively stain-resistant, everyday cleaning helps preserve their shine.

Moreover, it also ensures hygiene.

Cleaning a quartz countertop is probably the easiest thing in the world.

All you have to do is dampen a kitchen towel and wipe the worktop.

Later use a dry cloth to dry the wetness.
