What to Do About Quartz Countertop Heat Damage & How to Avoid It

Up to 185 degrees Fahrenheit are used to cure the resins and crushed quartz during the production of quartz. Quartz countertops are resistant to abrasion, staining, and impact because of the creation process.

Your quartz countertop will be able to endure 302 degrees Fahrenheit after fabrication and installation, which is much greater than what most natural stone counters can. This does not, however, imply that you should heat your engineered quartz countertop. You do not want heat damage to your quartz countertop since it will make it look flat. Learn more by reading on.

Quartz Countertop Heat Damage and Chemical Reactions

Quartz countertops cannot often be heated to a temperature high enough to ignite a chemical reaction. High heat is required to modify the chemical state of the resin binders.

This does not imply, however, that if you continually heat your countertop, a chemical reaction won’t take place. The heat will sear the countertop’s surface even if it doesn’t harm the connection holding the resin binders and crushed natural stone together.

If exposed to heat, your quartz countertop will lose its attractive appearance, even if you won’t require heat damage repair any time soon. Extreme heat may prevent a chemical reaction from happening that might otherwise change the structure of your countertops.

For example, even if a hot iron is roughly 410 degrees Fahrenheit hot, placing it on your countertop will not result in any reaction.

There might not be a response if it just occurs once or twice. However, prolonged exposure to this heat may discolor your countertop. Even then, you shouldn’t take the chance of setting any hot object on your countertop’s surface.

Curling irons don’t get as hot as cast-iron pans. The pan can heat up to 572 degrees Fahrenheit right out of the oven. This temperature is too high for the pan and can quickly lead to discoloration. The majority of pizzerias steer clear of quartz surfaces because the pies are removed from the brick ovens at temperatures as high as 698 degrees Fahrenheit.

How Does Heat Damage Quartz Countertops?

On a quartz countertop, scorch marks are the first signs of heat damage. The yellow or brown scorch marks on the resin are a sign that it has burned.

When left in the same position on the countertop repeatedly, even moderately hot pans and pots will leave scorching scars. Even for a short period of time, leaving hot objects on your counter may cause scorch marks to appear.

How to Prevent Heat Damage to Quartz Countertops

Cleaning up spills is only one aspect of maintaining your quartz countertop; you also need to protect it from damage from intense heat.

Here are some quick tips to keep your quartz in good condition. On Caesarstone, you may learn more about how to maintain your quartz countertops.

Use Trivets and Hot Pads

Utilizing counter protectors like trivets and hot pads is the simplest method to keep them safe. So that you may set your pots from the cooker, these protectants should be positioned close to your stove and the island area.

Until they are cold enough to be put on your quartz countertop, you may also keep your pots and pans on top of the stove. When using curling irons and hair dryers, utilize insulating materials if your bathroom has quartz worktops.

Protect from the Sun

While the heat from the sun is not nearly enough to harm your countertop surface immediately, it can still damage the surface with prolonged exposure.

Your quartz countertop’s hues become dulled by the heat from the sun. You won’t notice the difference if only a portion of your countertop is exposed to the light over time since that side will get duller than the other side. Curtains can be used to protect the countertop’s surface. Position the countertops so they won’t be exposed to the scorching sun when upgrading your home.

Quartz Countertop Heat Damage Repair

You need to figure out a technique to get rid of or hide scorch marks if your quartz countertop currently has them. Scratching can be done by thoroughly washing the surface with soap and water. Apply a moderate abrasive to the surface and gently scrape it. The burn scars should be scrubbed away lightly if they are not too deep.

Apply white toothpaste or a paste made of baking soda and water to the burn scars if they are still visible, and let it set for a few minutes. To get rid of the stains, softly clean the area after wiping off the toothpaste.

You must hide any severe burn marks that are impossible to remove. You may hide them by using the charred area as your new workspace and covering them with a cutting board indefinitely.

Additionally, you may cover them with a tile that is affixed to the area where hot pans and pots can be set down. As an alternative, you might utilise decorations that are glued to the countertop’s surface.


Durability is promised with quartz countertops. Since quartz natural stone constitutes the majority of these counters, you will benefit from a robust surface that withstands heat, abrasion, and scratches.

However, the surface of your counter will become damaged at temperatures exceeding 300 degrees Fahrenheit. Your countertop’s surface might become scorched by even lower temperatures if it is left out for a long period.

Quartz countertops, however, may keep their sheen for many years with proper care. Deep burn markings are difficult to erase, while surface-level scorch marks are simple to remove. You may also use Quartz Worktops to enhance the beauty of your interior.
