How to protect your quartz countertops from heat damage

Watch out for that hot plate!

Heat is one of the only things that can truly damage a quartz countertop. But how hot is too hot? How long can they stand the heat? And what can you do to protect your beautiful quartz countertops?

Heat damages quartz

Engineered surfaces like quartz and FriTech™ are made up of 90% mineral and 10% resins and dyes. These resins bind the minerals together, creating a durable and stain-resistant surface. The only danger is that these resins are susceptible to heat damage. Too much heat and they can melt or burn, hurting the integrity of your quartz countertops.

How hot is too hot?

Quartz countertops can withstand heat up to about 300 degrees Fahrenheit or about 148 degrees Celsius. At this temperature, the heat will break down the resin, resulting in damage.

What things are too hot?

Dishes out of the oven, pans off the stove! Pro-tip: if it’s too hot to touch directly, it’s too hot for your countertop.

While a cup of hot tea or hot coffee doesn’t reach 300 F, we’d still consider putting down a coaster.

What type of damage can heat do to quartz?

The most common type of heat damage is discoloration. When the resins are exposed to heat, they will develop browned scorch marks. Additionally, if your quartz countertops are exposed to extreme heat, and then extreme cold, they may crack, causing irreparable damage.

How can I prevent heat damage in my quartz countertops?

Do not place hot items directly on your quartz countertops. If it’s too hot to touch, it’s too hot to place on your countertop. Place a coaster under hot mugs. Rest hot plates on trivets or an insulating material. It’s that easy! Keep the heat away, and your countertops will last for decades.
