Quartz Countertop Heat Damage and Chemical Reactions
In most homes, it is not possible to expose your quartz countertops to enough heat to cause a chemical reaction. The resin binders need high heat to change their chemical state.
However, this does not mean that a chemical reaction will not occur if you expose your countertop to heat repeatedly.
Even if the heat does not damage the bond that holds the resin binders and ground natural stone, the heat will scorch the surface of the countertop.
You may not need quartz countertop heat damage repair any time soon, but once exposed to heat, your countertop will lose its appealing appearance.
If you expose your countertops to extreme heat, a chemical reaction that alters the structure of your countertop might not occur.
If, for instance, you place a hot iron on the surface of your countertop, it will not cause any reaction even though the iron is about 410 degrees Fahrenheit hot.
If it happens once or twice, there may be no reaction. However, exposing your countertop to such heat for a long time will cause discoloration. Even then, you should not risk placing any hot item on the surface of your countertop.
A cast-iron pan gets hotter than a curling iron. Right off the oven, the pan can reach a temperature of up to 572 degrees Fahrenheit.
This temperature is too hot for the pan and can cause discoloration almost immediately. Most pizzerias avoid quartz countertops as the pies come off the brick ovens at very high temperatures, up to 698 degrees Fahrenheit.
How Does Heat Damage Quartz Countertops?
Heat damage to quartz countertop occurs immediately as scorch marks. The scorch marks, which are either yellow or brown, are an indication that the resin is burnt.
Even moderately hot pans and pots can cause scorch marks if they are constantly placed on the same spot on the countertop.
Leaving hot items on the surface of your counter even for a few minutes will make the counter develop scorch marks.

Use Trivets and Hot Pads
The easiest way to keep your countertops protected is to use protectants such as trivets and hot pads. These protectants should be placed near your stove and the island area so you can place your pots from the cooker.
You can also leave your pots and pans on top of the stove until they cool enough to be placed on your quartz countertop.
If you have installed quartz countertops in your bathroom, use insulating objects when you are using curling irons and hair dryers.
Protect from the Sun
While the heat from the sun is not nearly enough to cause significant immediate damage on the surface of your countertop, it can still cause damage after a long period of exposure.
The heat from the sun dulls the colors of your quartz countertop. If only a section of your countertop is exposed to the sun, after a while, you will not see the difference as that side becomes duller than the other side.
You can use curtains to keep the surface of your countertop protected. If you are remodeling your home, position the countertops in a way that they will not be exposed to the hot sun.
Quartz Countertop Heat Damage Repair
If your quartz countertop has already developed scorch marks, you need to find a way to remove or cover the scorch marks. You can scratch by cleaning the surface thoroughly with soap and water.
Lightly scrub the surface with a mild abrasive. If the scorch marks are not deep, they should be removed through light scrubbing.
If the scorch marks still remain, smear white toothpaste or a paste of baking soda and water on the marks and let it sit there for a few minutes. Wipe off the toothpaste and lightly scrub the surface to remove the marks.
If the scorch marks are deep and will not come off, you will need to cover them. You can cover them by making the scorched area your new working area and covering them permanently with a chopping board.
You can also cover them with a tile adhered to the surface on which you can place hot pans and pots. Alternatively, you can use decorations adhered to the surface of the countertop.
Quartz countertops promise durability. Seeing that the main component of these countertops is quartz natural stone, you will enjoy a hard surface that resists abrasion, scratches, and heat.
However, temperatures above 300 degrees Fahrenheit will damage the surface of your counter. Even lower temperatures can scorch the surface of your countertop if it is exposed for a long time.
With good care, however, quartz countertops can maintain their shine for decades. Scorch marks on the surface are easy to remove but deep scorch marks are challenging to remove.
