Quartz countertops are one of the most popular types of stone countertop these days. They’re durable, affordable, and come in a variety of colors and textures that offer something for everyone.
One question that many people have about this type of material is whether or not it’s porous? In this article, I will answer that question and talk about some other things you might want to know before installing quartz in your kitchen or bathroom.
But first, let’s address the elephant in the room; Is the quartz countertop porous?
Quartz countertops are NOT porous due to the presence of materials like polyresin that acts as an adhesive that holds the ground quartz stone tightly together. Also, the sealer that is applied to the surface of quartz countertops makes them non-porous.
In order for a material to be classified as porous, it must be able to absorb and retain water and other liquids.
Non-porous materials like quartz cannot do this because they have a smooth surface that is created by the manufacturing process.
Generally speaking, quartz countertops are not porous because they’re made of stone that is tightly bound together with polymer materials that make them non-porous.
In addition, the surface of quartz countertops is sealed to create a smooth and cleanable finish that prevents liquids from penetrating the surface.
What is Porosity?
Porosity is a measure of a material’s ability to be penetrated by other materials. In terms of countertops, it refers to how much water can pass through the material. If water can’t pass through the material, it’s considered non-porous and if lots of water passes through the material then you have a porous material.
Anything that is made out of stone or ceramic, including quartz countertops are not considered to be porous because they have tiny holes that are too small for water to pass through.
So always remember that when searching for natural stone countertops, you might come across the term “porosity.” The percent of open pores in the stone that allow liquid and air to pass through is known as porosity. In terms of natural stone countertop, quartz is nonporous, granite is a less porous material, whereas limestone is very porous.
Reasons Why Quartz Is Nonporous
1. Quartz Is Engineered To Be Nonporous
One of the first reasons why quartz countertops are nonporous is because the quartz material itself is engineered to be nonporous. This is because quartz is made from a combination of 90% ground natural quartz with about 10% polyresin.
These main ingredients are then mixed with pigments and polymer resins that help to bind the material together.
What this means is that quartz countertops are nonporous because they are made that way. Also, the structure of quartz is peculiar.
Quartz is crystalline in structure, and that means it’s naturally resistant to liquid absorption. This is part of the reason why quartz is such a durable material that can withstand heavy daily use.
2. Quartz Countertops Usually Has A Polished Surface
The next thing that makes quartz countertops nonporous is because the outer surface of quartz is usually polished to a shine and sealed with resin, making it extremely resistant to absorption.
The main reason why quartz countertops are nonporous is that when the surface is polished and sealed, it creates an extremely smooth layer that is resistant to penetration.
It’s not impossible for liquids or other substances to penetrate the polished surface of the quartz, but it takes a lot more effort than it would with a less polished surface.
However, if you were to break through the sealant and polish of quartz countertops, then it’s likely that the material will absorb liquids and stains.
3. The Density Of Quartz Makes It Nonporous
Quartz is also very dense, having a higher specific gravity than other commonly used stone materials. In fact, quartz has a specific gravity of between 2370 and 2400 kg/m³. This means that the material is very heavy and it will take a lot of effort to cause any type of penetration.
A countertop would need to absorb enormous amounts of liquids before it would even begin to show any signs of penetration. The density and weight also make quartz countertops nonporous because it’s very resistant to penetration.
The two main reasons why you should take a look at quartz countertops is because it’s one of the most popular types of stone for countertops these days and because it’s nonporous.
Quartz countertops are made to be durable and able to withstand heavy use. These qualities make quartz countertops a good material for kitchen counters, bathroom vanities, or any other surface that you would want to use every day.
The fact that they are nonporous is just another reason why quartz countertops may be a good option for your home.
Benefits Of Quartz Being Nonporous
Quartz Does Not Absorb Liquids
Quartz being nonporous means that it does not absorb liquids or other substances. One of the best features of quartz countertops is that it does not absorb liquids or other substances.
