There are several factors you will need to consider when choosing a natural stone or quartz countertop for your kitchen, and one such factors is known as porosity. Referred to in states of either porous or non-porous, this quality speaks to how well a given surface resists the passage of air and moisture into the deeper structural area of the material – materials that are highly porous risk more of these elements seeping through and causing damage.
At Accent Interiors, we have a wide range of custom countertops with differing porosity ranges available. In addition, we can explain to you additional factors related to porosity and your countertop needs, including ways you can protect your surfaces even if you choose a product that’s more porous than some others.
If you’re looking for the top natural stone material out there when it comes to porosity, look no further than quartz. Quartz is a completely non-porous material, meaning it resists staining and other invasions from moisture or air. No matter what is spilled on the surface, from basics like water to extremely harsh elements like oil, tomatoes, coffee or others, the surface will repel it fully.
In addition, quartz surfaces are known for their cleanliness. They will not retain bacteria, viruses or other similarly harmful particles, and are the simplest to clean among related countertop surfaces. And finally, quartz maintains these qualities while being available in a huge variety of colors.
There are certain protective qualities where granite is top-notch – it is super resistant to scratching and various cracking or other damage, plus will not stain easily and can manage high amounts of heat. This makes it perfect for a number of cooking needs.
However, you have to be careful when it comes to liquids and air passage – granite is porous, unlike quartz. Non-sealed granite is left open to various liquids seeping through the surface, and may also be susceptible to bacteria or germs if you aren’t careful. Some colors or stones might be more porous than others.
Luckily, there’s a simple solution here: Stone sealers. There are several high-quality penetrating sealers available specifically for granite materials, helping prevent stains from various liquids. Regular use of these protective products goes a long way to removing this risk.
Marble offers the fewest protections of these three options, with porous qualities plus a softness and greater risk for scratching and durability issues. It’s particularly susceptible to acidic products like vinegar, citrus and others, which can etch the marble surface and remove its beautiful polish.
Like with granite, it’s prudent to seal all your marble surfaces regularly. We recommend sealants with no volatile organic compounds. If you’re just sealing for the first time, expect to use a lot of product – marble will soak up sealant and may require multiple applications.
