Why Countertop Surfaces Are Porous (and What Does That Mean?)

Are you looking to purchase custom countertops for your home? You may have come across the terms “porous” and “non-porous” in some of the descriptions of the various surfaces. It’s essential to have a basic understanding of what these terms mean so you can choose the right countertop type for your needs.

What Is a Porous Surface?

A pore is a microscopic hole on the surface of a material. When you hear that a countertop material is porous, it means that it contains pores that allow liquids, air and even bacteria to penetrate the surface. Over time, this can cause the countertop to darken or stain, which can detract from its appearance. The permeable nature of these countertops also makes them more difficult to clean. Even a thorough wiping will not prevent all the materials from escaping through the minuscule pores.

Why Are Countertops Porous?

Some popular countertop surfaces consist of natural stone such as granite, limestone and marble. The materials are naturally porous — there is no way to alter their structure to eliminate the pores. While these stone countertops are among the most beautiful, they require the application of a sealant to keep air and moisture out. If you purchase a porous countertop, the installer will need to seal it just after installation. You will also need to re-seal it at least once a year for as long as you own it.

What Is a Non-Porous Surface?

In contrast to a countertop with a porous surface, a non-porous countertop will prevent liquids and other materials from penetrating. These products may consist of quartz, a crystalline mineral that is naturally non-porous. Other options include synthetic products such as Corian® and Meganite®, which are solid surfaces made from combinations of engineered stone and polymers. These man-made offerings are sealed during manufacturing to prevent porosity.

Porous vs. Non-Porous: Which Is Right for You?

Some buyers prefer the “high-end” countertop materials like granite and marble and are willing to incur the extra labor and expense it requires to maintain them. For these homeowners, there is nothing like the look and feel of natural stone. Others want a surface that looks great and requires minimal upkeep. How you feel about these factors should play a significant role in whether you choose a porous or non-porous surface for your home.
