How Quartz prevents staining

Statuario Milane

Oh no! I spilled wine on my countertop! Will it stain?

Is your countertop quartz or FriTech™? You’re in luck!

Unlike marble and granite countertops, which need to be sealed frequently to prevent staining. So, naturally, the question comes up, quartz and FriTech are naturally stain-resistant. How is that possible? It all comes down to quartz’s low porosity thanks to its unique production.

Let’s take a look at the unique elements of quartz that make this an excellent, stain-resistant, surface for your home.

What is porosity?

Porosity refers to the presence and composition of pores – small holes – within a material. With natural stones, such as granite and marble, pores are an essential component of their structure. Stone is comprised of crystallized minerals that are pressed together into very compact structures. However, gaps remain between the crystals of minerals. These gaps are what we call pores.

Pores, which allow air and water to flow through the material, are formed in different ratios depending upon how the stone itself is created. For sedimentary stones such as limestone, the process results in a significantly high percentage of pores – up to 30%! This makes limestone significantly lighter than less porous stone, like granite. It also means that water can seep into the stone much more easily.

How porous are mined stones?

Two popular mined stones, marble and granite, have significantly different levels of Porosity. Marble has a porosity of around 2%, while granite has a porosity of around 0.4-1.5%. Granite, too, needs to be sealed to prevent stains.

Why is Quartz stain-resistant?

Quartz is resistant because it is non-porous. The unique manufacturing process of engineered surfaces creates a stone that has no microscopic holes for liquids to seep through. Engineered stone, such as quartz or Lucciare’s new, eco-friendly FriTech, combines high-quality crystalline minerals with durable resins to produce engineered surfaces harder and more stain-resistant than granite.

Since there are no pores on the surface of quartz, any spilled liquid doesn’t have the chance to seep into the structure. This means that quartz is non-permeable in addition to being non-porous. Instead, you can simply wipe the liquid off the surface with a non-abrasive cloth. For potential surface-level stains, check out our guide on how to lift a stain from your quartz countertop.


Quartz: non-porous, stain-resistant.

Thanks to quartz’s unique properties, it serves as a non-porous surface that doesn’t need to be sealed. You no longer have to worry about has it been too long since I sealed my countertops? You no longer have to think oh, be careful with that glass of wine.

Quartz takes the worry out of maintaining your surfaces. Stain-resistant, durable, and elegant; it provides an exciting and practical addition to any home.
