Is Quartz Porous
Is Quartz Porous?
Porosity is the single property behind most of quartz’s practical advantages. Here is whether quartz is porous, and what it means for your kitchen.
The short answer
Non-porous surface
Quartz is non-porous.
Liquids cannot soak in, which is why it resists stains and needs no sealing.
non
Porous surface
0
Sealing needed
No, quartz is non-porous. Because it is engineered from around 93% crushed quartz bound with resin into a dense slab, there are no open pores for liquids to soak into. This single property is behind most of quartz’s practical advantages: it resists staining, it never needs sealing, and it is hygienic because nothing can soak in and harbour bacteria. Natural stones such as granite and marble are porous to varying degrees. To go further, read whether quartz needs sealing and whether quartz stains.

Is quartz porous? What it means
The short answer
Quartz is non-porous. This is one of the defining features of the material and the reason behind several of its practical benefits. It is worth understanding because porosity, or the lack of it, affects staining, sealing and hygiene. Our FAQ on what quartz is made of covers the structure.
Why quartz is non-porous
Quartz worktops are engineered from around 93% crushed quartz bound with resin and compacted into a dense slab. That process leaves no open pores, so liquids sit on the surface rather than penetrating it. Our FAQ on what a quartz worktop is explains the engineered structure.
What non-porous means for stains
Because nothing soaks in, quartz is highly resistant to staining from wine, coffee, oil and citrus. Spills sit on top and wipe away. Our FAQ on whether quartz stains covers this in detail.
What non-porous means for sealing and hygiene
A non-porous surface never needs sealing, unlike porous natural stone, and it is hygienic because bacteria cannot soak in and lodge below the surface. Our FAQs on whether quartz needs sealing and whether quartz worktops are hygienic cover both.
How quartz compares with natural stone
Granite and marble are porous to varying degrees, which is why they are sealed and re-sealed. Quartz removes that whole task. Our FAQ on quartz versus granite worktops compares the two. Precious Marble supplies and fits non-porous quartz from its Bedford base. See the Quartz Worktops Bedford page to start.
