Is Granite Non Porous

Granite is a porous natural stone.

Is granite non porous.

All natural stone possesses some degree of porosity. There are things that can stain them though such as permanent marker which can be removed from granite. Quartz can repel the harshest spills from juice to oil to tomatoes coffee and more. Granite countertops are considered to be alow maintenance countertop surface.

Granite is relatively non porous due to the interlocking nature of the crystallized minerals which it contains. Quartz s non porous nature allows it to resist staining much better than granite marble and concrete. Countertop surfaces natural stones such as granite and marble have pores and are considered porous surfaces. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable.

It is my understanding that all granites by nature have some amount of porosity no matter how slight. Limestone and sandstone are highly porous and readily absorb liquids and are particularly prone to etching and wearing away when they come into contact with acids. Its non porous surface means it will not harbor bacteria or viruses. Other countertop materials such as solid surface and quartz surfacing are non porous.

Even though granite isn t as porous as other stones it still needs to be sealed. If liquid or stains get down into the stone it can result in damages and weakening of your granite. The likelihood of needing to be repaired or resurfaced is low. This means that if it is not properly sealed liquid is able to penetrate its surface.

The undisputed unbeaten champion of the porous test quartz is non porous. Granite countertops are porous if left unsealed. The short answer to this question is yes. This means water other liquids and even bacteria can enter the countertops surface even causing granite to darken or marble to stain.

Granite is relatively non porous compared to other common countertop materials though it still has some porosity. How porous your granite countertop is will depend on how it is finished and how it is treated. However on a non porous or sealed surface water will bead up. When a surface is nonporous such as stainless steel it cannot absorb anything at all.

This means granite has tiny crevices or holes that allow air and water into the stone. Like all of the products provided by granite gold granite gold sealer is safe to use on all types of natural stone including marble travertine and slate.
