Is Granite A Non Porous Surface

Quartz is a non porous material.

Is granite a non porous surface.

Each pore on the surface of granite tiles or slabs is considered to be a microscopic void. The undisputed unbeaten champion of the porous test quartz is non porous. Often overlooked are details such as the material surface texture. Granite countertops are porous if left unsealed.

Polishing the stone creates a flat smooth surface that reduces the porosity. This means water other liquids and even bacteria can enter the countertops surface even causing granite to darken or marble to stain. As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone. When a surface is nonporous such as stainless steel it cannot absorb anything at all.

While granite is not the most porous natural stone countertop option it is still porous and you will need to seal the surface to protect it from liquid damage and stains. Quartz can repel the harshest spills from juice to oil to tomatoes coffee and more. Quartz s non porous nature allows it to resist staining much better than granite marble and concrete. The size of these tiny voids along with their surface count determine the porosity level.

Many nonporous countertops are manufactured today including solid surface corian and the many quartz products like cambria silestone and corian quartz. All natural stone possesses some degree of porosity. These surfaces are engineered stone that is created by combining roughly 90 percent ground natural quartz with about 10 percent polyresin. However this doesn t mean granite acts as a sponge.

However on a non porous or sealed surface water will bead up. There are things that can stain them though such as permanent marker which can be removed from granite. This means granite has tiny crevices or holes that allow air and water into the stone. Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials.

In terms of natural stone countertop options materials like granite are on the less porous side whereas a material like limestone is very porous. Granite is less porous than marble. Are quartz countertops porous. Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble.

Granite countertops are considered to be alow maintenance countertop surface. There are many attractive porous countertop options as well granite for example is a popular but porous countertop surface. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials. Hard surfaces are a combination of porous and nonporous materials.

Other countertop materials such as solid surface and quartz surfacing are non porous. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. You do not want your granite kitchen countertops or surfaces in other rooms to sustain damages as a result of a worn seal. The likelihood of needing to be repaired or resurfaced is low.
