Is Granite A Non Porous Surface

Granite countertops are porous if left unsealed.

Is granite a non porous surface.

Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. The undisputed unbeaten champion of the porous test quartz is non porous. However this doesn t mean granite acts as a sponge. This means granite has tiny crevices or holes that allow air and water into the stone.

Granite countertops are considered to be alow maintenance countertop surface. Quartz s non porous nature allows it to resist staining much better than granite marble and concrete. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. Each pore on the surface of granite tiles or slabs is considered to be a microscopic void.

Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials. The surface no acidic opponent can beat. You do not want your granite kitchen countertops or surfaces in other rooms to sustain damages as a result of a worn seal. Polishing the stone creates a flat smooth surface that reduces the porosity.

Often overlooked are details such as the material surface texture. Are quartz countertops porous. The likelihood of needing to be repaired or resurfaced is low. Many nonporous countertops are manufactured today including solid surface corian and the many quartz products like cambria silestone and corian quartz.

Hard surfaces are a combination of porous and nonporous 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. As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone. 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. There are many attractive porous countertop options as well granite for example is a popular but porous countertop surface. These surfaces are engineered stone that is created by combining roughly 90 percent ground natural quartz with about 10 percent polyresin. There are things that can stain them though such as permanent marker which can be removed from granite.

Granite is less porous than marble. The size of these tiny voids along with their surface count determine the porosity level. All natural stone possesses some degree of porosity. When a surface is nonporous such as stainless steel it cannot absorb anything at all.

However on a non porous or sealed surface water will bead up. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials. Other countertop materials such as solid surface and quartz surfacing are non porous. This means water other liquids and even bacteria can enter the countertops surface even causing granite to darken or marble to stain.
