Is Granite A Porous Surface

Polishing the stone creates a flat smooth surface that reduces the porosity.

Is granite a porous surface.

Hard surfaces are a combination of porous and nonporous materials. All natural stone possesses some degree of porosity. How porous your granite countertop is will depend on how it is finished and how it is treated. Granite is less porous than marble.

Granite is one of the most durable materials you can install in your home. The size of these tiny voids along with their surface count determine the porosity level. When a surface is nonporous such as stainless steel it cannot absorb anything at all. Corian is a homogenous nonporous surface that is manufactured by dupont.

Daily kitchen activities pose no problems for granite which can even take on a hot pot without the use of a trivet. Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials. To say water can pass throu. However this doesn t mean granite acts as a sponge.

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. Granite countertops are porous if left unsealed. The surfaces are non porous so you will not have to worry about sealing. While granite is unlikely to ever go out of style the choice for countertop surfaces extends far beyond granite and includes synthetic surfaces like corian natural rocks like marble and engineered quartz like silestone granite a natural rock is extremely hard and durable despite being porous.

Beautiful stronger than oak but porous a gorgeous nearly impenetrable counter top surface granite is highly resistant to scratching cracking and staining and is impervious to heat. Porosity can be swiss cheese or sponge like others have said but it can go down to the nanostructures level like zeolite and aerogel. A non porous surface is microscopically flat and smooth down to the molecular level. The material is also stain resistant.

Often overlooked are details such as the material surface texture. It is stain resistant. Being porous is not necessarily a bad quality. This means granite has tiny crevices or holes that allow air and water into the stone.

You do not want your granite kitchen countertops or surfaces in other rooms to sustain damages as a result of a worn seal. Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. If liquids are left on the surface for long periods of time they will eventually absorb. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials.

Each pore on the surface of granite tiles or slabs is considered to be a microscopic void. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly.
