Is Granite A Porous Surface

The surfaces are non porous so you will not have to worry about sealing.

Is granite a porous surface.

How porous your granite countertop is will depend on how it is finished and how it is treated. All natural stone possesses some degree of porosity. Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. Hard surfaces are a combination of porous and nonporous materials.

Corian is a homogenous nonporous surface that is manufactured by dupont. Granite is a porous material. Daily kitchen activities pose no problems for granite which can even take on a hot pot without the use of a trivet. The size of these tiny voids along with their surface count determine the porosity level.

Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials. Granite countertops are porous if left unsealed. When a surface is nonporous such as stainless steel it cannot absorb anything at all. The material is also stain resistant.

Each pore on the surface of granite tiles or slabs is considered to be a microscopic void. Granite is one of the most durable materials you can install in your home. Porosity can be swiss cheese or sponge like others have said but it can go down to the nanostructures level like zeolite and aerogel. Often overlooked are details such as the material surface texture.

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. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. On the downside laminate countertops typically only last for about 10 years or so before you should replace them. 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. Granite is less porous than marble. 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.

A non porous surface is microscopically flat and smooth down to the molecular level. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials. It is stain resistant. This means granite has tiny crevices or holes that allow air and water into the stone.

However this doesn t mean granite acts as a sponge. Being porous is not necessarily a bad quality. As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone.
