Is Granite Porous Or Nonporous

Being porous is not necessarily a bad quality.

Is granite porous or nonporous.

Often overlooked are details such as the material surface texture. If liquid or stains get down into the stone it can result in damages and weakening of your granite. All natural stone possesses some degree of porosity. Alas its porous surface is granite s kryptonite.

The general composition of granite includes silicon dioxide feldspar mica and various minerals. Granite countertops are porous if left unsealed. Granite is an igneous rock. If liquids are left on the surface for long periods of time they will eventually absorb.

To better understand the natural porosity of granite it helps to understand the following details. Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials. Granite while it is a very hard substrate it is still somewhat porous. Hard surfaces are a combination of porous and nonporous materials.

Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. Even worse germs bacteria and mold can invade unsealed granite counter tops with stains running not far behind. Granite is a porous material. When a surface is nonporous such as stainless steel it cannot absorb anything at all.

Granite is a porous natural stone. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials. Polishing the stone creates a flat smooth surface that reduces the porosity.

Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. Granite is usually non porous but there are exceptions. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. Answer 1 of 1.

This means granite has tiny crevices or holes that allow air and water into the stone. Primarily the sealing is done to keep harmful bacteria from penetrating the stone and transferring to food items. Put a few drops of water on it and wait 30 minutes. This means that if it is not properly sealed liquid is able to penetrate its surface.

Like all natural stone granite is susceptible to liquid sinking into its surface. How porous your granite countertop is will depend on how it is finished and how it is treated. If the area is darker then the rest of your granite it means that it has adsorbed some of the water rendering it porous.
