Is Granite Porous Or Nonporous

Alas its porous surface is granite s kryptonite.

Is granite porous or nonporous.

Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. Also granite is immune from the damages of most common household acids. Polishing the stone creates a flat smooth surface that reduces the porosity. Come back and wipe the area.

Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. Primarily the sealing is done to keep harmful bacteria from penetrating the stone and transferring to food items. Granite is usually non porous but there are exceptions. Common hard surface materials are stainless steel solid surface laminate porcelain and a wide variety of tile and ridged plastic materials.

How porous your granite countertop is will depend on how it is finished and how it is treated. If liquid or stains get down into the stone it can result in damages and weakening of your granite. Some of the more common porous surfaces include laminate granite and various types of tile and plastic materials. This means that if it is not properly sealed liquid is able to penetrate its surface.

To better understand the natural porosity of granite it helps to understand the following details. Granite is a porous material. If the area is darker then the rest of your granite it means that it has adsorbed some of the water rendering it porous. This means granite has tiny crevices or holes that allow air and water into the stone.

If liquids are left on the surface for long periods of time they will eventually absorb. Often overlooked are details such as the material surface texture. When a surface is nonporous such as stainless steel it cannot absorb anything at all. Hard surfaces are a combination of porous and nonporous materials.

Granite while it is a very hard substrate it is still somewhat 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 porous if left unsealed. Answer 1 of 1.

Granite is a porous natural stone. Being porous is not necessarily a bad quality. Granite is an igneous rock. Like all natural stone granite is susceptible to liquid sinking into its surface.

For example limestone is very porous when compared to quartzite and granite isn t as porous as marble. Just last week i inspected a granite that had severe water damage so you never know here s a test you can perform. All natural stone possesses some degree of porosity.
