Is Granite Porous Or Nonporous

Answer 1 of 1.

Is granite porous or nonporous.

Even worse germs bacteria and mold can invade unsealed granite counter tops with stains running not far behind. Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. Just last week i inspected a granite that had severe water damage so you never know here s a test you can perform. Often overlooked are details such as the material surface texture.

If the area is darker then the rest of your granite it means that it has adsorbed some of the water rendering it porous. Granite is an igneous rock. The general composition of granite includes silicon dioxide feldspar mica and various minerals. Granite is usually non porous but there are exceptions.

All natural stone possesses some degree of porosity. Put a few drops of water on it and wait 30 minutes. Polished granite is the most durable most granite countertops are polished then sealed making them nearly impermeable. Being porous is not necessarily a bad quality.

Granite is a porous material. Primarily the sealing is done to keep harmful bacteria from penetrating the stone and transferring to food items. Granite countertops are porous if left unsealed. How porous your granite countertop is will depend on how it is finished and how it is treated.

Hard surfaces are a combination of porous and nonporous materials. This means granite has tiny crevices or holes that allow air and water into the stone. Granite is a porous natural stone. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble.

If liquids are left on the surface for long periods of time they will eventually absorb. Alas its porous surface is granite s kryptonite. Like all natural stone granite is susceptible to liquid sinking into its surface. Also granite is immune from the damages of most common household acids.

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. To better understand the natural porosity of granite it helps to understand the following details. Come back and wipe the area.

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. Granite while it is a very hard substrate it is still somewhat porous.
