Is Granite Porous

Granite is relatively non porous compared to other common countertop materials though it still has some porosity.

Is granite porous.

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. Most water marks will disappear once they ve completely evaporated but if your granite is very porous or the spill was large you might end up with a dark discoloured area. This means granite has tiny crevices or holes that allow air and water into the stone.

When a surface is nonporous such as stainless steel it cannot absorb anything at all. Granite is an igneous rock. If liquid or stains get down into the stone it can result in damages and weakening of your granite. This means that if it is not properly sealed liquid is able to penetrate its surface.

The trinova granite sealer utilizes the powerful blend of polymers that penetrates the stone or granite s natural porous surface to prevent any stains from seeping into the surface and becoming a permanent stain. Granite while it is a very hard substrate it is still somewhat porous. The general composition of granite includes silicon dioxide feldspar mica and various minerals. If liquids are left on the surface for long periods of time they will eventually absorb.

By doing this the trinova sealer also provides a protective layer to granite to protect it from any water spotting and other. If your granite countertop is stained in most instances it can still be fixed. Primarily the sealing is done to keep harmful bacteria from penetrating the stone and transferring to food items. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble.

Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. 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. However this doesn t mean granite acts as a sponge.

Limestone and sandstone are highly porous and readily absorb liquids and are particularly prone to etching and wearing away when they come into contact with acids. Granite is a porous natural stone.
