Is Granite Porous

Granite is a porous material.

Is granite porous.

If your granite countertop is stained in most instances it can still be fixed. 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. 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. When a surface is nonporous such as stainless steel it cannot absorb anything at all.

Granite is an igneous rock. By doing this the trinova sealer also provides a protective layer to granite to protect it from any water spotting and other. If liquid or stains get down into the stone it can result in damages and weakening of your granite. The general composition of granite includes silicon dioxide feldspar mica and various minerals.

To better understand the natural porosity of granite it helps to understand the following details. Being porous is not necessarily a bad quality. If liquids are left on the surface for long periods of time they will eventually absorb. 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.

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. 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. Granite is a porous natural stone.

Granite while it is a very hard substrate it is still somewhat porous. Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. The cause of the stain will determine the best way to clean it. This means that if it is not properly sealed liquid is able to penetrate its surface.

Granite is relatively non porous compared to other common countertop materials though it still has some porosity. However this doesn t mean granite acts as a sponge.
