Is Granite Stone Porous

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.

Is granite stone porous.

Granite is an igneous rock. Granite is a porous material. If liquids are left on the surface for long periods of time they will eventually absorb. However this doesn t mean granite acts as a sponge.

Where the water and oil if used was placed on the granite check for darkening of the stone. If liquid or stains get down into the stone it can result in damages and weakening of your granite. When a surface is nonporous such as stainless steel it cannot absorb anything at all. Marble is also fairly porous but not as much as limestone and sandstone.

For example black granite surfaces are extremely dense and do not require any form of sealing. Granite is a porous natural stone and without the sealer oil grease dirt and water will seep into the surface and spoil the look. This means granite has tiny crevices or holes that allow air and water into the stone. Some types of natural stone are more porous than others.

Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. So natural stone countertops are porous and some are more porous than others. To better understand the natural porosity of granite it helps to understand the following details. This indicates that the granite has absorbed the liquid meaning it s porous.

Even worse germs bacteria and mold can invade unsealed granite counter tops with stains running not far behind. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble. By doing this the trinova sealer also provides a protective layer to granite to protect it from any water spotting and other. Having said all of that you need to keep in mind that not all granite surfaces require sealing.

If the water beads up and seeps into the stone within 5 minutes you have a porous stone or the sealer has started to wear off. Being porous is not necessarily a bad quality. This means that if it is not properly sealed liquid is able to penetrate its surface. Whenever you get porous granite countertops wet you run the risk of them becoming discolored.

Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. If the water doesn t bead up bus immediately darkens and soaks into the stone right away it is important to apply the sealer as soon as possible to avoid any staining. 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.
