Is Granite Stone Porous
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.
Is granite stone porous. Granite is a porous natural stone. However this doesn t mean granite acts as a sponge. This means that if it is not properly sealed liquid is able to penetrate its surface. By doing this the trinova sealer also provides a protective layer to granite to protect it from any water spotting and other.
Alas its porous surface is granite s kryptonite. If liquid or stains get down into the stone it can result in damages and weakening of your granite. 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. Staining is also a problem with more porous stones especially darkly colored liquids like red wine.
Granite is a naturally porous stone though it s not as porous as some other types of natural stone like marble. This means granite has tiny crevices or holes that allow air and water into the stone. Being porous is not necessarily a bad quality. Having said all of that you need to keep in mind that not all granite surfaces require sealing.
For example black granite surfaces are extremely dense and do not require any form of sealing. Some types of natural stone are more porous than others. For example limestone is very porous when compared to quartzite and granite isn t as porous as marble. So natural stone countertops are porous and some are more porous than others.
This indicates that the granite has absorbed the liquid meaning it s porous. Marble is also fairly porous but not as much as limestone and sandstone. To better understand the natural porosity of granite it helps to understand the following details. A big red mark is the last thing you want on your pure white marble slab.
Granite is an igneous rock. Like all natural stone granite is susceptible to liquid sinking into its surface. 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. Where the water and oil if used was placed on the granite check for darkening of the stone.
Also granite is immune from the damages of most common household acids. Granite is a porous natural stone and without the sealer oil grease dirt and water will seep into the surface and spoil the look. If liquids are left on the surface for long periods of time they will eventually absorb. Granite is a porous material.
When a surface is nonporous such as stainless steel it cannot absorb anything at all.
