Is Granite Porous or Non-porous?

Granite is not 100% non-porous although it has very little porosity in comparison to other natural countertops. Why porosity of granite is related to cleaning and disinfecting?

The porosity of any natural stone depends on how it is formed in nature. Under intense heat and pressure compacting of crystals take place. Tiny gaps are left at microscopic levels which are also called pores. Depending on material these pores can be of different sizes.

Granite is kind of igneous stone, which have lower porosity in comparison to metamorphic and sedimentary stones. This means your countertop can absorb oil, juice, wine or other substances with time. But on the other hand, it has an easy fix. Sealing at the time of installation and regularly after that can fix your problem.

What to do & what you should not

  • It is very important to have your granite sealed at the time of installation. Sealing of granite and regularly after every two years will make it more stain resistant.
  • Even with sealing it doesn’t mean they are 100% non-porous. Next times if you spill wine or oil over the counter don’t forget to clean up.
  • If you spill anything remember to blot up rather than wiping the spill. You don’t want to spread the spillover to a larger area by wiping them. Easy fix for this is 1st put the paper towel over the spill and then let it absorb the liquid.
  • Don’t use harsh cleaning solution like bleach or ammonia. Anything with acidic material like lemon or vinegar should be avoided too. These materials can harm your granite sealing with time. Easy fix for this is to use mild dish soap with warm water in equal proportions.
  • Don’t use the abrasive material to clean granite countertops. Again this can harm the sealing of your granite. It’s more preferable to use the soft washcloth or microfiber cloth

Why you need to use reseal your granite

As we discussed above granite is not 100% non-porous. Having it sealed at the time of installation and every 2 years after that is very important. It will not only keep it stainproof but also make it shiny as new. Stone Sealers normally have a combination of solvent and resin. When you apply sealer, solvent helps it to get absorbed under the surface. The resin in the sealer helps to fill the pores of the granite and helps in blocks absorption of spilled substances. The solvent of sealer evaporates after some time leaving the layer of resin only.
