Is granite a porous stone.

Granite is relatively non porous compared to other common countertop materials though it still has some porosity. Being porous is not necessarily a bad quality. Even worse germs bacteria and mold can invade unsealed granite counter tops with stains running not far behind. Alas its porous surface is granite s kryptonite.

This means that if it is not properly sealed liquid is able to penetrate its surface. Like all natural stone granite is susceptible to liquid sinking into its surface. Granite countertops are porous if left unsealed. All natural stone possesses some degree of porosity.

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. Most fabricators will apply a sealer to granite countertops before they are installed which will protect them from absorbing liquids too quickly. If liquids are left on the surface for long periods of time they will eventually absorb. Granite is a porous natural stone.

Polished granite is the most durable. Like all of the products provided by granite gold granite gold sealer is safe to use on all types of natural stone including marble travertine and slate. Also granite is immune from the damages of most common household acids.
