There are thousands of countertop materials to choose from, and some require more a little love to ensure a long life.
Why Do Stone Countertops Need Sealing?
There are thousands of different of Natural Stones in the market and some of them have very low porosity while others are more porous. Nowadays most stones slabs are sealed in the factory before polishing in a process called "resin treatment". This process upgrades Natural Stones' mechanical features making them more resistant than they would have been in their natural state. On top of that, after your stone is cut into a countertop and installed, you can seal it with an 'impregnator sealer" containing resins molecules that are transported by water or solvents to penetrate the stone's surface at a greater depth, creating a protective seal and barrier from liquid stains.
