There are conflicting philosophies about whether or not to seal granite counter tops. Granite is generally a hard and dense stone that absorbs little or no sealer. That said, most often it can’t hurt to apply sealer as long as it is done correctly.
The one instance where Boston Stone Restoration maintains you should NOT seal granite is with Black Absolute Granite. It is one of the densest stones on the market and as such, doesn’t absorb sealer at all. Instead what happens is the sealer sits on the surface and attracts dirt and food residue and results in smudgy unappealing counter tops.
This was the case with one of our recent clients. They had their black absolute counter tops sealed and the result was a striped effect that couldn’t be removed with stone cleaner. We addressed the problem by honing the top to remove the sealer, resulting in a smooth, clean granite surface. Professionals liken this type of stone to a chalk board, it should be smooth and have a matte finish. Sometimes you will get dark spots when they get wet, but just like a chalk board, those marks evaporate.
