A sealant isn't necessary, but I do use one just to give a little protection for the first few years as the stone hardens up. The stone is softer when first quarried since it has been sitting in ground moisture for a few hundred million years. It dries out considerably in the first couple of months, then more slowly over the next years. The sealant is transparent and breathable, meaning moisture that gets in isn't trapped but can permeate out. It also only lasts for perhaps 3 to 6 years outside (it lasts much longer on indoors pieces), so it basically helps avoid staining and makes cleaning a little easier until the stone matures.Outstanding Walter !
Do you seal the limestone when you are finished?
It looks awful porous
