Sealant creates a barrier against liquids that can stain stone. The necessity of resealing varies by stone type, usage intensity, and cleaning habits. Lighter, more porous stones like marble require more frequent attention than dense granites. If water droplets remain on the surface as beads rather than soaking in, the sealant is functioning properly.

How often should natural stone countertops be sealed for protection?
Natural stone countertops should generally be sealed every 6 to 12 months, depending on the porosity of the stone and the frequency of use. A simple 'water test'—where you drop water on the surface and watch for absorption—can help determine if the seal is intact.
