For a wet look stone sealer you want to go with a solvent based acrylic lacquer coating that can penetrate into the small pores of the stone and bond to the surface.

For  best results, make sure the stones are large enough to maintain a coating and if they are small, make sure they are secured with a cement based material, or polymeric sand.

If you don’t want a wet look, or a gloss, you can add a matte packet to a solvent based acrylic, or you can apply a penetrating water repellent silane siloxane sealer.

How to Apply a Wet Look Stone Sealer

Stone is not very porous. In fact, the surface of stone is usually very smooth and the pores are very small. For this reason, it is important to make sure the stone is clean and completely dry. Start by applying one thin coat of the solvent based acrylic. Make sure the entire area is covered and that the coating is even. During the recoat window, apply a second coat the same way. Allow the sealer to properly dry and do not apply when it is expected to rain.
