Applied this to my honed marble bathroom floor. It soaked in perfectly and now water beads right up. No change to the stone’s look, which is exactly what I needed. Great product.

Used it on our new slate patio. The sealer was easy to work with and has held up well through several rainstorms. It really does repel water without making the stone look wet or glossy.

Followed the instructions on my unglazed tile backsplash. It took two coats, but now red wine and oil wipe right off. Saved me a lot of worry about stains in the kitchen.
