There are better sealers for porous stone. This may well be used for grout only. Needs more company testing.
You're going to need way more than a pint. Go for a larger portion. Maybe I didn't apply enough sealer to the travertine. I tried to follow directions, but the print was so miniscule and there's not much manufacturer support over phone on a weekend.
There are better products that bead water after a preseal. This one is overpriced and overpowered with false advertising.
