Is it really waterproof once dry?

Yes, the cured acrylic film resists water and is rated waterproof. It is a surface sealer, so it will not stop water pushing through a crack under pressure.

How much area does 35 oz cover?

Expect roughly 50 to 100 sq ft per coat on a smooth surface, less on rough brick or concrete. Two thin coats work better than one thick coat.

Can I use it indoors?

Yes. The water-based acrylic is low odor, but ventilate the room while it dries.

Will it change the look of my surface?

It dries clear, though it can add a slight sheen. Test on a hidden spot first, especially on dark stone.

Is $22.99 a good price?

It is the best new price across the two stores listing it as of November 4, 2026. Compare per-ounce cost with larger sealer tubs if you have a big area.

One 35 oz container of clear acrylic coating. Brushes, rollers and trays are not included.
