Plus, the spray nozzle distributes the product evenly, so I didn’t waste any on overspray or missed spots.

Coverage is impressive—up to 75 linear feet per 16 ounces, per coat, which means I didn’t have to buy multiple bottles. The product also claims to last up to 5 years without resealing, so peace of mind is built-in.

After sealing, I rinsed off some dirt and stains easily, thanks to its moisture barrier that keeps grime from settling into the grout.

One thing I appreciated was how quick and clean the whole process was. Wiping off excess was simple, and I could get back to my day without any fuss.

It’s a solid choice for anyone tired of dealing with stubborn stains or harsh fumes during sealing.
