I used this product to seal a concrete paver pool deck, about a year old, never been sealed.
I followed the publised guidelines, applied with rollers, and the experience was uneventful. Beads up with rain and keeps a gloss look. In addition, the product does a great job "locking" in the sand between paver joints. I wish I had done this when the deck was new.
I applied 1st coat with 1/2" nap roller to ensure I got some excess between the paver joints, followed by 2nd coat with 3/8" nap roller.
I think the spread rate for the material is a little off, as the first coat took somewhat more than I expected, but then again, I applied excess to better lock the sand between the paver joints. Also, the cure time seemed to be slightly less than what is published (which isn't a bad thing), but to be fair, I was working in Florida's good warm sunshine.
