I previously purchased a 5 gallon bucket of Foundation Armor and this additional 1 gallon. I used it to seal my shellac pavers around my pool patio with 2 coats. easy to apply with a roller. I used 1/2 nap roller brush. Water beads on it after rains and will remain beaded up most of the day even with the Florida heat. Little slick when it gets wet. Not sure if i used the right product or if i should have used the AX25. Overall a very good quality sealer.
