Purchased 5 gal. AR350, 18" roller tray, rollers (nap per Foundation Armor application notes), and 16oz of grit to re-seal salt water pool stamped concrete deck. Everything showed up within two days (all via Prime). Foundation Armor provided a nice set of instruction on how to prep surface, easy to follow. Added grit to 5 gallon drum, stirred with drill and bent coat hanger, and began to roll. Product coverage was excellent, have used many other brands and this by far was the smoothest to go on and with the recommended roller nap the surface had a nice even coating. 1st coat took about 1hour, applied the second coat ~8hrs later. Highly recommend. This is one of those products that performs exactly as advertised. Well worth the money. AR350 will be part of my annual pool maintenance from now on. With all the dynamic weather conditions, I'm not surprised that a New England based company has perfected the sealer recipe.
