Foundation Armor provided a nice set of instructions on how to prep surfaces for the best results, Instructions were easy to follow on a little postcard that was included in the box. Product coverage was excellent and used way less than estimated! I have used many other brands and this by far was the smoothest to go on and the best appearance. I Highly recommend this brand to anyone! This is one of those products that performs exactly as advertised and the transformation results are exactly as pictured. Well worth the money. AR350 will be part of my annual patio maintenance from now on with all the dynamic weather conditions Wisconsin experiences! See pictures for before and after. Words can't justify the difference in my stained patio.
