I wanted a color coating product for my basement walls and decided on the AR500 after talking with customer support.  It was too easy to apply.  I mixed in the light gray color tint with my 5 gallon bucket of AR500 and then rolled on two coats.  Almost one year after application, the coating still looks great.  I was told that the Armor acrylic products can breathe which prevents the coating from failing.  I recommend this product.
