Customer wanted a curb appeal package because he was putting the home on the market as a rental. The back patio had years of growth built up so we pretreated it with our concrete cleaner mix and the surface cleaned the area followed by a post treat of the area. The bricks around the front of the house had moss growing so we saturated the area with water and then applied our concrete mix, let it kill all of the moss and algae then rinsed away.
