A:Covington Grass Paint is best applied with a pump sprayer. The amount of concentrate needed to match your grass color will vary based on grass type and the shade of green you are aiming for. Start with a less concentrated mixture and test a small area for color matching. Keep adding concentrate until you are satisfied with the color match. For dull/light green test mixing 4-6 oz. of concentrate per gallon of water and for brown dormant grass test a little more concentrate around 8-10 oz. per gallon.
