I had to replace an area of existing cultured stone next to the front door of my house. Unfortunately, the original stone variety had been discontinued years ago. A mason mixed 3 different varieties of stone to come up with a somewhat close match. I then purchased 3 different kinds of these GenStone Paint Kits to try to get the replacement stone to look as close as I could to the rest of the stone. I blended the numerous paints and diluted them with water to color and tint areas of the new stone that didn't quite match the remaining stone, and the results turned out great. This product is very useful for painting any kind of cultured stone.
