This is the drive after staining. The stain commonly used on concrete is acid based, requiring protective gear and the protection of plants. It is also quite expensive, particularly for the large area we had to color.
We learned about an alternative and decided to try it. It is Iron Sulfate, which is an acid type fertilizer. (Referred to as Copperas in TX.) It is merely mixed with water and applied with a hand sprayer. Any runoff benefits the grass. There is only one series of shades, all of an orange-red hue, depending upon the concentration and number of coats applied. Since it was the same general color as the house it was perfect. It is permanent, does not fade much, and really muted the brightness and glare of the native concrete. Enough to do the entire drive cost $5.
