Concrete Acid Stain | Black 1 Gallon

I used 3 colors. Easy to use

Meticulously prepared the concrete floor before applying the stain. The result was not black, it did leave a cool pattern from the reaction with the concrete but it is not black or even a close to black color. I don't know if I got a faulty or mislabeled jug, but what i got was not black, wet, dry, or in the dark.. not black. It was a rusty copper color. After accusing me of doing it wrong for a day or two through messages I got them to send a black water based stain sample, which was barely enough to test a tiny little area, it was like a 4 oz little bottle. The water based stain was atleast black though..

I bought two colors as i wanted to create a checker board out of some paving stones. I used a sprayer and saturated each of the sets. When they first dried they seemed rather faded, but the instructions mentioned this so i let them set over night and then washed them off a few days later. They actually quite darker and fuller in color within two days. Clean up was easy as well.

First problem was I ordered black stain. The container said it was black. The stain was a dark mustard color. The stain only worked on some of the concrete. It made the the retaining wall look a dingy dark yellow. I would not recommend this product.
