I recently used Eagle Acid stain for concrete in olive color. The concrete slab is going to be used for an outdoor pavilion and was only floated a couple of times with a hand made wooden float. I never touched the cement after the float but when it got firm enough to walk on I sprayed it with water and covered the whole job with plastic. Leaving it covered for 7 days. I waited 28 days for the cement to cure before using the stain. . It took 1.3 gallons for 360 sq. ft.
First I misted water over the entire slab to make it damp. I used a garden style sprayer and went to work spraying the slab. As I went I would stop spraying and broom in the acid with a shop broom working it into the cement evenly. I highly recommend a damp slab to start and brooming the acid in as you go for even coverage. They recommend a sprayer for acid stain but mine was not and I think the brass tip and tube of the sprayer effects the stain somewhat if you stop and it sits- reacting to the brass. In hindsight I recommend using a plastic garden sprinkler watering can. Have a helper do this as you work the acid around with the broom.
The next day I rinsed the slab several times and broomed it with lots of water. Then I mixed 16 OZ. of ammonia with 5 gallons of water, flooding the area and brooming the neutralizer mix in. I did this twice then I rinsed the slab thoroughly again.
I waited a week to seal it and I used Behr Premium Low-Luster Sealer, $28. This produced the look I wanted and took the curse off the olive color. If you want a darker wet look- use the Behr Wet-Look Sealer. Eagle makes a good sealer which I have used in the past also. I was very pleased with the Eagle Acid stain and the Behr Premium Low-Luster Sealer.

The first coat of Acid Stain I used was from another company and cost $20 more per gallon. I was new to the acid stain process and was unsatisfied with the first application. I used a floor maintainer with a black pad and water, buffing the surface well before applying the 2nd coat which was the Eagle Acid Stain. The secret to applying on 1 month old concrete is to dampen the surface before applying. The dampness helps break down the surface tension and lets the acid stain flow in more evenly- you also get better coverage. After spraying the whole job broom in the acid. Keep brooming in the slow drying areas- working it into the concrete. You can walk on the acid stain when wet brooming it in.
After 5 hours I hosed off the acid and used the floor maintainer (red pad), to buff around 2 cups of ammonia mixed with 5 gallons of water to neutralize it. Buff once with the floor maintainer and broom around the ammonia water 2 more times. The buffer will remove some of the stain if you do it to much- use a white pad if concerned about that. I learned much of this on Youtube.
After 24 hours of dry weather I used the Eagle acrylic sealer and was very happy with that product as well. This was an 185 sq. ft. outdoor patio. I am thrilled with the finished look.
