Concrete Acid StainSemi-Transparent Professional Grade Cement Stain (Azure Sky, 1 Gallon)

I used this on a polished concrete slab below a woodstove. I had to get a second color to achieve the exact look desired, but the final result is stunning. I wanted to pick up the colors of the natural stone wall behind the stove as well as some of the tone in the wood floor in the room. With a little experimenting I got exactly what I wanted. The result is a variegated natural looking effect that draws positive comments from visitors who often express complete surprise that it is actually concrete. The color has a lot of depth and changes subtly in different lighting, the effect is fantastic. This is a true stain, it can't be scratched off like a paint and the color is deep into the concrete. Directions were sparse but a quick call to the manufacturer found a company with friendly staff who were very happy to help and offer advice on using their products. Excellent service. Keep in mind that the actual concrete mix will have a large effect on the final color, so what you see in the picture may not be exactly what you wind up with. This is the nature of this type of stain and not negative comment on the product - just something to be aware of. The chemicals in the stain "react" with the concrete to give the color - a small variation in the mix or sand type etc. will change the final result - not that you will end up with blue when you ordered red - but the shading and tone may be different. You may need to experiment a bit to get what you want - but the end result is worth the effort. I used this and the "Mountain Road" color together - The colors by themselves have variations in their tones, but I blotted some extra of the two colors on in a few areas to vary the darkness a bit and give it a more visually interesting pattern.

I saw beautiful pictures online but was skeptical if i could actually use it. It is super easy to use. This is NOT gel like, but very thin and watery. I was able to use a squeegie to move it around some though but had to move quickly to do that before it soaked in and dried. I did make some splashes but thats ok because we have to paint anyway. It is a good bit of product, but a little more pricey than other brands. It comes out yellow and gradually moves to a more rusty color. Blended beautifully with an acrylic paint mixture i made to create the green/blue color. I had quite a bit of stuck on glue left after removing old green carpet. I was hoping this might dye it a little but it doesn't so be aware of that. Excellent product! 5 out of 5. Am purchasing again to complete my entire hone & outdoor areas.

After doing hours of research to find a product that I thought would work for my application, I bought and applied this product as directed to a freshly poured concrete pad (I actually waited 30-days after it was poured to be sure it was set). I applied it diluted first, and then went back and added more for color variation. I finalized it with a neutralizer. I followed all directions. I’m disappointed in the outcome because the color is slugging off like chalk to the point that even waking on it a week later is taking the color off down to the original concrete. It seems to have just left a chalky residue and the surface and didn’t permeate into the concrete. I’m going to have to strip all 600 sq ft and refinish with something else. So bummed to have wasted the money on this. I contacted the company about this before leaving my review to give them a chance to rectify the issue and they basically blew me off. I do not recommend using this product for any long lasting concrete coloring.

This is a great product if you like do-it-yourself projects. My wife and I were able to stain our new 1600 sq ft broomed concrete driveway in a day. We waited until the driveway was water cured and dried, about 3-4 weeks after pouring the concrete. Then we sprayed on, with a garden sprayer, a mixture of 1 part of Golden Sand and 2 parts of diluent CR-645. The driveway was neutralized with dilute ammonia after 1-2 hours and then washed off with a hose. After a few days the driveway was sealed by us by spraying on a DoT-approved silicate concrete sealer. And viola: the result was beautiful and water repellent, and we saved thousands of dollars doing it ourselves.

Easy to apply and work with, but color was not at all what I expected—I think the bottle was mis-labeled. I ordered Honey-oat, but the color at the end looks just like their Golden Sand! I am going to try and amend this by blending a second color. Overall, happy working with product, but disappointed with color. (I used their Moss green and that color turned out fine)

Get more stain than you think you'll need. I think it is diluted compared to other products I've used. I purchased 2 gallons of stain which was more than enough for my other projects with different brands. This stain indeed did change the color of the concrete but not as potent as some. I should have had another gallon or two so definitely buy more than you need. Would I buy this brand again? Yes probably but I would definitely go double

Black walnut, defiantly dark. If you're looking for dark brown almost black this is it. seems to continue working for hours after applying. results will be different on different types of concrete.

Trust the process. Half way through I thought it was going to turn out horrible. But it turned out great and we love it. I made sure our concrete was super clean and etched it before adding the stain. I sprayed mine in with a mixture of 3 parts water, 1 part stain. I applied 3 coats. After spraying the concrete with ammonia to level out the acid I scrubbed it again. Then applied a coat of sealant.
