Concrete Stain. in/Outdoor. Industrial-Quality. Eco-Friendly. 19 Colors/3 Sizes. Order Color Sample First. (1/2 gal Emerald)

I accidentally ordered two samples of the same color, but it seems the color is good for my project. Here's what I learned. I'm not sure the larger size will be more concentrated than the sample. The sample was diluted and ready to use. I ordered dark walnut and when I opened it, it looked like dark gray. My project area is a front porch less than 100sf that has both light gray flagstone with touches of brown. I tested it in an inconspicuous small dry area using a foam brush and the color was brown. So we cleaned the area and while still damp, I applied some. It went on like a light chocolate milk color and then didn't seem to do anything. So I dried the area with a towel and gave it little time to dry, then I applied to the entire area using a roller brush. It did darken as it dried. Lesson learned - the foam brush or anything that puts the stain on evenly is the way to go. The streak areas where there is more product is brown and is the color I wanted. I will either spray or use a foam brush. The other areas changed color slightly. I am now awaiting the 1/2 gallon product and will report back with pictures of how it turns out.Update: I received the 1/2 gallon today and immediately applied it. I used a sponge brush and applied it evenly. It is great. Attached are the pictures. The stain itself looks gray to me even after shaking/mixing it extensively, but it dries to a brown color. The pictures represent about 3 coats including the samples I received and today's 3rd coat. The final picture was taken within an hour and it likely will darken more. The original stone was a gray color with some brown in some of the stone.

I love it. It made finishing our basement bathroom floor easy. The hardest thing for this old grandma to do was to get down on the floor to mark the striping tape. It is not perfect but I'm fine with it. I bought some expensive striping tape from the auto parts store it worked too well but it only covered about a third of the floor. There is striping frog tape but I tediously cut a smaller strip from the tape I had. Then, I poured the charcoal grey concrete stain into a spray bottle and sprayed the finer mist generously over all of the floor. Then, I put the setting for bigger drops that I spattered around. When that dried, I used a small amount of the white concrete stain and using a small paint brush did the veining, highlighting existing veins and creating more veins. The veining was so easy gliding over the previously stained floor. Then pulled up the tape. It leaked a little under the frog tape, but I happen to like that the best. It looked great but I did go over it all with a clear sealer. JUST A NOTE: This work was done on a never before sealed section of a 1936 basement floor that was cut out and new concrete section poured meeting the old concrete. The striping is more faded on the old concrete that was done with a similiar technique a couple of years ago, but is still visible.

Definitely not the color in the picture. Looked like grey milky water. Didn't look brown or spray on brown. It also didn't even dry a brownish tint. Plus if you order samples it could come from a different batch then your gallon they send you.I have bought the black color twice and had really good results both times.

We were using airstone products to create a stone look around our new fireplace. Their product comes in several different color groups, and each has 4 colors. Unfortunately, you receivew fewer stones in certain colors, which can make it more difficult to create the combinations of stones you want for the wall. Instead of ordering more boxes of stones, I decided to look into paint/stain options. I experimented with these acid colors a little and they worked pretty well with the airstone. You definitely have to practice a little on different stones to see how it will turn out. These were not exact color matches (I didn't expect them to be), but the sample size was more than enough to treat a sufficient number of the stones to blend in nicely. The sample sizes should provide more than enough to get a good idea of what it would look like if you needed to stain a much larger area of concrete. I definitely recommend trying this if you want to color concrete or stone.

We had curbing put in with a color added. It was really splotchy as though some looked dry and some wet and darker. Was not mixed oroperly. This stain solved our problem. Love the black curbing now in the yard. Looks neat and clean and covered all the mistakes. Wonderful product.

I purchased the Terra Cotta stain (sample) to refinish a natural (light gray) concrete wall fountain. As you can see in the photo, it cam out more of a caramel/tan than terra cotta. No reddish/orange hues at all.I will try using a red shade of stain to at least get some highlights, Easy to apply and clean up.

Gave a nice cover on my concrete pieces. Love the final product

I bought this product to refinish a small concrete fountain. It was covered with white hard water stains. I removed as much of the hard water marks as I could and used the concrete stain. It covered amazingly well, even over the white stain I could not get off. I will probably put a second coat on some of the spots. I am also going to fill the finished fountain with distilled water next time, to prevent the hard water stains from coming back.I would recommend this product.
