Concrete Acid Stain | Dark Walnut 1 Gallon

So I did an overlay with a concrete countertop and used this acid stain. It turns yellow when you apply it. But then it quickly changes to brown. The first time I sprayed it I just used the full concentrate and it made my countertop a dark walnut brown. But then I played with it and watered it down and the color was a light choclolately brown. It was gorgeous. A little of this product goes a long way. I only used about a quarter of a gallon for 2 10 foot countertops and one smaller one. The first time I painted it on and there were some brush marks. The second time I watered it down and put it in a spray bottle. Pros High quality. A little goes a long way. Beautiful color Cons It will stain everything in sight and it is difficult to remove. But it is a "stain" so prepare your surfaces accordingly.

I have used another brand of concrete acid coloring for years that worked great. I decided to try a new brond as I wanted the Dark Walnut Color. It turned the concrete a faint light green. I would never buy this product again. Note that you can't return this product.

Nice color for my project.

This was my fourth bottle of this stain. I actually ordered two bottles in this last purchase. The first bottle did fine just like the bottle prior the second bottle, however, actually started smoking on the concrete and had a bad odor when we came back out the next morning to check the concrete that has been staying with the second bottle, it was completely white stain unlike the other bottle. Now I gotta figure out what I can safely put on the concrete to re-stain it if possible! I tried reaching out to the seller through Amazon, but it’s complicated task as this has a no return policy. I don’t want return. I want another bottle correctly mixed to put on the concrete.

I could do better with concentrated tea. Product is not color indicated (dark walnut) and BARELY colors the grey of the concrete. Two hours later, it washes off as if it were never applied. REALLY disappointed!

They ship it quick, so you can finish your project.

I've used this product numerous times, all throughout our house, the garage and and outdoor pavilion. The most recent application was the concrete in front of our garage. For some reason, this time it faded to almost nothing and looks like I didn't put any stain down whatsoever. Has anyone seen this? I'm hoping when I rinse it tomorrow and seal it the next day that the color comes out. As for now, I'm perplexed...
