Q. - How comfortable we could be to obtain a good looking gym with the acid stain as I read it may not give the same color everywhere. Will the result be better by using professionals to do it? Thanks.
Hello Marc
A. - Acid stain works by chemically reacting with the minerals that are allready present in your concrete. So regardless of who applies it, it is going to be the color it's going to be. Pro's will have experience, technique and expertise unique to each one, so I can't say that a pro wouldn't be a better option to achieve the exact look that you're after, but I can say that you can certainly stain your own concrete with confidence and great results.
In regards to how well it will work in your particlar situation... There's no product in existence that works out perfectly 100% of the time for 100% of users. There's just too many variables in the real world. Acid stain however, is always the best route with concrete. If you're in the 99+% that it works great for, then you have an awesome looking concrete surface with extremely low maintenance and you did it on the cheap. If you're in the less than 1% that staining concrete doesn't work out for, then you can still cover it however you like as acid staining doesn't get in the way of other products, and you didn't spend a bundle on something that was worth a try but didn't pan out.
I hope this helps,
Earl
