How To Remove Rusts Stains From Concrete

In this project a marina in Baltimore had been searching for the solution to how to remove rust stains from concrete. In this case it was a lot more than rust stains.

The concrete had years of mold, alage, rust and other contaminents that turned the concrete black.  Over time the marina had tried many remedies but to no avail, nothing worked. Finally they brought in various contractors and tested different methods and solutions.

The solution to how to remove rust stains from concrete was finally achieved with a gelled acid developed by Surface Gel Tek of Mesa Arizona. It turns out that cleaning rust stains, mold and algae is a simple process using the gelled acid. Acids actually work to remove rust stains and algae from concrete but they settle back into the concrete immediately. To effectively clean concrete with acid requires tremendous labor and a lot of acid.

Gelled acid solve the problem. When the gelled acid is applied and left to sit for 15 minutes the rust and algae comes free from the concrete but is contained in the gel. Now the gel can be easily cleaned and removed along with the rust and algae and if you get on your hands and clothes not a problem. The strongest, HD 24, is only 24% acid.

As you can see in the photo it works. 40,000 square feet was cleaned like new. Plus the fact that the Surface Gel Tek Gelled Acid is ASTM (American Society of Testing Methods) certified and is water soluable and considered a green product.
