H&C Concrete Ready Phosphoric Etching Solution
H&C Concreteready Phosphoric Etching Solution is a clear liquid containing phosphoric acid, which opens the pores in the concrete and allows the stains and sealers to bond to the concrete surface. It is ideal for both indoor and outdoor applications and helps to remove efflorescence. The etching solution also lowers the pH level of new concrete and mortar joints, improving the bond between the coating and the concrete.
To begin the etching process, mix a solution of three parts acid to one part water. Pour the mixture onto a section of the concrete and allow it to sit for ten to fifteen minutes. The solution will fizz and bubble during this process. It is important not to allow the concrete to dry. If it does, add more acid to the solution.
The etching process should be repeated as needed. It should leave a rough texture similar to 120-grit sandpaper. If the concrete surface becomes too smooth, re-etching may be necessary. Then, re-apply H&C CONCRETEREADY ETCHING SOLUTION.
H&C Concrete Ready Phosphoric is an excellent solution for removing oil stains from concrete surfaces. It bonds to most concrete surfaces and is compatible with most paints. It is also highly resistant to solvents, making it a great choice for cleaning concrete floors and driveways.
The acid etching solution must be rinsed thoroughly before use. A broom or squeegee should be used to collect the rinse water. The acid etching solution should then be disposed of properly. In some cases, you may be able to pour the acid etching solution down a drain. However, it is important to check local regulations before using it.
H&C Concrete Ready Phosphoric Etching Solution is available in two different concentrations. One gallon of the solution is sufficient to cover about 100 to 150 square feet. It dries within an hour depending on the type of concrete and its porosity.
The H&C SHIELD-CRETE WATER-BASED EPOXY GARAGE FLOOR COATING is an easy way to give a professional-looking concrete floor. The solution is easy to apply and comes with a colorant, activator, and slip-resistant additives.
