The pH level of a concrete substrate, whether too high or too low, will also effect the overall system adhesion or bond strength. The ideal pH value for applying a polymer system is 7, although 6.5 to 9.9 is acceptable and is necessary for obtaining optimum adhesion. When the pH level is 10 or higher, acid etching is required, and when the pH value falls below 6.5, a caustic etch will be required.
