A ready mix supplier as submitted a tilt-up concrete mix that will provide a PH of about 12.5 to 13.
The painting sub-contractor will not warranty his work for a PH above 10.
Any suggestions from the tilt-up experts out there as to what admixtures or cementitious substitutes could be used to reduce the mix PH or a paint product that is not susceptible to concrete PH above 10?
