yes, It will make the new concrete have a better bond to the old. My late father-in-law was a plasterer and brick layer by trade. About 30 years ago he and my dad patched some church steps. They really should have been replaced but the church did not have the funds. Well he used a bonding agent. They first cleaned the steps of loose cement. Then painted the thick whitestuff on the old concrete and waited over night before pouring the patches. As I said that was about 30 years ago and the steps are still in pretty good shape. I wish that I had his old file box, it had about 100 recipes for different mixes of plaster and concrete. ----- Original Message ----- From: "Lee A.
