we are replacing several bullnose coping pieces around a 1980 gunite/1999 fiberglass interior pool. There is minor deterioration to the beam. We removed old several old coping pieces and chiseled out the 'hollow' concrete mortar from the last repair... the expansion joint was also filled in with mortar, dug that out. Today renting concrete saw to eliminate source of problem - random areas where concrete deck butts up to coping without expansion joint.
tomorrow or Monday plan on resetting coping. Was told to use 'white concrete'. One part white cement, 2 parts white sand. I cant find internet confirmation of that formula. I find 1/2 part limestone, 1 part cement, 3 parts sand... but they are not talking about the same situation.
It seems most coping questions aren't real popular. Can anyone help?
