Does anyone know the best cement mix for laying old pamments onto a level concrete screed floor. The pamments are very old red clay 9 x
9's and about 2 inch deep. Some have suggested using a weak cement mix and others suggest putting lime into the mix. It was even suggested to lay on a bed of sand. Also, should I use the same mix, whatever that is for the grout. Grateful for any views.Regards, Dick
