If your toilet "rocks" thereby breaking its seal, follow this simple solution: After throughly cleaning the toilet flange and bottom of toilet, apply new wax ring (to dry flange) and re-set and bolt toilet. Shim around toilet base with metal washers or plastic shims (make sure washers do not stick out beyond toilet base and /or trim plastic shims). Mix up some polymer modified, sanded tile grout using as little water as possible so that when you squeeze a chunk of it in your hand it holds its shape.
Chink this material around toilet base and wipe off excess with a damp sponge. This "dry pack" material will not shrink and your toilet will be as steady as a rock.
