Thanks buddy, wiping off the excess depends on how quick it goes of on the tile if it goes to quick just keep running a slightly dampened sponge over to tiles being careful not to wash the grout away and each time clean the sponge of the excess and when the grout is touch dry you can start buffing up. Hope this helps.
