A plastering guide (10) for an electrical socket or switch backbox comprises a guide body (12) which is shaped to closely fit and project from a single or multiple gang electrical backbox (20) positioned in a cavity (38) in a wall (40). In use, the close fit of one or more sides (18) of the guide body (12) with the backbox (20) prevents or limits the ingress of wet plaster (48) into the backbox (20). A method is also provided.
