HANDLING AND STORAGE
Care should be taken to ensure that the Lafarge ceiling tiles are not dropped or subjected to rough handling. Lafarge ceiling tiles should be stored in a dry area. The stacks must be packed on suitable timber supports, maximum 400mm apart and off the ground.
A level, clean, dry storage area must be made available for this purpose. Special care should be taken to ensure that the tile finish is not soiled or damaged during handling. Vinyl tiles can be cleaned with a mild detergent if necessary.
