With the waterproof backing paper uppermost, the SK Bearing is laid in one operation on the previously cleaned upper surface of the supporting wall. Care should be taken when slabs are being poured in situ to ensure that the complete supporting surface is covered by the SK Bearing and its expanded polystyrene surround. If an adhesive is used it should be a non-solvent type. Additional details are available in our brochure and in the relevant fitting instructions sheet.
