Instructions for use

  • Preparation

Joint surfaces must be clean dry and free from all dirt, laitance, loose material and foreign matter. Remove all rust, scale and protective lacquers from metal surfaces. Removal can be achieved by rigorous wire brushing, grinding or grit blasting. Joints in concrete should preferably be sawn. After sawingall saw slurry must be flushed away and the joint allowed to dry. When resealing, the existing sealant should be removed from the joint and the arris cleaned back to sound clean concrete. All debris should be removed.
Any expansion joint filler must be checked to ensure it is tightly packed and no gaps or voids exist at the base of the sealing slot before positioning a bond breaker.The use of a bond breaker is not required in expansion joints containing cellular polyethylene joint filler such as Hydrocell XL*†.Where a particularly neat finish is required, mask the face edges of the joint before sealing and remove immediately after tooling is completed.
