Description

Polyurethane Sealant Nitoseal PU50 is a single-component, non-sag, medium modulus, moisture-cure, polyurethane hybrid joint sealant. It is formulated with a unique silage-terminated polyurethane polymer, that provides unequaled performance against standalone polyurethane sealants.Polyurethane Sealant Nitoseal PU50 is an extremely durable sealant in dynamic joints, offering persistent adhesion once fully cured. Polyurethane Sealant Nitoseal PU50 may be applied to joints between 5 and 50mm wide. To minimize stress imposed on the joint sealant, all moving joints should be designed to an optimum width to depth ratio of 2:1 with an overriding minimum depth of 5mm for non-porous surfaces and 10mm for porous surfaces.For joint widths exceeding 50mm, please contact Fortimix BD Consturction Technical Service Department.

Joint surfaces must be clean, dry and free from frost. Remove 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. When resealing, the existing sealant should be removed from the joint and the arras 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, Backing rod or Expandafoam. For construction or contraction joints a bond breaker tape or back-up strip must be used.Where a particularly neat finish is required, mask the face edges of the joint before sealing and remove immediately after tooling is completed.
