Nitoseal PU40 is one part, low modulus gun-grade elastomeric sealant based on polyurethane technology. Nitoseal PU40 may be applied to joints between 5 and 35mm 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 35mm, please contact your local Fosroc Technical Service Department.
