Polyurathane Sealant

Nitoseal PU40 is a 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 minimise 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.

Uses
Nitoseal PU40 is suitable for sealing joints in concrete, brickwork, blockwork,  precast  panels,  stone  cladding,  perimeter  sealing  around doors and windows, and non trafficked floor joints.
