Technical Information

Nitoseal® MB175 is a flexible rubber-bitumen joint sealant with excellent slump resistance. Nitoseal® MB175 stiffens to form a firm seal after application. Atack free surface will form within 1 or 2 days depending upon the conditions of exposure and ventilation, however the nature of bitumen means a slight ‘sticky’ feel will persist.

Where To Use

  • For sealing joints in flashings, guttering and sheet laps
  •  An integral part of the Proofex waterproofing system


  •  Firm flexible weather resistant seal
  •  Excellent slump resistance
  •  Excellent immersed adhesion
  •  Compatible with asphalt or bituminous surfaces
  •  Unaffected by alkalis or sulphates
  •  Easily gunned
  •  Suitable for joints up to 40 mm wide
