Mastics & Pastes

Mastics & Pastes

A range of self-supporting, non cracking cold-applied mastics, designed for the protection of mechanical pipe joints, flanges & valves, as well as sealing ducts and conduits against ingress of gas & water. These mastics & pastes are fast and easy to apply, with minimal surface preparation required. They conform, fill & seal awkward shapes/voids with ease. Denso Paste™ is a petrolatum based compound to be applied prior to the application of Denso Petrolatum Tapes (particularly Denso Tape™ as part of the Denso P1 System). The Denso Profiling Mastic™ is a self-supporting mastic for moulding around irregular shaped fittings (as part of the Denso P1 & P2 System). Find our more about the mastics & pastes below.
