Newton 803 Newtonite

3mm Meshed Damp Proofing Membrane

Newton 803 Newtonite is a composite damp proofing membrane, comprising of high density polyethylene membrane with a rot-proof polythene mesh that is heat-welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.

  • Key Benefits

    Provides a surface that is totally separated and unaffected by the dampness within the wall ensuring that the wall finish will never be affected by moisture or salts

    Superb ‘key’ for renders or plasters

    No need to use injected damp-proof courses which unnecessarily pump chemicals into the property

    Completely moisture resistant but allows vapour diffusion

    Quick and easy to install

    In many cases, the existing render can be left on the wall

    No requirement for damaging preparation to the wall surface

    Typical Applications

    As a damp-proof base for renders, plasters or dot & dab plasterboard

    As a damp-proofing system to deal with rising damp

    To protect exposed elevations against wind-driven rain

    An extenal plaster base for timber frame structures

    Newtonite presents a physical barrier between the old surface and the new internal finish. Unlike many systems it can be punctured when new wall fixings are required. Even poor and random substrates can easily receive Newtonite.
