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.
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
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.
