Newton 803 Newtonite is specifically designed for application after the insertion of a new damp proof course in space sensitive areas.

Meshed Damp Proofing Membrane

Newton 803 Newtonite is specifically designed for application after the insertion of a new damp proof course. Newton 803 Newtonite provides a firm key and impermeable barrier on any damp or deteriorating surface. The membrane can be installed straight after the insertion of the new damp proof course and can be rendered or dot and dabbed immediately after completion of the membrane installation. This cuts down the time of the remedial work.

Installing a Mesh Membrane

Once the new damp proof course has been injected, simply apply Newton 803 Newtonite to the walls affected then either dot and dab or render directly to the Newton 803 Newtonite. The Newton 803 Newtonite presents a physical barrier between the old surface finish and the new internal finish. This prevents any future discolouration and salt deposits on the surface plaster and decoration. The 3mm profile means it can be used in space sensitive areas.
