Newtonite Lath Mesh Membrane - 3 mm Meshed Damp Proofing Membrane
Verified by manufacturer 4 months ago
Meshed damp proofing membrane.
Application
Can be used as a damp proof base for renders, plasters or dot and dab plasterboard and a damp proofing system to deal with rising damp.
Suitable for wall finishes including:
- Plaster.
- Render.
- Hydraulic lime.
- Plasterboard bonded to the membrane with a propriety adhesive compound.
Description
BBA certified damp proof 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.
Features and 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.
