Newton 805 Newlath
Application

Can be used as the following:

  • As a damp-proof base for renders, plasters or dot and dab plasterboard.
  • As a damp-proofing system to deal with rising damp.

Description

Newton 805 Newlath is an internally applied, composite damp proofing membrane comprising of a high-density polypropylene membrane with a rot-proof polythene mesh 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 and dab plasterboard.

Newton 805 Newlath is 1.5 mm thick and has a pattern of raised studs linked by reinforcing ribs. The 5 mm studs face the wall and create air channels that allow for vapour equalisation to take place between the membrane and the wall. The product is light, clean and easy to handle.

Guaranteed against deterioration for 30 years, has a life expectancy of at least 50 years.

Consult manufacturer's literature for relevant surface preparation information, for protection of the coating once applied and for recommended finishes.

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.
  • Provides a good ‘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.
  • It can be cut with a sharp knife, scissors or shears.
  • The membrane is inert and is highly resistant to water, alkalis, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.
  • The existing render can, in some cases, be left on the wall.
  • No requirement for damaging preparation to the wall surface.
  • Has a service life that can be equal to the design life of the structure.

Suitable substrates include:

  • Concrete.
  • Brick.
  • Concrete block.

Suitable for wall finishes including:

  • Plaster.
  • Render.
  • Hydraulic lime.
  • Plasterboard bonded to the membrane with a propriety adhesive compound.

Application:

Can be used as the following:

  • As a damp-proof base for renders, plasters or dot and dab plasterboard.
  • As a damp-proofing system to deal with rising damp.
