Application

Newton 801 Mastic is typically used to...


  • Seal fixing plugs to Damp Proofing Membranes, including Newtonite 803, Newtonite 803 Mesh Membrane, and NewLath 805 Mesh Membrane.
  • For sealing around service penetrations and protrusions through the substrate/membrane.
  • As a general, high performance and multipurpose sealant in the building industry.

Description

A multipurpose silicone sealant primarily used with the NewLath 805 Mesh Membrane and Newtonite 803 Membranes – applied to the plug before fixing into the membrane, 801 Mastic seals the penetration and prevents bridging between the damp substrate and new internal surface.


Applied to the fixing plugs before they are fitted, Newtonite 801 Mastic serves so as to seal the penetration and stop the occurrence of a ‘bridge’ between the damp or stained substrate and the new internal surface. Newtonite 801 Mastic has a high resistance to both ageing and extremes of temperature, as well as achieving a high adhesive strength, without primer, on the majority of materials used in the building and engineering industries.


Features and benefits:

  • Prevents efflorescent salts and staining to the finished surface.
  • Seals the fixing plug to the membrane.
  • Obtains a high adhesive strength without a primer.
  • Applicable to most materials used in the building and engineering industries, including, but not limited to laminated and double glass, aluminium, steel, stainless steel, anodized steel, treated wood, and polyvinyl chloride (PVC).
  • Also compatible with alkali substrates such as concrete and brick.
  • Applicable in temperatures as high as 150°C and as low as -50°C.
  • High resistance to ageing.
  • Non-toxic.
  • Solvent-free.
  • 25 cartridges of 310 ml per box.
