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.
