Wykamol CM3 MESH Damp Proof Membrane (3mm Stud)

Wykamol CM3 MESH Membrane is a High Quality, 3mm Stud, Damp Proof Meshed Membrane comprising of HDPE Membrane with a rot-proof HDPE mesh on the surface of one side, perfect for damp proofing. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.

  Wykamol CM3 MESH Membrane is supported by BBA Certification Certificate Number 18/5595.

Wykamol CM3 MESH Membrane is available in 1.0 Metre, 1.2 Metre and 2.0 Metre Widths.

Available in various Roll sizes ranging from 2.5M² to 40M².

Wykamol CM3 MESH Damp Proof Membrane

Wykamol CM3 MESH Membrane is a composite damp proof membrane comprising of HDPE membrane with a rot-proof HDPE 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 & dab plasterboard.

Wykamol CM3 MESH Membrane is 0.5mm thick and has a pattern of raised 3mm studs. The studs face the wall and create air channels that allow for vapour equalisation to take place between the membrane and the wall.

Wykamol CM3 MESH Membrane is light, clean and easy to handle. It can be cut with a sharp knife, scissors or shears. The membrane is inert and is highly resistant to water, alkalies, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.

Wykamol CM3 MESH Membrane is guaranteed against deterioration for 30 years and has a life expectancy of at least 50 years.

Benefits & Features:

  • BBA Approved

  • 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

  • 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

Preparation:

Clean the substrate to remove all loose debris and organic matter. Plaster should be removed as it can soften over time, which will weaken the fix of the membrane to the wall. If the wall render is in good condition, it does not have to be removed and the Wykamol CM3 MESH Membrane can be fitted directly over. If the render is damaged, local repairs may be required

Loose or crumbling render should be removed and local repairs made. If the render is in very poor condition, all of it may need to be removed

Obtain as flat a surface as possible. If the wall is undulating, better results are produced if the wall surface is dubbed-out flat with sand & cement prior to installation of the membrane, rather than dubbing out over the top of Wykamol CM3 MESH Membrane. A flat, uniform surface to the substrate means that the plaster or render above Wykamol CM3 MESH Membrane will also be uniform and less li
