Damp Proofing Mesh Membrane Kit
Damp Proofing Mesh Membrane Kit with 2.5mm profile stud ideal for re-plastering after the installation of a chemical DPC or areas of damp such as chimney breasts.
The membrane made for HDPE material is impervious to salts and vapour and waterproof. The 2.5mm stud allows a wall to breathe behind the membrane. Suitable for a dot and dab plasterboard finish or you can render directly to it. Our recommended plaster finish is with the superb Renovating Plaster
Membrane should be applied tight to the wall with no ‘bubbles’ or kinks. For a dot and dab plasterboard finish fixings should be applied at 250mm centres. For a render finish and to avoid cracks in the render, centres should be reduced to 200mm centres.
Plaster board panels can be fixed to the membrane with the dot and dab method, giving a dry surface ready for immediate decoration. ‘Dabs’ should be applied to the heads of the Fixing Plugs, board edges and membrane to cover 50% of the membrane.
NOTE: We do not recommend that laminated or insulated plasterboard is dot and dabbed to meshed membranes. Laminated boards have to be fixed to the wall with a mechanical fixing at each side of the board, just above half way.
To avoid the passage of vapour or moisture to travel through the entry point of a plug fixing in the membrane it is advised plugs have a neoprene washer seal on them. Areas that are higher up a wall and not prone to damp my not necessarily require a seal but we do recommend there use.
Kits are available for both Dot and Dab or Render applications.
