3mm Damp Proof Mesh Membrane - 40m²
PermaSEAL 3 Mesh Membrane is a high quality meshed membrane, designed for damp proofing walls internally above ground. Once the underlying damp issue is resolved, it creates a physical barrier to prevent further damage and salt contamination. The mesh provides an excellent key for a range of finishes.
Mesh Membrane for Damp Walls
PermaSEAL 3 is the ideal mesh membrane for damp walls. It is specifically designed to be applied to damp walls to isolate them from new finishes. PermaSEAL wall mesh membranes are impervious to moisture and moisture vapour. This means they create a barrier between the old surface and your new finish. This effectively isolates damp walls and prevents any new salt deposits on the surface plaster and damage to decoration.
Salt Contaminated Walls and Damp Proofing
PermaSEAL 3 Mesh membrane is the ideal product for isolating salt contaminated surfaces. These surfaces can often appear damp in periods of high humidity. The hygroscopic salts that are contained in the surface attract the damp in the air to the surface giving the appearance of a darker, damp patch. This is often misdiagnosed as penetrating or rising damp. The membrane simply isolates the background contaminated substrate from the new finish alleviating any signs of damp.
Uses of PermaSEAL 3 Mesh Membrane
- Damp proof mesh membrane above the ground internally
- Isolation membrane for salt contaminated surfaces
If you are suffering from high salt tides, we stock a 1.2 metre mesh membrane.
Benefits of PermaSEAL 3 Mesh
The PermaSEAL 3 is highly resistant to water, alkalis, and saline solutions, and is guaranteed against deterioration for 30 years. It also provides the following key benefits:
3mm Stud Profile
Having a 3mm stud means that PermaSEAL 3 mesh damp proofing membrane only has an overall thickness of 3.5mm. This makes it the preferred meshed membrane when space is at a premium.
PermaSEAL 3 Mesh has an integrated high quality meshed surface which provides an excellent key for lime mortars, renders, plasters or dabbed plasterboard.
Installing a mesh membrane
The mesh membrane installation is straightforward. Once the underlying damp issue has been resolved, you can simply apply the mesh membrane to the wall in the following way:
- Clean the substrate to obtain as flat a surface as possible. Remove any damaged, loose or crumbling plaster.
- Cut the membrane to size with a sharp knife or scissors.
- Fix the 3mm membrane (with the mesh facing outward) to the surface with plugs. It can be fitted horizontally or vertically.
Jointing - The 3mm mesh membrane can be easily bent around corners as it is a very flexible material. Alternatively, it can be butt jointed and sealed with PermaSEAL Fleece Overstrip.
Finishing - Plasterboard panels can be fixed to the membrane by the dot and dab method (minimum of 50% board coverage with the dab adhesive), giving a dry surface ready for immediate decoration.
