Description

Damp Proof Mesh Membrane for High Salt Bands

PermaSEAL 3 Mesh Membrane is a high quality mesh faced cavity drain membrane for internal damp proofing and for application onto substrates that are contaminated with hygroscopic salts. With a height of 1.2 metres, it is taller than the standard mesh membrane. This means it can effectively deal with high tide marks caused by salts from rising damp. It is also more convenient for use on salt contaminated surfaces such as chimney breasts.

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 including dot and dab plaster board or direct rendering.

Mesh Membrane for Walls with High Salt Bands

PermaSEAL 3 is the ideal mesh membrane for damp walls with high salt bands. It is specifically designed to be applied to damp walls where tide marks are up to 900mm to isolate them from new finishes. PermaSEAL wall mesh membranes are impervious to moisture and salts. 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 new surface plaster and damage to decoration.

Salt Contaminated Walls and Damp Proofing

PermaSEAL 3 Mesh High Salt membrane is the ideal product for isolating salt contaminated surfaces where the salts are present up to the 900mm mark. 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 1.2 metre high mesh Membrane

  • Damp proof mesh membrane above the ground internally to overcome high salt bands or where it suits high walls
  • Isolation membrane for salt contaminated surfaces

Benefits of PermaSEAL 3 Mesh – High Salt Band Membrane

The PermaSEAL 3 Mesh Membrane 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.

Meshed Surface

PermaSEAL 3 Mesh has an integrated high quality meshed surface which provides an excellent key for lime mortars, renders, plasters or dabbed plasterboard.

We also stock a PermaSEAL High Salt Mesh Membrane kit that contains all you need to get the job done.

Installing a high salt tide line mesh membrane

The mesh membrane installation is straightforward. Once the underlying damp issue has been resolved, you can simply apply the meshed high salt tide membrane to the wall in the following way:

1. Clean the substrate to obtain as flat a surface as possible. Remove any damaged, loose or crumbling plaster.
2. Cut the membrane to size with a sharp knife or scissors.
3. 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.
