Damp Proof Membrane Kit - 10m²
Our damp proof membrane kit contains all you need to damp proof walls internally above ground. Once the underlying damp issue is resolved, the high quality 3mm mesh membrane creates a physical barrier to prevent further damage and salt contamination.
The PermaSEAL 3 plaster membrane included in the kit provides an excellent key for a range of finishes. It can be rendered or dot and dabbed immediately after installation. This significantly cuts down the time of the remedial work.
The Damp Proofing Membrane Kit includes:
1 x Roll of PermaSEAL 1m x 10m 3mm Meshed Membrane (10m²)
200 x PermaSEAL Plaster Plugs 60mm
200 x PermaSEAL Sealing washers
1 x 7mm Masonry Drill bit
Membrane Kits for Damp Walls
The PermaSEAL 3 mesh membrane kit is ideal for damp walls. It is specifically designed to be applied to damp walls to isolate them from new finishes. The membrane kit’s PermaSEAL 3 mesh membrane is 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.
Damp Proof Membrane Installation
The mesh membrane installation is straightforward. Once the underlying damp issue has been resolved or a new injection damp proof course has been installed, you can simply apply the mesh membrane to the wall. Follow these steps:
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.
