Platinum Building Chemicals Ltd | Damp Proof Membrane Kit
A range of Damp Proof Membrane Kits using Platinum PM3 NON-MESH Membrane as the choice of Damp Proof Membrane.
These Damp Proof Membrane Kits can be purchased in two sizes, 20M² and 40M². Use the drop-down box option below to choose your preferred kit size.
The Platinum PM3 NON-MESH Damp Proof Membrane Kit is supplied with a roll of PM3 Damp Proof Membrane, the required number of Fixing Plugs and a roll of Overtape for jointing. An SDS Drill Bit (10mm x 160mm) is also supplied with the kit.
A full table of each Damp Proof Membrane Kit Contents is shown below in the 'Description' Tab.
Read our Guide on 'How To Identify & Treat Rising Dampness On Walls' and 'How To Install a Damp Proof Membrane'.
Platinum PM3 Damp Proof Membrane is a High Quality, 3mm Studded, NON-MESHED, HDPE Membrane suitable for the Damp Proofing of Walls, Floors, Vaults and Tunnels.
Platinum PM3 Damp Proof Membrane can be used as an alternative to meshed membranes where a meshed surface is not required, typically where the wall finish to the damp proof membrane is timber battens, a dry-lining frame or block wall.
Platinum PM3 Damp Proof Membrane is guaranteed against deterioration for 30 years and has a life expectancy of at least 50 years.
Note: The Fixing Plugs supplied in this kit are our Platinum Waterseal Brick Plugs. The Sealing Tape supplied is our Platinum Corner Tape.
Does not require extensive and damaging preparation to the wall surface.
Only 3mm in thickness and so is ideal for when space is tight, such as with stairs or low headroom.
Speed of installation.
Provides vapour control and, when used with humidity control systems, is capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2009 and NHBC Chapter 5.4.
Creates a dry, habitable living space in areas previously suffering from damp / wet conditions.
Waterproof, Salt Inhibiting, Root and Contaminate resistant.
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 Platinum PM3 Damp Proof Membrane can be fitted directly over. Loose or crumbling render should be removed.
If evidence of bacterial growth can be seen, use a fungicidal product prior to the fitting of the membrane.
If any evidence of wet rot or dry rot is seen, have it dealt with by a qualified remedial specialist.
If a new slab is to be laid as part of the works, it is preferable to fit Platinum PM3 Damp Proof Membrane prior to the laying of the floor slab with the floor DPM extending upwards in front of the Platinum PM3 Damp Proof Membrane ready for the concrete placement.
Platinum PM3 Damp Proof Membrane can be cut with a sharp utility knife, scissors or shears
Decide whether the membrane is to be fitted horizontally or vertically
Joints may be made horizontally or vertically.
Fit the edge of the next length of membrane adjacent to the previous sheet with a butt-joint. Overtape the butt-joint with Platinum Corner Tape.
Platinum PM3 Damp Proof Membrane can be taken round corners. Try to fit the membrane square with neat creases to the internal and external corners. Where the membrane starts to be misshapen due to the contours of the wall, cut the membrane and start again with a new butt-joint secured with Platinum Corner Tape.
In cold and damp conditions a heat gun should be used to gently evaporate surface moisture prior to the application of the Platinum Corner Strip.
Cut the membrane to size. Ideally, Platinum PM3 Damp Proof Membrane should be continued up into ceiling voids and down past the slab to the oversite. If this is not possible, cut the membrane so that it finishes tightly to the soffit and floor finish. A gap is not required at the soffit or floor, indeed the system works more efficiently when the system is not ventilated as this impedes the natural vapour drive from inside the property to the outside that still continues through the membrane.
Platinum PM3 Damp Proof Membrane is fitted to the wall with the studs facing the wall and the flat surface facing inwards towards the applicator. Fix the membrane to the wall with the Platinum Waterseal Brick Plugs to all substrates except to slightly friable mortar substrate, when the Platinum Cob Plugs should be used.
Platinum PM3 Damp Proof Membrane can be fitted horizontally or vertically. Fit the membrane as level as possible - best results are achieved when a long builders level or a rotating laser level is used.
Using the 10mm Drill Bit, drill through the membrane into the wall to a depth of at least 60mm.
Fix only as many plugs as are required to fix the membrane neatly to the wall
If fixings are required for fixing of timber battens, brackets for Gypliner type dry-lining frame or wall ties, add further plugs to the correct centres required for the wall lining.
Hammer the plugs home using a wide headed hammer such as a lump hammer or mallet.
Fit Platinum PM3 Damp Proof Membrane to return walls to isolate wall finishes from dampness transmitting from the main wall being treated.
Platinum PM3 Damp Proof Membrane can be taken into reveals.
Platinum Waterseal Brick Plugs have a hollow core that is designed to receive 5mm self-tapping screws. Use either plug to secure timber battens or locating brackets from wall lining systems. Heavier items can be supported by screwing a piece of chipboard to the plugs at fairly close centres and then fixing the heavier item to the chipboard in a conventional way
Heavier objects should be attached to the wall using resin anchors. Seal around the resin anchor with Newton 801-M Mastic Sealant.
