Triton Platon PB2 Mesh Membrane is a thin (PP) cavity membrane developed specifically for use when damp-proofing above ground walls subject to rising damp, penetrating damp or salt contamination.
PB2 Mesh can be finished with plaster, render or plasterboard bonded using adhesive dabs.
Unlike wet or liquid applied forms of ‘tanking’, PB2 Mesh can be worked on immediately after installation without waiting for drying or curing to occur.
The return to use time of walls damp-proofed using PB2 Mesh is significantly less than for other methods.
PB2 Mesh is unaffected by the presence of moisture or salts, making it ideal for use where conventional chemical injection damp-proofing and associated re-plastering might not work reliably or where penetrating dampness is the dominant problem.PB2 Mesh is ideal for:
- Barn or Mill Conversions
- Thick Random Stone Walls
- Contaminated chimney breasts
- Listed Buildings
- After chemical damp proofing.
The membrane can be applied to retained sound renders, brickwork, blockwork or stone, sometimes with minimal preparation when compared to waterproof rendering or ‘tanking’. Existing paint or lime-wash can be retained.
The quality and appearance of the applied finishes will be a direct reflection of the underlying substrate. Uneven, loose or soft stonework may need to be dubbed out to level off and stabilise the background.
Retaining sound cement render can be a good option if the substrate underneath is known to be in poor condition. Gypsum based plaster, wallpaper and any buried timber must be removed as these materials can deteriorate over time and in the presence of moisture.
PB2 Mesh can be used in conjunction with other Platon membranes and is particularly useful for lining window and door reveals where intrusion into the opening must be minimised.
PB2 Mesh is tough but pliable and is easily formed around internal and external corners.
When laying new solid floors, apply the PB2 Mesh to the walls first, then lap the floor dpm up in front of the Platon membrane. Seal as required and trim the dpm flush with the top of the finished floor.
PB2 Mesh is suitable for internal use only.
