Platon PB2 MESH Damp Proof Membrane Kit (With Sealing MASTIC)

Platon PB2 Mesh Damp Proof Membrane is a thin, 2mm Stud, cavity membrane developed specifically for use when Damp Proofing above ground walls subject to Rising Damp, Penetrating Damp or Salt Contamination.

Platon PB2 Mesh Membrane can be finished with plaster, render or plasterboard bonded using adhesive dabs.

Unlike wet or liquid applied forms of ‘tanking’, Platon PB2 Mesh Membrane 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 Platon PB2 Mesh Membrane is significantly less than for other methods.

Typical Applications:

Platon PB2 Mesh Membrane 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.

Platon PB2 Mesh Membrane is ideal for:

  • Barn or Mill Conversions

  • Thick Random Stone Walls

  • Contaminated chimney breasts

  • Listed Buildings

  • After a Chemical Damp Proof Course (Cream or Fluid).

The Damp Proof 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.

Platon PB2 Mesh Membrane can be used in conjunction with other membranes and is particularly useful for lining window and door reveals where intrusion into the opening must be minimised.

Platon PB2 Mesh Membrane is tough but pliable and is easily formed around internal and external corners.

When laying new solid floors, apply Platon PB2 Mesh Membrane to the walls first, then lap the floor DPM up in front of the membrane. Seal as required and trim the DPM flush with the top of the finished floor.

Platon PB2 Mesh Membrane is suitable for internal use only.

Installation Method:

Platon PB2 Mesh Membrane is suitable for damp-proofing purposes only.

Remove loose and soft plaster/render, wallpapers and embedded timbers. Dub out voids, hollows and loose areas of masonry using a cement mortar.

Offer up the membrane and fix in place using the Fixing Plugs and Sealing Mastic, supplied in the kit.

Pull the membrane as tightly as possible against the structure to minimise hollow areas behind as these can interfere with the application of plaster or plasterboard.

Fit the membrane tightly into and around corners, again to avoid damage when applying finishes.

Use 16 fixings per square metre, spaced out in a regular ‘diamond’ pattern.

Adjacent pieces of Platon PB2 Mesh Membrane are butted together (an overlap is not necessary), and sealed over with Platinum Mesh Tape (Sold Separately).


Tarmac Whitewall high impact plaster, sand and cement render (6:1 with SBR or 6:1:1 with hydrated lime) or renovating plaster are all suitable wet applied finishes. A minimum of two coats should be applied.

The initial ‘scratch’ coat should be well worked into the mesh facing, the minimum thickness should be 6mm. Allow to cure for 7-10 days before applying subsequent coats. Do not allow the plaster or render to dry out too quickly or cracking may occur.

Apply no more than a total of 15mm of render or plaster. Plasterboard can be bonded using regular ‘dab’ adhesive or Low Expansion Polyurethane Foam Adhesive (See Soudabond Easy). Apply the adhesive over the heads of the fixing plugs and ensure that 50% of the membrane area is also covered. This ensures that direct ‘through’ contact is made between the plasterboard and the masonry substrate.

Plasterboard fixed in this way can be skimmed the next day and painted or wallpapered a few days after that.

Drying times are very much reduced when compared to ‘wet’ systems.
