Twistfix supplies its DIY damp proofing kit with everything needed for a do it yourself damp proof course to stop damp walls. The damp course injection cream offers a highly effective rising damp treatment.

DIY damp proofing kit has sufficient DPC cream to provide a new chemical damp proof course to 30m of single leaf wall (allow 15m for 9" or cavity walls).

The cream is formulated without thickening agents, using an emulsification process to produce a 100% effective damp proofing cream for use by DIY enthusiasts and Trade professionals. This pure DPC injection cream migrates fully and rapidly into pores in damp walls to form a chemical damp proof course treatment to stop rising damp.

Simply drill a 12mm hole, 90% though the wall at 100-120mm centres along the bed joint chosen for the DPC. Inject sufficient cream to fill the hole to within 1cm of wall surface and leave it to diffuse through the wall and cure to form a chemical damp proof course. Make good with sand and cement, whist cream is in the hole or with mastic if filling after diffusion.

DIY Damp Proofing Cream Kit includes:

  • 8 x 380ml cartridges of professional damp proof cream
  • 1 x 12mm x 160mm SDS carbide drill bit
  • 1 x 12mm x 250mm SDS carbide drill bit
  • 1 x Extension tube
  • 1 x  caulking gun
  • 1 x Pair of protective gloves

Consumption rate – 115mm wall = 3.8m / tube of DIY damp proofing cream
Consumption rate – 230mm wall = 1.9m / tube of DIY damp proofing cream
*Approximation only - allows 5-10% wastage

When damp proofing a solid wall then one can drill and inject from the most accessible side. When treating cavity walls the inner and outer walls should be treated separately, drilling and injecting the cream from both sides of the wall to form a damp proof course in each. Damp plaster should be renewed to complete the rising damp treatment.
