Typical Uses

Substrate Preparation

  • Existing plaster, render or screed should be removed to level surfaces, preferably with Wykamol’s Universal Mortar.
  • Walls suffering from mould or masonry fungi should be brushed clean and treated with Microtech Biocide before the membrane is installed.
  • Dry rot in walls necessitates a detailed assessment before application.

Application

  • Fixing requires Wykamol CM Plaster Plugs or Brick Plugs, with the studs facing the wall.
  • In above-ground applications, the membranes should be sealed by butt jointing and oversealing with Wykamol Fibre Tape.

Finishing and Aftercare

  • The membrane can be finished using standard plastering techniques or dry-lining.
  • Normal decorating materials can be used as soon as the floor, screed or plaster finishes are dry.
  • A mechanical ventilation system is recommended for areas that lack natural ventilation to control condensation.
