Lime, cork and clay based insulating plaster

Diasen Diathonite Deumix Plus

Main purpose

Restoration and moisture management of walls affected by rising damp and salt deposits. Also to speed up drying of residual moisture in the wall after treatment for damp.

Use it on

Internal or external solid stone or masonry walls where rising damp and salt deposits can occur.

Overview

Diathonite Deumix+ is a robust thermal insulating plaster and salt inhibitor made from natural Hydrated lime, NHL 5 binder, Clay, Cork and Diatomaceous earth. It is breathable and capillary active with excellent insulation properties.

This plaster is ideally suitable for masonry walls where high levels of moisture, rising damp and salt deposits are problematic. Deumix+ effectively deals with excess moisture in the wall, regulates humidity and helps prevent salt deposits.

Where to use it

Deumix+ plaster can be used on solid stone or masonry walls either internally or externally. Suitable walls are typically those where rising damp, external rain, condensation, excess moisture or salt deposits (efflorescence) are present. It is also ideal to be applied on top of Watstop tanking plaster in basements where some or all of the wall is underground. It is mainly used in the restoration and thermal insulation of damp masonry walls especially in older or historic/listed buildings. It can also greatly speed up the drying of walls that have recently had a damp treatment so any residual dampness can dry as quickly as possible. It can also be used to level uneven walls before installing Gutex Thermoroom wood fibre insulation or Calsitherm Climate Boards. When used as the only plaster for the wall, it should always be covered with Argatherm finishing plaster. Before you start your project, it is essential to investigate and fix any existing damp or moisture related issues in the wall; please see our installation guide for full details. For optimal performance and longevity of any internal wall insulation system, it is crucial to evaluate the suitability of the wall and rectify any problems before installation begins. Please read our guide: “How to prepare traditional solid walls for IWI Installation” to ensure you achieve the best results.

What it does

Diathonite Deumix+ readily absorbs moisture from the wall to help regulate and deal with rising damp. It’s breathable and capillary active properties transport excess moisture or dampness rapidly out of the wall to the surface where it quickly and harmlessly evaporates. The excellent thermal insulation and moisture control abilities effectively prevent condensation and subsequent mould growth.

Why we love it

Diathonite Deumix+ is made from natural materials: Hydrated lime, NHL 5 binder, Clay, Cork and diatomaceous earth. NHL5 is a strong and more robust type of lime. These breathable materials are highly porous and capillary active and work together to absorb and release moisture and humidity without being damaged. They provide thermal insulation and sound insulation, prevent condensation/mould, and form a robust yet elastic (non-cracking) wall plaster. It also contains a salt inhibitor to prevent deposits of salt occurring on the wall. Coverage for 20mm thick layer (on level, smooth walls): Hand applied: approximately 10.00kg per square metre. Each bag covers 2 square metres. Sprayed on by machine: approximately 8.80kg per square metre. Each bag covers 2.27 square metres.

Features

  • Capillary active & breathable
  • Prevents salt deposits (efflorescence)
  • Insulator
  • Suitable for uneven walls
  • Used on whole wall or effected areas only
  • Non combustible

Benefits

  • Robust and durable in problematic walls such as cellars, basements or walls affected by poor drainage or severe weather cycles.
  • Allows moisture caused by rising damp to pass through the wall helping it to dry out.
  • Prevents unsightly salt stains and manages moisture by applying a minimum thickness of 25mm.
  • Ensures full compatibility with other breathable solutions used on the wall, so ideal for heritage buildings.
  • Provides thermal insulation to the wall, keeping you warm and reducing energy bills.
  • Spray or trowel applied, no special training required.
