Damp/Mouldy Walls

A1 Complete Builders have been recommended by Mr Phil Northey of Tecbuild to undertake some remedial works to a damp property.

Surface condensation is by far the most frequently encountered form of dampness in buildings and generally it is the most easily recognised with visual signs of mould grown in the main living room and solid walls construction. The temperature at which air can no longer hold excess water vapour is know as the Dew Point, surface condensation is thus formed when moist laden air comes into contact with cold surfaces which then becomes cooled. If cooled far enough it reaches the dew point temperature and the water vapour is released as condensation and associated black mould growth. Therefore, remedial works will have to be carried out IWI Insulation on living room walls (Isotherm or Marmox Board) and re-skim plus decoration on Anti-mould emulsion, installation of a Positive Input Ventilation (PVP) into the existing loft space and the use of Dryseal Water Repellence on existing stone/render from wall externally.

• Prepare walls ready to install 1.W.1 Wykamo Thermal Internal Eco System
• Wash all affected walls with a Wykamo Mould Removal Eradication Kit
• Mix and lay on walls a Iso-Therm Bond Adhesive. Once cut to size lay on the thin internal insulation and damp control (TWI) system ready to skim plaster over

Result is NO MORE BLACK MOULD!
