DELTA membrane systems
Sealed System
The DELTA system is recommended for soil retaining situations such as basements and vaults. All membrane junctions, fixing points, service entries and protusions can be securely sealed. If active ground water is present or expected drainage can (and should) be incorporated into the system.
Ventilated System
Above ground, where no running water is expected, the ventilated system can be applied. With an air gap at the Top and Bottom, a 100 mm overlap is all that is required. This approach provides a sympathetic solution in Heritage properties, as the fabric of the building remains unchanged.
Floors
The system can be used to upgrade damp and defective floors, insulation can be added and it can be linked to the DPC of new walls or to the existing or chemical
DPC.

Antimould Breathable Replastering Paint
Description
Lectros Antimould Breathable Replastering Paint (ABRP) is a mould inhibiting microporous or “breathable” matt emulsion for use on damp or replastered walls.
The Lectros Antimould Microporous Replastering Paint has been formulated with specific features:
• High pigment volume concentration (PVC) to allow maximum water vapour permeability
• Use of special polymer to give good abrasion resistance of a “porous” film
• Low minimum film forming temperature (MFFT) of the polymer (5°C) which is ideal for newly replastered surfaces which will be relatively cold as they dry out.
• Excellent antimould performance for up to 2 years.
