ARDEX RAPIDLAY MEMBRANE

ARDEX Rapidlay Membrane is a specially coated and patterned fibreglass reinforced sheet underlay designed to overcome the problems sometimes encountered in laying floor coverings, particularly sheet vinyl flooring, over new or old sub-floors in domestic and light commercial areas.

Usage:

• Screed or concrete substrates where construction moisture has not fully dried out (5% moisture content, 92% RH maximum).

• Anhydrite screeds with a maximum of 2% moisture content (carbide method).

• Areas where sub-floors have been exposed to water spillage.

• Old sub-floors which do not contain a fully functioning damp proof membrane.

• Over old, soundly fixed flooring when a temporary covering is to be applied (without adhesive).

• Suitable for use on heated concrete or cement/ sand screeds up to 27ºC maximum temperature.

Rapidlay Membrane should not be used in:

• Areas that are subjected to heavy wheeled traffic such as forklift or pallet trucks, chair castors etc.

• On timber bases that are not adequately ventilated.

• On sub-floors that are subject to hydrostatic pressure.

• On sub-floors which contain an effective damp proof membrane, but exceed a relative humidity of 97% and on sub-floors with no damp proof membrane and a relative humidity above 92%.

• On magnesite or composite floors.

• Biologically sensitive areas, or where floorings must be fully adhered, such as prisons.

Advantages:

• It provides a continuous base which is stable and resistant to damp.

• It cuts down laying time as there is no need to wait for the normal subfloor drying times.

• It is dimensionally stable.

• Quick installation can be achieved as it is a sheet system.

• Allows for a new temporary floor to be laid over an existing floor (without potential adhesive damage on uplifting).

• Low VOC and solvent free product.
