Ardex A55 – Self-Levelling Compound
Ardex A55 – Self-Levelling Compound. Ardex A55 is an advanced sub-floor smoothing and patching compound with rapid hardening and rapid drying properties, specifically designed for areas where the installation time of floor finishes must be kept to a minimum. When mixed with water, an exceptionally fluid, flexible self-levelling mortar is produced which can be applied from a feather edge up to the required thickness in a single operation. Dependent on substrate and application thickness, Ardex A55 can normally be walked on after approximately 60 minutes at 20OC. Ardex A55 dries and hardens rapidly by hydration, binding in the mix water so that, providing the Ardex A55 layer has hardened sufficiently and the adhesive trowel does not damage the mortar surface, the floor covering may be installed, even if the surface appears to be damp, typically after 60 minutes at 20OC.
- Can accept traffic and receive floor coverings after as little as 60 minutes
- Priming rarely required
- Exceptional flow and levelling characteristics
- Rapid hardening and drying performance
- Excellent coverage. 7.5m2 @ 2mm thick
- Can apply from feather edge to 10mm in a single application
Ardex A55 will level and smooth in a single application within the 15 minute working time. Applications include rapid repairs and smoothing tamped, uneven, damaged in-situ concrete, sub-floors, adjusting tolerances or camber problems between floors, slabs or pre-cast concrete, as well as smoothing old sub-floors and screeds in renovation projects prior to receiving resilient floor coverings such as vinyl and carpet. Ardex A55 is not designed to be a wearing surface.
