Ardex FA20 Levelling Compound is an advanced fibre reinforced smoothing and levelling compound, featuring MICROTEC technology that is designed to rapidly smooth and level new and existing substrates prior to applying a floor finish.
Ardex FA20 can be applied to timber floors, flooring grade asphalt and existing substrates with adhesive residues. Can normally be walked on after approximately 2 hours at 20°C.
Ardex FA20 will level and smooth, in a single application, all uneven internal subfloors including concrete, cement/sand screeds, anhydrite screeds flooring grade asphalt, timber and non-moisture resistant chipboard; along with ceramic/porcelain tiled floors and well adhered non water soluble adhesive residues.
The standard mix is suitable for applications from 3mm to 10mm. For thicknesses between 10-20mm on to cement/sand screeds or concrete, add up to a third by volume of Ardex Coarse Aggregate.
Mixes with aggregate may require a subsequent smoothing layer of Ardex FA20. If an additional smoothing layer is required, this should be applied as soon as the floor becomes walkable. If the surface of the compound has dried, then it must be primed with Ardex P51 Primer diluted 1:3 with water.
Ardex FA20 dries and cures rapidly. Levelling layers up to 10mm are ready to receive floorcoverings after 24 hours at 20°C. For thicker layers the drying time is 2 days.
Ardex FA20 cannot be used externally, or in areas which are permanently wet.
Approximately 1.4kg of powder/m2/mm, e.g. one bag will cover approximately 5m2 at 3mm thickness. NOTE: The coverage figure above is based on a flat level surface, additional material should be allowed for where the surface is rough or uneven.
Bulk density: approximately 1.2kg/litre
Fresh weight of mortar: approximately 1.8kg/litre
Pot life (20°C): approximately 30 minutes
Walkability (20°C): after approximately 2 hours
