Features & Benefits

• Designed for use in commercial and domestic locations, prior to the installation of resilient floorcoverings such as luxury vinyl tiles or sheet vinyl etc
• Ideal for the rapid skimming of plywood, patching, filling and feather finishing daywork joints, ridges, gouges, depressions, and uneven trowel marks, etc., in the subfloor, as well as smoothing joints between staggered plywood sheets
• Suitable for use on heated cement/sand screeds

Pack Contents

packed in paper sacks incorporating a polyethylene liner - net weight 11kg or 5kg.

Surface Preparation

The surface of the subfloor must be dry sound and free from dust, plaster, grease, paint, polish and any water-softenable or loosely adhered materials. Any remaining adhesive residues should be checked to ensure that they are not water-softenable and that they are hard, sound and have sufficient cohesive strength to receive a levelling compound.

In domestic applications only, Ardex Feather Finish may be installed over existing adhesive residues which are thin, sound and well bonded. The residues must not be affected by either the initial wetting from the applied Feather Finish or the adhesive used to install the new floor-covering. Ardex Feather Finish is not recommended over adhesive residues in commercial situations where high point loading may have adverse effects on the bond strength.

Mixing

The mix ratio is 2 parts of Ardex Feather Finish powder to 1 part water (by volume). Add the powder to the required amount of clean water in a clean mixing container whilst stirring thoroughly until a slump free mortar is produced.

Application

Ardex Feather Finish can be easily applied with a steel trowel, and used at a true feather edge, or up to 3mm in thickness. For thicknesses of 3mm, and not exceeding 12mm, it is recommended to build up in thin applications or alternatively consult the Ardex Ardurapid A 45 datasheet.

Note: When applying Ardex Feather Finish to wooden floors the maximum total depth is 3mm.

Drying and Hardening

As soon as the Ardex Feather Finish layer has hardened sufficiently, and the adhesive trowel does not damage the surface, the floorcovering may be installed. Depending on the absorbency of the subfloor and site conditions, a skim coat of Ardex Feather Finish should be sufficiently hard enough to receive the floorcovering after 15 minutes. Thicker applications will require additional drying time.

Note: Select a flooring adhesive that is compatible with the sub-floor beneath the Ardex Feather Finish, otherwise a 3mm smoothing layer wiII be necessary. Apply at temperatures above 5°C.

Protecting Unused Material

To preserve the rapid-drying properties the Ardex Feather Finish powder must be protected from exposure to the air whilst not in use. Protect unused bagged material by removing the air from the bag and sealing tightly. Open and reseal as necessary.

Coverage

An 11kg bag of Ardex Feather Finish, when used to smooth a plywood sub-floor, will give up to approximately 50m² of coverage when a skim coat is applied. Thicker applications will reduce coverage, e.g. 10m² at a 1mm thickness. A 5kg bag will cover 4.5m² at 1mm thick, or approximately 22.5m² as a scratch coat.
