Available in 25 kg PE lined paper bags.

Wooden floor constructions onto existing timber joist systems in areas up to 6 m². Joist spacing: 600 mm.
Concrete with or without underfloor heating, existing tiles, or terrazzo for bonded or floating coating on screeds.

The surface should be dimensionally stable, sound, clean and free from dust and laitance. For application on timber joisting apply rigid/hard insulation between joists and provide floating coat consisting of 2 layers of geotextile. Subsequently install reinforcement mesh, diameter 6 mm.
For surfaces requiring bonded coating, broom or brush the surface with a mixture of Alfix PlaneMixPrimer and Alfix PlaneMix 80 in the ratio 1:1.
Apply the mixture thoroughly by use of brush or broom and work it well into the surface.
Do not allow the slurry to dry before further treatment.
Ensure a room temperature of min. +10°C.

Add approx. 2.0 litres of clean cold water per 25 kg bag of powder. Use large mixing container, drum, paddle stirrer or electric drill and mix thoroughly for approx. 2 minutes until a semi-dry consistency is obtained.
Lay out PlaneMix 80 wet-on-wet onto the brushed surface and spread evenly. Upon compaction, level and render the surface by use of smoothing board/straight edge. If necessary, steel trowel the surface until it appears smooth and closed.
Application, rendering and trowelling should be done in one, ongoing work operation. Do not work over larger areas than can be completed within the 45 minutes working time stated.

Min. bed thickness – bonded screed on concrete: approx. 20 mm.
Min. bed thickness – floating screed: approx. 40 mm.
NB!
Additional water should not be added to screeding mortar alredy starting to set.
Note that the temperature of mixing water will influence working time/pot life.
Over dosage of water will reduce strength and may cause crack formation.
Switch off any underloor heating and allow 7 days before switching heating back on.
Tanking and tiling: 4 - 6 hours at +20°C
Dense coverings: 24 hours at +20°C
Levelling: Use Alfix PlaneMix S8 Rapid or alternatively Alfix PlaneMix S12 Rapid after 4 – 6 hours.

IRRITANT.

Tools and tiles should be cleaned with water before the mortar sets.
Cement-based products harden when mixed with water, hence do not pour surplus PlaneMix into the drain system.
