Prior to further installation, make sure that the relative humidity on location corresponds to the floor covering in question. Curing rate is influenced by temperature, humidity, ventilation, as well as sub-floor construction.

Tiling: 12 hours at +20°C for thickness up to 10 mm

Tanking and tiling: 24 hours at +20°C

Dense coverings: directional curing time: approx. 24 hours for layer in 10 mm thickness obtaining 85% RH.

How to use

Surfaces

Concrete subfloors, max humidity 95% RH. Cohesive strength should be min. 1 N/mm².
Anhydrite screeds, max. 0.5% residual moisture.

Ceramic tiles, terrazzo, and timber floors.

For further information and details, please contact our Technical Services Dept.

Surface preparation

The surface should be dimensionally stable, sound, clean and free from dust and laitance. Residues from grease or soap can be removed with Alfix Deep Cleaner.

To remove laitance or roughen smooth surfaces, use mechanical preparation, such as sanding or grinding, and vacuum subsequently.

All surfaces should be primed with Alfix PlaneMixPrimer. Ensure a room temperature of min. +10°C while working. Allow primer to dry before commencing further treatment. Application of smoothing compound should be made within 24 hours after priming.

Use self-adhesive foam tape to retain at doors, around floor drains, etc. If possible prevent compound from obtaining contact to walls. For thicknesses exceeding 5 mm, always apply self-adhesive foam tape for walls.

Should levelling imply several layers, priming before each new application is required.

How to use

Add 4.5-5.0 litres of clean cold water per 20 kg bag of powder. Pour water into a clean container and sprinkle in powder while stirring continuously.

If possible, use large mixing container or drum for more bags at a time and mix until a lump-free, easy-flowing mix is obtained. Mixing time is approx. 2 minutes using rotary drill paddle.

Pour or pump Alfix PlaneMix 20 onto the prepared substrate and spread with notched or straight trowel until the compound flows together into a smooth and even surface. For thicknesses exceeding 20 mm, incorporate kiln dried sand to extend coverage. 

If in doubt, please contact our Technical Services Dept.

Concrete, min. thickness: 1 mm

Exposure to chair castors, min. thickness: 2 mm

Timber floors, min. thickness: 10 mm

Top flooring, min. thickness: 5 mm (dry locations).

NB!
Additional water should not be added to levelling compound already 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 produce laitance. Protect from draughts, direct sunlight, and heat.
Close broken packaging carefully after use and use the rest within the shortest possible time.

Cleaning

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