Product information

Product

Grey, fast-setting, polymer modified powder on the basis of aluminous cement.

Coverage

Approx. 1.7 kg per m² /mm thickness.

Flooring

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: 24 hours at +20°C

Tanking and tiling: Allow min. 48 hours at +20°C.

Application

Surfaces

Concrete subfloors, max humidity 95% RH. Cohesive strength should be min. 1 N/mm².
Ceramic tiles, terrazzo.
For further information and details, please contact our Technical Services Dept.

Surface preparation

Exterior
The surface should be dimensionally stable, sound, clean and free from dust and laitance.
Further, substrate should be water and frost resistant.
Existing concrete floors should be sanded/cleaned prior to levelling.
Concrete floors should be primed with Alfix PlaneMixPrimer diluted 1:6 with water.
Dense surfaces require pretreatment with Alfix Expoxy Grunder, 2-component epoxide primer system,
added sand once applied.
Priming of other surfaces, please consult our Technical Services Dept.
Outdoor temperature should be min. +10°C while working.
Allow primer to dry before commencing further treatment, usually drying time is 1 hour at +20°C.
Application of levelling 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.

Interior
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.
Prime absorbent surfaces with Alfix PlaneMixPrimer.
Prime non-absorbent surfaces with Alfix UniversalPrimer. Alternatively, wash/brush the surface with a
mixture of Alfix PlaneMixPrimer and levelling powder in the ratio 1:2.
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 3,2 – 3,6 litres of clean cold water per 20 kg bag of powder.

Amount of water per bag*)	3.6 litres	3.4 litres	3.2 litres
Layer thickness in mm	2 mm	15 mm	25 mm

*)Recommended amount of water

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 25 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 25 mm, incorporate kiln dried sand to extend coverage.

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, especially during the first 3 days upon application. If possible cover up with foil or plastic
sheet.
Colour and appearance of finished levelling layer will be influenced by substrate moisture content and
weather conditions.
Close broken packaging carefully after use and use the rest within the shortest possible time.
Always complete with a finished floor surface, for example ceramic tiles.

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.
