Product facts


Grey, fast-setting, polymer modified powder on the basis of aluminous cement. Applicable by trowel or pump.




Approx. 1.7 kg per m² /mm thickness.


Available in 20 kg PE lined paper bags.



Expected Result


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.

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 for layers of up to 3 mm thickness and 7 days for layers of 30 mm thickness.
Dense coverings: directional curing time: approx. 3 days at +20°C for layers of 3 mm thickness obtaining 85% RH and 7-21 days for layers of 30 mm.

Surface preparation

Underlaget skal være bæredygtigt og rengjort for støv, fedt og overfladeslam.
Afrensning af fedt og sæberester foretages med Alfix Grundrens.
Overfladeslam afslibes, og underlaget støvsuges.
Glatte overflader matteres.
Alle underlag primes med Alfix PlaneMixPrimer.
Rumtemperaturen bør ikke være lavere end +10º C.
Primeren skal være tør inden videre behandling.
Spartling bør udføres senest 24 timer efter påføring af PlaneMixPrimer.
Anvend selvklæbende skumlister som begrænsning ved døre, gulvafløb mv.
Spartelmassen må ikke få vedhæftning til vægge. Ved lagtykkelser større end ca. 5 mm monteres selvklæbende kantbånd.
Hvis afretning udføres i flere lag, skal der primes før hvert nyt lag.

How to use

Add 3.6 - 4.4 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 30 onto the prepared substrate and spread with notched or straight trowel until the compound flows together into a smooth and even surface.
Concrete, min. thickness: 2 mm
Exposure to chair castors, min. thickness: 4 mm
Timber floors, min. thickness: 10 mm

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.


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.
