Product information

Product

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

Coverage

Approx. 1.7 kg per m²/mm thickness.
For straightening/screeding with 15-30 litres of Leca pearls Ø 2-4 mm per 20 kg powder.

Packaging

Available in 20 kg PE lined paper bags.

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.

Tanking: For wet room use, always apply waterproof sealing membrane onto levelling compound.

Tiling: 24 hours at +20°C
Dense coverings: directional curing time is 1 – 7 days.

Prior to coating, the relative humidity must be known and matched to the current coating type. Drying depends,
among other things, of temperature, humidity and ventilation as well as the suction of the underlying
structure.

Tiling: After 24 hours at + 20ºC / 50% RF.
Alfix Wet room system: After 24 hours at + 20ºC / 50% RF for layer thicknesses up to 35 mm and after 48
hours at + 20ºC / 50% RF for layer thicknesses of 35-50 mm.

Dense coatings such as vinyl or the like can be done after 1-3 days according to the following guidelines
measured at + 20ºC / 50% RF:
After 24 hours at layer thicknesses between 1-32 mm.
After 48 hours at layer thicknesses up to 40 mm After 72 hours at layer thicknesses up to 50 mm
Recommended moisture content: Max 85% RF.

Application

Surfaces

Concrete subfloors, max humidity 95% RH. Cohesive strength should be min. 1 N/mm².
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.
For absorbent surfaces, such as concrete, dilute Alfix PlaneMixPrimer with clean water in the ratio 1:3.
For smooth or dense substrates, wash/brush the surface using 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 3.0-3.6 litres of clean cold water per 20 kg bag of powder.
Add 3.0-3.6 litres of clean cold water per 20 kg bag of powder.

Amount of water per bag*)	3.6 litres	3.3 litres	3.0 litres
Layer thickness in mm	2 mm	25 mm	50 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 50 less dust 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
Timber floors, min. thickness: 10 mm
Top flooring, min. thickness: 5 mm (dry locations).
Top flooring, epoxy paint min. thickness: 5 mm.

NB!
In wet rooms, a waterproofing/tanking layer must always be applied on top of the levelling compound.
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.
Slope building/gradient levelling: reduce amount of mixing water to 3 litres per 20 kg powder.
Straightening/screeding: With addition of Leca pearls Ø 2–4 mm a screeding mortar with good workability suitable for thicknesses 3 – 15 cm is obtained.

Cleaning

Do not throw leftover levelling compound on the ground at the construction site, the tile adhesive contains ingredients that break down very slowly in nature. When levelling compound has set, it can be disposed of like normal construction waste.
