Product information

Application

Surfaces

Cement/sand rendering, brickwork, aerated concrete
Screed, with or without underfloor heating, older than 14 days
Light-weight concrete, max. moisture content 8%
Flooring containing cement-based levelling compound.
Anhydrite floors, max. residual moisture 0.5%
Concrete in situ and precast units/slabs, older than 6 months
Paper-faced plaster boards, fibre-reinforced plaster boards
Existing tiles, terrazzo
Vinyl and paint on concrete

Plaster, wood, existing tiles, vinyl, and paint are not considered suitable surfaces for exterior use or in areas exposed to frequent or permanent water.

Surface preparation

The surface should be dimensionally stable, sound, and clean. Free from laitance, grease, and dust. There should be no blooms or crack formations. Residues from grease or soap can be removed with Alfix Deep Cleaner.

Ensure that paint is sufficiently adhering and non-flaking. Sand/Matt vinyl and paint with the appropriate sandpaper and apply a thin contact layer of Alfix CombiFix.

Straightening of lumps and unevenness of up to 5 mm can be carried out using Alfix CombiFix.
On absorbent, moisture sensitive interior surfaces, such as aerated concrete, gypsum plaster, plaster boards, and anhydrite floors, apply Alfix Primer (Sealing Primer) or Alfix PlaneMixPrimer.
For exterior use, apply a thin contact layer of Alfix CombiFix.

How to use

Add approx. 0.25 litres of clean, cold water per kg powder.

Apply Alfix CombiFix to the surface with a notched trowel, using the straight edge to spread out adhesive and subsequently the notched edge to produce a ribbed bed.

Fix tiles within 20-30 minutes by pressing them firmly into position in the wet adhesive with a slight twisting action. When fixing mosaics, a firm tap is required.
Ensure complete adhesive coverage!

For exterior use, e.g. stairs and facades, regardless of tile size, always apply adhesive to both tile and surface to ensure solid bedding leaving no voids (buttering/floating method).

NB!
Natural stone may call for extra attention.

Additional water should not be added to adhesive already starting to set.

Note that the temperature of mixing water will influence setting time.

Repositioning of tiles should be done within approx. 20 minutes after fixing, depending on substrate and tile absorbency.
Switch off any underfloor heating.

Cleaning

Clean adhesive residues from tools and tiles with water before the adhesive sets. Cement-based products harden when mixed with water, hence do not pour surplus adhesive into the drain system.
