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 LetFix less dust, mixed with Alfix
FlexBinder, if appropriate.
Straightening of lumps and unevenness of up to 5 mm can be carried out using Alfix LetFix less dust.
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 PlaneMixPrimer mixed with water at a ratio of 1:6.
How to use
Add approx. 0.4 – 0.5 litres of clean, cold water per kg powder depending on whether to use as non-slip
wall adhesive or pourable floor adhesive.
For optimal standing strength, add a maximum of 0.43 liters of water per kg powder.
Mix to a lump-free mass, maximum mixing time 1 minute.
Apply Alfix LetFix less dust 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.
Press/wiggle the tiles in place in the moist adhesive immediately – and within no more than 20–30
minutes. When installing mosaics, smooth the ridged layer of adhesive from the notched trowel to create
a level bed of adhesive. Press/tap the mosaic tiles in place in the moist adhesive using a grout float, for
example. Ensure complete adhesive coverage!
For tile sizes exceeding 600 x 600 mm, apply adhesive to both tiles and surface to ensure solid bedding
leaving no voids (buttering/floating method).
For exterior use, e.g. terraces, stairs and facades, regardless of tile size, always apply buttering/floating
method.
Tile formats larger than 600 x 600 mm will require extra drying time and will take longer to be ready for foot
traffic/grouting. Alternatively, you can use: Alfix ProFix, Alfix CombiQuickFix and Alfix QuickFix premium.
NB!
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. 20-30 minutes after fixing, depending on substrate and
tile absorbency.
Switch off any underfloor heating.
Cleaning
Do not throw leftover tile adhesive on the ground at the construction site, the tile adhesive contains ingredients that break down very slowly in nature. When the tile adhesive has set, it can be disposed of like normal construction waste.
