Alfix Sealing Membrane
Plaster, wood, existing tiles, vinyl, and paint are not considered suitable surfaces for exterior use or in areas exposed to frequent or permanent water
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 ProFix.
Straightening of lumps and unevenness of up to 10 mm can be carried out using Alfix ProFix.
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 ProFix.
How to use
Add approx. 0.27 – 0.35 litres of clean, cold water per kg powder corresponding to 5.4 – 7.0 litres of ready mixture per 20 kg bag depending on whether to use as non-slip wall adhesive or pourable floor adhesive.
Apply Alfix ProFix 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 tile sizes exceeding 60 X 60, apply adhesive to both tiles and surface to ensure solid bedding leaving no voids (buttering/floating method).
For exterior use, e.g. stairs and facades, regardless of tile size, always apply buttering/floating method.
Large-sized tiles and 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.
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.
