Product Typification

High quality floor tile adhesive with a filling ability.
Basis : Cement-based powder with additives and a high synthetic binder to be mixed with water.
Colour : White.

Product advantages:
  • Dust reduced
  • Layer thickness from 5 to 15 mm
  • For in- and outdoor use 
  • Flexible
  • Suitable for fixing tiles with a moisture-absorption capacity of 1% or less
  • Suitable for any type of natural stone
  • Fast drying
  • High final bond strength
  • For wall and floor
  • Very suitable for underfloor heating 

Performances

Classification : C2TE according to NEN EN 12004-2:2017. An improved cement-based tile adhesive with an increased flow resistance and an extended open time.
Consumption : 2.7-4 kg/m², depending on the smoothness of the subfloor and type of tile.
Curing : After minimum 24 hours the subfloor is passable, after 7 days the floor can be loaded. Lower temperatures will slow the drying time. During bonding of the adhesive the temperature during day and night must be > 5 ˚C.

Application

  • For fixing according to the thin or thick-bed method of large sized ceramic wall and floor tiles on almost all stony (irregular) subfloors.
  • Also suitable for all calibrated and non-calibrated natural stone, at what the differences of thickness between the boards must be filled with adhesive
  • Suitable for wall and floor applications and underfloor heating.

Working Process

Open time : Place the tiles within 15 to 20 minutes into the wet adhesive, depending on the subfloor and temperature.
Mixing ratio : Add 25 kg of 720 Unicol to 5-5.5 litres of water.
Waiting time : After mixing with water wait for a few minutes, stir once again and apply the mixture on the subfloor.
Application temperature : From 5° to 25 °C (temperature of the surrounding as well as the subfloor).
Processing time : Apply the mixture within 60 minutes.
Curing : After minimum 24 hours the subfloor is passable, after 7 days the floor can be loaded. Lower temperatures will slow the drying time. During bonding of the adhesive the temperature during day and night must be > 5 ˚C.
Storage : Store cool and dry in unopened packaging.
Shelf Life : 12 Months, in unopened packaging. After use close the open packaging well.

* The mentioned values have been established in our laboratory and must be considered as guidelines in view of possible variations in climatic circumstances, subfloor compositions and layer thickness.

Consumption:
2.7-4 kg/m², depending on the smoothness of the subfloor and type of tile.

Substrate:
  • The subfloor must have a good tensile and compression strength. The subfloor should also be smooth, dry and free from grease, dirt and dust.
  • When using the adhesive outdoors apply two layers of 730 Isoflex. Also remove all old ceramic finishing.
  • Prime moisture-sensitive or absorbent subfloors e.g. gypsum-based walls wit 099 Dispersion Primer. Apply 685 Eurocoat in the shower area to attain an impervious layer between the tile adhesive and subfloor.
  • Impervious surfaces, like existing tile work, degrease with 014 Euroclean. Thereafter let the surface dry sufficiently. Prime with 051 Europrimer Quartz or 044 Europrimer Multi.
  • For calcium sulphate (anhydrite) self-levelling anhydrite floors subfloors use 725 Alphycol.
  • In advance always seek our technical data sheets. In doubt about the application ask for technical advice. 


User manual:
  • Add 25 kg of 720 Unicol to 5-5.5 litres of cool and clean tap water and stir the mortar for 1 minute, by using an electric stirrer (approx. 600 rpm), to a smooth and homogeneous mixture.
  • After stirring wait for a few minutes, stir once again and apply the adhesive on the subfloor with the recommended adhesive spreader (see spreading capacity/notched spreader).
  • Press the tiles within 15 to 20 minutes with a shuffling movement into the adhesive. Check regularly to ensure that the back of the tile is in full contact with the adhesive. Remove excess adhesive immediately from the joints.
  • Always process natural stone full and thick according to the supplier's instructions. Do not use dot bonding due to possible drawing/discolouration of the natural stone.
  • Apply the mixed adhesive within 60 minutes. Do not add extra water!
  • For tile over tile applications, thick adhesive layers (10-15 mm) should be avoided. If necessary, first level these surfaces with 990 Europlan Direct.
  • Under normal circumstances, i.e. a temperature of 20 °C and a relative humidity of 65%, the joints may be filled after minimum 24 hours.

Spreading capacity/notched spreader for powder tile adhesives:

The smoothness of the subfloor and type of tile are determining for the adhesive spreader to be used. Selection of the notched spreader should be made in such way that a minimum adhesive contact of 80% is guaranteed (equally divided over the back of the tile). For outdoor purposes or large sized wall tiles this contact must be 100%. Also counts for heavy-duty indoor floors, e.g. store and warehouse floors. Check the adhesive contact regularly.

Notched spreader no. 13, 8x8 mm : Spreading capacity approx. 2.7 kg/m²
Notched spreader no. 14, 10x10 mm : Spreading capacity approx. 3.5 kg/m²
Notched spreader no. 15 : Spreading capacity approx. 4 kg/m²
