• Highly deformable; S2 (> 5 mm) complying with NEN-EN 12004;
• Very high-capacity stress absorption
• Universally applicable
  
• Lighter lifting weight due to lighter fillers
• Very economical in use
• Extended open time
• Can be applied to fresh screed
• Suitable for indoor and outdoor applications
  
• Suitable for underfloor heating

• Thin-bed adhesive for very flexible bonding of ceramic (large format) floor tiles and slabs, composite tiles, ceramic mosaic and flat, non-discolouring sensitive natural stone on fresh screed (cement-bonded screed floors), wood, existing tiling, granite and underfloor heating.
• Suitable for bonding (large format) floor tiles on interior walls in dry and wet areas using the stacking method, possibly in combination with a tile leveling system.
• Suitable for swimming pools and floors with heavy loads.
• Suitable for bonding tiles on sanded or blasted concrete; at least 28 days old, swimming pools and heavily loaded floors.
• Very suitable for indoor and outdoor applications where this adhesive often makes a decoupling mat unnecessary.
  

• The substrate must be sufficiently pressure-resistant and tear-resistant. The substrate should also be flat, dry and free of grease, dirt and dust.
• The bonded screed/subfloor can be given the selected ceramic finish after 1-3 days and for a floating screed/subfloor after 7 days. This applies at an ambient temperature of approximately 20°C and a relative humidity of 50 – 65%. It is also important that, before adhesive bonding, any underfloor heating is stoked up and cooled down according to the current stoking protocol.
• We recommend 740 Isoflex 2K for watertight finishing of stony surfaces on balconies and terraces on which tilework is applied.
• In many cases, this adhesive can make a decoupling system unnecessary in outdoor applications. This depends on various factors such as tile size, colour (reflection value), location, etc. Please consult our technical advisors.
• Wooden floors consisting of floor parts must be sufficiently supported (maximum beam distance 60 cm). Screw water-resistant plywood (at least 12 mm thick) onto it to create a rigid structure. Then apply 099 Dispersion primer. Maximum tile size 30x30 cm.
• Use 725 Alphycol on calcium sulphate bonded screeds (anhydrite).
• Always consult our technical product information sheets. Should you have any doubts about the use of the product, please contact our Technical Help Desk first.
  

• Add 20 kg of 733 Superior S2 to approx. 5.5 (thin bed) – 6.5 (fluid bed) litres of cool and clean tap water; mix the mortar mechanically with the Eurocol 855 Mixing Iron (at approx. 600 rpm) for 1 minute until a lump-free mass is obtained.
• Leave the mortar to stand for several minutes, stir well again and apply to the substrate using the correct adhesive comb (see images of use/toothing). Adhesive layer thickness 6 mm maximum.
• Press the tiles into the adhesive bed with a sliding movement within 15 - 20 minutes. Check often that the backs of the tiles always come into full contact with the adhesive. Remove excess adhesive from the joints.
• The prepared adhesive must be processed within 60 minutes. Do not add extra water to mortar that has already been bonded.
• In normal conditions, i.e. a temperature of 20°C with relative humidity of 65%, the tilework can be grouted after at least 24 hours.
  

Spreading capacity/notched spreader for powder tile adhesives:

The flatness of the substrate and the type of tile are all-important when choosing the toothing of the adhesive trowel. The choice of toothing must be such that a minimum adhesive contact area of 80 - 100% is achieved (evenly distributed over the back of the tile). Check the adhesive contact surface regularly.
