• Suitable for almost all subfloors
• High initial adhesion strength
• High final bond strength
• Easy to apply
• Permanent flexible
• Low chromate

• For the flexible fixing of wall and floor tiles on almost all subfloors (e.g. wood, concrete, old tiles etc.).
• Also very suitable for fixing wall tiles on uneven subfloors (e.g. lime-sand stone) and for fixing non-absorbent tiles on non-absorbent walls.
• Not suitable for outdoor applications and in case of water pressure (constant moisture-pressure). Use 705 Watertight Tile Adhesive, 711 Uniflex or 795 Uni-Quick.
• Because of the possibility of discoloration, 777 Flexicol grey is not suitable for fixing glass-mosaic and light-coloured natural stone, such as marble. For these applications we recommend 777 Flexicol white.

• The subfloor must have a good tensile and compression strength. The subfloor should also be smooth, dry and free from grease, dirt and dust, according to the requirements of DIN 18 352.
• Wooden floors, made of floorboards, should be sufficiently supported underneath (distance between the beam maximum 60 cm). To attain a fixed construction screw water-resistant plywood (minimum 12 mm thickness) on top of this layer. Thereafter apply 099 Dispersion Primerand primer. Maximum tile size 30x30 cm.
• For self-levelling anhydrite floors use our 725 Alphycol. 
• In advance always seek our technical data sheets. In doubt about the application ask for technical advice.

• Add 25 kg of 777 Flexicol to approx. 6 litres of cool and clean tap water and stir the mortar for one 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).
• Place the tiles within approx. 15 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.
• Apply the mixed adhesive within 90 minutes. Do not add extra water!
• Floor tiles are passable after 24 hours.
• 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). Check the adhesive contact regularly.
