Fixobond Flex II


FIXOBOND FLEX II is two components; highly polymer modified thin/ thick set premium grade ex adhesive. High polymer modification provides stability, high shear, tensile & bonding characteristics required for installation of artificial stone, natural stone & various tile over most surfaces. FIXOBOND FLEX IIsurpasses the requirements of IS 15477: 2004. FIXOBOND FLEX II can be used to adhere both wall and oor tiles and is suitable for interior and exterior use.

All surfaces must be clean, dry and free from any contaminates such as dust, oil, wax, grease, curing agents or other substances that may affect adhesion performance. Building debris such as off cuts, sawdust, nails, screws, plaster, wood etc., must be thoroughly cleaned with the help of wire brush - vacuum cleaner - damp sponge.
Note: If applying over existing tiles various preparation methods apply depending on surface and application. Do not apply over any deteriorating substrates. Ensure that new concrete slab is fully cured. Ensure that screeds have cured, normally after 7 days, depending on screed thickness and temperature. Ensure waterproof membranes have cured, minimum 24 – 48 hours after application.


Porous Substrates: Prime with ASCOBOND AR 470/OPC using by brush or roller. Allow primer to reach a touch dry film prior to applying FIXOBOND FLEX II. Do not over dilute primer. Mix 1 part of primer to 3 parts clean water. Extremely porous surfaces may require second coat.


Pour approximately 5 L of liquid additive in a clean vessel/container and gradually add 20 Kg of FIXOBOND FLEX II adhesive whilst mixing. (Slight water can be added in hot weather)Using a mechanical mixer at medium to high speed, mix powder and liquid additive together until smooth paste consistency is achieved. Allow to set a few minutes, re-mix before applying. Adhesive should not slump when combed out using the appropriate size notched trowel.


Tile installation must be undertaken in accordance with Indian Standard requirements. Ensure the back of the tiles to be adhered are free from dust or any materials which may inhibit adhesion.

  1. Spread FIXOBOND FLEX II adhesive over prepared surface/substrate using an appropriate notched trowel.
  2. When installing wall and floor tiles, lay one tile over adhesive then lift tile up again . Finished bed thickness should be a minimum of 4 mm for wall tiles and 3-6 mm for floor tiles.
  3. Ensure all tiles are fully supported by adhesive and that no voids are present.
  4. Inspect the underside of tile for complete bedding adhesion.
  5. Clean away any excess adhesive from the joints and face of the tiles whilst the adhesive is still wet.
  6. Ensure minimum grout joints of 1.5 – 3 mm spacing between tiles. Larger joints required for quarry / stone tiles. Refer to tile manufactures specifications.
  7. Allow to dry undisturbed for 24 hours prior to foot traffic and grouting.


Compatible with most solid substrates such as concrete, masonry, plaster board, fibrous cement sheeting, renders & screeds. All substrates should be pre-tested to ensure suitability.


Adhesive begins to set after an hour and is trafficable approximately 4 - 6 hours (longer if temperatures do not exceed 10°C) after installation depending on air and substrate temperatures. Grouting generally is best 24 hour after tiles have been installed. Optimum performance level is reached after 28 days of curing.


Clean skin with soap and water. Tools and equipment should be cleaned with solvent thinners.
