Weberset flex is a flexible, highly polymer modified, high performance, thin-set adhesive, for tiles, mosaics and stones, on a variety of substrates, which are prone to vibration. It is suitable for both vertical and horizontal application, in indoor as well as outdoor use. It is supplied as a dry mix mortar, to which water needs to be added before application. 

  • Flexible adhesive, which allows it to sustain low to medium vibration in the substrate.
  • Suitable for Internal as well as external use.
  • Highly polymer-modified provides high structural adhesion, which allows to be used on a variety of substrates, for fixing a variety of tiles and stones.
  • Can be used for new construction, as well as for renovation over existing floors/facades.
  • Long open time.
  • Prolonged and easy workability.
  • Low VOC – for healthy living. • No Hacking of substrate required to achieve the required bonding.
  • Self-curing properties, which allows for no-hassle application, with minimum labour.
  • The free-flowing product makes it easier to mix and apply.
  • No-sag formula: allows for hassle-free application on vertical walls, without any slippage.
  • Water-resistant, making it suitable for swimming pools, bathrooms, kitchen, saunas and spa.
  • Sustains heat ageing, making it ideal for high-temperature locations for outdoor use, and also for hot temperature applications, like Jacuzzi, sauna etc.
  • No shrinkage, prevents debonding and gives
  • Do not use on wet screed or plaster. The surface must be fully cured.
  • Do not use on gypsum plaster or boards, fibre cement boards, or other drywall partitions.
  • Can only be used on cementitious waterproofing. Do not use on epoxy or polyurethane waterproofing.
  • Do not use for Installing glass tiles or metal tiles. Use only Weber bond poxy, for fixing glass and metal tiles.
  • Do not use on metal, rubber, plastics, vinyl, linoleum surface, painted substrates. Contact weber representative for fixing these.
  • Do not use on surfaces subject to heavy vibrations. Use Weberfix drywall for areas subjected to heavy vibrations.
  • Do not use for fixing artificial stone or impregnated stone. Use Weberset ultra for the same.

Tutorials & Steps

  • Clean the substrate of oil stains and bond inhibiting compounds, dirt, dust and laitance, if any, using high pressure water jet or any other suitable method.
  • Ensure that the substrate is flat, stable, well adhered and has a normal absorption.
  • Concrete screeds, renders and block work should be cured sufficiently to avoid the shrinkage cracks.
  • Correct the local undulation/damage on the substrate at least 48 hours before the application of weberset flex.
  • Saturate the surface well and remove excess water before application of Weberset flex.
  • Gradually add 3 parts of Weberset flex to 1 part of clean water (by volume) and mix it to a lump free, smooth, workable paste using a suitable stirrer / low speed drill mix / or any other appropriate tool.
  • After mixing allow the mixture to stand for 2 minutes for it to mature.
  • Apply the adhesive onto the substrate covering up to 1 m2 at a time (or no more than can be tiled within 30 minutes). Unfavorable weather conditions (strong sun, dry wind, high temperatures, etc.) or a highly absorbent substrate can reduce the open time, even to just a few minutes. It is therefore necessary that careful checks be made to ensure that a skin does not form on the surface of the spread adhesive. If not, re-freshen the adhesive by re-spreading with a notched trowel.
  • It is not recommended to wet the adhesive with water once a skin has formed because, instead of dissolving the skin, the water will form an anti- adhesive film.
  • Apply Weberset firm over the surface using the straight edge of the notched trowel and then comb the applied adhesive using the notched side of the trowel to achieve the desired thickness.
  • Double buttering is recommended for heavier stones.
  • If the adhesive is buttered to the tile, then ensure proper coverage of the tile surface to evade voids.
  • Ensure Adequate gap is kept between subsequent stones/tiles to accommodate forthermal expansion and contraction.
  • Clean the stone/tile with water before installation.
  • Bed the tiles firmly into the adhesive with a slight sliding and/or twisting action/shear, to ensure a good and uniform contact.
  • It is good practice to lift an occasional tile after fixing, to verify that the required contact is being achieved.
  • In wet areas, external areas and all floors, the final adhesive bed should be free from voids.
  • If necessary, tiles should be adjusted, within 60 minutes of installation.
  • Carefully clean off any excess adhesive from the tiles and joints with a damp sponge or cloth before it sets. Leave for at least 24 hours before grouting.
  • More time may be required before grouting when tiling onto impervious or sealed surfaces or higher bed thickness.
  • For swimming pools, leave at least 3 days before grouting and then a further 17 days before filling.
