Product Description and Features

Product Description

weber.set plus grey is a polymer modified cementitious tile adhesive used for fixing ceramic tiles, vitrified tiles and stone of regular size on wall and floor with regular traffic. It is applicable for both interior and exterior conditions.

Key Features

  • It is a ready to mix; a single component product, just add water in the specified proportion and apply.
  • It has excellent adhesion properties, no slip is observed on vertical applications.
  • Shrinkage cracks are minimized/eliminated due to its self curing properties.
  • Larger quantity of material can be mixed at a time due to its longer pot life.
  • The tiled floor can be made available for foot  traffic after 24 hours.
  • It provides good water as well as heat resistance for external applications.


It is recommended for application on cementitious substrates, self leveling screeds and fibre cement boards.

Preparation and Application

Direction for use

  • Clean the substrate of oil stains and bond inhibiting compounds. Also remove 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 weber.set plus-grey.
  • Saturate the surface well and remove excess water before application of the tile adhesive

Mixing Ratio

  • Gradually add 2.5 parts of powder to 1 part of water (by volume) and mix it to a smooth, workable paste using a suitable stirrer or a low speed drill mix.
  • Do not attempt to extend the pot life by adding more water to the mix.
  • After mixing allow the mixture to stand for 2 minutes for it to mature.

Tile Fixing

  • Apply weber.set plus-grey 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. If the adhesive is buttered to the tile, then ensure proper coverage of the tile surface to evade voids.
  • Firmly press the tile into the adhesive to ensure good initial bonding.


For a 3mm bed thickness the coverage will be 4 - 4.5 kg/sqm
Note:The coverage will vary depending on surface undulations
