Product Description and Features

Product Description

weber.set ultra is a two component high performance polymer modified adhesive for fixing impregnated stone, tile and large format tile and stone where nominal substrate movement is expected.

Key Features

  • It is a ready to mix; two component product, where powder is added to a polymer liquid in a specified proportion to be applied.
  • 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 the foot traffic after 48 hours.
  • It is suitable for heavy duty applications with moderate structural movements.
  • It is recommended for external cladding.

Recommendation

  • It can be used for applications on cementitious substrate self leveling screeds and blocks.
  • It is suitable for fibre cement boards, gypsum boards, old tiles (porous and non porous) for both interior and exterior surfaces.
  • It can be effectively used on vinyl tiles and on a wooden floors using weber.tec prime.

Note - For application on any other substrate please contact Saint-Gobain Weber personnel for technical assistance.

Preparation and Application

Direction For Use

SURFACE  PREPARATION 

  • 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. For fresh plasters & screeds ensure complete curing as recommended.
  • 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 ultra.
  • Saturate the surface well and remove excess water before application of the tile adhesive.

Mixing Ratio

  • Gradually add weber.set ultra component A powder to weber.set ultra component B of polymer liquid 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 4 minutes for it to mature. 

Tile Fixing

  • Apply weber.set ultra 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 avade voids.
  • Firmly press the tile into the adhesive to ensure good adhesion.

Consumption

Single spreading – 4.5 kg/sqm
