Product Features

Key Benefits

  • Easy to use as it is both tile adhesive and tile grout
  • With Biocide to protect the grout from fungus or any dirt. Ideal for using in humid areas e.g. bathrooms and kitchens
  • Smooth and creamy texture


  • Density of powder : 0.9 – 1.1 g/cm3
  • Chemical curing time : 3 – 4 minutes
  • Pot life (in shade) : 2 hours
  • Waiting time after tiling before grouting : 2 hours
  • Time before traffic : 24 hours
    • Remark: These test results are from laboratory test. They could be slightly different from on-site results because of the differences in applications and conditions

Limit of use

  • Not suitable to use in swimming pool (instead of use weber.color HR or weber.color poxy)
  • Not suitable if grout is required to be chemical- and acid-resistant; industry, hospital, food-storage area, for instantce (instead weber.color poxy should be used)

Substrate preparation

  • The substrate should be flat, hard, level, clean, and dry with normal absorption.
  • Clean the surfaces until free from dust, grease, or any stains.
  • If the surface is very absorbent, it is necessary to damp it before tiling.
  • In case of new screed or render, it should be fully cured for 7 days per 1 cm thickness of concrete before tiling.


  • Put 1.1-1.2 liters of clean water in a bucket (the water should be at room temperature, not warm or hot).
  • Gradually add weber.color mosaic
    • by the weight ratio of 1 part water per 2.5 parts of adhesive 
    • (or 1:2.5 by volume) , in water and mix at the same time by using slow speed (500 rpm) electric mixer.  
    • When using traditional trowel, mix properly until homogeneous lump-free paste is obtained. 
  • After proper mix, leave the product for 3 - 4 minutes before using in order to have the complete chemical reaction.
  • The mixture of weber.color mosaic should be used within 30 minutes and kept away from heat & sunlight

Tile preparation

  • Tiles should not be immersed in water because it will decrease bonding strength of the adhesive.
  • Ensure that tiles are dry, clean, free from grease, dust, or any other contaminations.  

Application property

  • Pot life: 2 hours
  • Setting time: 20 to 30 minutes
  • Adjustability time: 10 minutes 
  • Time before grouting: 2 hours
  • Time before traffic: 24 hours
  • Recommended thickness: 2 to 10 mm

Recommendation for Use

For Tiling

  • Avoid applying weber.color mosaic in lumps (as shown in the picture) at the mosaic back.  This will create voids underneath the mosaic, which could lead to the tile fragility and water permeation

For Grouting

  • Avoid using weber.color mosaic on red-hot substrates or the substrates exposing to direct sunlight.



  • 3 kg bag (Approximately 1 m2 for both fixing and grouting/ 3kg bag)

Shelf Life & Storage

  • One year after manufacturing date when stored unopened in dry and ventilated place (store airtight in dry and ventilated conditions, if remained in opened bag)
