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 render or screed, it should be fully cured for 7 days per 1 cm thickness of concrete before tiling.  

Tiles Preparation

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




  • Put 6.25 liters of clean water in a bucket (the water should be at room temperature, not warm or hot).
  • Gradually add weber.tai fix 
    • by the weight ratio of 1 part water per 4 parts of adhesive
    • or 1:3 by volume, in water and mix at the same time by using slow speed (500 rpm) electric mixer.  Or mix properly with a trowel 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.tai fix should be used within 4 hours and kept away from heat & sunlight.  


  • Apply some adhesive on the substrate, then use a notched trowel to equally spread the adhesive on the area of 1-2 m2.  The depth of the notched trowel is to control the constancy and quantity of adhesive.     
    • For floor: spread the adhesive on the substrate with the notched trowel.    
    • For wall: better spread the adhesive horizontally with the notched trowel (as shown in the picture) on the substrate.    
    • Using notched trowel will ensure a better transfer of adhesive onto both tiles back and substrates than using brick-laying trowel. 
  • Lay tiles on the adhesive and press firmly or knock gradually with rubber hammer in order to spread the notch of adhesive equally and ensure a good contact. 
    • Leave clearance joints, at least 2 mm, for grouting.
  • Carefully clean off any excess adhesive from the tiles and joints with a damp sponge while the adhesive is still wet.
  • Any adjustments can be done within 15 minutes before weber.tai fix sets.
  • Wait for 24 hours before grouting to let the adhesive dry completely.

Application Property

  • Pot life: 4 hours
  • Open time: 20 to 30 minutes
  • Adjustment time: 15 minutes
  • Time before grouting: at least 24 hours
  • Time before traffic: 24 to 48 hours
  • Recommended thickness: 2 to 10 mm  

Recommendation for Use

  •  Avoid applying the adhesive in lumps (as shown in the picture 1) at the tile back.  This will create voids underneath the tiles, which could lead to the tile fragility and water permeation.
  • Avoid using the adhesive on red-hot substrates or the substrates exposing to direct sunlight.  
  • To maintain straight joints, spacers should be used (as shown in the picture 2).  The joint width is controlled by the width of spacer.
  • To avoid water leakage into underneath tiles and to avoid tile movement when there is foot traffic, the joint width is recommended to be at least 1.5 mm for wall and at least 3 to 20 mm for floor.



  • 20 kg & 25 kg bag 
  • 3 to 7 kg per m2, depending on the size and weight of tiles 
  • Approximately 25 kg bag/5 m2  

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)
