Substrate preparation

  • The joints should be clean and dry before grouting.
  • Clean and remove any particles or contaminations remaining in the joints in order to ensure a good grout adhesion and the color uniformity.  


  • Put clean water in a bucket (the water should be at room temperature, not warm or hot).
  • Gradually add weber.color no stain in the water and mix at the same time until homogeneous lump-free paste is obtained.  The mixing proportion is;     
    • 1:3           by weight (water : grout)   
    • 1:2.5        by volume (water : grout) 
  • 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 no stain should be used within 30 minutes and kept away from heat & sunlight.  


  • For wall: Use weber rubber trowel or an appropriate tool to fill tile joints diagonally.    
  • For floor: Apply the mixed grout onto the area of 1 m2, and then use the rubber trowel to diagonally fill the joints.
  • Wipe off the excess grouts with damp sponge before the grout sets.
  • Clean tile surfaces with clean cloth after 2 hours.
  • Wait for 24 hours before traffic to ensure the good bonding of grout.  



Application property

  • Pot life: 30 mintes 
  • Setting time: 24 hours
  • Time before traffic: at least 24 hours 
  • Recommended joint-width: 1 to 6 mm
  • Application temperature: +5°C to +35°C  

Recommendation for Use

  • Avoid grouting when raining or cover the grouting areas in order to prevent stain that can be occurred when tile grout is not set. 
  • In case of clay tiles or porous tiles, weber.klin tec should be used before grouting to protect the tile surfaces from grout-color stains. 
  • Using spacer while tiling to neatly keep the joint lines. Size of spacer defines the joint width. 
  • To protect water leakage into underneath tiles and to avoid tile movement when there is foot traffic, the joint width should be at least 1.5 mm for wall applications and should be at least 3-6 mm for floor applications. 
  • In case shortage use of weber.color no stain in a box set, you can use weber.color HR or weber.color poxy instead. 



  • 1 kg bag (One bag could be used with the area of 19 m2 approximately.)      


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)
