Preparation & Application

Substrate Preparation

Substrate must be dry, sound, flat/true & free of contaminants. 

Adhesive Preparation

  • 1 pbw water to 3 pbw adhesive (6-7 ltrs Water or Latex Admixture to 20KG weberset superflex 21)
  • Mix weberset superflex 21 with water (or weber rage Latex Admixture) as per the recommended mix ratio. Mechanical mixing recommended.
  • Do not mix cement and or sand to Adhesive mixture. 

Application

step 1
step 2
step 3
step 4
  • Spread adhesive to the substrate at bed thickness of 3-6mm (may vary depending on tile size & thickness) with suitable notched trowel. 
  • Spread no more than 1m² at a time to avoid Skin-Over. Open time of spread adhesive is approx.15-20 minutes. 
  • Promptly fix tiles onto adhesive bed, followed by slight twisting action to ensure good contact. 
  • Lay tiles on the adhesive and press firmly or knock gradually with rubber hammer in order to spread the notch of adhesive equally. 
  • Allow to set for 24 hours; before grouting commences. Allocate joints of approx.3mm wide between tiles. 
  • Remove surplus adhesive from tile surface & joints before it hardens. 

Recommendation for Tiling

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

Recommendation for Grouting

•To maintain straight joints, spacers should be used (as shown in the picture).  The joint width is controlled by the width of spacer.
•At least 24 hours after completion of tiling or until adhesive had set. Setting may be delayed on dense or impervious surfaces.
•Allocate joints of approx. minimum 3mm wide between tiles. Joints width may vary depends on tile size.

Self Life & Storage

•6 months after manufacturing date when stored unopened in dry condition of normal ambient temperature.
