Pot life

~60 min (100 g mass, +30 °C)

(FIP 5.1)

Pot life begins when all parts have been mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into smaller quantities.

Application steps

SUBSTRATE QUALITY

CONCRETE

Concrete must be at least 28 days old.

Substrates must be sound, clean, dry or matt damp but free of standing water. Substrates must be free of contaminants such as ice, dirt, oil, grease, coatings, laitance, efflorescence, surface treatments and loose friable material.

  

STEEL

Surfaces must be sound, clean, dry and free of contaminants such as dirt, oil, grease, coatings and loose friable material.

SUBSTRATE PREPARATION

IMPORTANT

Reduced adhesion due to surface contamination

Surface contaminants such as dust and loose material, including the contaminants generated during substrate preparation, can reduce the Product's performance.

  1. Before applying the Product, clean thoroughly all substrate surfaces using vacuum or dust removal equipment.

  

CONCRETE

  1. Prepare the substrate mechanically using a suitable techniques as below:
    • Abrasive blast cleaning
    • High-pressure water blasting
    • Needle gunning
    • Scabbling
    • Bush hammering
    • Grinding
  2. Clean any pockets or holes for structural fixings to remove any debris.
  3. The substrate must have an open-textured, gripping surface profile.
 

STEEL

  1. Prepare the substrate mechanically using a suitable techniques as below:
    • Abrasive blast cleaning
    • High-pressure water-blasting
    • Grinding
  2.  Prepare the substrate mechanically using a suitable technique
  3. The substrate must have a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement.

SHUTTER FORMWORK

Preconditions

Where formwork is to be used, all formwork must be of adequate strength, treated with release agent and sealed to prevent leakage.

  1. Prepare the formwork to maintain a minimum 100 mm grout head to assist with placement.

Note: A grout box equipped with an inclined trough attached to the formwork will also improve the grout flow and reduce air voids.

MIXING

IMPORTANT

Poor workability and unfavourable handling time due to wrong mixing

When using multiple units during application, do not mix the following unit until the previous unit has been used.

     

  1. IMPORTANT Mix full units only. Prior to mixing all parts, mix Part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
  2. Add Part A to Part B (hardener) and mix Parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
  3. While mixing Parts A + B, gradually add Part C (aggregate).
  4. IMPORTANT Do not mix excessively. Mix until a uniform mix is achieved.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
