Surface Preparation


All substrates must be free from oil, grease and loose particles.

Concrete, natural stone, cement mortar and render:

  • Age of concrete must be 3 – 6weeks
  • Clean of oils, grease, dust and cement laitance
  • Prepare with blast cleaning or grinding

Construction steel 37, V2 A steel:

  • Clean of oils, grease, rust or mill scale.
  • Avoid dew point conditions.
  • Prepare surface with blast cleaning or grinding, and prepare immediately prior to use with Sika Primer MB

Polyester, epoxy, ceramics:

  • Clean of oils and grease
  • Prepare surface with grinding – use a coarse abrasive for polyester epoxy



Application Instructions


Sag Flow

  • None, suitable for overhead application

 

Application

  • Temperature range for application (ambient and substrate) must be 10°C to 35°C
  • Prepare the cartridge by unscrewing the cap and then pulling out the plug
  • Screw on the static mixer nozzle and insert into cartridge gun
  • Pump gently until both components begin to come out evenly – do not use this initial material and wipe the nozzle clean before use
  • Apply the adhesive and ensure that the fixing does not move during the curing time (see table below)
  • Layer thickness must be 0.5mm to 10mm
  • The static mixer nozzle can remain on the cartridge and re-used during short interruptions to work (up to 60 minutes – will vary with ambient conditions)
  • If the resin hardens within the nozzle, then it will need to be replaced

Curing Time

Temperature Open Time Curing Time*
10°C 210 minutes 3 days
20°C 90 minutes 2 days
35°C 45 minutes 1 days



*To achieve 80% performance

Cleaning Of Tools

  • Wash tools immediately with Sika Thinner C
  • Wash hands and skin thoroughly with warm, soapy water



Limitations


  • Can be used with damp (not wet) substrates
  • Ensure there is no standing water during application and curing
  • Mortar and concrete must be older than 28 days
  • Adequate substrate strength must be confirmed prior to application
  • Ambient and substrate temperature must be between 10 °C and 35 °C
  • Apply at a maximum air humidity of 85% (at 25 °C)
  • Avoid condensation during dew point conditions
  • Substrate temperature during application must be at least 3°C above dew point
  • Sika Concrete Crack Repair is formulated to have low creep under permanent loading. However, due to the creep behaviour of all polymeric materials under load, the long term structural design load must account for creep
  • Generally, the long term structural design load must be lower than 20-25% of the failure load
  • Please consult a structural engineer for load calculations for your specific application
