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
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
