APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
The substrate must be sound, clean, free of oil and grease, old coatings and other contaminations.
For good adhesion, pre-treat the substrate with high pressure water or mechanically.
Use air pressure to remove dust from cracks.
MIXING
Place the liquid part B in a suitable mixing vessel. Mix with colloidal mixer at a minimum 2 800 rpm and add the powder part A slowly and continuously. Mix the suspension thoroughly for at least 5 minutes.
Subsequently, pour the injection material directly into the pump or keep ready in a clean container.
APPLICATION METHOD / TOOLS
The injection material can be injected with commercially available equipment designed for cement injections (injection pressure 3 - 8 bar).
Start injecting at low pressure and build as necessary.
For vertical injection sections, inject from bottom to top.
If dry concrete has to be injected, it is recommended to pre-wet the concrete with water under light pressure.
In order to enable post-injections, the freshly injected section of the SikaFuko® systems (or the injection packers) must be thoroughly rinsed.
CLEANING OF TOOLS
Clean tools with water immediately after use.
Hardened material can only be removed mechanically.
