~ 5 l of injection grout

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

Sika® InjectoCem-190 is delivered in two precisely matched components. If required, a maximum of 0.2 l water can be added.


Place the liquid part B in a suitable mixing vessel. Mix with colloidal mixer at approx. 2 800 rpm and add the powder part A slowly and continuously. Mix the suspension thoroughly for at least 3 minutes.


Subsequently, pour the injection material directly into the pump or keep ready in a clean container.

CLEANING OF EQUIPMENT

Clean tools with water immediately after use. Hardened material can only be removed mechanically.
