SUBSTRATE PREPARATION
Concrete / brickwork
Substrate must be clean and sound. Cracks may be dry or damp but free of standing water. Remove from cracks by suitable preparation techniques dust, loosely adhering particles and other contaminants that will affect injection and adhesion.
MIXING
Prebatched kit packaging:
Add all of part B to part A. Mix with an electric mixer at slow speed (max. 250 rpm) for at least 3 minutes. Avoid entraining air.
Bulk packaging:
Add both parts in the correct proportion into a suitable clean, dry container and mix in the same way as for the prebatched kit units. Mix only the quantity that can be used within its pot life.
CLEANING OF TOOLS
Clean all tools and application equipment using the Sika® Injection Cleaning System in accordance with the Product Data Sheet. Hardened material can only be mechanically removed.
