Application Steps
- Substrate Quality: Concrete and mortar must be older than 28 days. Surface must be clean, dry or mat damp (no standing water), and free from oil, grease, coatings, and loose particles. Steel must be de-rusted to Sa 2.5 standard.
- Substrate Preparation: Concrete/mortar/stone/bricks: remove laitance and contaminants to achieve an open-textured surface. Steel: blast clean and vacuum; avoid dew point conditions.
- Mixing: Mix components A+B for at least 3 minutes with a mixing spindle at max. 300 rpm until smooth and uniform grey. Pour into a clean container and stir for 1 more minute at low speed to minimise air entrapment. Mix only the quantity usable within pot life.
- Application: Apply directly to the prepared substrate. For vertical surfaces, product is non-sag up to 15 mm. Do not mix the next unit until the previous one is fully used. To extend workability at high temperatures, divide mixed adhesive into smaller portions or pre-chill components (not below +5°C).
- Cleaning: Clean all tools immediately after use with Sika® Colma Cleaner. Hardened material can only be removed mechanically.
