Stiff consistency - 3h : 00m
Application Steps:
Step 1 : Mixing
- Place 70-80% of clean water into a clean container and gradually add the whole bag of SikaGrout-214 into it while continuously mixing.
- Add the remaining water until desired consistency is obtained.
- Mix for 2-3 minutes with low speed drill.
Step 2 : Application
- After mixing, stir lightly with spatula for a few seconds to release any entrapped air.
- Immediately pour the grout into prepared formwork.
- When placing grout over a large area, maintain a continuous flow throughout.
- Grouting large areas:
For sections thicker than 100mm / other large areas, mix SikaGrout-214 with graded 10mm silt free aggregates to minimize temperature rise during curing stage.
Quantity of aggregates should not exceed 1 part aggregates to 1 part SikaGrout-214 by weight.
Make breather holes to ensure air entrapped during mixing can fully escape.
Use steel rods or chains to assist the flow of grout (if necessary).
Step 3 : Cleaning of Tools
Clean all tools and application equipment with water immediately after use.
Hardened and/or cured material can only be mechanically removed.
