Application Guide:
Mixing Ratio According to Consistency :
Flowable : 4.0 - 4.4 litres per bag
Pourable : 3.6 - 4.0 litres per bag
Stiff : 3.0 - 3.4 litres per bag (for special applications such as anchoring of starter bars)
Layer Thickness : 5mm min. / 50mm max. per pour
- Substrate Temperature : +10 °C min. / +40 °C max.
Application Steps:
Step 1 : Mixing
- Place 70-80% of clean water into a clean container and gradually add the whole bag of SikaGrout-215 into it while continuously mixing.
- Add the remaining water and continue mixing until desired consistency is obtained.
- Mix for 2 to 3 minutes with a slow speed drill and paddle.
Step 2 : Application
- After mix, stir lightly with a spatula for a few seconds to release any entrapped air.
- Immediately pour the grout into prepared formwork.
- When placing grout over a large area, it is important to maintain a continuous flow throughout.
Specific Areas of Application:
- Grouting under baseplate - pourable consistency
- Formwork grouting (ex: deep honeycombs, column reinforcements,etc) - flowable / pourable consistency
- Grouting anchor bolts - stiff consistency
- Grouting large volumes -
- For sections thicker than 50mm, fill SikaGrout®-215 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-215 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 : Curing Treatment
- If formwork repair is used, leave the formwork in place for at least 3 days.
- Upon removal of formwork, cure the exposed surfaces with Antisol-E.
Step 4 : Cleaning of Tools
- Clean all tools and application equipment with water immediately after use.
- Hardened and/or cured material can only be mechanically removed.
