Application Guide:
- Mixing ratio : 3.6–4.5 L of water per 25 kg bag
- Yield : ~0.014m³ / bag
- Pot Life : ~30 minutes at +23 °C
- Initial Set Time : > 1 hour
- Final Set Time : < 4 hours
Application Steps:
Step 1 : Pre-Application
Substrate should be cleaned and roughened. All loose materials and free water must be removed. Damp the substrate with water before application.
Step 2 : Mixing
For optimum result, mechanical mixer should be used. The recommended amount of water (3.6–4.5 L) should be measured and poured into the mixer. Slowly add Sika MonoTop®-222 Patch Repair and mix continuously for 4 to 5 minutes.
Step 3 : Application
- Use a steel trowel to apply the mixed material onto the repair area.
- If the area that needs to be rectified is congested and cannot be reached with a trowel, use hands (wearing gloves) to push the pasty grout against the substrate and then trowel to a smooth finish.
- For application of joints between adjacent precast components, ensure that the material covers the joint spaces thoroughly.
- For horizontal joints, the subsequent precast component should be laid onto the grout within the pot life after mixing, depending on ambient temperature and conditions.
Step 4 : Curing Treatment
- Immediately after finishing, exposed area should be thoroughly cured with wet hessian or curing compound, e.g. Sika® Antisol®
Step 5 : Cleaning of Tools
- Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
