Application steps

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.

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.

CURING TREATMENT

Immediately after finishing, exposed area should be thoroughly cured with wet hessian or curing compound, e.g. Sika® Antisol®

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
