Uses
▪ Patching of joints between precast and structural components
▪ Repairs concrete structures and pre-cast components, e.g. damaged corners
▪ Patch repairs to vertical, soffit and flooring concrete surfaces
▪ Filling concrete cavities in electrical, piping and airconditioning works
▪ Securing foundation and anchor bolts, pipe clips, sanitary wares, etc.
▪ Repair concrete conduits, drains, etc.
▪ Surface irregularities repairs including exposed aggregates, joints between new and old concrete, protruding steel, tie-rod holes in formwork concrete, etc.

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®.

Important Considerations
▪ For surfaces subjected to high abrasion, Sika Monotop^®-412 MY should be used as repair mortar.
▪ Sika MonoTop^®-222 Patch Repair should not be used on smooth concrete surfaces. Thorough roughening of the surface will be required.
▪ Sika MonoTop^®-222 Patch Repair should not be used for pouring or pumping into formwork. Kindly refer to SikaGrout^® range.
▪ Cement or admixtures should not be added to Sika MonoTop^®-222 Patch Repair.
▪ Once the mix has begun to set, do not add water.
▪ Refer to the Method Statement for Concrete Repair using Sika MonoTop^® system for more information regarding substrate preparation.
▪ Avoid application under direct sun and/or strong wind.
▪ Apply only to sound, roughened and well-prepared substrate. Do not add additional water during the surface finishing phase as this will cause discoloration and cracking.
