APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Substrate should be cleaned and roughened. All loose
materials and free water must be removed. Damp the
substrate with water before application.
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.
