Application steps

MIXING

SikaRefit®-2000 should be mechanically mixed in a clean container using a low-speed electric mixer (max. 500 rpm). Place required quantity of clean water (5.0 L for 20 kg of SikaRefit®-2000) into a clean container and then add SikaRefit®-2000 slowly while mixing. A minimum mixing time of 3 minutes is recommended to thoroughly blends the components.

APPLICATION

SikaRefit®-2000 can be applied by spatula or trowel. Work the mixed mortar well into the substrate. Force material against the edge of the repair, working towards the center.

CURING TREATMENT

To achieve the full potential of any cement based material, curing is essential. In warm or windy weather, the use of standard curing methods are necessary (use of polyethylene sheets or damp hessian) to prevent premature drying out of mortar.

CLEANING OF TOOLS

Remove non-hardened SikaRefit®-2000 products from tools and equipment with water. Hardened material can only be removed mechanically.
