Pour approx. 90% of the maximum amount of water into a suitable clean mixing container. While stirring slowly add the complete bag of powder into the water. The remaining residual quantity of 10% may be required for consistency adjustment. Mix continuously for at least 3 minutes to achieve a uniform and lump free smooth consistency. Do not add more water than the maximum specified and no other additives / admixtures.

Sika MonoTop®-212 DE can be applied by hand or wet spray. As bonding bridge, Sika MonoTop®-910 N is to be brushed under pressure into the matt damp concrete surface. Sika MonoTop®-212 DE is applied immediately wet on wet to the previously applied bonding bridge and compact well.

For application without bonding bridge, a thin scratch coat must be applied first and then the intended layer thickness applied wet on wet.

Avoid cavities. The maximum layer thickness per working process must not be exceeded. If necessary, apply Sika MonoTop®-212 DE in several layers.

Wet spraying process
Sika MonoTop®-212 DE can be applied with all suitable wet spraying machines, e.g. PFT, Putzmeister, Mader, etc.
The specifications of the machine manufacturers regarding air, water and power supply must be observed. In order to achieve the best possible spraying results (high compaction, low rebound), the spraying angle should be 90 degrees.
Our recommendation of processing equipment is based on tests. Sika assumes no liability for success or failure in the use of the equipment.

After application the surface must be protect for at least 3 days against water evaporation and frost exposure until the sufficient strength has been achieved.

Suitable curing treatment:

• Water spray
• Foil covers with jute strips, thermal foils or moisturising cover strips

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