Application steps

MIXING

Add water according to the desired consistency into a clean mixing vessel before slowly adding the Sika MonoTop®-615 HSF SA powder. Sika MonoTop®-615 HSF SA is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps, not longer than 5 minutes. Slow speed double paddle drill (maximum 500 rpm) can be also used for mixing. Normal tumble type concrete mixers are not suitable. Do not add extra water or other ingredients. Mix only full bags for the best result.

 

APPLICATION

Apply Sika MonoTop®-615 HSF SA while the bonding agent is still wet. The mortar can be applied by spatula or trowel.

For any thickness more than 40 mm, Sika MonoTop®-615 HSF SA must be applied in several layers.

As soon as the mortar has started to set it can be smoothed by wooden or synthetic float. For fine surface finish SikaRep® Fine SA, Sika MonoTop®-625 SA can be applied over the Sika MonoTop®-615 HSF SA.

CURING TREATMENT

Where ambient conditions may lead to rapid surface drying, the use of light water fogging for 48 hours or application of a suitable water based curing compound like Antisol®-WB is recommended. Do not commence fogging until final set has been reached.

CLEANING OF EQUIPMENT

Application and mixing tools should be cleaned with water while the material is still fresh. Hardened material can only be removed mechanically.
