Application steps

MIXING

Pour 2.8 litres of clean water into a suitable mixing container and slowly add all the powder while mixing continuously with a mixing paddle attached to a low speed electric drill (max 500 rpm, with power approx. 1000 watt). Thoroughly mix until a smooth, lump free consistency is achieved. A minimum mixing time of 3 minutes is recommended. The water can be adjusted ± 5 % to suit the consistency desired.

 

APPLICATION

While bonding coat of SikaTop-121 or Sika MonoTop-910 N is still tacky, pack the mortar well into the cavity of repair. Use a placing rather than a rendering technique to fill all voids and ensure thorough compaction is achieved. Force the Sika MonoTop®-614 HS against the edge of the repair and progressively work towards the center. For repair in excess of 30 mm thick, apply in layers ensuring that each previous layer is sufficiently hardened and well keyed. If previous layers are over 48 hours old, scabble the surface and dampen. SikaTop-121 or Sika MonoTop-910 N may be used as a bonding slurry between layers Steel trowel the final layer if required to achieve a smooth, tight finish.

CURING TREATMENT

As with all cementitious based mortar, Sika MonoTop®-614 HS must be protected against direct sunlight and wind while hardening. Cover all exposed mortar with wet hessian, plastic sheeting or use Sika curing compound.
