Sika MonoTop®-618 VN should be mechanically mixed in a clean container using a low-speed electric mixer (max. 500 rpm). Place quantity of water
required (3.4 – 3.5 ltr for 25 kg of Sika MonoTop®-618 VN) into a clean container and then add Sika MonoTop®-618 VN slowly while mixing. A minimum mixing time of 3 minutes is recommended to thoroughly blends the components.

Priming

Concrete

Prior to the application of Sika MonoTop®-618 VN, Sika MonoTop®-610 should be applied as bonding bridge. Always work “wet on wet” on priming coats.

Two coats of Sika MonoTop^®-610 should be brush applied to the prepared steel (refer to Sika MonoTop^®-610 Data Sheet).

Brush apply a bonding coat onto the saturated surface dry substrate. Then, working wet-on-wet, work the mixed mortar well into the substrate using a rendering rather than a placing technique to fill all pores and voids. Compact well. Force material against the edge of the repair, working towards the centre. For repairs in excess of 20 mm deep, apply in layers ensuring previous layers are well keyed and hardened. Finish lower layers with a heavy brush stipple to form a key for subsequent layers. If previous layers are over 48 hours old, needle gun the surface and dampen. Steel trowel the final coat if required.

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 polythene sheets or damp hessian) to prevent premature drying out of mortar.

Remove non-hardened Sika Monotop products from tools and equipment with water. Hardened material can only be removed mechanically.
