Thoroughly wet the substrate to a saturated surface dry condition. Apply Sika Monotop 612 by the wet spray method. It can also be applied wet on wet by hand with a trowel or spatula onto the Sika Monotop 610 bonding bridge. For depths greater than 30mm thick, Sika Monotop 612 should be applied in layers.

In this case, as soon as the material has reached initial set, the surface should be given an open texture by rubbing with a wooden or plastic float prior to application of the next layer. Use Sika Monotop 610 bonding bridge for day joints and between layers if they are left to cure for more than 24 hours.

If a finer surface finish is required or a protective coating is to be applied, Sika Monotop 612 can be overcoated with Sika Monotop 620 surface leveling compound as required.
