• Substrate preparation -Mechanical or very high pressure water blasting
• Mixing - Low speed (< 500 rpm) hand drill mixer and Mixing Container
• Application - Hand applied: slurry brush, Wet Spray: Low pressure spraying machine
• Curing - Water spray equipment,moist geotextile membrane, polyethylene sheet

Pour the minimum recommended clean water quantity in a suitable mixing container. While stirring slowly, add the full bag of powder continuously to the water. Once a consistent mix has been achieved, continue mixing for 3 minutes. The consistency must be checked after every mix. 

Thoroughly saturate the prepared substrate before application with clean water to achieve a saturated surface dry (SSD) surface. Before application remove excess water, e.g. with a clean sponge.

General

Sika MonoTop®-163 Migrating KE must be applied to the full surface area at the required layer thickness.

Hand Application

Apply mixed material onto the prepared pre-wet substrate by suitable slurry brush by working the slurry well into the substrate and without the formation of voids. A 2nd layer should be applied ‘wet on wet’ after allowing 1st layer to slightly stiffen to ensure full coverage of the surface and avoid ‘pin-holes’.

Sprayed Application - Wet Spray

The wet mixed Sika MonoTop®-163 Migrating KE shall be placed into the spraying equipment and applied onto the prepared pre-wet substrate. A 2nd layer should be applied ‘wet on wet’ after allowing 1st layer to slightly stiffen to ensure full coverage of the surface and avoid ‘pin-holes’.

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. water spray, moist geotextile membrane, polyethylene sheet, etc. Cure at least for 5 days after application.

Clean all tools and application equipment with water immediately after use.
