Consumption

Yield

This depends on the substrate roughness and thickness of layer applied. As a guide, 1 bag yields approximately 11.5 litres of mortar
Application steps

MIXING

Place the water into a forced action mixer or in a clean drum. Slowly add complete bag of Sika® MonoTop -614F into the water and continuously mix for 3 minutes in mixer to achieve a uniform and lump free consistency. Alternatively use a slow speed drill (200-500 rpm) and spiral paddle mixer.

APPLICATION

Pour the mixed Sika® MonoTop -614F into the prepared repair area as soon as it has been mixed to maintain flow properties and no more than 30 mins to benefit from the shrinkage compensating properties. Ensure continuous mortar flow during the complete pouring operation to avoid trapping air.
For cold weather working consider using warm water to assist with achieving strength gain & other physical properties.
Reference shall be made to BS EN1504-10:2003 for specific requirements and any other guidelines that are specific to the structure.

CURING TREATMENT

It is essential to cure the repair mortar immediately after application for a minimum of 3 days to ensure full cement hydration and to minimise cracking. Use polythene sheeting taped down at the edges or other approved method.
Curing compounds shall not be used when they adversely affect subsequently applied products and systems.
Reference shall also be made to BS EN1504-10:2003 for specific requirements.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
