Application steps

MIXING

Sika MonoTop® -610 can be mixed with a slow speed (< 500 rpm) electric drill mixer. Pour the water in the correct proportion into a suitable mixing container. While stirring slowly, add the powder to the water. Mix thoroughly for at least 3 minutes to the required consistency.

APPLICATION

Reinforcement Corrosion Protection/Primer:
Apply first layer approx. 1 mm thick, using medium hard brush or spray gun to the cleaned reinforcement. Apply 2nd layer when the first coat is fingernail hard (~2 - 3 hours at +20°C).If the second coat of Sika MonoTop® -610 is allowed to dry prior to repair mortar application, then a fresh coat must be applied.

Bonding Primer/Bridge:
Apply using medium hard brush or spray gun to prepared substrate. To achieve good bond, Sika MonoTop® -610 must be applied well into the substrate, filling all pores.
Reference shall 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.
