MIXING
Mix powder mechanically in the correct ratio with water with low speed (max. 500 rpm) electric drill to avoid entraining too much air. In case of 2 or more bags at once use forced action mixer.
Put around 80 to 90% of required water in the mixing drum, followed by Sika MonoTop ® 122 F and then add the balance water.
Don’t use concrete tilting mixer.
Do not mix more material which cannot be used within Pot Life. DO NOT ADD EXTRA WATER.
Mix for atleast 3 minutes.
APPLICATION
Apply Sika MonoTop®-122 F manually using traditional techniques
When a bonding primer is used, ensure it is still ‘tacky’ when the repair material is pressed on (‘wet on wet’ technique). When applied manually, press the repair mortar firmly with a trowel, pushing it well on to the substrate.
Smoothening with trowel or finishing by Float or sponge can be done as soon as mortar has started to stiffen.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
