At Water : Powder ratio of 0.13
MIXING
Water : Powder = 0.13 by weight (3.9 l water per bag)
Mix for atleast 3 minutes minimum
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 SikaTop®-122 HS 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.
APPLICATION
SikaTop®-122 HS can be applied either manually using traditional techniques or mechanically using wet spray equipment.
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.
Finishing with both hand and machine application should be done as soon as mortar has started to stiffen.
CURING TREATMENT
Protect the fresh mortar from excess evaporation from the surface and early dehydration using the relevant curing method.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
