Sika MonoTop®-122 F BD

DUAL SHRINKAGE COMPENSATED, TROWELABLE FIBRE REINFORCED THIXOTROPIC REPAIR MORTAR

Sika MonoTop®-122 F BD trowelable mortar is a dual shrinkage compensated, thixotropic high strength formulation for structural concrete repairs. Sika MonoTop®-122 F BD is suitable for placing in thicknesses of 5mm to 50 mm vertically and 5mm to 15 mm overhead.

  • Easy to use (only to be mixed with water)
  • Excellent workability
  • Adjustable consistency
  • Structural and Cosmetic repairs 
  • Applicable in layers up to 50 mm thickness (vertical surface)
  • Good adhesion strength
  • High abrasion, wear and impact resistance
  • Ideal where the repairs are more than 5 mm
  • Non corrosive, non toxic
  • Increase resistance to salt water, chlorides and carbonation
  • Sprayable - able to repair complex profiles easily with minimal rebound

Application steps

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 BD 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 at least 3 minutes.

APPLICATION

Apply Sika MonoTop®-122 F BD 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.

CURING TREATMENT

Protect the fresh mortar immediately from premature drying using an appropriate curing method e.g. curing compound, moist geotextile membrane, polythene sheet, etc.

CLEANING OF EQUIPMENT

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