MIXING
Mechanically mix in an appropriately sized mortar mixer. Wet down all tools and mixer to be used.

APPLICATION
Reinforcement Corrosion Protection / Primer Coating
Where a reinforcement coating is required, apply to the whole exposed circumference of the steel the SikaTop 110 EpoCem or Sika Monotop 910N. The repair mortar must be applied into the coating ‘wet’ on ‘dry’.
Concrete Bonding Primer
Prime the prepared substrate with a scrub coat of SikaQuick®-2500 by firmly scraping the scrub coat over the substrate surface to form a thin layer and fill any pores or cavities in the surface. Ensure the whole surface to be repaired is covered by the scrub coat. The repair mortar has to be applied into primer ‘wet’ on ‘wet’.
Repair Mortar
The prepared mortar must be scrubbed into the substrate. Be sure to fill all pores and voids. force materials against the edge of the repair, working towards the centre. After filling the repair, screed of excess. Allow concrete to set to desired stiffness, then finish. If a smoother finish is desired, a magnesium float should be used. Mixing, placing and finishing should not exceed 15 minutes maximum.
To control setting times, cold water should be used in hot weather and hot water used in cold weather.
CURING TREATMENT
Moist cure should commence immediately after finishing. It is necessary to protect newly applied material from rain. To prevent from freezing, cover with insulating material.
