Application steps

MIXING

  • Water mix: Use the minimum amount of water necessary for ease of placement. The recommended water addition is 0.530 - 0.600 L per 5 kg bag.
  • Mixing sequence: Add 70% of the required water into the mixing vessel, then gradually add LANKO® 136 Rapid Patching Mortar while mixing. Slowly incorporate the remaining water until the desired consistency is achieved.
  • Site condition adjustments: Mixing ratios may vary based on site conditions. For optimal performance, ensure both the mixing water and substrate are between 5°C and 30°C. Small trial batches are recommended to determine the best working consistency.
  • Mixing method: Use an electric drill with a paddle mixer or mix by hand. Mix for approximately 3 minutes to achieve the best results.

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 LANKO® 136 Rapid Patching Mortar 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.

CLEANING OF EQUIPMENT

LANKO® 136 Rapid Patching Mortar should be removed from tools and equipment immediately after use with clean water. Any cured material may be removed by mechanical means.
