Sika MonoTop®-166 Migrating

CEMENTITIOUS WATERPROOFING BY CRYSTALLISATION

One part cementitious waterproofing slurry modified with selected aggregates and active chemicals. The slurry will migrate in the concrete pore to prevent the penetration of water to all types of concrete structures.

  • Migration of active components and crystalline formation to seal capillary network.
  • Resistance to positive and negative water pressure.
  • One component system requiring only the addition of clean water.

Application steps

MIXING

For Wet Application Method:

  • Mix with power drill one 25 kg bag with 7.25 to 7.75 litres of clean water until the product is evenly distributed.
  • Use mixing machine mix at low speed not over than 500 RPM.
  • Mixing time: at least 3 minutes or required consistency is obtained.
  • Leave the mixture to stand for 1 - 3 minutes.
  • Do not add water after mixing.

APPLICATION

Wet application method

  • Apply 1st coat by brush, float or pump at a rate of 1 kg /m2
  • Allow a sufficient drying time so that it is not drawn off while applying the 2nd coat. Apply 2nd coat, crosswise at a rate of 1 kg /m2.

Dry shake application method (Negative waterproofing)

  • Spread powerder of Sika MonoTop®-166 Migrating evenly onto the concrete after allowing fresh concrete to achieve initial set at the rate 3 - 3.5 kg /m2. Then, Trowel the surface for smooth finish.

Dry shake application method (Positive waterproofing)

  • Spread powerder of Sika MonoTop®-166 Migrating evenly onto the lean substrate before pouring the fresh concrete at the rate 2 kg /m2.

CURING TREATMENT

  • After Sika MonoTop®-166 Migrating coating has harden, cure the treated surface with a light mist of clean water at regular intervals tree times a day for initial two to three days.
  • In extremely hot weather curing period may have to be extended to several days.
  • On external areas are subjected to heavy rain or harsh sunlight. The finished application should be protected for at least 24 hours.

CLEANING OF TOOLS

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