Sika MonoTop®-160 Migrating

Sika MonoTop®-160 Migrating

Cementitious crystallisation concrete waterproofing slurry

Sika MonoTop®-160 Migrating is a 1-part, cementitious waterproofing slurry modified with selected aggregates and active chemicals. The active components migrate within the concrete pore and capillary network and reacts with the available moisture and free lime to form a non-soluble crystalline structure within the network. The slurry can be applied by brush or spray and provides a waterproof layer to prevent the penetration of water to all types of concrete structures.

  • Migration of active components and crystalline formation to seal capillary network
  • 1-part system, only needs the addition of water
  • Slurry consistency for easy and fast application by brush or low pressure spray method
  • For positive and negative waterproofing
  • Excellent adhesion to concrete
  • Water vapour permeable
  • Application on concrete and repair mortars

Application steps

EQUIPMENT

Substrate preparation

  • Mechanical or very high pressure water blasting

Mixing

  • Low speed (< 500 rpm) hand drill mixer
  • Mixing Container

Application

  • Hand applied – slurry brush
  • Wet Spray – Low pressure spraying machine

Curing

  • Water spray equipment,moist geotextile membrane, polyethylene sheet

MIXING

Pour the minimum recommended clean water quantity in a suitable mixing container. While stirring slowly, add the full bag of powder continuously to the water. Once a consistent mix has been achieved, continue mixing for 3 minutes. The consistency must be checked after every mix.

APPLICATION

Thoroughly saturate the prepared substrate before application with clean water to achieve a saturated surface dry (SSD) surface. Before application remove excess water, e.g. with a clean sponge.

General

Sika MonoTop®-160 Migrating must be applied to the full surface area at the required layer thickness.

Hand Application

Apply mixed material onto the prepared pre-wet substrate by suitable slurry brush by working the slurry well into the substrate and without the formation of voids. A 2nd layer should be applied ‘wet on wet’ after allowing 1st layer to slightly stiffen to ensure full coverage of the surface and avoid ‘pin-holes’.

Sprayed Application - Wet Spray

The wet mixed Sika MonoTop®-160 Migrating shall be placed into the spraying equipment and applied onto the prepared pre-wet substrate. A 2nd layer should be applied ‘wet on wet’ after allowing 1st layer to slightly stiffen to ensure full coverage of the surface and avoid ‘pin-holes’.

CURING TREATMENT

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. water spray, moist geotextile membrane, polyethylene sheet, etc. Cure at least for 5 days after application.

CLEANING OF TOOLS

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