PRODUCT DATA SHEET

Sika MonoTop®-615 HB HIGH BUILD POLYMER MODIFIED REPAIR MORTAR

DESCRIPTION

CHARACTERISTICS / ADVANTAGES

Sika MonoTop 615 HB is a cementitious, polymer modified, one component, repair mortar containing reactive microsilica. Sika MonoTop 615 HB is part of Monotop system for concrete repair and protection.

▪ Excellent high build and workability characteristics ▪ Enables rapid repair work to be undertaken. ▪ One component-just add water and mix. ▪ Layer thickness up to 80 mm are possible in vertical application. ▪ Micro silica and polymer modified. ▪ Good resistance to water and chloride ion penetration. ▪ Improve sulphate resistance

USES The lightweight nature of MonoTop 615 HB enables very thick layers to be applied in vertical and overhead applications. It is ideal for use in repairing damaged and spalled concrete caused by reinforcement corrosion. Sika MonoTop 615 HB can be used for most types of general concrete repair and refurbishment work.

APPLICATION INSTRUCTIONS

APPLICATION

SUBSTRATE QUALITY / PRE-TREATMENT

While bonding coat of Sikatop 121 is still tacky, pack the mortar well into the cavity of repair. Use a placing rather than a rendering technique to fill all voids and ensure thorough compaction is achieved.

The concrete substrate must be sound clean and free from oils, grease or surface contaminants. All loose materials and surface laitance must be removed by high pressure water jet blasting or by other mechanical means. Small areas and spot repairs should be mechanically prepared by needle gunning, bush hammering or similar. The prepared substrate should be dampened with clean water (SSD). Sika MonoTop 615 HB should be applied over a bonding coat slurry of Sikatop 121 or Sika Armatec 110 Epocem (refer to each data sheets). All feathered edges around the area to be repaired should be squared off with an angle grinder and chiselled down to a minimum depth of 10 mm MIXING Pour 2.6 litres of clean water into a suitable mixing container and slowly add all the powder while mixing continuously with a mixing paddle attached to a low speed electric drill (max 500 rpm, with power approx. 1000 watt). Thoroughly mix until a smooth, lump free consistency is achieved. A minimum mixing time of 3 minutes is recommended. The water can be adjusted ± 10 % to suit the consistency desired

Force the Sika MonoTop 615 HB against the edge of the repair and progressively work towards the center. For repair in excess of 80 mm thick, apply in layers ensuring that each previous layer is sufficiently hardened and well keyed. If previous layers are over 48 hours old, scabble the surface and dampen. Sika Top 121 may be used as a bonding slurry between layers Steel trowel the final layer if required to achieve a smooth, tight finish. CURING As with all cementitious based mortar, Sika MonoTop 615 HB must be protected against direct sunlight and wind while hardening. Cover all exposed mortar with wet hessian, plastic sheeting or use Sika curing compound
