MASTERCURE WB-2 is a white pigmented component low viscosity wax-emulsion which incorporates a special alkali reactive emulsion breaking system. This system ensures that the emulsion breaks down to form a non-penetrating continuous film immediately upon contact with a cementitious surface. This impervious film prevents excessive water evaporation which in turn permits more efficient cement hydration, thus reducing shrinkage and increasing durability.
Once the membrane is formed, it will remain on the concrete surface until eventually broken down and eroded by natural weathering. When it is required to apply a further treatment to such concrete surface, it may be necessary to remove the membrane remaining after curing by wire brushing or other mechanical means.

Features / Advantages

  • No other curing necessary
    Eliminates use of water or sand completely.
  • Single application
    It forms moisture barrier for whole of the curing period..
  • Ensures hard wearing surface
    It minimises risk of drying shrinkage, cracks and dusty surfaces.
  • Reliable
    Hydrates efficiently.
  • Easy and safe spray application
    No-toxic and non-flammable.

Usage

  • Industrial Floor Slabs
  • Exterior Pavements
  • Walls and Columns
  • Parking Garages
  • Terrazzo Floors
  • Warehouses


Application

Exposed Concrete Slabs: It should be spray applied onto the slab on the newly placed concrete as soon as possible after the concrete is free from visible surface wafer, e.g. typically- 1/2 to 2 hrs. after placing.

Shuttered And Precast Concrete: It should be spray applied to all surfaces as soon as form work has been removed or the element demoulded.

In all cases the nozzle of the spray should be held approximately 450 mm from the concrete surface and should be passed back and forth to ensure complete and even coverage. The pump pressure should be maintained at a level to produce fine spray.

Rate of application depends on requirements but is typically within the range of 160 to 270 ml/m² (4.0 to 6.0 m²/litre)

Cleaning Of Tools And Equipments
Immediately after use the spray equipment should be cleaned out thoroughly with fresh water, if the spray nozzle becomes blocked with wax particles these can be easily removed using white spirit or similar solvents.

Storage And Shelf Life
It has a shelf-life of 12 months (One year) when stored at temperatures between 4°C and 35°C. Containers should be kept air tight to prevent surface evaporation.

Packing
5 Litre., 20Litre.. and 200 Litre. containers

Precautions
It is non-toxic. It Is advisable to wear goggles while spraying.
Inhalation of the spray. should be avoided, when It contacts with skin, should be washed thoroughly with plenty of water.
