Description

Sikafloor 29 PurCem is a three component, water based, high strength, coloured polyurethane mortar for detailing work and vertical rendering. It offers excellent resistance to abrasion, chemical attack and mechanical damage when used in conjunction with Sikafloor 20 PurCem screed mortar.

Suitable areas of application:

  • Food process plants.
  • Warehouses.
  • Chemical plants.
  • Pharmaceutical plants.
  • Power plants.
  • Storage areas.
  • Plant rooms.
  • Processing areas.
  • Laboratories.
  • Work shops.
  • Cold stores.

Preparation:

The cementitious substrate should be sound and of sufficient compressive strength (minimum 25 N/ mm²) and pull off strength (minimum 1.5 N/mm²). The surfaces must be dry and free of all contaminants, e.g. oils, grease, surface treatments and coatings, etc. The substrate must be prepared mechanically to achieve an open textured fine gripping surface, free of cement laitance. Weak concrete should be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed, preferably by brush and vacuum, from all surfaces before application of the coating. Repairs to cementitious substrates and filling of blowholes, levelling of irregularities, etc. should be carried out using an appropriate product from the SikaDur®, Sikafloor® or SikaGard® range of materials. Prior to application, confirm substrate moisture content. If >10% by weight, Sikafloor® EpoCem® may be applied as a DPM system.
