  • Sensitive electronic component areas.
  • Induction guided transport systems.
  • Chemical storage areas.
  • Solvent storage areas.
  • Bund areas.

  • Decontamination areas.

System components:

  • Top coat: 1 x Sikafloor 390AS.


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 substrate 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 and RH. If >4% by weight or >75% RH, Sikafloor® EpoCem® may be applied as a DPM system.

Other requirements:

Consult with manufacturer for application of earthing plates and connectors.
