Materials and Datasheets

KÖSTER Repair Mortar Plus
  • Hydrophobic and water proofing.
  • fast setting repair mortar which is resistant to pressurized water.
  • slightly expanding repair mortar with excellent adhesion
  • it can be used as a PCC (polymermodified cement concrete) mortar.

KÖSTER Polysil TG 500
  • A primer for mineral substrates before waterproofing with cementitious waterproofing slurries for the protection of mineral substrates.
  • In case of masonry restoration, the product is used during substrate preparation for restoration plaster systems in order to harden the substrate and immobilize salts.
  • KÖSTER Polysil TG 500 is a low viscous.
  • substrate solidifying.
  • On salt containing and moist substrates.
  • it causes a reduction of the pore volume and thereby prevents the renewed formation of salt efflorescence.

KOSTER NB Elastic Grey
  • Cement base.
  • Abrasion resistant
  • waterproofing.
  • Suitable for moist surfaces.
  • Elastic.
  • Resistant to foot traffic.
  • Suitable for mineral substrates such as
