Materials and Datasheets

KOSTER 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.

KOSTER 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
    concrete and brick walls.
  • Can be use for under tile. 

KOSTER Glass Fiber Mesh

• Highly tear resistant mesh for the reinforcement of waterproofing layers
• Reduce the danger of cracking as well as connections, wall/floor junctions, and fillets.
• Resistant to dislocation.
• plasticizer-free.
• resistant to alkalis.

KOSTER Superfleece

• High strength polyester nonwoven reinforcement fabric for liquid waterproofing products. To reinforce waterproofing in corners and other areas prone to cracking
• to connect to gutters, gullies, and similar custom details.
