6. Protection of the waterproofing layer: Drainage Sheet .


1 cleaning and grinding for the substrate.
2 .Apply koster poly sill TG 500, to consolidate, strengthen, and to protect mineral substrates and to reduce their absorbency and increase adhesion.
3. using KB Flex 200 for waterproofing pipe penetration.
4. using koster repair mortar plus for the installation of fillets.
5. Apply two layers of KOSTER NB Elastic Grey as a water proofing layer.
6. using glass fiber mesh between the two layers to reduce the danger of cracking.

Materials and Datasheets

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. 

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.

KÖSTER KB-Flex 200
  • Sealant for pipe and cable penetrations even in the case of pressurized water.
  • 1-component.
  • permanently plastic material ،can therefore be directly applied from the cartridge – even in the case of flowing water.
  • Excellent adhesion to multiple substrates.
  • Easy application.
  • Horizontal and vertical (overhead) applications are possible – Irregular shapes can be sealed.
  • Good chemical resistance.
  • Resist water pressure.

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 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.
