Specification data - Crystallization active slurry mortars

Additive

Not required.

Köster NB 1 Flex.

Guidance for specification option:

  • A latex based dispersion which is intended as a mixing liquid for Köster NB sealing slurries.
  • It has an elastifying effect, improves the adhesion to the substrate and prevents the premature drying out of the fresh slurry.

Köster SB-Bonding Emulsion.

Guidance for specification option:

  • Added to the mixing water to raise the ability of the waterproofing system to retain water.
  • Prevents, in cases of unfavourable weather conditions (warm, dry, drought), a premature curing of the coating.
  • Introduces flexibility to the material.
