KÖSTER NB 1 Grey

Mineral based, sulfate resistant waterproofing system for positive and negative side waterproofing against pressurized water

Waterproofing with KÖSTER NB 1 Grey should only be carried out on  substrates that are free of moving cracks. Moving cracks should be considered construction joints and treated accordingly with KÖSTER Joint Tape, KÖSTER Injection Resins, or KÖSTER Joint Sealant FS.
KÖSTER SB-Bonding Emulsion introduces flexibility to the material.
