Features of Cementitious Surface Coating NB 1 Grey
- KOSTER NB 1 Grey is a mineral coating containing crystallising and capillary-plugging agents. It can be used for waterproofing against ground moisture, non-pressurised and pressurised water.
- Waterproofing undertaken with KOSTER NB 1 Grey is characterised by excellent resistance to pressure and abrasion as well as excellent resistance to chemicals.
- Waterproofing with KOSTER NB 1 Grey should only be carried out on substrates that are free of moving cracks.
- The addition of KOSTER SB-Bonding Emulsion Concentrate to the mixing water or respectively the use of KOSTER NB 1 Flex raises the ability of the material to retain water and prevents, in cases of unfavourable weather-conditions (warm, dry, drought), a premature curing of the coating. KOSTER SB-Bonding Emulsion Concentrate also introduces flexibility to the material.
