CERESIT CR90 Crystaliser is a crystallizing coat, a cement combination with mineral fillers and additives, used for waterproofing non-deformable, crack-free mineral substrates such as concrete, brick-work, renders and screeds.
CR 90 works in two ways – it forms a waterproofing layer on the surface of the substrates and additionally, during the structure exploitation, it builds crystals in the substrate’s pores.
Water-insoluble salts penetrate into the capillary structure of the concrete, where – through the contact with water – they gradually build up the crystals.
This crystal formation process leads in time to the complete closure of capillarity routs, which finally eliminates the water transport in the concrete, in both directions.
Therefore crystallization can be seen as an additional protection of the substrate in case of the local damage of the coat or break caused by the initiation of the static cracks.

Advantages:
- Waterproofing through crystallization
- Resistant to positive and negative water pressure
- Seals hairline cracks in the concrete structure up to 0.4 mm
- Vapour-open and frost resistant
- Cooperates with the sealing tape
- Frost resistant
- Economical application
- Can be applied by brush or trowel

Uses:
For waterproofing and damp-proofing of
- Νon-deformable mineral substrates
- Balconies
- Underground parts of the buildings including basement walls
- Sewage treatment plants
- Water tanks (including drinking water tanks) with a water depth up to 15m
- Fire tanks
- Small monolithic swimming pools up to 20m²
- Concrete and reinforced concrete, brickwork with full-joints and mineral plasters.
- It can be applied from the possitive (up to 15 m) as well as the negative (up to 5 m) water pressure side
