CERESIT CR 90
Crystalizing waterproofing coat for waterproofing of buildings and structural components
For waterproofing buildings and structural components forms a waterproofing layer on the substrate of the substrates and additionally, during the structure exploitation, it builds crystals in the substrate pores.
-
Waterproofing through crystalisation (vapour open + frost resistant)
-
Resistant to positive and negative water pressure
-
Seals hairline cracks in the concrete

CERESIT® CR 90 is used for waterproofing 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. CR 90 allows a proper cooperation with the CERESIT CL 152 Sealing Tape on the connections between walls and floor and expansion joints. CR 90 can also be applied on corners combined with with CERESIT CL 56, CERESIT CL 57 and CERESIT CL 5.Available pack size: 25kg

Substrates must be smooth, absorbent and porous. Dirt, existing layers of low resistance and all previous paint coverings, lime plasters, and substances that impede adhesion must be carefully removed. Corroded joints should be removed up to the depth of 2 cm and refilled with cement mortar. Deep holes and uneven substrates should also be repaired with cement mortars or concrete. CERESIT CR 90 requires the pre-wetting of the substrates before application to the mat-wet conditions.
Sprinkle CERESIT CR 90 into clean, cold water and mix (using a mixer) until the homogenous mass without lumps is obtained:– for brush application – use 8 l water per 25 kg CR 90,– for trowel application – use 6 l water per 25 kg CR 90.The layer should be applied on the damp but not wet substrate. The first layer of CR 90 should be applied crosswise with a brush, the second layer can be applied by brush or a trowel.
Do not mix with other materials, additives or binders. Before finishing the application check if the required thickness of CERESIT CR 90 is achieved. Use CR 90 only in dry conditions and at temperatures ranging from +5°C to +25°C. All the data refer to the temperature of +23°C and relative humidity of 55%. Please note that under other climatic conditions hardening can be accelerated or delayed.
