CRYSTALINE ACTIVE BARRIER
JUTA UK Crystalline Active Barrier (CAB) is a crystalline cementious waterproof slurry which creates a monolithic bond to concrete structures. When mixed with clean water and and applied correctly, it is designed to form a permanent waterproof coating in accordance with BS8102:2009.
Read MoreSurface Preparation
All surfaces must be free from existing coatings or contamination i.e. paint, laitance, dirt etc. and present an open capillary structure to allow monolithic bonding of the crystalline chemicals. If the surface is dry, thoroughly dampen the the surface with water prior to application to aid adhesion.
Cracks and bolt holes must be cut out and filled solid with hydrolock paste prior to the application of CAB. Substates contaminated with high levels of soil or ground water may require the addition of salt inhibitors.
Mixing
CAB consistency can be varied to suit the application method.
Brush applied slurry or trowel application:
- Place the recommended amount of clean water into a suitable mixing bucket.
- Using a slow speed electric paddle mixer (400-600rpm), gradually start to add the powder while mixing.
- Ensure all the powder is added.
- Mix for approx. 3 minutes to achieve a creamy lump free consistency.
- If required, add a small amount of water to obtain the correct consistency depending on the application.
For spray application: use traditional wet mortar spraying equipment and processes.
CAB is a minimum two coat application system. Once mixed CAB has a 30-minute pot life at 20°C.
Normal application rate is 3kg/m2 for an overall two coat application. Consumption rates are to be increased up to 6kg/m2 for areas of excessive water pressure.
Do not apply CAB to substrates with temperatures below 5°C or if the ambient temperature is below 5°C or expected to fall below 5°C within 24 hours. Avoid application in direct sunlight.
Do not allow CAB to dry out to rapidly. After initial set, moist curing is recommended. Fine mist spray treated area 3-4 times daily for a 48-hour period. It is recommended ventilation is provided as a lack of ventilation may cause condensation to form on the surface of CAB. Protect the coating from excessively fast evaporation in hot conditions or drying winds. If these conditions prevail, fine mist spray the surface regularly.
