Polymer emulsion modified, cement based, dual component crystalline waterproofing mortar
resistant to sulfate, chlorine and Chemicals,
which can be applied against negative and positive water pressure.
CRS SİSTEM-2K reacts with the chemicals in the concrete to produce crystals and clog the
capillary spaces in the concrete. Thanks to this feature, it
provides the final solution in waterproofing applications made from both negative and
positive sides.
General Characteristics
It is resistant to both positive and negative water pressure. In addition
to crystallizing and penetrating the concrete, it forms a flexible and
durable layer on the surface, providing two-level protection. It is a twocomponent
product (the powder component and liquid component are
mixed and applied). It is hygienic and suitable for use in the waterproofing
of drinking water tanks. It does not contain soda or chloride and protects
the reinforcement in concrete from corrosion. It is capillary active.

Packaging: A: 25 kg Kraft B: 3 kg Canister The product should be stored in a clean, dry, and moisture-free environment, between +5°C and +35°C, away from direct sunlight. It must be protected from water, freezing, and severe weather conditions. It should be stacked a maximum of 10 layers high. Provided the specified storage conditions are followed, the shelf life is a maximum of 12 months from the production date.
During application and mixing, contact with skin and eyes should be avoided. In case of contact, wash immediately with plenty of water. If contact with eyes occurs, rinse thoroughly with water and seek medical attention. Protective gloves, clothing, mask, and goggles should be worn during use.
Surface Preparation - The surfaces to be applied should be damp; dry surfaces should be moistened before application. The moistening process should be done 1 day before and again 2 hours prior to application by fully saturating the surface with water. Ensure that there are no water pools on the surface. CRS SYSTEM-2K – Before application, the surface must be free from dust, oil, paint, curing agents, and other materials that may interfere with penetration. If necessary, the surface should be roughened to allow for proper adhesion. Mixing: Mix 3 kg of Component B (liquid) with 5-6 liters of clean water in an appropriate container. During mixing, Component A (powder) should be slowly and continuously added to the liquid mixture. After adding one bag (25 kg) of powder component, continue mixing for at least 3 more minutes. The mixing process should be carried out with a low-speed mixer until the mixture becomes completely homogeneous. Application: CRS SYSTEM-2K is applied using a brush or suitable spraying equipment. Apply in 2 or 3 coats. Each layer should be applied homogeneously and evenly, with each coat applied in the same direction. Allow sufficient drying time between coats (at least 3 hours), but no more than 24 hours should pass before the next layer is applied.
