KÖSTER NB Super | Single Component Crystalline Waterproofing Mortar

KÖSTER NB Super

KÖSTER NB Super is a single-component, cement-based crystalline waterproofing mortar. It penetrates into the pores and micro-cracks of concrete, forming crystalline structures that permanently block water pathways. Thanks to this active technology that works beneath the surface, the waterproofing effect continues throughout the service life of the structure.

Resistant to both positive and negative water pressure, the product is suitable for interior and exterior applications. It provides an easy-to-use, low-maintenance, and long-lasting waterproofing solution.

Technical Specifications

Composition: Single-component, cement-based

Working Mechanism: Active crystallization technology

Waterproofing Performance: Resistant to positive and negative water pressure

Application Method: Brush or spray application

Suitable Surfaces: Concrete, exposed concrete, plaster surfaces

Consumption: Approximately 2–3 kg/m² (depending on surface conditions)

Advantages

Deep Waterproofing Protection:
Crystalline structures penetrate into concrete and block water channels.

Long-Lasting Performance:
The crystallization process continues in the presence of moisture, maintaining its waterproofing effect.

Resistance Against Negative Water Pressure:
Provides protection against water pressure from both internal and external directions.

Easy Application:
Its single-component structure allows fast and practical application.

Integrates with Concrete:
Instead of forming only a surface coating, it becomes part of the concrete structure.

Non-Toxic Formula:
Suitable for applications involving contact with drinking water.

Application Areas

Underground structural elements such as basements, foundations, and curtain walls

Elevator pits

Water tanks

Tunnel and channel systems

Exposed concrete surfaces

Structures exposed to water pressure from the negative side

Application Instructions

The surface must be cleaned from weak particles, dust, oil, and other contaminants, and should remain damp before application.

The product is mixed with clean water at the recommended ratio until a homogeneous consistency is achieved.

It is applied using a brush or spray method.

Drying times between layers should be observed, and curing should be performed after application.

Frequently Asked Questions (FAQ)

1. Is KÖSTER NB Super resistant to negative water pressure?
Yes. It is resistant to both positive and negative water pressure.

2. How many layers should be applied?
Generally, two layers are recommended; however, the number of layers may vary depending on surface conditions and project requirements.

3. Can it come into contact with drinking water?
Yes. It does not contain toxic substances and is suitable for applications involving drinking water contact.

4. How long does crystallization continue?
Crystal formation continues for days after application, and its waterproofing effect remains active in the presence of moisture.

KÖSTER NB Super is a professional waterproofing solution that penetrates into concrete, providing permanent, long-lasting protection against water penetration and resistance against negative water pressure.
