SikaTop 121

SikaTop 121 is a high-performance, two-component, cementitious, polymer-modified mortar. It is designed for use as a waterproofing and protective coating on concrete and masonry surfaces. With superior adhesion and durability, SikaTop 121 can be applied to both vertical and horizontal surfaces, providing an effective solution for preventing water ingress and enhancing the overall longevity of structures. The product is suitable for use in areas exposed to harsh weather conditions, aggressive chemicals, and high moisture.

Usage:

SikaTop 121 is typically used in the following applications:

1. Waterproofing Concrete and Masonry Surfaces: Ideal for areas that are regularly exposed to water, such as basement walls, foundations, and sewage treatment plants.
2. Protective Coating: Provides a durable, protective layer for concrete structures in marine environments, roofs, and tunnels.
3. Surface Restoration: Used to repair and protect deteriorated or worn concrete surfaces, offering a smooth finish with enhanced resistance to abrasion.
4. Barrier for Aggressive Environments: Helps protect concrete surfaces from the adverse effects of chlorides, acids, and other corrosive substances.
5. Balconies and Terraces: Suitable for waterproofing and enhancing the structural integrity of balconies and terraces.
6. Internal and External Applications: Can be used on both internal and external surfaces of buildings and civil structures.

Advantages:

1. Excellent Adhesion: Forms a strong bond with concrete and masonry substrates, ensuring long-lasting protection and durability.
2. Waterproofing: Effectively prevents water ingress, making it ideal for basements, foundations, and other wet areas.
3. Chemical Resistance: Resistant to a variety of chemicals, offering protection in industrial settings or environments exposed to harsh substances.
4. Easy to Apply: The product is easy to mix and apply, even on vertical surfaces, providing a smooth, uniform finish.
5. Durability: Resistant to mechanical wear, abrasion, and weathering, making it suitable for long-term applications in both internal and external environments.
6. Flexible: Provides crack-bridging properties, accommodating small surface movements and enhancing the overall durability of the coating.
7. Cementitious and Polymer-Modified: The unique combination offers a strong and flexible waterproof barrier with improved mechanical properties compared to standard mortars.
8. Fast Drying: Offers quick setting times, allowing for rapid application and project completion.
9. Non-toxic and Safe: When mixed and applied correctly, SikaTop 121 is safe for use in various environments without the risk of harmful emissions.

Applications:

1. Construction: Used in new constructions, especially in areas that require waterproofing, such as foundations, below-grade walls, and terraces.
2. Renovation Projects: Ideal for restoring and protecting old, damaged concrete surfaces, particularly in areas exposed to water or chemicals.
3. Industrial Facilities: For coating and protecting concrete surfaces in factories, warehouses, and other industrial environments.
4. Marine and Coastal Structures: Used in the protection of concrete exposed to seawater or other corrosive environments.
5. Underground Construction: Applied to underground structures like tunnels and underground car parks to prevent water penetration and corrosion.
