What is SikaTop 122?
SikaTop 122 is a two-component, cement-based mortar that is designed for surface repair, protection, and refurbishment applications. It consists of a powder component (Component A) and a liquid component (Component B), which, when mixed together, form a highly effective and durable bonding layer. The mortar is known for its excellent adhesion to concrete, its resistance to water and weathering, and its high compressive and flexural strength.
The product is typically used for repairing concrete surfaces, resurfacing worn-out or damaged substrates, and providing protective coatings against aggressive environmental conditions. It is suitable for both interior and exterior applications and can be used in a variety of construction environments, from residential buildings to industrial structures.
Key Features of SikaTop 122
SikaTop 122 stands out in the market due to its unique combination of features that make it a go-to choice for construction professionals. Here are some of its key attributes:
High Bond Strength
One of the most important qualities of SikaTop 122 is its exceptional bond strength. When applied to concrete, it forms a solid and durable bond, which is crucial for ensuring the longevity and stability of the repair or protection. This bond strength makes the product ideal for resurfacing and patching concrete surfaces that may have suffered from wear and tear, cracking, or other types of damage.
Excellent Durability
SikaTop 122 is known for its long-lasting performance. It is highly resistant to mechanical stresses, wear, and exposure to harsh weather conditions. It can withstand freezing and thawing cycles, high humidity, and even exposure to chlorides, making it ideal for use in coastal or marine environments where saltwater and other aggressive chemicals might otherwise cause significant damage.
Waterproofing Properties
Another standout feature of SikaTop 122 is its excellent waterproofing capabilities. It acts as a protective barrier against water penetration, making it especially suitable for applications in areas prone to moisture, such as basements, underground structures, and swimming pools. The waterproof nature of the product also helps in protecting the underlying concrete from the harmful effects of water ingress, including corrosion and deterioration.
Resistance to Chemicals
In addition to its waterproofing properties, SikaTop 122 is resistant to a wide range of chemicals, including mild acids, alkalis, and oils. This makes it highly effective for use in industrial environments where surfaces are exposed to chemical spills or cleaning agents, such as factories, warehouses, and storage facilities.
Versatility in Application
The versatility of SikaTop 122 allows it to be used in numerous applications, both as a repair material and a protective coating. It can be used for surface leveling, patching cracks, filling holes, resurfacing floors, and as a bonding agent for tiles and other finishing materials. It is easy to apply, even for those with limited experience in construction work.
User-Friendly and Easy to Apply
SikaTop 122 is a user-friendly product that is easy to mix and apply. Its consistent consistency and smooth finish ensure that it can be spread evenly across surfaces, allowing for a seamless application process. Furthermore, it offers sufficient working time for adjustments and corrections during the application phase.
Applications of SikaTop 122
The versatility of SikaTop 122 makes it suitable for a wide range of applications in both new construction and maintenance projects. Below are some of the most common uses:
Concrete Surface Repair and Renovation
SikaTop 122 is commonly used to repair and renovate damaged or worn-out concrete surfaces. It can be applied to restore structural integrity to concrete substrates that have been compromised by cracking, spalling, or surface erosion. The product effectively fills gaps and voids, providing a smooth and even finish that restores the aesthetic appearance and functionality of the surface.
Protection of Concrete Structures
In addition to its repair capabilities, SikaTop 122 is also used as a protective coating for concrete surfaces. It serves as a protective barrier against moisture, chemicals, and environmental stress, preventing the degradation of the underlying concrete. This makes it ideal for use in aggressive environments, such as marine structures, sewage systems, and parking garages.
Waterproofing
As a waterproofing solution, SikaTop 122 is often applied to basements, swimming pools, terraces, and other exposed surfaces to prevent water ingress. It helps to seal the substrate and protect it from the damaging effects of water. This feature is especially beneficial in regions with high rainfall or where structures are frequently exposed to water and humidity.
Tile Bonding
SikaTop 122 can be used as a bonding agent for the installation of tiles and other finishing materials. Its strong adhesion properties make it an ideal substrate for laying tiles in areas where regular cement-based adhesives may not provide sufficient bond strength. It is particularly useful for outdoor tiling applications where additional protection against weathering is required.
Floor Resurfacing
For floors that are subjected to heavy traffic, SikaTop 122 can be used to resurface and level the existing concrete slab. It provides a smooth and even surface that is resistant to abrasion and wear, extending the lifespan of the floor. It is commonly used in industrial facilities, warehouses, and public buildings.
Benefits of Using SikaTop 122
There are several compelling reasons why contractors and builders turn to SikaTop 122 for their construction and renovation projects. Some of the key benefits include:
Enhanced Longevity
The durability of SikaTop 122 ensures that it provides long-lasting protection for concrete surfaces. This reduces the frequency of maintenance and the associated costs, making it a cost-effective solution for large-scale and long-term projects.
Cost-Effectiveness
Despite being a high-performance material, SikaTop 122 is relatively affordable compared to other specialized repair and protective products. It is designed to offer high value for money by extending the lifespan of concrete structures and reducing the need for frequent repairs or replacements.

Application Instructions for SikaTop 122
Proper application of SikaTop 122 is essential for achieving the best results. Below is a general step-by-step guide to using the product:
Surface Preparation
Before applying SikaTop 122, ensure that the surface is clean, dry, and free of dust, oils, grease, or any other contaminants. It is important to prepare the substrate by removing any loose or deteriorated material. For concrete surfaces, it may be necessary to roughen the substrate to improve the adhesion of the mortar.
Mixing
To mix SikaTop 122, combine the powder component (Component A) with the liquid component (Component B) in the recommended ratio. Stir the mixture thoroughly until a smooth, lump-free consistency is achieved. Avoid mixing more material than can be used within the working time (usually around 30-45 minutes).
5.3 Application
Using a trowel or other suitable tools, apply the mixed mortar to the prepared surface. For larger surfaces, it is important to apply it in layers to achieve a uniform finish. Ensure that each layer is smooth and free from air pockets.
5.4 Curing
Allow the applied material to cure for the recommended period, usually 24-48 hours, depending on the temperature and humidity. Proper curing is essential for achieving the full strength and durability of the product.
Conclusion
SikaTop 122 is a high-performance cementitious mortar that offers a range of applications, from surface repair and renovation to waterproofing and protection.
