Lanko Flexible Sika – Multi-purpose deformable adhesive – 25 Kg – White

Lanko flexible from Sika is a multi-purpose construction product used primarily for waterproofing structures while offering a degree of flexibility to adapt to substrate movements. This product is part of Sika’s Lanko range, which is well known for its innovative and high-performance solutions in the field of construction materials. Lanko flexible, in particular under the reference Lanko 502 Flexible Coating, is a two-component waterproofing coating designed to offer effective protection against moisture and water while guaranteeing resistance to cracking, thanks to its flexibility.

Technical specifications and composition

Sika’s Lanko flexible consists of two components: a powder (hydraulic binder) and a polymer liquid. This two-component formula allows

to obtain a highly effective, long-lasting mix. To apply it, these two components must be mixed in specific proportions, generally with water, following Sika’s recommendations to guarantee the homogeneity and effectiveness of the coating.

This product is characterised by its ability to maintain a high degree of flexibility, even after drying. This allows it to follow the movements of the substrate to which it is applied, an essential feature for preventing the appearance of cracks due to mechanical or thermal stresses. This flexibility is particularly useful in areas subject to vibration, thermal variations or small structural movements, such as terraces, balconies or buried walls. In addition, it has good resistance to freeze/thaw cycles, making it ideal for outdoor use, even in harsh climates.

Performance Properties

One of the strengths of Lanko flexible is its ability to provide a watertight barrier while remaining impermeable even under moderate pressure. This makes it particularly suitable for areas subject to constant humidity or low water pressure, such as buried foundations, basement walls or shallow basins. Waterproofing is ensured thanks to a specific formulation that prevents water infiltration while allowing a degree of flexibility. This means it can be used for structures that are subject to small movements or temperature stresses.

Lanko flexible can also be applied directly to various types of substrate such as concrete, mortar, masonry and even some metal surfaces, provided that these are properly prepared before application. In addition, it is particularly effective for repairing damaged areas or localised cracks on old surfaces, while guaranteeing a long-lasting repair. This feature makes it a popular product for renovating or rehabilitating existing structures.

 

Practical applications

Lanko flexible is commonly used in a wide range of construction and renovation applications:

1. Waterproofing terraces and balconies : One of the main uses of Lanko Flexible is for waterproofing horizontal surfaces exposed to damp, such as terraces, balconies and roofs. Its adhesion and flexibility make it an ideal solution for preventing water from penetrating building materials and causing deep structural damage.
2. Buried walls and foundations: Used to protect buried walls against damp, this product prevents water from seeping into foundations and protects structures against the risks of rising or lateral damp. It is particularly effective in basements and for waterproofing the outside walls of cellars.
3. Ponds, swimming pools and water tanks : Lanko Flexible is also suitable for waterproofing concrete pools and ponds, guaranteeing long-term impermeability even in direct contact with water. What’s more, its flexibility ensures that it resists the cracks that materials can suffer over time.
4. Local repairs : This product is commonly used for local waterproofing repairs, particularly in the case of small cracks or areas where moisture has caused damage. Its flexibility means that repairs last longer.

Advantages and Benefits

Lanko Flexible offers a number of advantages. Firstly, it provides protection against moisture and is particularly effective in areas susceptible to water ingress. Its flexibility is another major advantage, allowing it to adapt to structural movements without cracking, which is crucial in constructions subject to mechanical stress. What’s more, it is extremely weather-resistant, including freeze/thaw cycles, so it can be used in a variety of environments and under difficult climatic conditions. It is also easy to apply, using simple tools such as rollers or spatulas.

In summary, Sika Lanko Flexible is a high-performance product for waterproofing and repairing structures exposed to moisture. Thanks to its two-component formula, flexibility and resistance, it has a wide application in many construction sectors. Its effectiveness, durability and ability to protect against water ingress, while at the same time being able to follow the movements of structures, make it an indispensable solution in many construction and renovation projects.
