Fosroc Waterproofing Coating

Product Details:

Fosroc Nitocote SN522 is a high-performance, elastomeric, cementitious waterproofing coating manufactured by Fosroc, a leading provider of construction chemicals and solutions. Here's a detailed overview of this product:

1. Composition: Nitocote SN522 is a two-component, flexible cementitious waterproofing membrane. It consists of a liquid polymer component (Component A) and a cement-based powder component (Component B). When mixed together in the correct ratio, they form a smooth, elastomeric waterproofing coating.

2. Elastomeric Properties: Nitocote SN522 exhibits elastomeric properties, allowing it to stretch and accommodate minor substrate movements without cracking or delamination. This flexibility ensures long-term waterproofing protection even in areas prone to structural movements or vibrations.

3. Waterproofing Performance: Nitocote SN522 provides excellent waterproofing protection for a wide range of substrates, including concrete, masonry, plaster, and brickwork. It forms a seamless membrane that effectively prevents water ingress, dampness, and moisture penetration into the structure.

4. Breathable: Despite its waterproofing properties, Nitocote SN522 allows for the passage of water vapor, enabling trapped moisture within the substrate to escape. This breathability helps prevent the buildup of hydrostatic pressure and minimizes the risk of blistering or delamination of the coating.

5. Chemical Resistance: Nitocote SN522 offers resistance to a variety of chemicals, including mild acids, alkalis, and salts, making it suitable for use in aggressive environments such as sewage treatment plants, chemical storage facilities, and industrial floors.

6. Adhesion: Nitocote SN522 exhibits excellent adhesion to properly prepared substrates, ensuring a strong bond and long-lasting waterproofing performance. Proper surface preparation, including cleaning, priming, and leveling, is essential to maximize adhesion and coating integrity.

7. Application: Nitocote SN522 is typically applied by brush, roller, or spray equipment onto clean and sound surfaces. The two components are mixed together in the specified ratio immediately before application. The coating can be applied in multiple coats to achieve the desired thickness and waterproofing performance.

8. Curing Time: Nitocote SN522 has a relatively fast curing time, allowing for quick turnaround times and minimizing downtime during construction or renovation projects. Depending on temperature and humidity conditions, it may achieve initial set within a few hours after application.

9. Protection and Aesthetics: In addition to providing waterproofing protection, Nitocote SN522 enhances the appearance of the substrate with a smooth, uniform finish. It can be left as a standalone coating or top-coated with compatible paints or coatings for additional protection and aesthetic enhancement.

10. Versatility: Nitocote SN522 is suitable for both horizontal and vertical applications, making it suitable for waterproofing basements, retaining walls, foundations, roofs, balconies, and other structural elements. It can be used in new construction or renovation projects to address water ingress issues effectively.

11. Safety and Compliance: Nitocote SN522 complies with relevant industry standards and regulations for waterproofing coatings. It is formulated to meet stringent quality control standards and undergoes rigorous testing to ensure consistent performance and reliability.
