FAQs Sika Sikabond SBR Waterproof Bonding Agent – 25 Litre

1. What makes Sika Sikabond SBR an essential product for construction projects?
   High-performance bonding agent and admixture that significantly enhances the durability and adhesion of cement-based products. Its water-resistant formula makes it suitable for challenging environments such as wet areas or exposed outdoor surfaces. By improving flexibility and reducing the risk of cracking, it ensures long-lasting results across a wide range of applications, including rendering, screeding, and waterproofing.

2. How does the 25-litre size benefit contractors and professionals?
   The 25-litre size is specifically designed to meet the needs of large-scale projects or continuous use, providing substantial cost savings through the Money Saver Deal. This volume reduces the frequency of reordering, ensuring you have enough product on hand for extended tasks. It’s an economical solution for professionals managing high-volume projects without compromising on quality.

3. Is this product suitable for creating waterproof mortars and screeds?
   Yes, when used as an admixture, Sika Sikabond SBR PLUS enhances the water resistance of cement-based materials. This makes it ideal for creating waterproof mortars and screeds for applications such as swimming pools, bathrooms, or external walls exposed to rain and moisture.

4. Can it improve the performance of concrete repairs?
   Absolutely. Sika Sikabond SBR + increases the adhesion, flexibility, and durability of repair mortars, ensuring they bond effectively with existing concrete surfaces. Its ability to resist water and chemicals ensures the longevity of repairs in demanding conditions, making it perfect for both structural and cosmetic fixes.

5. How does Sika Sikabond SBR work as a primer?
   When diluted (typically 1:4 with water), it can be applied to porous surfaces to create a sealed and stable base for rendering, tiling, or painting. This primer layer minimizes dusting, prevents excessive absorption of subsequent layers, and enhances adhesion, resulting in a smoother and more durable finish.

6. Is this product resistant to harsh environmental conditions?
   Yes, the SBR formula provides excellent resistance to water, certain chemicals, and temperature fluctuations. This makes it suitable for a wide range of indoor and outdoor applications, including industrial and commercial projects where surfaces are exposed to heavy use or adverse weather conditions.

7. What are the advantages of using Sika Sikabond SBR in outdoor projects?
   In outdoor applications, Sika Sikabond SBR PLUS improves the durability and flexibility of renders, screeds, and adhesives, helping them withstand weather changes, UV exposure, and mechanical stress. It’s particularly effective in waterproofing external walls, repairing garden features, or creating strong bonds in outdoor construction tasks.

8. Why is Sika Sikabond SBR preferred over traditional bonding agents?
   Unlike standard PVA bonding agents, Sika Sikabond SBR + offers superior water resistance, making it suitable for wet and exposed environments. Its advanced formula also enhances the strength and flexibility of cement-based materials, reducing the likelihood of cracking or shrinkage. These properties make it a professional-grade solution for demanding projects where traditional bonding agents might fail.
