Sika SikaBond SBR 2.5L Waterproof Bonding Agent (873668)

Sika SikaBond SBR 2.5L Waterproof Bonding Agent

Ref: SIKASBR2 | MPN: 873668 | Barcode: 5029347613624

This 2.5L format is designed for smaller-scale work, offering better control over usage and helping to reduce waste compared to larger containers. It is well-suited to patch repairs, smaller rendering jobs, and other targeted applications where consistent performance is required.

Note: This product replaces Feb® Febond SBR and Sika SBR+ as part of the Sika rebrand.

Key Performance Benefits

• Improved Adhesion: Helps create a reliable bond between new mortar and existing concrete or masonry.
• Reduced Shrinkage: Helps minimise cracking during curing.
• Water Resistance: Reduces permeability in cement-based materials.
• Enhanced Durability: Improves flexibility and supports longer-lasting performance.

Typical Applications for Smaller Jobs

• External rendering and screeds requiring improved durability.
• Bonding new mortar to existing concrete substrates.
• Patch repairs and small-scale concrete restoration work.
• Improving adhesion in tile-fixing mortars.

For applying mortar neatly into joints, use a mortar pointing gun.

Quick Application Guide

Ensure surfaces are clean, sound, and free from dust, grease, and loose material before application.

• Priming: Mix 1 part SBR with 3 parts clean water.
• Bonding Slurry: Mix with cement to a smooth, workable consistency.
• Admixture: Add directly to mortar or screed mixes as required.

Helpful Tools

For those using 2-part resin-based epoxy grouts alongside masonry work, a mixing nozzle helps ensure a consistent blend and finish.

SBR admixtures are widely used to improve the performance of cement-based materials where stronger bonding, reduced permeability, and improved durability are required. The 2.5L size offers a practical option for smaller or more controlled applications without compromising on performance.

• Product FAQs

  Q: What is the 2.5L size best used for?
  A: The 2.5L size is ideal for smaller projects, patch repairs, and controlled applications where reduced waste and precise mixing are important.
  Q: Can this be used as a bonding slurry?
  A: Yes, it can be mixed with cement to create a bonding slurry for joining new mortar or concrete to existing surfaces.
  Q: Does it improve resistance to cracking?
  A: Yes, it helps reduce shrinkage during curing, which lowers the risk of cracking in cement-based materials.
  Q: Is it suitable for external use?
  A: Yes, it improves water resistance and durability, making it suitable for external renders, screeds, and exposed applications.
  Q: Can it be added directly to mortar mixes?
  A: Yes, it is commonly used as an admixture to enhance adhesion, flexibility, and overall performance of mortar and screed mixes.
  Q: What surfaces can it be applied to?
  A: It is suitable for use on concrete, brickwork, masonry, and other cement-based substrates where improved bonding is required.
