Overview:

Sika SikaBond SBR + Waterproof Bonding Agent 2.5 Litre is a multi-purpose SBR latex designed to improve bonding and water resistance in cement-based mixes. Use it as a primer/bonding coat between old and new surfaces, or as an admixture to enhance mortars, screeds and renders for better adhesion, flexibility and reduced permeability.

Ideal for internal and external work, it’s particularly useful where moisture is a concern, helping deliver tougher, longer-lasting finishes on concrete, masonry and plaster backgrounds. Supplied as a white liquid in a handy 2.5L size for easy handling on site.

Sika SikaBond SBR+ PLUS Waterproof Bonding Agent 2.5L – Key FAQs

• What is SikaBond SBR used for?
  It’s used as a bonding coat/primer or as an admixture in mortars, screeds and renders to improve adhesion, water resistance and overall durability on building substrates.

• Can I use this as a primer before rendering or screeding?
  Yes, it can be used to prime and improve bonding to suitable backgrounds, helping new cement-based layers key properly and reducing issues on porous or dusty surfaces.

• Is it suitable for internal and external use?
  Yes, it’s suitable for both internal and external applications, including areas where moisture is present, provided the correct system and preparation are followed.

• Does it help reduce cracking in cement mixes?
  Used as an admixture, it can improve flexibility and reduce shrinkage-related cracking, helping cement-based materials perform better in demanding conditions.

• What materials can it be used with?
  It’s commonly used with cement-based mixes such as mortars, screeds, renders and repair compounds, and on substrates like concrete, masonry and plaster.

• Do I need to check a datasheet before use?
  Yes always read the Technical Datasheet before first use to confirm suitability, correct dilution/mix ratios, coverage expectations and application guidance for your specific job.
