SikaLatex® SBR – Versatile Polymer for Superior Mortar Performance

At Build Materio, we proudly offer SikaLatex® SBR, a premium styrene-butadiene rubber (SBR) emulsion designed to elevate the quality of cement-based mixtures. Whether enhancing adhesion, waterproofing, or flexibility, this multipurpose additive delivers reliable results across a broad spectrum of construction applications.

Key Benefits

• Enhanced adhesion—creates stronger bonds between cementitious materials and substrates.
• Waterproofing—boosts resistance to moisture ingress and water vapor.
• Toughness & Flexibility—reduces cracking and improves structural durability under stress.
• Improved chemical and frost resistance—ideal for exposed or harsh conditions.
• Lower viscosity and water requirement—achieves better workability with less water.
• Multipurpose—suitable for renderings, mortars, grouts, screeds, tile fixings, and more.

Ideal Applications

• Bonding layers in rendering, plastering, and coating.
• Keying fresh concrete to old surfaces.
• Tile fixing and panel installations.
• Cementitious grouting, screeds, and polymer-modified repair mortars.
• Waterproof plastering on roof slabs, basements, water tanks, retaining walls, etc.
• Addressing saltpetre and efflorescence in masonry.

Technical Highlights

• Product Form: Milky white SBR emulsion.
• Specific Gravity: ~1.02; pH: ~8 ± 1.
• Tensile Adhesion Strength: ≥ 1.5 N/mm² (concrete failure)
• Packaging Options: 250 g, 500 g, 1 kg, 5 kg, 10 kg, 20 kg, 100 kg
• Shelf Life: 18 months when stored between +5 °C to +35 °C (avoid frost and direct sun)

Application Guidelines

1. Ensure substrate is solid, clean, and free of dust or contaminants.
2. Pre-wet cementitious substrates until damp but not standing water.
3. Mix SBR with water, then add cement (and sand if required), stirring to achieve a smooth consistency.
4. Apply according to intended use: thin coats for waterproofing or bonding; thicker layers in multiple passes for mortar.
5. Protect and cure using wet burlap, polyethylene sheets, or misting for 3–5 days.
6. Clean tools with water immediately after use; dried material must be removed mechanically.
