Bond It – SBR Admixture Waterproof Bonding Agent 25 Litre (BDH041)

Bond It SBR Admixture, Waterproof Bonding Agent 25 Litre

MPN: BDH041

Barcode: 5060021361202

This 25-litre Bond It SBR Admixture enhances the performance of cementitious materials for internal and external use, improving adhesion, flexibility, and water resistance.

Who This Product Is For

This product serves contractors and individuals undertaking construction or repair work involving cement-based materials. It suits those working on projects requiring improved bonding, waterproofing, or surface preparation.

The admixture addresses tasks where enhanced adhesion between surfaces is needed, or where water resistance and reduced cracking in cementitious mixes are priorities.

Key Features

• Enhanced Adhesion: Bonds to various surfaces including dense concrete, steel, and tiles.
• Improved Flexibility: Reduces cracking and shrinkage in cementitious materials.
• Waterproofing Properties: Provides resistance against water and vapour.
• Chemical Resistance: Performs in chemically harsh environments.
• Multiple Functions: Works as an admixture, primer, sealer, or bonding agent.
• Minimises risk of cracking and surface dusting.
• Extends lifespan of repairs and constructions.
• Simplifies preparation and application processes.
• Provides consistent results in challenging conditions.

Practical Applications

• Waterproofing floors and walls exposed to moisture.
• Creating bonds between new and old concrete during renovations.
• Repairing worn or damaged screeds.
• Priming low-porosity substrates before tiling or rendering.
• Patching concrete or preparing surfaces for granolithic flooring.

How This Fits Into a Typical Job

This product integrates into construction workflows during surface preparation and mixing stages. It is typically used before applying final coatings or renders to improve bonding and performance.

For waterproofing tasks, it forms part of a multi-coat system applied before rendering. In bonding applications, it creates a key coat between substrates and subsequent layers.

Application Instructions

1. Surface Preparation: Ensure surfaces are free from oil, grease, laitance, and loose debris. Scabble unsound areas to a solid base if needed.
2. Mixing Key Coat: Combine one part SBR with two parts cement by volume, adjusting with water to reach brushable consistency. Stir thoroughly.
3. Application of Key Coat: Brush mixture onto substrate with thorough coverage. Apply subsequent flooring or rendering layer while still wet.
4. Damp-Proofing: Apply three coats at alternating angles, allowing each to dry before next. Apply render while final coat remains wet.
5. Mortar Preparation: Add 5–7.5 litres of SBR per 25kg of cement when mixing sand cement mortar or render, reducing water accordingly. Apply at least 6mm thick.
6. Flooring Applications: Mix SBR with cement, sand, and granite chips for granolithic floors, adjusting quantities based on thickness.
