Addibond SBR
Addibond SBR
Addibond SBR is a heavy-duty Styrene Butadiene Rubber latex emulsion specially engineered to enhance cementitious mortars and structurally bond fresh to old concrete.
Technical Property | Official Certified Value | Engineering Benefit |
Polymer Base | Styrene-Butadiene Latex Emulsion (SBR) | Provides maximum bonding adhesion and flexural strength |
Waterproofing Shield | Micro-Pore Sealing & Hydrophobic Action | Prevents water penetration and chloride ion intrusion |
Stress Tolerance | Elevated Tensile & Impact Resistance | Absorbs structural vibrations and dynamic thermal stresses |
Shrinkage Control | Shrinkage Reduction Formula | Prevents map cracking and debonding in plaster/renders |

Structural Bonding Performance: Creates an indestructible bond between old concrete foundations and new overlays.
Low Permeability: Provides exceptional resistance against water penetration and corrosive chemical salts.
Flexibility & Elasticity: Absorbs thermal expansion without cracking, ensuring structural integrity.
Corrosion Protection: Protects embedded steel reinforcement by acting as a barrier against moisture and salts.
Slurry bonding agent (wet-on-wet method) for casting new concrete onto mature substrates.
Spatter-dash (Key coat) polymer modifier for application on fair-faced and shear wall surfaces.
Structural repair mortars, patching mortars, chamfer fillets, and angle bead joints.
Bedding mortars for tiles, marble, and heavy stone cladding exposed to water across Egypt.
Substrate Preparation: Thoroughly clean concrete substrates of dust, oil, and laitance, then pre-wet to achieve a Saturated Surface Dry (SSD) condition.
Slurry Preparation: Mix Addibond SBR with neat cement and water according to technical mixing ratios until a uniform slurry is obtained.
Application Method: Apply the slurry using a stiff bristle brush or roller, then place fresh concrete or mortar immediately while the slurry layer remains wet.
