1L SBR Bonding Agent & Waterproof Admixture - 4-in-1 Concrete Sealer, Plaster Primer & Mortar Additive for External Render, Floor Screed, Damp Proofing & Crack Prevention

100% WATERPROOF & DAMP-PROOF: Unlike PVA which breaks down when wet, SBR is completely water-resistant once cured. Perfect for high-humidity areas, external walls, wet rooms, and surfaces subject to continuous water contact. 4-IN-1 MULTI-PURPOSE FORMULA: A highly versatile polymer that functions as a high-strength bonding slurry, structural admixture, substrate sealer, and primer. One bottle covers multiple stages of your project. MAXIMUM ADHESION & WORKABILITY: Dramatically improves the "grab" and wet adhesion of mortar, making vertical and overhead applications incredibly easy. Provides a smooth, creamy texture with extended working time for a flawless finish. ANTI-CRACK & ANTI-SHRINK: Enhances the flexibility and elasticity of cement mixes. By accommodating thermal expansion and minor structural movement, it actively prevents drying shrinkage, cracking, and surface dusting. HEAVY-DUTY WEAR RESISTANCE: Reinforces concrete, floor screeds, renders, and patching mortars. Significantly boosts structural durability, tensile strength, and resistance to abrasion and mild chemicals in high-traffic areas.
