Waterproofing of B12 and B5 Building wall and chajja at back side of building at GSL Colony

Surface Preparation, crack treatment:- Remove laitance, weak layers, and contaminants using grinder or appropriate tools. Clean thoroughly using wire brushing and pressure washing to remove dust, dirt, algae, and loose particles. Ensure substrate is sound, dry, and free from oil, grease, curing compounds, or any material affecting adhesion. Identify and open cracks in V-groove profile. Fill cracks up to 5 mm width with Crack Fix Powder mixed with acrylic bonding agent to form a paste. Waterproofing coating:- Acrylic Bonding Agent & Cement Slurry Coating  Providing and applying two (2) coats of Upgrade Bonding Agent ACR- acrylic bonding agent and cement slurry on the prepared surface. Mixing Ratio: Upgrade ACR: Water : Cement = 1 : 1 : 3 (by volume). Application to be carried out uniformly using brush or roller to ensure effective bonding, pore sealing, and surface consolidation. Drying Interval: Allow 4–6 hours between coats or before application of subsequent waterproofing systems. Acrylic Waterproofing Coating  Providing and applying two (2) coats of Upgrade Raino-singlecomponent, acrylic-based, ready-to-use waterproofing membrane suitable for exterior applications. The coating shall be UV-resistant, weather-resistant, and elastomeric, forming a continuous and seamless waterproof barrier. Application to be done uniformly using brush or roller to achieve proper adhesion and complete surface coverage. Drying Interval: Allow 4–6 hours between coats or as recommended by the manufacturer. Including all labour , material and scrap folding complete.
