Complete removal of existing paint, loose coatings, dust, dirt, laitance, weak surface layers, projections and other foreign matter from walls, ceilings, facias, cornices and other architectural features by mechanical sanding using electrically operated orbital/random orbital wall sander fitted with integrated vacuum dust extraction system, having minimum operating speed of 1500 RPM and equipped with 180 mm (7") or 225 mm (9") diameter sanding pads using 80-grit abrasive discs or as required, including cleaning of surface, collection and disposal of debris, protection of adjoining finished surfaces and making the substrate smooth, sound, dust-free and ready to receive subsequent putty, primer and paint system, complete in all respects as per manufacturer's specifications and directions of Engineer-in-Charge. | 19420.00 | Sqm |
| 2 | M&L for 2.0 mm average thickness exterior grade waterproof white cement-based wall putty on prepared exterior plastered/old painted wall surfaces, comprising cleaning and preparation of the substrate to remove dust, loose particles, chalking and other contaminants, mixing the putty powder with clean potable water in proportion recommended by the manufacturer to obtain a smooth homogeneous paste, applying the first coat uniformly by airless spray equipment and allowing it to dry adequately, followed by application of the second coat or additional coat(s) as required to achieve a total average finished thickness of 2.0 mm, allowing the putty to dry completely, and thereafter sanding the surface to obtain a smooth, level, uniform and defect-free finish suitable for application of exterior acrylic primer and subsequent exterior acrylic emulsion paint system, including all labour, materials, tools, tackles, machinery, scaffolding, wastages, leads and lifts, complete in all respects as per manufacturer's specifications and directions of Engineer-in-Charge. | 20870.00 | Sqm |
| 3 | M&L for one coat of premium acrylic water-based exterior wall primer of approved make over properly prepared, repaired, puttied and dried exterior surfaces, including cleaning and preparation of the surface, thinning with clean water as recommended by the manufacturer, application by airless spray equipment to achieve uniform coverage, substrate sealing and adhesion promotion, allowing adequate drying, and preparing the surface for subsequent coats of exterior acrylic emulsion paint, complete with all labour, materials, equipment, scaffolding and incidental works, as per manufacturer's specifications and directions of Engineer-in-Charge. | 20870.00 | Sqm |
| 4 | M&L for two or more coats of premium acrylic smooth exterior emulsion paint of approved shade and finish having superior weather resistance, UV resistance, colour retention, silicon additive technology, excellent dirt pick-up resistance, anti-algal and anti-fungal properties and VOC content not exceeding 50 g/L in compliance with LEED requirements, over properly prepared, puttied and primed exterior surfaces, including thorough stirring and dilution with clean potable water as per manufacturer's recommendations, application of the first coat uniformly by mechanical roller and airless spray equipment, allowing adequate drying, followed by application of the second or additional coat(s) as required to achieve uniform opacity, colour consistency and finish, and completing the work to a smooth, even, streak-free, lap-mark-free and durable weather-resistant surface, including all labour, materials, tools, tackles, machinery, scaffolding, wastages, leads and lifts, complete in all respects as per manufacturer's specifications and directions of Engineer-in-Charge | 20870.00 | Sqm |
| 5 | M&L for 15mm thick rendering cement plaster in cement mortar (1:4) on any faces of brick walls or concrete surfaces, finished even and smooth without using extra cement complete all as specified and directed. | 1450.00 | Sqm |
