It focuses heavily on defect repair, damp-proofing up to 2m, and a complete resurfacing from rooftop to foundation to protect the structure from the elements. Phase 1: Surface Preparation & Paint RemovalScraping: Completely strip all loose, peeling, and degraded existing paint down to the raw plaster using high-pressure washing, mechanical grinders, or manual scrapers.Cleaning: Wash the walls to remove dust, dirt, and salts.Safety: Erect scaffolding or elevated platforms, as this is a double-storey building Phase 2: Crack Repair & SealingRaking Out: Widen existing cracks to allow for deep penetration of sealing materials.Sealing: Fill all cracks and voids using a flexible, waterproof elastomeric sealant or crack filler (extending from the rooftop to the base).Waterproofing Membranes: Embed reinforcing polyester membranes over larger joints and structural stress points for added durability. Phase 3: Waterproofing & Damp Protection (Base to 2m)Foundation Perimeter Excavation: Lightly expose the base of the exterior walls to ensure total coverage.Bituminous or Liquid Rubber Application: Apply a heavy-duty, rubberized bitumen or flexible liquid waterproofing membrane (like Sika or Plascon systems) around the base and up to the 2-meter mark on the ground-floor walls. This serves as an impenetrable barrier against rising damp and groundwater. Phase 4: Priming & PaintingSanding: Sand the newly repaired and waterproofed surfaces to create a smooth, even texture.Priming: Apply a high-quality alkali-resistant primer or plaster primer to bind the surface and prevent future paint peeling.Topcoats: Apply two coats of high-grade, UV-resistant exterior acrylic or textured waterproofing paint (e.g., Dulux Weatherguard or Plascon Wall & All).
