Proper weather conditions are essential—dry, mild days are ideal. The property must be accessible, with clear space around walls or structures to be painted. Depending on the size and height, scaffolding or ladders may be required. Preparation includes cleaning surfaces, removing old paint, treating mould or algae, and repairing cracks. The right paints or coatings must be selected based on surface material (brick, render, timber, etc.), and safety precautions are necessary throughout.
