Prepare
Clean, dry, moss-free wood
Stiff-brush the shed to remove moss, lichen and greyed wood, treat with a fungicidal wash if needed, and let it dry through two days of fine weather: garden timber must be dry to the core. Scrape off flaking stain or paint, sand planed wood with 120 grit; rough-sawn timber is only brushed. Replace rotten boards.
A wooden bench or table is washed with degreaser and sanded with 180 grit; an iron piece is wire-brushed clean of rust. On bare wood, board ends and brushed metal, apply our Multi-Surface Primer in the tint matched to the colour, a dark tint under Blueprint or Forest, white under Lambeth Walk.
