Working on a drop sheet, remove the seat and back. Use a screwdriver to loosen the screws from the frame. Tip: Treat rusty screws with rust converter to reuse when reassembling the chair.
Wear gloves, glasses and a mask suitable for sanding and painting. To paint the metal chair tips (ferrules), apply tape around the timber legs and lightly sand the ferrules with 120-grit metal abrasive paper. Wipe clean. Spray the ferrules with white paint, holding a cardboard offcut behind to avoid overspray. Apply two coats, leave to dry after each.
Remove tape and smooth over the timber frame with 240-grit abrasive paper. Wipe clean with a damp cloth.
Apply liquid beeswax over the frame using a clean cloth. Leave to dry for half an hour then buff all over in a circular motion with another clean cloth.
Position cushion covers over the seat and backrest. Cut open a cushion insert and use the stuffing to pad inside the covers. Fold the covers towards the underside of the seat and rear of the backrest, clamping with spring clamps. Staple the open edges of the covers to the underside of the seat and rear of the backrest.
Find the screw holes under the seat and at the rear of the backrest, marking them with a pen. Reassemble the chair by pushing the screws through the holes in the frame and the fabric, tightening them into the seat and backrest with a screwdriver.
