STEP 1 Before removing doors from tracks, measure clearance between doors when opening and closing. If total thickness of plywood plus moulding specified is too thick, choose a thinner moulding to suit your measurements. Carefully remove doors from track, 1 at a time, taking note of which door went where. Removal of doors typically involves holding 1 door on its long sides, lifting it up into top rail and angling bottom of door towards you, removing it from track. Lay door flat in a safe work spot. Repeat for all doors.
STEP 2 To ensure mirrored face of each door is free of oils or cleaning products, wash each with a solution of water mild detergent, washing frames of each door, too. Let dry.
STEP 3 Measure mirrored face of each door and transfer measurements to plywood. Measurements may vary per door, so measure and mark up each individually. Cut ply to size using a power saw along a clamped straightedge. Lightly sand all surfaces using sandpaper wrapped around sanding block. Wipe away dust.
STEP 4 Decide on size of rectangle panels expressed on face of each door with mitre joined pine moulding. Ours have an external measurement of 840 x 1600mm (top rectangles) and 840 x 500mm (bottom rectangles). Using handsaw and mitre box, cut moulding with 45º corners for mitre joins to suit your measurements. Sand the cut edges.
Step 5 Measure and use pencil and ruler to mark up face of ply sheets with centred rectangles to indicate the locations of moulding.
Step 6 Working 1 cut length at a time, apply Selleys Liquid Nails to back of moulding and fix each length in position on ply, keeping corners square.
Step 7 Use strips of tape to hold moulding. Let dry.
STEP 8 Pour acyrlic primer and sealer into paint tray and use brush and mini-roller to paint front face and edges of all panels. Wash painting tools and let panels dry.
STEP 9 Use brush and miniroller to apply 2–3 coats of paint colour of choice to front face and edges of all panels. Let dry after each coat.
Step 10 Following product instructions, apply Selleys Liquid Nails to face of 1 mirrored door and fit corresponding panel on top. Apply weight (such as a few stacks of books placed on clean rags to prevent scuffing) across face of panel to ensure a good bond. Repeat for each mirrored door. Leave to dry.
STEP 11 While doors are out of tracks, use a vacuum to remove debris from tracks. Insert doors into tracks using the reverse procedure to their removal, taking care to return doors to their correct locations. Beginning with the door you removed last, hold 1 door on long sides, lift it up into the top track, push the bottom in towards the track and lower door into bottom track. Repeat for remaining door/s.
