Step 4 Remove all sharp edges on the slats, then round off at the ends with 80 grit sandpaper, before applying a primer undercoat. Sand lightly between top coats.
Step 5 With the paint dry, line the slats together and flush at the ends. Now measure and mark 20mm in at either end and mark the centre. These are for the placement of the support slats.
Step 6 Mark the centre points of the support slats and drill 4.5mm holes to these marks.
Step 7 With the slats still placed out, line and fix the support slats to the holes, ensuring they're flush at the ends and to the pencil marks. Repeat Step 2 until complete.
Tip: Set the clutch on the screw gun for the screw head to sit just below the surface.
