From 2' x 8' length of MDF, rip and crosscut backing for moulding components, 1/4" wider than width of mouldings. Rip 3" MDF strips for detail below windows.
Afix mouldings to backings
Using carpenter's glue and 3/4" 18-gauge brad nails, fix backing strips to mouldings allowing 1/8" overhang on all sides. Allow glue to dry.
Finish joined lengths
Fill the routed edges with plastic wood. When dry, sand with an orbital sander and 150 grit sandpaper.
Prime all mouldings, 3" MDF detail and 1/2" cove moulding prior to cutting and installation.
Measure and layout
Measure window and lay out mouldings. For plinth and corner blocks, centre casing. For our project the plinth and corner blocks are 5/8" wider than the casing so we centred the casing to leave a reveal of 5/16".
Install trim with 2" 18-gauge brad nails and carpenter's glue. Install the 3" MDF strips and 1/2" cove moulding with 1-1/4" 18-gauge brad nails.
Fill all brad holes and seams with latex caulking then apply a final coat of paint.
