Trim defines the perimeters of doors, windows and archways. Since these mouldings are highly visible, they must integrate well with the architectural style of the room. Trim is used primarily to transition the space between the interior wall cladding, often drywall, and the door or window frame.

Before Assembly

This project explains how to install trim with 45° angles. The installation of trim with rosettes in the corners requires a simpler 90° cut.

Before you start, allow the mouldings to acclimatize for 24 to 48 hours in the room where they will be installed.

You can paint or stain your mouldings in advance. You’ll simply need to touch them up a bit after, and cover the nail heads you’ve concealed with wood filler. This actually simplifies the job, because you won’t need to do any masking.

Install mouldings in the same grain pattern all the way around the room.

Use a good-quality finishing blade with a minimum of 40 teeth, though 80 teeth is preferable since the more teeth a blade has, the cleaner the cut.

Pre-drill your nail holes so that mouldings do not split. Use a drill bit of a smaller size than the nails.
