The 67x18mm Half Splayed MDF is a good middle-ground option when plain trim feels a bit basic, but you don’t want anything overly detailed. Its 67mm face gives the moulding enough width around a doorway or window, while the splayed section brings a noticeable change of angle to the profile. At 18mm thick, it also has a decent amount of depth once fitted. This size can work well for everyday interior finishing, whether you’re tackling a new room or pulling out old mouldings during a renovation. Before ordering, check the skirting it’ll meet — getting those two pieces lined up makes a big difference.
