Flexible Arch Trim Wall Molding Kit

Flexible Arch Trim Wall Molding Kit, Pre-Cut MDF Decorative Wall Panels. A flexible profile lets this Paintable MDF Flexible Arch Trim follow a curve without splitting, so arches stay smooth from end to end. Choose a medium 27.6 inch or large 37.8 inch width, one to three panels. The trim ships as Pre-Cut Wall Panels, ready to fix, fill and paint for an arched feature wall.

This arched wall molding kit puts a single curve into a room built entirely out of straight lines, which is why it reads as architecture rather than decoration. The arch is cut to its radius in the workshop, so you are not steam-bending trim on a ladder.

Paint the wall and the molding in one color and the arch reads as a recessed niche. Paint the molding alone and it reads as a frame. Both work; the first is the look most customers go for.

What is in the kit

• Pre-cut MDF arch sections plus the straight legs
• Factory-cut joints so the curve meets the legs cleanly
• Molding Size: Medium 70 cm or Large 96 cm
• Panel: 1 Panel / 2 panel / 3 Panel
• Raw, sanded MDF: prime the cut edges before your top coat
• Numbered pieces and a layout reference

How it goes up

1. Mark the centre line and the spring point where the curve starts.
2. Dry-fit the arch section against the legs before any adhesive goes on.
3. Run construction adhesive along the back and press home, taping until cured.
4. Fill the joints, caulk the edges, prime the cut MDF and paint.

Sizing it to your wall

Measure the wall width and the height from the baseboard to the ceiling, then decide where the top of the arch should sit. Behind a bed, keep a clear margin between the arch and the ceiling. In a hallway, two-thirds of the wall height is a comfortable proportion. Our free wall molding calculator works out even spacing when you are running more than one panel.

Where it works

Headboard walls, hallway end walls, alcoves either side of a fireplace, entryways and home offices. Any flat, dry interior wall. Not for outdoor use or walls with an ongoing damp problem.
