$1.09The Story
Pine quadrant moulding 15mm x 15mm is a small-section softwood trim used primarily to cover expansion gaps around laminate and solid wood flooring and to finish internal corners cleanly. Cut to 2400mm lengths from straight-grained pine, it is lightweight, easy to work with, and ready to paint or stain.
Specifications
| Property | Detail |
|---|---|
| Material | Pine softwood |
| Nominal Size | 15mm x 15mm |
| Length | 2400mm |
| Profile | Quadrant (quarter-round) |
| Finish | Planed / smooth face |
| Use Class | Internal use only |
What it is used for
- Concealing expansion gaps between wood or laminate flooring and skirting boards
- Neatening internal corners where two walls meet or where a wall meets a floor
- Finishing the joint between a worktop and a tiled or plastered upstand in kitchens
- Providing a clean edge detail on shelf returns, cabinet backs, and light joinery work
Fitting and handling
Store the moulding flat in a dry, well-ventilated space and allow it to acclimatise in the room where it will be fitted for at least 48 hours before fixing. Secure using 25mm or 30mm panel pins at roughly 400mm centres, or bond with a suitable wood adhesive where pinning is not practical. Once fixed, fill any pin holes, prime the bare timber, and finish with two coats of interior paint or a wood stain of your choice for a neat, lasting result.
FAQ
What is the difference between quadrant moulding and scotia moulding?
Quadrant moulding has a simple quarter-circle profile and sits flat against both surfaces at 90 degrees, making it the most common choice for flooring edges and internal corners. Scotia moulding has a concave, stepped profile that projects slightly further from the wall, giving a more traditional decorative appearance. Both perform the same practical function of covering gaps and finishing corners.
Can I use 15mm x 15mm quadrant to cover a flooring expansion gap?
Yes. A 15mm quadrant is one of the most widely used sizes for this purpose. The moulding should be pinned or glued to the skirting board only, not to the floor itself, so the floor can continue to expand and contract freely beneath it.
Does pine quadrant moulding need to be primed before painting?
Yes. Bare pine should be knotted on any visible resin knots, then primed with a suitable wood primer before applying a topcoat. Skipping the primer can lead to uneven paint absorption and bleed-through from resin, particularly on sap-heavy pieces.
