Oak quadrant moulding 18mm x 18mm x 2400mm is a solid hardwood trim used to cover expansion gaps along wooden flooring edges and to finish internal corners neatly. Supplied in a 2.4 metre length, it suits both floor-level and joinery applications throughout the home.
Specifications
| Property | Detail |
|---|---|
| Material | Solid oak (hardwood) |
| Profile | Quadrant (quarter-round) |
| Nominal Size | 18mm x 18mm |
| Length | 2400mm (2.4m) |
| Finish | Unfinished / bare wood |
| Use Class | Internal use only |
What it's used for
- Concealing expansion gaps between solid or engineered hardwood flooring and skirting boards
- Neatening internal wall-to-floor junctions where a tight fit is not possible
- Finishing worktop-to-wall joints in kitchens and utility rooms
- Covering gaps at skirting board returns and internal corner junctions
Fitting and handling
Before fixing, allow the moulding to acclimatise in the room for at least 48 hours, particularly in heated or humid environments, to reduce the risk of movement after installation. Fix using lost-head pins or a suitable construction adhesive, ensuring you do not nail through the moulding into the floor itself, as this would restrict the natural expansion of the board beneath. Once fitted, the bare oak surface can be sealed, oiled, stained or painted to match your existing floor or joinery finish.
FAQ
What is the difference between an 18mm oak quadrant and a larger 21mm or 25mm version?
The 18mm x 18mm size covers a gap of up to roughly 15mm and suits standard domestic flooring installations where expansion gaps are modest. Larger quadrant sizes are used where wider gaps need to be concealed or where a more prominent visual detail is preferred.
Can I paint or stain this oak quadrant moulding?
Yes. The moulding is supplied unfinished, so it can be oiled, varnished, stained or painted once fitted. Lightly sanding with 120-grit paper before applying any finish will help the coating adhere evenly across the grain.
Should I fix oak quadrant moulding to the skirting board or to the floor?
Always fix to the skirting board or the wall, never to the floor. The moulding's purpose is to sit against the floor while remaining attached to the fixed structure above, allowing the flooring to expand and contract freely beneath it without buckling.
