The Story
Pine scotia moulding 18mm x 18mm is a concave-profile softwood trim used to cover internal corner joins, most commonly along the base of skirting boards, at floor-to-wall junctions, and around wooden flooring installations. Each length measures 2400mm, supplied by Nottage Timber Merchants.
Specifications
| Material | Pine (softwood) |
|---|---|
| Nominal Size | 18mm x 18mm |
| Length(s) | 2400mm |
| Profile | Scotia (concave quarter-round) |
| Finish | Unfinished (ready to paint or stain) |
| Use Class | Internal use only |
What it's used for
- Covering the expansion gap between laminate or solid wood flooring and skirting boards
- Neatening internal corner joins where two surfaces meet at 90 degrees
- Finishing the junction between floor tiles and timber skirting in kitchens or hallways
- General interior joinery trim work on staircases, built-in furniture, and fitted units
Fitting and handling
Before fixing, allow the moulding to acclimatise in the room for at least 24 to 48 hours, particularly where underfloor heating is present, to minimise movement after installation. Fix with panel pins or a suitable grab adhesive, keeping fixings clear of the floor surface so the flooring can expand and contract freely beneath. Once fitted, fill any small pin holes, lightly sand, and apply your chosen paint or stain to match the surrounding joinery.
FAQ
What is the difference between scotia moulding and quadrant moulding?
Scotia has a concave (inward-curving) profile, which creates a shadow line and a more traditional look. Quadrant, or quad beading, has a convex (outward-curving) profile. Both cover the same expansion gap at floor level, so the choice comes down to the style of your existing skirting and joinery.
Can I use 18mm x 18mm pine scotia moulding with laminate flooring?
Yes. This size is one of the most widely used for laminate and engineered wood floors. Fix it to the skirting board only, not to the floor itself, so the floating floor beneath can move freely with changes in temperature and humidity.
Does pine scotia moulding need treating before use indoors?
No preservative treatment is required for internal use. The moulding is supplied unfinished, so you can paint it to match your skirting boards or apply a clear varnish or wax if you prefer a natural wood appearance.
