Oak Scotia Moulding 18mm x 18mm x 2400mm

Oak scotia moulding 18mm x 18mm x 2400mm is a concave hardwood trim used to cover internal corner joins between wood flooring and skirting boards. Cut from solid oak, this 2.4-metre length delivers a clean, consistent finish in flooring and joinery applications.

Specifications

What it's used for

• Concealing the expansion gap between solid or engineered oak flooring and skirting boards
• Finishing internal corners in fitted furniture, cabinets and alcove joinery
• Covering neat joins between wall panelling and floor level trim
• Providing a tidy border detail in staircase risers and step nosing assemblies

Fitting and handling

Before installation, allow the moulding to acclimatise in the room for at least 48 hours so the timber adjusts to the ambient temperature and humidity, reducing any risk of movement after fixing. Fix using oval lost-head pins, a brad nailer, or a suitable wood adhesive - pin fixing into the skirting rather than the floor allows the floor to expand and contract freely beneath. Once fixed, fill any pin holes with a matching oak wood filler, then finish with your chosen stain, oil or lacquer to match your existing floor or trim.

FAQ

What is the difference between oak scotia moulding and oak quadrant moulding?

Scotia has a concave (hollow) profile, which creates a slightly deeper shadow line and tends to bridge the corner gap more generously than a quadrant. Quadrant moulding has a convex quarter-circle profile. Both serve the same purpose of covering the expansion gap at floor level, so the choice is largely aesthetic.

Can I use this oak scotia moulding with engineered wood flooring?

Yes. An 18mm x 18mm scotia is a common choice alongside both solid and engineered oak floors. Because it is fixed to the skirting board rather than the floor surface, the floor beneath remains free to move, which is essential with floating engineered installations.

Does this moulding come pre-finished or will I need to stain it?

It is supplied unfinished, which gives you full control over the final colour. You can apply an oil, hard-wax oil, lacquer or water-based stain to match your existing floor. Lightly sand to 120 grit before finishing for best results.
