Domakihub How to Fit Laminate Beading for a Clean, Gap-Free Finish
Cut and nail scotia beading in an afternoon and hide every expansion gap around your laminate floor.
Reviewed by Domakihub home & decor pros · 2026-06-23 · 5 min read
Laminate flooring must be laid with an expansion gap around the perimeter — typically 8-12 mm — and beading (also called scotia or quarter-round) is what covers that gap neatly against the skirting board. The video above by Flooring Mountain shows the complete cut-and-fix process in clear detail; the steps below translate that technique into a checklist suited to homes, holiday rentals, and hotel rooms across Greece where tiled or concrete subfloors are the norm. No structural work or building permit is required, making this a genuine weekend DIY job.
What is Laminate Beading and Why Does it Matter?
Scotia beading is a concave-profile strip, usually 18×18 mm or 15×15 mm, sold in 2.4 m lengths in wood, MDF, or PVC. It sits in the corner between the top of the laminate board and the face of the skirting board, hiding the expansion gap without pressing down on the floor. Because it is fixed only to the skirting — never to the laminate — the floor remains free to expand and contract with seasonal humidity changes, which are significant in Greek coastal climates.
Pressing beading directly onto the laminate is the single most common DIY mistake. If the strip is glued or nailed through the floor, it restrains movement, and boards will buckle within one summer.
Tools and Materials You Will Need
Gather before you start: a mitre box or compound mitre saw, a tape measure and pencil, a nail gun or hammer and lost-head panel pins (38-40 mm), wood glue or construction adhesive for the skirting faces, a coping saw for tight inside corners, and matching colour filler or caulk for any small gaps. Buy 10-15 % more beading than your perimeter measurement to allow for mitre cuts and offcuts. In Greece, PVC beading is worth considering in kitchens, bathrooms, or any room that sees regular mopping — it will not swell.
How to Fit Laminate Beading: Step by Step
- 1
Measure the room and plan your cuts
Walk the entire perimeter and note the total linear metres, then add 15 % for waste. Sketch each wall and mark which corners are internal (90° inward) and which are external (90° outward). Internal corners are best dealt with using a simple butt-and-cope joint rather than two mitres, which rarely meet cleanly on uneven plaster walls.
- 2
Cut mitres and cope for inside corners
Set your mitre saw to 45° and cut the first length to run into an internal corner with a square end. Cut the adjoining piece at 45°, then use a coping saw to follow the profile of that mitre cut, removing the waste so the coped end sits flush over the face of the first piece. For external corners — a doorway threshold or a projecting chimney breast — cut both pieces at 45° outward so the points meet neatly.
- 3
Dry-fit each length before fixing
Hold each cut length in position along the skirting and check the mitre joints close without a gap. If a wall is bowed, the beading may need a slight back-cut with a block plane or coarse sandpaper on the mitre faces. Never force-fit; the thin profile will split. Confirm that the bottom edge of the beading rests on top of the laminate but is not pressing into it — there should be just enough clearance for a credit card.
- 4
Fix to the skirting board only
Apply a bead of wood glue or construction adhesive to the back face of the beading (the side that presses against the skirting). Press the piece firmly into the corner and nail through the top edge into the skirting at 40-50 cm intervals using 38 mm panel pins. Punch the pin heads just below the surface with a nail set. Do not use adhesive on the underside or drive any nail through the laminate surface below — the floor must remain free.
- 5
Fill, sand, and colour-match
Once the adhesive has cured (typically 1-2 hours), fill any pin holes and small mitre gaps with matching colour filler or a fine bead of paintable caulk. Wipe excess caulk with a damp cloth before it skins. When dry, sand lightly with 180-grit paper, apply one coat of matching paint or wood stain if needed, and remove any floor protection tape. Step back and check all joints from standing height — small gaps read less harshly than you expect from close up.

FAQ
- Can I use adhesive instead of nails to fix the beading?
- Yes, but use adhesive on the skirting face only, never on the floor. Construction adhesive like No More Nails or a standard grab adhesive works well on MDF and plaster skirting. The advantage is no pin holes to fill; the disadvantage is that removal later (for floor repairs or replacement) requires a little more effort with a pry bar.
- What if there is no skirting board — just a tiled wall going straight to the floor?
- In Greek apartments with tiled or rendered walls and no timber skirting, fix the beading directly to the wall using grab adhesive rated for ceramic or plaster. Alternatively, use a T-bar or threshold profile at doorways and a matching PVC cove bead along tiled walls — these come with pre-drilled fixing flanges that take small masonry screws. Never glue to the laminate itself.
- Do I need a professional for this job?
- Fitting beading is a straightforward DIY task that requires no licence or permit. A professional flooring fitter is worth calling if you have very complex room shapes with multiple external corners, if the existing skirting boards need replacing beforehand, or if the floor itself was laid incorrectly (boards too tight to the wall with no expansion gap), since that underlying problem must be fixed first.
