Where a wall panel job looks wrong, it is rarely the panel. It is the last
20mm at every edge - the corner, the ceiling line, the floor.
Five things that decide whether those joints close cleanly.
1. Match the trim to the junction, not to the panel.
Internal corner, external corner, end cap, ceiling strip, floor line -
five different profiles doing five different jobs. Using one profile
everywhere is how you end up with a gap at the one junction it was never
shaped for.
2. Cut to the junction, not to the panel width.
Measure the opening first, then take the panel down to suit the trim's
return. A panel cut to a nominal width with the trim fitted afterwards
always leaves a shadow line where the two decide not to meet.
3. Let the trim close the joint - do not force it.
Trims are there to take up movement. Run the panel in, seat the trim, and
let it finish the joint. Forcing the panel hard against the wall to "make
it tight" is what pushes the edge back out again.
4. Order of work matters at a corner.
Set your first panel to a plumb line, fit the internal corner, then run
into it. Working outward from a corner and working toward one give you
very different gaps on the last panel.
5. Check the ends before you close up.
Look along the whole run for daylight at the edge, the ceiling line and
the floor before the last piece goes on. After that, it is a re-do.
The panel is the easy part. The edges are the trade.
