Fit corner strips according to their function


At the upper and lower corners of a room ceiling or skirting boards are attached. Both corner bars are similar in mounting method. They complete the transition between two perpendicular surfaces. They cover expansion joints in the floor area and serve as cable ducts. On outside corners they protect.

Different materials require different fittings

In most cases, skirting boards are made of styrofoam, skirting boards made of wood or laminate and as protective strips for outside corners made of sheet metal. Accordingly, the attachment methods differ:

  • Styrofoam is glued and painted or plastered
  • Wood or laminate is glued, nailed or clamped, rarely screwed
  • Metal sheet is applied with filler

At corners that collide with each other, miter cutting is the most elegant and practical solution. In the ideal case, the 45-degree cut forms an almost invisible joint, which disappears at the latest with the brushing. Skirting boards can be provided with irises at the transitions.

Only place the base and fasten vertically

Skirting boards that are attached to tiled floors can be fixed by means of only the vertical wall surface. They just sit on the surfaces of the tiles. An additional gluing is not recommended to get the disassembly opportunity.

If strips are nailed, a thorn should be used to bring the nail heads at least just, better recessed, in the groins. When nailing, any cable ducts that run in the profiles should be taken into account. Otherwise, incorrectly set nails prevent the cables from being pulled through or damage already laid cables.

Fill and trim

Cornices made of sheet metal consist of perforated or perforated flanks. After placement, they can be attached to multipurpose or plasterboards, in which they are included in the surface filling.

When cutting the corners, different tools are available for the various materials:

  • For Styrofoam cutter, wallpaper knife or hot wire saw
  • For wood and laminate stitch, circular or manual hacksaw
  • For miter cuts, a miter box with matching miter saw
  • For sheet metal metal scissors or hacksaw

Tips & Tricks

When attaching trim strips behind which something is "hidden", such as cables or expansion joints, you should choose a reversible fastening method. Then you can subsequently replace cables without damage or supplement and re-seal joints and clean.
