Miter corner strips at the right angle

The most practical and beautiful way to connect corner strips over the corner is a beveled cut in 45-degree angle. The ends of the strips can easily be mitred for both external and internal corners. In most cases, customizing a cutting routine is preferable to even out the masonry.

Base and ceiling strips

Baseboards usually run around a floor and are joined together at the corners. The same principle is used when attaching trim to the ceiling. An ideal auxiliary tool is the miter box, which is accompanied by a suitable miter saw.

Before attaching cornices, a coarse cut is helpful. The length of the bar must always be kept at least the length of the outer miter edge. It is sawn inward at a 45-degree angle with rejuvenation.

Outer and inner corners

Normal room corners can be called inner corners. The miter cuts on the two ends of the strips "make" the place to meet the two end edges with triangular shaped bevels. The strip ends form a right angle. The longer side is on the corner inside and the shorter side facing the room.

In outer corners such as, for example, bay windows, chimneys, wall projections, pillars and square pillars, the strip course "surrounds" the masonry. The miter cut must be mounted in the opposite direction. The longer side to the outside, the shorter side to the inside.

Mount and adjust

Almost no masonry forms exact right angles at the corners. It is most advantageous if the individual sections of the corner strips are each performed "on the object". The fitting can be supported by the following corrective measures:

  • Regrinding the sawing and cutting surfaces
  • Fill the oblique joint with glue or modeling paste
  • Placing a joint panel

Structure and shape of the miter box

The miter box is a U-shaped wooden frame with saw guide notches on both sides. They are aligned at a 45-degree angle, into which the saw blade is inserted. The trim strip to be cut is placed on the bottom of the "U". After inserting the saw blade into both guide notches, a precise cut is made at right angles.

Tips & Tricks

Most strips have asymmetrical profile shapes. By sawing and cutting "on the spot", you also avoid confusing the cutting direction.
