Reinforce a normal cabinet back wall

Often it is in a cabinet back wall in a standard cabinet is not much more than a reinforced cardboard. The few millimeters thick press plates tend to buckling and breaking. They can be reinforced with support structures, but in many cases an exchange is the better decision.

Unsupported rear walls

A cabinet placed in a conventional manner against a wall works well with a normal cabinet back wall. By leaning against the wall, the back wall is supported. If, however, a slightly larger distance exists, for example, through baseboards, the back wall is at the mercy of its own stability.

The same applies to a cabinet back wall as a room divider. Normal back walls are difficult or impossible to paint or paper. If the back of the cabinet is not adequately fastened, it can quickly come off or even break when it is hit with objects or clothing.

Secure against bulging

In many cases, an older cabinet rear wall bulges out. In this way it loses its supporting function for the entire cabinet and, in extreme cases, can completely slip out of its insertion profiles. Theoretically, it is possible to stabilize the rear wall of the cabinet by nailing it to the inlays and shelves in the cabinet. Then, however, the floors can not be moved or turned over.

The wood or cardboard-like material of a cabinet back wall can be well reinforced with cross-guided wooden strips. The following attachment patterns are possible as arrangements:

  • In cross shape with comb connection
  • Vertical parallel bars
  • Horizontal parallel cross bars
  • At the corners diagonally attached strips with miter ends
  • As a circumferential frame

It is recommended to apply the wooden strips to the cabinet back wall. On the sides, the ends of the strips protrude beyond the back wall edges. So they can be nailed or bolted to the rear cabinet frame. Under no circumstances should the rear wall reinforcement be glued to cabinet parts. The rear wall should be removable as a continuous component including the stabilizing additional construction.

A sturdier reinforcement can be constructed by attaching the strip ends flush with the cabinet sidewalls with metal straps or brackets.

Tips & Tricks

If your profile grooves in the enclosure walls allow or expand, consider buying and installing a new and more stable back wall. In hardware stores, you can purchase sawn boards, for example made of plywood.
