Default Repairing fibreboard backs.

Fibreboard or card backs which are broken or bent can often be repaired using PVA bonding/wood adhesive diluted with an equal volume of water. Lay the board on a flat workbench on top of a piece of plastic cut from a bin liner or supermarket bag. Re-align any of the broken slats and coat the uppermost side of the board with the diluted adhesive using a paint brush. Clamp it flat to the bench using a strip of wood with a piece of plastic underneath to prevent sticking. Any broken slats can also be clamped in a similar way.

Leave a couple of hours to partially dry and repeat the process on the other side of the board. Allow the board to then dry completely and coat both sides again with diluted adhesive. It should not be necessary to clamp again during this stage. One advantage of this type of adhesive is that it dries transparent, allowing any printing on the back of the board still to be seen. It also remains relatively flexible while giving additional strength to fragile boards.

Easier than trying to make a new one!
