Cracked particleboard can be hard to fix, and sometimes, trying to fix it can make it break. But it is not impossible to fix the crack when the board is handled correctly. You need to access the condition of your board, look for all the cracks, and determine whether it has a coating. For the project, you will need: epoxy glue, another piece of particle board, clamps, and sandpaper or melamine coating. If the crack is small, you will only need to apply glue between the pieces and let it dry. If there's a large crack that leaves a space between the pieces, attach another board and glue them together. Ensure you clam them together for them to dry and blend in. This method will leave a rough finish, which you can correct by sanding or applying a melamine coat.
