It can be repaired with instant adhesive powder. Dry or blow dry the bottom of the wooden door first, and then remove the badly rotted place first.

Then, prepare 1 instant powder for small bags, 1 wall shovel, 1 pot and clear water. When in use, mix it bit by bit. Be careful not to pour it all into the water, because the instant powder will solidify quickly when it meets water.

Therefore, it should be repaired quickly, and finally it can be leveled with a wall shovel.

In addition, newspapers and glass glue can also be used to repair.
