Getting Started
So, begin with filling up the hollow space behind the damaged area with insulating foam sealant to allow filler material to be applied (do it by using an epoxy filler to fill the damaged area). Create a silicone mold of the door’s finished surface texture.
Step 1 – Cut Away Loose Splinters or Fragments
There are many loose splinters or fragments around the edges of the crack on the door, depending on how much the door is affected. Instead of trying to repair them, use a utility knife to cut off all bits of broken wood until you are left with a clear hole.
Step 2 – Fill Up The hole with Newspaper (or Paper Towel)
While the paper towels will not reinforce or fix the panel, they are an easy and affordable way to keep the insulation foam in place while it dries. Bunch up a few paper towels and cram them around the bottom or side of the hole that you want to repair.
Step 3 – Squeeze in The Expanding Foam Insulation Into The Hole
With a long nozzle on top, the expanding insulation foam comes in a spray tank. Aim in the hole or smash the nozzle in your door and start spraying. The foam must expand to fill the space inside the crack, with any excess spreading through the door's face outside the opening.
Step 4 – Leave the Insulation Foam to Dry Overnight
Once the insulation material has filled in the gap or crack, it must dry through it all the way before it can be cut or sanded.

Step 6 – Apply a Layer of Auto-body Fill Foam for A Stronger Repair
