How can I repair damaged MDF door frame?

Luke5

My dog got shut in the bathroom area accidentally for some time and tried to eat his way out. Looking for suggestions on how to tackle this. I was thinking of sanding/cutting the swollen wood off (what is it by the way, mdf, particles board?) and using wood filler to achieve shape and sand/adjust shape as necessary.

Welcome to the Bunnings Workshop community @Luke5. It's brilliant to have you join us, and many thanks for your question about repairing architrave.

The material is MDF (medium-density fibreboard), which can swell and crumble when exposed to moisture. You can repair the damage by removing the swollen section and reshaping it using a product like Builders Bog. This filler can be moulded and sanded to recreate the original shape.

However, keep in mind that re-creating a moulding can be tricky. Depending on your skill level, replacing the entire length of moulding might be a better option. It would ensure a clean and seamless finish, especially since MDF doesn’t always take repairs well.

Please let me know if you have any questions.
