Looking for advice on what products I’ll need to patch this chunk that someone has taken out of our wooden arch.
Hello @flightpath
Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your question about patching your wooden arch.
I suggest using Parfix 500g Ready To Use Multipurpose Filler. You can use a Pro Renovator 50mm Plastic Scraper to spread the filler in the hole. Once the patch is dry use Flexovit 100mm x 1m 240 Grit Painted Surface Sandpaper Roll on a UNi-PRO Cork Sanding Block to get a nice flat finish. Please make sure to give the patch enough time to cure.

Please keep us updated, we look forward to seeing the damage patched and repaired.
