I've fitted a new rim lock to our front door and now need to fill in the hole left by the old one - I couldnt reuse this because the old lock had basically fallen to bits inside the door and made the existing hole unusable.
whats the best way to go about filling in a reasonably big hole in a timber door - I'm obviously going to be repainting it eventually.
I would make a round wooden plug to fit the hole. Glue it in with PVA and then use car body filler to make good.
Reasoning being it's mostly wood and will expand/contract with the rest of the door, and car body filler makes a bloody good tough finishing seal.
Obviously if you want to varnish a natural looking door you have to make the plug as large as possible and try matching with a proper wood filler. It has been said that PVA with fine sawdust makes a very good wood filler.
If you don't want to see it again, cover it up with something. To fill it, timber will probably be least likely to "show through" paint.
