Hi again Vica
Mitchell has suggested polyurethane wood glue what ever you do not use too much as polyurethane glue will foam up and is hard to clean up and has a tendency to push the matting parts, apart where PVA types of glue can be held in place with tape. (so long as all parts are clean) The best wood glue for all my work is Tite Bond III water proof glue 20min drying time to start working with, however Bunnings does not stock it unfortunately. Poly glues are strong and have good proprieties. Down fall foams up when being used, hard to clean, require clamps to hold parts under pressure while drying
From what you have shown no clamps need. just tape
I think gorilla glues has a product similar to tite bond which Bunnings does have.
The bog suggested is fine for large areas. for the small and fine holes and cracks I use Timber Mate (Australian made Australian owned) and much easier to work and quick drying time (sand back). I would suggest a visit the the timber mate web site for further info. I am currently I visiting Darwin working with Darwin Mens shed and all we are using is timber mate filler but would not use for very large holes etc. For all their projects Tite Bond III water proof is being used.
But each to their own.
All valid points @r23on! I got very used to using Builders' Bog on my door as I had a dog that would manage to escape the backyard every other day and then sit at the front door chewing at it until we got home. It got to the stage that there was more bog in the door than actual timber. You're correct that a timber putty would likely be more suitable for smaller holes, and the polyurethane glue should be used sparingly.
Many thanks for sharing your knowledge and experience.
This product is what I was talking about great for all small holes creaks. for really fine holes I mix a small amount with water to make a very wet past and paint it on. it gets in to hair line cracks. I use mainly the natural colour as it takes on most stains matching the the timber stained. hope all goes well for you.
@MitchellMc Thank you! My wish is installing a new handle. About the door itself ,the holes is near but not on the spot I will drill for handle.(image1) . But door frame is different It may be very very near the drill spot. And one surface is made by concrete.(imag2). How to fill it so that I can install a handle? Certainly bog is best because it can be drilled. I think detailed advises is very best. Also which handle is very important .
As to which plastic wood filler to use I have no preference as they all seem to do the same task. the issue I had was finding the correct mix of hardener to filler ratio to shape or mould the shape before the hardener sets the filler. The other issue was the workability of the plastic wood after setting. Too much hardener sanding hard work not enough hardener the sanding material clogged quickly.
End result I try to fit a new section of suitable timber in and fill small gaps with wood filler/putty. Down fall longer repair time upside better finish. Horses for courses. I think for memory I mostly used the plastic wood you suggested.
But then I tend to take the long path.
