Hi @Muhamad,

Thank you for your question about installing timber mouldings and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

The best method for attaching timber mouldings to walls is to use both brad nails and Liquid Nails. 

Brad nails are most effective when they are shot into a timber stud, but they are not always available where you need them. Using both nails and an adhesive will ensure that it is held strong even when the nails can't be fired into a stud.

A tip you can use where a stud isn't available is to fire two nails close to each other at opposing angles. This will make it much more difficult for the timber to pull away from the wall. 

If the timber is not primed, I would suggest using Dulux 1Step Prep Primer, Sealer & Undercoat 1L.

You can certainly use the same paint as the wall for the timber, no issues there at all.

To fill the nail holes, use Spakfilla Rapid Gap Filler and for the gaps between the timber and the wall, use No More Gaps.
