How to attach moulding to the ceiling?

I want to create some visual interest on my ceilings and help divide the rooms in an open plan so I can different ceiling paint colours.

Looking at a moulding like thr below

Would liquid nails be enough to hold this in place? I won't have any joists to nail into but could send some nails at different angles into the drywall to assist in holding at least until the glue dries?

Hello @Snakeytail

Your proposed plan of using liquid nails in combination with small fixing nails to keep the moulding in place is a sound idea. I suggest using Selleys 420g Liquid Nails Construction Adhesive Fast Grab - 3 Pack. My best advice is to drill pilot holes for the nails for ease of installation and to prevent accidental damage to the ceiling boards while driving the nails in.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let us know.

Hi @Snakeytail

@EricL has hit the nail on the head excuse the pun. You will also need some wide painters tape to hold the timber trim in place until the liquid nails sets.

Good Afternoon @Snakeytail

I would even go as far to use a stud finder to see if you can locate the trusses above so you can nail the timber to the ceiling as well.

My ceiling isnt perfectly flat (depends on the age and how the ceiling is going) So maybe tape some timber up first to see how it looks befor liquid nailing it to the plaster. The waves may sho up more pronounced with the trim and painting in place.

With the liquid nail, wipe the excess away as soon as you have put the timber trim up. It will save you a LOT of work later.

Unfortunately, my ceiling gyprock is hung using battens, so there is a gap between the board and the joist above. I would have to screw into the batten itself, which is a hit harder to hide than a nail hole.

If I use painters tape to hold in place while it dries, would I even need nails since it's only going into the gyprock?

Potentially not @Snakeytail, as the glue alone might be enough. However, bear in mind that you are not gluing to the Gyprock, you're adhering to the paint which is attached to the Gyprock. So the weight of the timber is essentially being held up by paint. If the paint is not well bound to the Gyprock, then it could delaminate. Mechanical fixings through at least the plaster will assist in holding it in place. Can you use thin nails to fix through the battens?
