Part of my ceiling cornice is coming off and not sure of the best way to fix this.
Is this a liquid nails job or another product.
Also, how to you keep pressure on it once glued?
Many Thanks
Hi @Justin_W_L,
Welcome to the Bunnings Workshop community, it is wonderful to have you with us.
I'd suggest you start by removing that short length of cornice altogether, being careful not to damage it in the process as you will be reusing it. This can be done by cutting along the mitres and the top and bottom lip of the cornice with a utility knife, then gently prying it off using something like a chisel. Make sure you wear gloves and long protective clothing to help reduce the risk of lacerations or injury.
Once the piece has been removed, tidy up by cutting away any jagged plaster from the mitres and scraping off any remaining cornice cement from the ceiling and wall.
You'll then take some cornice cement, mix it as per the instructions, and apply it liberally to all four edges of the cornice using a before pressing it into place. Use a plaster knife to apply the cornice cement and scrape away any excess that pushes out when the cornice is pressed into place.
To hold it in place while the cornice cement dries, you can prop it with a long piece of timber, or something like this https://www.bunnings.com.au/gorilla-155-290cm-piher-adjustable-multi-prop_p0188653 , or drive a temporary nail or screw into the wall underneath the bottom edge.
The cornice cement will take around 2 hours to set, at which point you can remove the temporary prop, touch up any holes or inaccuracy with some fresh cornice cement, allow it to dry, then sand everything and paint.
Let me know what you think and if you have further questions, please let me know so I can assist further.
