Hi @KG1,

Welcome to the Bunnings Workshop community. 

For our wonderful members to be able to assist you, please invest some time in giving us as much information as possible about your problem. Preferably also take photos so members can see what you are working with and can provide much more specific advice about methods to tackle the project. 

We look forward to being able to help,

Jason
