Thank you for sharing that question about patching your Colorbond fence.
You can use small nuts and bolts spray painted in the same colour as the Colorbond to make it blend in with the fence. You could use sticky dots of the same colour as the fence. Other forms of repair will require you to use putty and sanding. However, that form of repair will make it more noticeable.
If you need more information, please let us know.
Thank you - Just used your instructions and links to do exactly the same thing!
@MitchellMcany tips for attaching the capping? (https://www.bunnings.com.au/lattice-makers-900-x-80mm-black-bamboo-screen-capping_p3041183)
Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your bamboo fence project.
My colleague @MitchellMc is currently on a much-deserved parental leave. It's great that the instructions and guides helped you to put up your own fence. To put the capping on I recommend drilling into the corner of the bamboo cap and the top of the fence. Once you have the fence cap in the position you want it in you can use Whites 1.25mm x 30m Galvanised Tie Wire.
I suggest threading the wire through the cap and into the hole you made on the fence. Once threaded you simply twist the wire to hold the cap in place. I recommend not to over twist the wire so that you can hide it under the bamboo cap.
If you need more advice or information, please let us know.
