Hi @Renz i personally haven’t had any issues with ours yet. All still look like new
Welcome to the Bunnings Workshop community @Bmac. It's amazing that you've joined us, and many thanks for your questions about this incredible project.
Do you have a similar project in mind, or did you like the look and were considering using these rocks in some landscaping?
We look forward to hearing all about your plans around the house and garden and would encourage you to let us know any time you need assistance or have something to share. I trust you'll find loads of inspiration within the community as our amazing community members contribute their own projects here all the time.
