Welcome to the Bunnings Workshop community. Thank you so much for joining us and sharing your question about how to protect your Mimosa park bench.
Before I give any recommendations, would it be possible for you to post a photo of your Mimosa Park Bench? This will give our members an idea of its current condition. It will then allow us to make a comprehensive recommendation on how to protect it. One of the best ways to protect wood is to paint it. However, there are several types of paint from clear coats to stain and varnish. We look forward to seeing the photos.
