Water feature update – it seems to be working, and my trick of filling the inner section certainly worked as I was able to bale it out, reducing the weight and making it flexible enough to lift out. I am leaving it in the outer for longer, as the rubber buckets will slow the curing process, though removing the inner will help it speed up a bit now.

Pleased with the finish so far, it’s lovely and smooth, taking its surface from the smooth rubber. And I’ve discovered homebase do an even bigger size of bucket……..
