Here Come Demould - Of The Mould

Having left it for more than long enough for the silicone to cure, I start to break off the foamboard from around the outside. It looks reassuringly solid.

Blimey, it is solid. It is also solidly stuck to the tile. I hadn't given a great deal of thought to how I might get it off; fortunately it responds to brute force.

And, to my complete surprise, it looks pretty impressive; lots of detail with not much tidying up to do. So far, so good.
