Thank you The Gaudy Garden for your comment. The stuff I'm using to try and repair the earn is a mastic that is intended for sticking stone and marble. You have to mix a hardener to the resin at a rate of 3 parts hardener to 100 parts resin. It goes off pretty quickly even on a cool damp day such as today. I also bound the whole lot together with some wired so that it didn't try and seperate before it was set. I slid the earn around on the board tonight and it seemed solid but I will leave it as it is for a couple of days to be on the safe side. I don't know how long it will last as only time can tell us that.
