I had enough spare time, and a clear table, to do the nerve wracking bit on Bank Holiday Monday, namely pour about 1/3 of a bottle of Javis Scenic Water into the hopefully liquid-tight marsh area, and leave it to dry somewhere dead level that the cats won't get to it.
This wasn't as hard as it might have been - we have enough space in the house that I could commandeer the dining table and shut the doors, and I have a very handy iPhone app that is a very useful spirit level. It's still a bit nerve wracking, though, and I made a point of leaving it longer than the bottle recommended before yielding to any temptation to check it! The other issue is the resin water has quite considerable surface tension, so tends to leave slightly unrealistic looking edges. I found that adding a little more resin very carefully along the more prominent edges after about four hours seemed to hide this quite well.
