tiling above a Window

[Time's Ran Out]

Had a full underside of a travertine window drop down onto a seating area I'd just tiled.
Tiles stuck to the plaster, but plaster couldn't take the weight of new tiling.
We all learn.
Now I usually take the head of the window off and reboard/refix - just to make sure.
Then it's 3 lengths of timber well wedged!

I have 2 small g-clamps in my bag, I just clamp 2 batons together to make them the right size, then a bit of plasterboard across tiles.

I use rapid set adhesive with an excelerent hardener goes of in about 3 mins. saves messing about

What is it then and don't say you pee in it...
