Well I just have.
Having cut the wall panel that will go over the window (which required lots of "offering up" and trimming of the profile) I needed to insulate around the window. I could have used my hi-tech blanket but it would have to be cut into small pieces, so instead I decided on expanding PU foam in a can... because I thought it would be quick and easy!
How wrong was I?
The instructions explained that the foam is cured by moisture so the surface should be prepared by being made clean, grease free and moisturised! And this is where the problems began. The surface is inclined gloss paint which I'd damped down with a water spray and I was trying to get a liquid to stay where it was put.... platting fog might have been easier!

The only thing that seemed to work was applying small blobs, leaving them to cure and then coming back to add blobs between the cured blobs. The whole process took nearly a full day and looks like something from a horror movie.
On the upside, following some trimming, the wall board can now finished which means that I can now start on the furniture.
