Covering/filling over expanding foam

[kjacko]

Hi all,
so, had new windows put in and the fitters filled the gaps with expanding foam.
Question is, how do i now fill the remainder and smooth off?

Thanks for any advice.

Others may give other suggestions but I would hack off any foam extending beyond the thickness of the plasterboard and then just fill it polyfiller or easi-fill. It might crack if the window moves/settled but it proberbly wont. Decorators calk to finish if you want but I wouldnt.

If it does crack in one or two areas on one of the windows I would then just hack it out and re fill it but leave a 2mm gap to the window and then calk that.

Get some slightly thined down filler on you fingar and wet the edge of the PB is you want. Tbh though, mainly, I would just get some filler in there, slap some paint on, and revisit it if it moves, which it proberbly wont.

The beading isn't properly clicked into place either.

The gap is about 2inch wide at its max.
Will easyfill or multifinish really stick to it without any extra work?
I'd caulk the edges like i'd caulk any edges when preppring for decoration/painting. I take it you weren't suggesting using caulk as a partial filler?

Lol....oh yeah, didn't notice that, thanks bud.

a serrated knife will easily cut it off. Decorators caulk will finish it. It can be painted but the surface will not be smooth unless you use filler or plaster (which will stick to the cut surface)

Not suggesting using calke as a filler, just stopping the filler a mill or two short to allow some flex rather bridge onto the window with it.

Two inches is asking a fair bit of the filler, but assuming the window doesnt move it has the foam to support it and is so much quicker than any other option I can see I would do that first as I will probebly not cause any problems and if it does you have lost little.
