Good afternoon all. I'm going to be using FM330 foam as an intermediate around my Upvc windows and leaning towards finishing with Compriband TP600 on the exterior edge but depending on overall cost I might use an lmn silicone.

So my question is are any Lmn silicones compatible over the FM330 or if any at all being they could react with the foam.

 

Thanks all

One of my window openings isn't square so I don't have the gap to use TP600 on it. I plan on doing exactly this for that window. 

Funny, one of my windows isn't square either. So am I safe to say the silicone won't react with the foam.

Thanks

I'd contact Illbruck. I did so recently to confirm that FM330 is still a/t when trimmed back (it is) and they were v helpful.

Thanks redbeard , why didn't I think of that.🙈

Spoke to illbruck today they were very helpful and confirmed all would be fine then cheekily recommended their own brand of silicone.
