Filling around a cast iron insert and wooden surround

Postby Fourthchoicekeeper » Wed Nov 11, 2020 11:40 am

Help I’m looking to fill a gap between a recently installed cast iron fireplace insert and a wooden surround. The original wooden surround was damaged and could not be used so a new one was purchased. I think I may be able to get the gap a bit smaller by readjusting the surround a bit but there will still be a gap. I’ve done research this morning and I’ve seen several items which may do the job, fire proof expanding foam, high performance wood filler and heat resistant plaster. Not sure what the best way forward is any suggestions would be great.

Hi fourthchoicekeeper
Whatever filler you try to use it will always crack. Suggest you use a timber fillet painted white to match the surround.

Hi that’s what I ended up doing in the end, modifying the surround, just added two strips of pine on the legs at the back and you won’t be able to tell once it’s been painted. Thanks for the reply
