Hi,
I am installing a victorian cast iron surround.
There is currently a gap from the previous fireplace and the surround fits neatly into the hole. However, the masonry that the surround needs to join up to is very uneven - there is over an inch difference in places - you can see a photo of how it looks at
What is the best method to fix the cast iron surround to the uneven brickwork and how should I fill the spaces in between? I have read up a little and seen various suggestions including firerope, fibreglass or lime plaster but none actually explain how to make a wall flat and fix the cast iron to it...
Any suggestion very welcome.
Thanks
GP
