I am installing a victorian fireplace in a previously blocked up opening. This will be purely decorative as the flue is a mess and we don't have the time or money to sort it out. The fireplace we have bought has a slate surround with a cast iron insert. I know how to attach the insert - we've done this before - but am unsure what to do with the slate surround.
A 'how to' guide online said that to attach a slate surround you have to break off the plaster on the chimney breast and attach it to the brickwork using bonding plaster. What I want to know is if this is necessary when the fireplace will be purely decorative. Can I not just fix it to the plaster, which is sound? If anyone has done this, what adhesive did you use?
Thanks for your help
