Hi there, have looked through the posts but have found no good answers for my current problem!
Following a complete renovation of my cottage, I am fitting a wood burning stove into the old, very sooty, fire place opening. My understanding is that sooty acidic deposits on brick eventually travel through most materials - unibond, render, or even tile grout. My current thinking is to unibond, then lime render (to create a nice level finish) then tile, using a dark grout- so that if anything does travel through it wont look too bad! Other option is to wirebrush as much surface deposits off as possible, re-point and leave bare-bricks on show. Anybody got experience with using heat-proof board - guess I could bond that on and then tile over?
Any thoughts out there?
Thanks,
Tom
