Hi Guys I am wondering weather anybody would be able to give me some advice. I have recently bought my first house, a 100 year old terrace and removed the rear chimney breast that was on an outside wall. When i removed the breast the wall behind it was quite crumbly and very sooty and dusty. The brick work has obviously been baked over the last hundred years and so is quite poor and uneven. I am just wondering that if any of you guys where faced with job what process u would use? Any advice is welcome, many thanks...
