Hi all
I need some advice for plastering around a hole in the wall fire. The plaster needs to have a heat resistance of 70 degrees so ordinary plaster won't do. I've been looking around this site and the web and have seen the Vitcas heat resistant screed and plaster. However this plaster can only be used around the fire and as the whole chimney breast would need skimming this won't do either as we want a nice smooth finish. I have read about using a 5:1:1 sand, cement, lime render then having a lime finish using lime putty mixed with silver sand at a ratio of 1 sand to 1.5 lime putty. Has anyone any experience of using this? and would it be heat resistant enough as I wouldn't want it cracking or falling off? Also can you use normal emulsion on lime plaster?
Thanks
