Could anybody tell me if it is OK to use normal cement (Castle Cement) in the mortar mix for rebuilding top 5 rows of the chimney and should it be 3:1 mix?
I have read on another website that it has to be Portland cement that contained sulphate so that it didn't react with the gases from the gas fire.
Also, is it common practice to line the inside of the chimney with mortar?
Thanks
