There was a thread that I read the other day with accompanying photos, of a load of white gloss removed by steam which surprised me as it was on brick. I once tried to get gloss paint off sandstone and completely failed, that is to say it left a ghosting. I would have thought it must depend on the type of brick, soft wire cut or say smooth (or whatever type) class one engineering; but am not stating that I know about how to remove it- I am interested to hear from those that (hopefully) do though.
So I will be interested to hear how you go on with that one Ged- please post once you have tried your chosen method, and certainly I would appreciate it
