I have a bedroom cast iron fireplace that I have had my decorator strip years of gloss off. He has polished it with some fireplace past/polish - but the problem is this comes off when you rub against it! Have two children with SEN and am really nervous of the black stuff getting on their hands/all over the curtains/walls etc. whilst it looks lovely, is there a paint alternative I can use, and can I paint it on top of this paste/polish stuff?? Any help gratefully received!
