Just decorating our house, and the radiators previously had wooden shelves bonded to the top of them with some kind of sealant. Is this method ok to use, or can it cause problems with hot airflow etc.? Or should I use brackets to hook the shelves over like the ones you can purchase? If I should go for the brackets, is there anywhere that sells them on their own? I'd prefer to reuse the shelves we have, rather than buy new ones esp as one is 2metres!
