can u tile onto lining paper?

Hi Andy, DON'T touch rads, you are walking into trouble. See the insurance thread and you'll see I pay 5 times more than the regular tilers just to cover myself for the plumbing side. One woman paid me over 70 quid last year because her husband kept trying to take rads off himself

Spoke to a heating engineer, a mate of mine some rad valves are so old that once your've undone the nut (wivers come to mind) then try to tighten they won't seal and a leak will follow.
