I want to install a pine shelf over a radiator. What finish would provide the best protection against heat, or is that not necessary providing I leave a gap of saying 15cm? I have some polyurethane left over from a previous job, should I use that?

  • The radiator cannot become hot enough to cause combustion so it doesn't matter.

  • No worries from the heat regarding the finish. The gap you propose is more than adequate. Finish however you see fit.
