The plaster around the radiator pipe in my bedroom is crumbling. There is also a slightly annoying clicking sound at times, which I guess is the materials moving as the temperature changes. How would you cover up the hole? With something rigid like expansion foam or plaster, or something flexible like an acrylic grout?My idea was to fill the hole with one of the above and then finish it off with a layer of plaster. But I guess plaster on top of something flexible is just going to cracks again...
Could you get a slightly larger pipe around that pipe then fill the wall with plaster and the gap between rad pipe and newly added pipe with flexible filler. If you found a flexible enough plastic pipe and cut a slot in it you might get it over the rad pipe.
