Hi
I have two radiators that have been fitted with the pipes now coming horizontally out of the wall, with involved cutting a 12" high channel into the solid block wall from floor level upwards about 2" wide.
With the pipes now in position, what should I use to fill this channel over the pipes. My plumber said use trade polyfilla, someone else said use 'bonding' and another said use a sand/cement mortar. And now the guy at the DIY store has said do not use any of these, as the heat from the pipes will crack the filled material. What should I use?
Any suggestions gratefully received.
