I want to conceal some 10mm copper radiator pipes below plaster depth.
once secured to the brickwork what can I cap them with so as the heat
does not crack the plaster or discolour the wallpaper ?. I have
previously tried this without putting anything between the pipework and
the plaster which resulted in the above problems. Do I need to be aware
of any chemical reactions eg. between copper pipe and steel capping.
any help will be much appreciated,thanks
