Piddling down in Luton.....anyway, the flue to my Glowworm 24ci wall hung boiler exits the brickwall through its little hole. This hole is somewhat smaller than the previous boilers large square hole. The size difference has been `made good` with sand/cement. Problem is that the sand/cement against brickwork (outside wall) is as appealing to the eye as Dot Cotton. Any ideas on making this more prettier ?
