How, or with what, do I cover the expansion gap around metal posts? With 1" radiater pipes its easy using click together fittings, but with such a large circumference pipe i can't find anything that I can lay around the pipes. Any ideas??? Help!
Sealant. You just have to keep the cuts neat. You can also use the project we have on angles used in carpentry to cut beading into small sections and mitre them together to go round the pipes. See project links above
