yea i used SLC, but you still see the cables on the surface of the SLC, cant have put enough on ?? so i don't want to damage the UFH with a metal trowel?? am i being a fanny? :yes:
PlasPlugs make one. I used one with WarmUp loose wire and BAL Fast Flex and it was fine - it would definitely have lasted more than one job if I had bothered to clean it up . Found it in a local tile shop and it only cost a few quid.
You should get one for about 2.99, if you take a file and file down the edges of the u shaped notch it doesnt catch the matting as much, make sure all your products are flexable by the way
