Hello

A few years ago I was given a pot of soft filler by an air con fitter, it was a bit like blue-tak or plasticine, maybe a bit thicker.

We used it on a few jobs to seal up ways through walls, portakabins, cold rooms etc...

It is made for this purpose as a quick, weatherproof alternative to sand & cement or foam etc... the stuff we had was dark green but I think it comes in other colours.

Does anyone out there know what this stuff was called and where I can get it, I've done a few searches on line and asked at a few trade counters but nobody knows what it is.

It's very handy for weathering cable ways through masonry etc...

Thanks
