GRAFO THERM spray anti condensation on tin building

[Rogerroger]

Hi everyone
I bought a load of box profile roofing sheets cheap that don't have any insulation on. Has anyone used grafo therm anti condensation spray? I'm tight so want to do it myself but is it cost effective or am I better to pay professionals to do it? I can buy a spray gun for about £50. Thanks in advance

Keen to follow this thread as we have lots of sheds that are weeping just now and it's a pain.

I had a chat with a really helpful chap from grafo therm in saxmundham. He can supply the foam and a spray gun to do my roofing sheets. He recommended doing the sheets before putting them on the building but it can be done on a finished building. I'm going to wait until the weather is warmer to dry the foam. I'll update you how it goes

Cheers. Thanks for the update.
Did he happen to mention what size of compressor you would need. Think I've only got a 50 litre one.
Although always happy for an excuse to buy bigger.

It needs to be sprayed at 100psi so i imagine it would be a lot of work for a 50ltr one. He said to search on YouTube for grafo therm and watch the videos by total container solutions, it looks really simple.
