Condensation in my shed

[caretaker]

I have a metal shed 10x8 feet with double sliding doors and a small window that will open.
My problem is I get this time of year a lot of condensation off the inside from the roof that drip down on my tools and machinery, is there a cheep way to avoid this.

The short answer is no. The longer answer is you need to insulate the walls and roof and install a vapour barier. This probably means installing an inner wall and ceiling which will mean less space.

You can spray with polyurethane foam, I would not say it was cheap though.

I am considering doing the roof of my shed with this

But at 130 m2 It's going to cost a pretty penny. Would like to know if anyone has any experience with it.?

I used the two part foam on a concrete panel shed. It had the advantage that it sealed all the joints. The finished thickness was only about 1/2 to 3/4 ins. I built a stud wall inside and used insulation with a vapour barrier over the top.
If you are going to use the foam, it needs to be above a min temperature, not a winter job. Make sure you cover everything with plastic sheet, wear respiratory and eye protection. Also check with your local recycling that they will take the spent canisters for disposal. I found that towards the end of the spraying the mixture went out of ratio which resulted in some soggy mess. Don't think I would use it again.
