Just finished putting up a new shed which is on a (new) concrete base with a rebate.
I noticed the other evening that the inside of the roof was covered in condensation. I did a bit of research and this seems to be caused by excess moisture in the shed. I'm hoping this is just because of the newish concrete base which has probably not completely dried out yet. Has anyone experienced this before?
The shed is to be a primary outdoor storage location (as we don't have a garage) so I'd like to improve the weather tightness. I don't expect it to be 100% water tight but has anyone got any suggestions on how to improve the situation?
Current issues I've identified;
1) The shed roof has gaps where the roof meets the walls. There is an overhanging eve but there are gaps that would let air in.
2) Where the shed walls meet the sheets overlap (at the corners of the shed) but there is a gap as they are not screwed together. The instructions suggested filling these with some kind of compound.
3) The doors are not water tight
Anyway, I was thinking of using expanding foam to plug up some of the gaps. Good/Bad idea? Any better ideas?
Thanks
