Hey folks,

Just bought a rather pants cheap shed (need to spend more next time!) and unfortunately there are gaps galore in the paneling. I need to seal these gaps to prevent water getting in. I have creosote for the exterior surfaces, but was wondering what I should seal these gaps with?

I was originally thinking silicone sealant? But I'm not sure how that'll do sticking to the shed.

Any help would be much appreciated :)

Many thanks!

Matt.

Is it one of those sheds with the rough sawn boards overlapping each other? Are they the gaps? As I don't really think there is much you could do to seal these as the boards will expand and contract quite a bit.


Silicone will stick to the shed, but I'd use it before creosoting it as it wont stick to creosoted surfaces.
 
It's a tongue and groove shed, so no real large gaps in the panels just a few small ones where the wood has warped. I think that I'll have to attempt to get sealant in to those gaps too.

Thanks for the advice on the silicone! I will give that a go before creosoting.

Thanks very much!
 
Creosote is great stuff, managed to keep my old shed rot free for over 10 years! How did you manage to get some as I thought it was banned? I absolutely love the smell as well :D.

You shouldn't really have any gaps in T&G boards. But with it being quite warm and dry recently you will find a lot of the gaps will close up once its damper. The boards are designed to allow for movement as the weather changes, so not a good idea to use anything hard to fill the gaps. I'd say silicone would be ok to use, but someone might have a better solution.
