Water soaking through my shed walls!

FlaatusGoat

Relatively new garden shed. Unfortunately, rain water seems to be soaking through the wall and I'm pretty confused on how to seal it up. I painted two coats of cuprinol shed paint on the side that's soaking through with seemingly no improvement. Is there anything else I can do apart from replace the whole thing?

A pic of the outside would be helpful if you have one.

From what I can see the bottom looks worst.  Are you sure the walls aren't stood on the ground and the water is soaking in that way?

My new shed came with a tub of sealant especially for wood which the supplier recommended I apply 2 coats, irrelevant of what additional stain/finish I wanted to add myself. Can get the name if needed but it seems similar to this https://www.smartseal.co.uk/sealers/wood-sealer

Definitely nothing touching that part of the shed? - I've only normally had this when I've had pots etc stacked against the outside

Could you have assembled the panel upside down? On some tongue and grove panels this would cause this sort of issue.

The bottoms will almost always be the worst affected. It's where the rain running down the walls stop and gather on the bottom lip before dripping off. It also gets hit upwards by rain splashback.

Check the latter first, and see if you can put something down - coarse chippings or fake grass - to prevent this.

And, as folk have asked, is it fully supported off the ground, ideally on a DPC?

To answer all questions the said shed is raised off the ground with good drainage underneath it. The walls aren't touching anything (they're a meter apart from the adjoining fence as per fire regs) Looking again on the exterior, what I did find is on the outside where panels join the edge baton it wasn't very tight or flush. I can easily imagine water running into that joint and soaking in all sorts of ways. So what I've done is caulked all the gaps here with the brown kind of window and door frame sealant. Finger's crossed that's done it otherwise plan B is to install guttering......

I would install guttering anyway.  That will greatly reduce the amount of rain splash onto the walls.

Can we have a pic of the outside of the panels please

Looking at that internal pic it appears the panel has been installed upside down and that will definitely cause leaks 

Who installed the shed?

I used Gorilla Tape Waterproof to seal mine - shed's about 50 years old though lol. Or Gorilla waterproof coat and seal could do the trick!
