Making Shed water proof.
Hello there. I am quite confident about how to make a strong and stable shed but not about making it watertight. I'm just not sure about how to waterproof the four exterior walls, corners and also the bottom strip of cladding.
I have viewed some garden sheds and they seem to be fully clad on one wall and the adjacent walls are almost fully clad except they have a thin wooden strip running their height at their edges, the strip which makes up the four corners of the shed and the strip which touches both the cladding from the fully clad wall and the adjacent wall which is fully clad minus the inch or so which is left to house the strip. I would love to go ahead and start this right now, but I can't see how this strip covering the joints of the four walls will keep the water out and feel there must be something inside the wall to wall joining that I'm missing.
Also, in regards to the bottom most strip of wall cladding, which passes the join between wall and floor, is there any need for a waterproof barrier? So is there any need for a barrier between the bottom-most piece of wall cladding and the framing of the shed?
Hope I have made it clear enough.
Thanks for your time, James.
