shed question

[salome2001]

sorry if this seems daft/ OCD, but I'm putting up a shed from pre-owned panels, I've had to make a new floor, which is OSB3 board. My question is: is there a way to waterproof/ seal the edges of the board to stop water getting in and soaking in to the chipboard? I'd thought of felt roof flashing tape around the edges, DH thinks duct tape. Is it even necessary?

Advice from previous shed- constructors appreciated

(nb. yes, shed floor is elevated off the ground, with underfloor joists standing on bricks on the dirt)

hmmm, chipboard not ideal. I used boards scavenged from old pallets on my shed floor and then covered with thin ply.

the OSB3 board is labelled for exterior use and was apparently the original floor of the shed?!?

(there is a part of me that really likes the wood floor idea. Maybe sanded and stained I do have access to a quantity of pallets so its not out of the question, though I have found it almost impossible to deconstruct pallets, the ones made of decent wood tend to be impossible to remove the nails from...)

my shed had an osb floor I put my foot through it
waste of time I had to put a new one in after a few months

I did the new floor in plaster board pallets .you could just nail the timber boards on top of the osb and nail through to the joists before you put the shed up as the walls will sit on top of the floor

I found the smashing the blocks out of the middle of the pallet first with a mattock the best way of breaking them up
then stand on the pallet and smash the cross rails off the back using the mattock as a nail bar ,

they use ring nails and they only go in they are not designed to be pulled out
I snip the end off the nails with nips an leave the nail in the wood

sounds like a good way to get out some latent aggression!!! I am thinking v seriously about doing the timber boards on top.... good ideas...

You could use creosote or bitumen to paint the OSB for the floor, that would certainly make it weatherproof for some time. But I concur wholeheartedly with what the others say about it being naff as flooring, and using pallet boards as well/instead.
If you have not broken up pallets before, I would say be sure to wear thick workgloves and maybe even safety specs depending on how you are cutting the nail ends off; and last but not least, be careful when you are giving it laldy with whatever swinging tools you are using, it's the sort of job where it is well worth setting up the pallets beforehand so that they are securely held and things aren't bouncing around. I've seen a few injuries to kneecaps etc (none serious, happily) during pallet demolition, caused by too much force and not enough predictive power. Personally I love to use big, BIG levers.

I thought creosote was banned a few years ago.

Yes oldie, I should have said, "creocote" - I've got a container of it here, and according to my eyes and nostrils, it's the same as the old stuff, near as dammit. Maybe a bit more runny. I wouldn't normally buy anything that toxic, but since I inherited it, and it has been manufactured, and the local authority no longer put it into landfill separately...might as well use it.
