How weatherproof is Sterling board?

They have a shiny and non-shiny side, don't they? Is one more waterproof? If used as the outer skin of a shed, how long would it last?! What if it were also painted?

Exploring options for a practical storage shed for a local group. I know it ain't pretty stuff, but at least two of the sides would be pretty much out of view, and something like box-section metal (roofing) sheets could be used for the 'nice' sides.

(Trying to cut both cost and assembly time).

Cheers.

It’s the glue that makes it water resistant, I’ve seen it used for a shed, painted and it held up well.
 We use it to protect driveways after a few months it does start to swell however it is getting the full force of nature.
 I think painted and off the ground you should be fine.

My wife was given a few tomato plants about 5 years ago, and told me to build a raised bed for them. I had a few old bits of OSB hanging around, so made the sides and base from them. Told her it would probably only last a year or 2 which she was happy with.
However the base has only just gone this year. Must be the high standard of joinery I did.

For the price of it, you might be better with sheets of Hardiebacker for thebexposed but hidden sides.   That's not going anywhere. 

The quality of your ply will matter.   Shuttering ply would start to peel.  

Perhaps baton your OSB before applying the box section stuff.

I used osb board to change my old timber garage into a storage shed (boarding off entrance & just have a door) about 5 years ago. It is still solid. Give it 2 coats of a cheap primer sealer making sure edges are well coated, about £7 from screwfix. Then a coat of any paint you like. If you can keep it off the ground (sit on some 3X3 timber) it will last ages

Thanks all.

So, if painted it should last pretty well? As these sides wouldn't be seen, it wouldn't matter if they were coated in roof paint...

Interesting, Doozer - that's quite cheap. But isn't it brittle? Couldn't it just be kicked in?

Not if you build the studs @ 400 centres wouldn’t add much to build cost!
out of my depths here on how you would stop water getting into joints though.

Should be easy enough to seal between the sheets as they are butted up for fitting.

Have you tried even drilling a hole in it?   It's solid and as heavy as anything.  

Admittedly, I've not tried or seen anyone on site trying to kick in a piece of cement board, but I can imagine you'd get a rather sore foot before anything else.

Sounds as tho' it would be a sod to fit, then :-)

I used to fit it in bathrooms for a plumber got a dedicated blade for my saw, and it eats drill bits
