If I slapped on some fibreglass resin (without matting) would it
seal the faces & edges of osb3 boards sufficiently against summer
weather - dew, odd shower, sun, light traffic etc?

Any thoughts/experiences +/- gratefully received

TIA

I've used a couple of coats of decent varnish in the past. Seemed ok.
Good on chipboard also.

Unreinforced resin is fairly brittle, if the boards flex under "light
traffic" I would worry about cracking.

I'd say the devil was in the detail (which you don't supply).

OK, tell us about the boards. What do they do, how are they supported
and fixed? What's the physical and geographical location? Why do they
only see summer weather?

Cover and protect concrete whilst is sets & hardens.

how are they supported

At the edges w screws


What's the physical and geographical location?

?? Outside, UK.

Why are you bothering to protect the OSB?

For the use you describe it will only be in use for a day or so at a time
and should be fine without anything done.

We have some OSB on the outside of the shed, and the back face is covered
in black gungy waterproof sealant and the front with outdoor paint.

Seems O.K. so far.

Cheers

Do you know what happens when it gets wet?

Concrete takes longer than that to be sufficiently strong to drive
on without cracking... Think more like a week down. Then reused
on the next bit.


and should be fine without anything done.

See above.
