Waterproofing wood outside

[5oysterman2]

I want to put up a wooden shelf in the garden using off cuts of either OSB or t&g that i have got. What can i use to seal it & prolong the life of whichever wood i use for the job.

Providing you don't put them perfectly levelled so water can drain off, I would use 3 coats of Sadolin Classic Woodstain.
Plenty of shades to chose from.
Will need attention every 3 year or so if totally exposed to the elements.

The osb will be trickier to seal and probably won't last as long as the t&g. Any garden wood paint will do, but boiled linseed, danish oil, IKEA Trixig.
Oil is a quick and easy option, top it up annually.

What is the shelf for? Only MDF and chipboard would be a worse choice than OSB for an outdoor shelf, if longevity is a concern.

It's too put a large flower pot on. It's going on some cut down tree stumps in the corner of my garden.

It's going to be T&G off cuts from a shed i had built.

Pallet timber will last longer and free.

I've already ready got the offcuts in shed taking up room.
