Hi all,
I'm coming to the final stages on this bench project. The seat is comprised of a couple of new scaffold boards made of an untreated rough sawn white softwood. I'll be sanding them down, but not too much. The bench is located under a canopy roof, so it will not be rained on, however will be subject to seasonal humidity changes and temperature etc.






I've never made anything like this so need to know what products to apply to finish the wood. My goal is to protect the boards from twisting and bending and stabalise them as much as possible. I don't want to colour it too much really. A slightly golden colour or light oak is fine, and it adjoins a cedar clad garden room. I also don't want a glossy or plasticy look. I like the idea or an oil or wax, but I'm not sure if they do much in terms of long term protection. One thing I do have in my shed is some Barrettine Clear Universal Wood Preserver which I bought for the garden room:
I've also come accross a similar product, OSMO WR Base Coat, which actually sounds similar, but more suitable:
Both of these are just a base product requiring the use of an oil or other finishing product. The OSMO specifically mentions that it "Reduces wood swelling and shrinkage" which appeals to me, but is this also implicit of other similar products, like the Barrettine Clear Universal Wood Preserver? If not, I may choose to buy the Osmo WR Base coat instead.
Does anyone have experiance of either? And what of recommendations for a low sheen product to go over the top for a bit of depth and protection? Osmo oil, Tung oil, Boiled Linseed?
Thanks for any advice

One thing I do have in my shed is some Barrettine Clear Universal Wood Preserver which I bought for the garden room:
- Contains Tebuconazole, Permethrin & IPBC.
- Protects uncontaminated timber against wet rot, decay and wood boring insect attack.
- Suitable for use on all types of timber, rough, sawn or smooth.
I've also come accross a similar product, OSMO WR Base Coat, which actually sounds similar, but more suitable:
- Extremely water repellent
- Resistant to blue stain, rot and insect attack
- Reduces wood swelling and shrinkage
- No future application necessary
- 4001: Oil-based, brush or roller applied only
