What to treat wood with??

[Gotalotofpetstoo]

P We are getting ready to build a new coop and plan to use some weather boards we get collected. I had previously read somewhere in this group But of course I can't find it now, about using a penetrating something. I can't remember what it was, maybe a stain or a pesticide or I don't know what I just can't remember. The treated wood is all going to be on the outside so no direct.xomtact.for the chickens, so I can't remember if it was for keeping the wood from rotting or to kill any type of wood mites maybe? Does anyone have any suggestions or thoughts on this matter? Below is a picture of the coop we are planning on building, of otales.amu difference.

Just taking a guess at what you were referencing - boiled linseed oil. Pretty commonly used for wood finishing, often diluted with mineral spirits or turpentine so it soaks into the wood better; sometimes also blended with beeswax or an oil based varnish/urethane to give finishing effects and some UV protection. Usually needs a few coats. I coat all my wood shovel handles with a 1:1:1 BLO/spirits/urethane every year or two.

Alternatively there are many products for outdoor wood protection on projects like decks and fences, you may even find some that aren't solvent-based and won't have the VOCs.
