Looking for information on what material to use to seal barn boards. Got ahold of some and am wanting to seal the exposed surface. Any one with ideas to share would be greatly appreciated. Thanks

Why do you want to seal them? The boards are well aged and stable.

anything you want, but one factor is that just about any finish/sealer will darken them to some extent.

What will the boards be used for? (interior, exterior?) Do you want to add sheen? Protect against UV? In other words—what is the purpose of the “sealer”

Hey this give me a idea for a new product.Barnwood board sealer just need a fancy can with some appealing art on the label.For the mix one table spoon of varnish to one gallon of mineral spirits.
I think 65 $ a gallon is a good price for the piece of mind your barn wood is sealed.:)

Use a matte polyurethane, I like rustoleum for this, and it will not change color or texture of the boards any noticeable amount. Great to seal old painted boards.

Thanks so much for those who responded with suggestions. I do have to say that the matte poly worked very well for sealing the old paint on the boards. Using these boards on an interior wall. Didn’t change the color or darken the wood to any major degree.
