Natural wood gets texturized to look like salvaged barn wood. UFP-Edge® Natural Rustic Trim Boards are new lumber that's been surface distressed at the factory. The surface is rough.
Kiln-dried boards are not sealed. You can paint or stain them or leave them unfinished.
These boards should not be used in outdoor installations. If you take your chances and do it anyway, manufacturer recommends using a wood protector sealant.
Installation notes. Boards match this Natural Rustic Shiplap in case you want to create a cool accent wall. In bathrooms: Seal boards with waterproof sealer. Shelving: Use with proper support.
