Hi,
The wooden deck in the photos has a roof over it, but is open to the elements on one side.
The current state of the deck material is good, and I wish to keep it that way.
From the photo you can see that the grain in the wood is still visible, so I'm guessing that it is not a paint that has been used on it but some other sort of sealant.
With that Information, what sort of sealant/paint/oil/stain should


I use on it to maintain its integrity? Is the best way to apply the coating with one of those flat lambswool applicators (like a roller, but flat)?
Thx
