Treating deck

Treating deckHere you see more of the troublesome deck.

The lines of rot you can see are where the studs that fasten the wood to the underlying steel are.

So far, I've treated a smallish section of the deck, not the bit you can see, and am now monitoring the situation.

I notice that rainwater beads up on the treated section of the deck, rather than soaks into the wood. So that must be a good thing.

    On my deck I flip the boards over - the underside was in great shape

    It would definitely be interesting to get some up. I would be worried about what might be going on with the steel under there, and inspection is the only way to know.

    I had another random idea about re-using the decking triggered by the above comment: Pull up the decking and look at the boards. Pick the nastiest side and rip that side off in your table saw so that the board is now a standard Nx2 framing timber thickness. Use pressure treated plywood and template in sections that will act as shims to bring the decking back to its old thickness. Treat and re-lay the trimmed decking, with the nicest side up. The odd board that is too rough to re-use at all, replace with garden variety framing timbers.

    Yah Tim, I got a bad feeling in the pit of my stomach when you indicated that you treated a section without first pulling it up. If I were you, I'd want to see what the condition of the steel is under those timbers. A daunting project but in my mind a necessary one. All that beautiful work you have done so far inside could be undone by leaks that may be developing.

  4. Hi Tim.

    A Big Ditto what Fred said, be brave and get some of those rotten timbers up, at least in a control area- then you'll be able to better guess what horrors may lie beneath- and therefore be more realistically able to decide what's best to do with the rest of the deck timbers in situ.

    Treat 'em by all means, short-term it can't hurt- I know from working on Becky's farm that real creosote and linseed oil is damned good stuff- but in the long term you must know that steel underneath needs a proper look-see.

    You and I both know that where water is trapped against unprotected steel bad things will inexorably happen.

    Go on, tear up a plank or two, I dare you.

    Kind regards to you and the LJ.

  5. Hi All

    So there is no doubt here....

    Don't fret, I'll haul the wood up - at least for an inspection of the underlying steel. I don't see I have much option there.

    The treatment is a short term thing that needs to be done anyway.
