oiling timbers w/ "mildew" spots

[beenthere]

Don't do that Don. Your info was very good, and covered some of the basics. A good indication of conditions at the time the blue stain happened. Getting the wood out of those conditions will help keep it from rotting away. The blue stain in dry wood isn't a strength problem, according to what I've always heard anyway.  

Some of the advertising hype that can get bantered around might lead us to think we should buy more chemicals to treat the wood for something it may not have to begin with. But if it sells treatments, that is priority to the mfg.

Not following your last post, and what it is you are referencing to...

i.e. "this stuff"

"lighter instances of it.."
"..it's very common.."
"...start to get it"

Mildew the "it" here?  or blue stain?

Just curious.    

Oh, sorry!  I was talking about the blue stain. 


Engineer:  I'd like to see pictures of your floor.  As mentioned, our 2x T&G flooring (forming the 2nd floor and ceiling for first floor bedrooms) has some light instances of the stain on them, but it actually doesn't look bad.  I think perhaps because the T&G was dry, as opposed to the wet timbers.

I read and just thought "the beginnings of rot" meant even if the timbers were housed/protected, so I did get a bit worried for a minute.  Here I was, picturing our timber frame gradually getting weaker and weaker as time passed.    ... but I now understand it to be that the wood will rot IF left in those original conditions that caused the blue stain in the first place (left out in the weather).

I think I better hush and leave it to those more capable

  Nossir, don't do that!  I appreciate all the info you guys give, as always!
