Controlling bluestain mould on newly cut timber
I have recently cut some green timber which I am trying to air dry. Blue stain mould has started to appear, especially in this rainy weather.
As these are pale timbers, ( elm, ash and oak) I would like to control this if possible.
I just went out and sprayed them with diluted White King - don't know how good this will be.
Anyone have any suggestions?Cheers,

Generally I think if you use the same species for you sticks or racking out this should not happen? Also try and keep them dry as possible

Good luck - I've harvested a few pale woods over the years, with varying succes. The last lot I got was from a tall stump of crapiata that had been left standing for several weeks in the weather before I got my hands on it. It is just about completely blue. Fortunately, the fungus lives on the free carbohydtates & doesn't chew up the cell walls like some other fungi do, & doesn't affect structural strength, at least not initially. So my badly stained material is fine for the bench it's going into. In fact, if you look on it as a feature, it can be quite attractive....

Thanks for the responses.
The timber is very fresh and moisture content is therefore very high. It is stored outside so it's a bit hard to control the conditions.
The white king has temporarily knocked the bluestain on the head - I don't know how it will go longer term.
I agree - a lot of bluestain can look good. A little can just look dirty!Cheers,

i cut a lot of hoop pine and blue stain is a big problem with this.
i use a chemical called hylite 80 it removes the starch from the exterior of teh timber stoping the fungas from geting a grip.
blue stain is a fungas that eats the starch in the wood, i think it only starts under 25% mc and will not efect timber unday 18 or sompthing like that.
you need to dry the timber as quickly as possible. with good air flow. a fan blowing threw the stack is usualy enough to stop it sticking. good sized stickers 1" x 1".

I will have to rely on improving airflow, I think.
I have an industrial fan (1m across) in the shed - hope it doesn't blow the timber out the door!Cheers,

I am told the yanks will pay premium dollars for blue stain might be worth shipping it out...lolI am told that sharpening handsaws is a dying art.... this must mean I am an artisan.
Get your handsaws sharpened properly to the highest possible standard, the only way they should be done, BY HAND, BY ME!!! I only accept perfection in any saw I sharpen.

Spalting is much more unpredictable, and it does chew the wood up if you leave it too long, unlike bluestain. The drawer fronts on these nesting tables are spalted & bluestained - the flash has wiped out the colour on the top piece, but it shows up the spalt lines clearly.
