How to kill mold?

Thicker stickers (3/4 min.) get a fan on it asap…when the surface moisture is gone/lower the mold will die. I don’t expect it to stain the wood any deeper than you are going to surface plane off anyway.

We have access to a product called KILZ.
Made for the elimination – prevention of mold growing.

It is in a white spray can, you could give the existing mold a coating, it will not really penetrate much, but seal the mold from spreading and would be easily planed off when you go to work with your lumber.

As suggested, a fan will keep the air moving through the stickered areas, and it should not spread.

Greetings Gary,

Just use bleach and water and a scrub brush…... Mix about a 1/3 to a 1/2 cup of bleach in a gallon of water,
stir up good, and scrub the moldy spots….... should take care of the problem…..
Like the others said, get a fan….....

I’m with Rick, Bleach diluted with water. Although I would just put it in a spray bottle and spray it on. It should kill it, if not on the first spray, spray again, wait about a day before checking each dose and if not completely gone after the second dose, then a little scrub brush. You just need to be careful with a brush because you don’t want to make the mold airborne, that’s what makes people sick. My $.02

Greetings childress,

Very good sugesstion on the spray water bottle… I said a gallon because he didn’t say how much wood
he had mold on…. thanks for covering me on that one…!!!
Also… I’ve done this on plywood that I got from the lumber yard where I buy… you have to check the wood

Probably bleach water solution will take care of it. I would recommend getting some 3/4 or 1” stickers and either stick it outside where it’ll get lots of air or put a fan on it inside with a dehumidifier. Its not getting enough air.

I would not use bleach…even diluted on walnut…

Diluted household bleach will kill the mold and shouldn’t have any significant effect on the walnut. You will be surfacing (planing, sanding) the wood when you work it anyway.

Vinegar is a pretty good mold killer and is a little less caustic to the user than bleach. I have never used it on Walnut, so I can’t say how it might react.

Vinegar will most likely react badly with the tannic acid in walnut (turn black like it does oak)

I would be concerned using bleach on wood I would suggest naphtha after some warm soapy water and letting it dry before using the naphtha.

Thank all of you for the nice welcome and the great ideas. When I got home this afternoon, I pulled each piece outside, put on my mask, and started scrubing with a long handeled brush. The mold came off easily, but as you noted, I have restacked with a fan behind the lumber and this weekend I will do it one more time and I will cut some new three quarter inch stickers. I also had some quarter sawn honey locust that I had stickered with some old redwood stickers and some pine stickers. The redwood was putting a yellow stain on the wood while the pine was fine. Both species of stickers are completely dry. I don’t know if anyone else has seen this before. Once again, thank you for the help and the friedly welcome.
