hi! i was searching information about how to work spalted maple.. and i found this.. If you ever think of trying to work spalted maple, be sure to buy fresh cartridges for your face mask. Spalting is caused by a number of fungi, and some of them will drop you like a rock. Fungal pneumonia is a real dog to treat and cure, and may be lethal. It is necessary to wear a full bore respirator, not a dust mask, when working with it, especially during sanding. It's also necessary to take quick care of your clothing and shower immediately after working with it. Those spores can spread everywhere in concentrated quantities. A disposible bunny suit would probably be the best idea to work in, and wear disposable gloves.. are this information true??? thank you... |

Woah...and I bought some spalted beech the other day... 
My instincts tell me that normal protective procedures is all that is needed, but I could be REALLY wrong....I've lived in mouldy flats before that make spalted wood seem relatively harmless.... |

It is true that there is often mold in the spalt, especially the really punky sections. Allergic responses to mold will vary, select your mask accordingly. |

[/QUOTE] Not only is there often mold in spalt, spalt IS mold so there is always mold in spalt. Yes, there is definately a risk when working with it. |

I have used spalted maple for many projects built in my shop, including architectual moldings for my own home. After hundreds of board feet, I have yet to develop any respiratory distress or disease from using the wood. I personally don't wear a mask while milling the wood, only when I am doing some sanding with the R.O.S.. Maybe our central Illinois fungus is not the type to bother your lungs?? If you follow my lead and get some kind of fungal affliction, you are own your own!  I wonder if huffing athlete's foot spray cures fung lung? chris |

Chris, Can you show us some of your architectural molding pix? That'd be a treat. Thanks |

Here is a shot of some doors. You can see the spalting streaking up from the bottoms. All of the photos I have found so far have just the stained spalting. I'll try to find some before and afters of other spalted moldings and post them. chris  |

There is a bunch. The stain really hides the gray and black. That is why I wish I had a before stain photo of these doors.  |

Possibly some of the reaction to the mold is to the living mold--especially a persistent infection. Kiln dried lumber might only have dead mold, and thus might not be as reactive. |

I've milled many a spalted maple tree with dust 'a flyin' everywhere, with no adverse effects....

For those of us with asthma, even the fragrance of wood can trigger an attack. For the rest of you, some of the particles and chemicals stick in the lungs and accumulate. The irritation over the years causes permanent changes in the lung and disease. Think cigarettes. If you search the web, you can find a lung disease named for almost any job exposed to dust. For example, there is a disease named for exposure to redwood dust, one for workers who strip maple tree bark, one for mahogany workers, sand quarry operators, etc. Better safe than sorry. |
