在裸露的框架上摆脱霉菌
建造新房子。框架几乎完成。屋顶将在下周结束。我们下雨了。我今天去检查了进度，发现许多木梁和2×4带有模具。整个楼梯的底面是发霉的。我假设这对于昂贵的新建版本不正常，对吗？此时该怎么办？我有点害怕。谢谢。

您可以用刷子机械地去除模具，然后进行霉菌处理。等到您有一点干燥的天气，否则它可能会回来。
Don’t worry about things structurally though, the mold won’t affect the strength of the wood.

I’m not worried about structure. I’m worried about getting sick from mold on the framing. I’m super allergic to mold and I’m worried this house will take me down. It seems pretty crazy to me that we are paying
接近1美元的磨坊，木头上都有霉菌。
Mold is a natural occurrence in wet weather. An abatement company could clear it all out once you have walls and roof up, then keep a dehumidifier running to dry things out so that it doesn’t come back.
Bill
I've got a serious mold allergy too and built a house in the very wet PNW and of course wound up with mold on the framing before the roof was in place. I too freaked out a little bit but in the end it was no big deal. Standard approach of a little mixed bleach, water, and dish soap took care of it and no mold since.
Mold on the framing is pretty common at that stage. Mold needs moisture to grow, and once the roof is on and the windows are in there won't (or shouldn't) be enough moisture to keep the mold growing. Clean it up and it'll be like it never happened.
请不要使用漂白剂。使用混蛋或类似产品来挤压模具。它似乎不如漂白剂令人满意，但实际上杀死了它，而不仅仅是使它看起来像消失了。
醋也可以使用，您不必使用漂白剂。
Bill
这是正常的。
室外空气中充满了数百万个霉菌孢子，它们需要一个食物来源（EX，木材）以及恒定的水分才能生长。霉菌不在乎木材的昂贵。
一旦屋顶和窗户就可以用漂白液清洁，然后继续前进。
事实是，霉菌无处不在，您无法逃脱它们。
Mold requires moisture to grow it would be a good idea to get a dehumidifier running in your house as soon as the windows and doors are in.
Most new construction homes should have a dehumidifier for the first year.
If you can keep the humidity under 55% I do not think you will have a mold problem.

Should we have a dehumidifier on each floor to get the house to dry out faster? And don’t we have to remove the mold from the wood? I think it would create huge problems if we didn’t.
More dehumidifiers will speed up the drying process as long as they don’t cycle off. At some point you reach a limit and more won’t speed things up any.
You can get mold killing primers that can be painted over mold. It’s better to just remove it when you can though.
Bill
But how do we remove mold without taking apart all the framing? It’s half the house of wood. No exaggeration!
Get what you can. The usual way to do the work is to use a brush on a pole, and brush off the worst of the mold (wear protective gear when doing this, and especially a respirator). After that's been done, you spray what's left with a mold treatment to kill the remaining mold. The last step if you want to be extra careful is to paint the area with a mold killing primer (I've used one made by Zinsser in the past) to help keep the mold from coming back.
The most important part is to eliminate the conditions that allowed the mold to grow in the first place, and that's moisture. Once your home is far enough along that it can act as something of a box for air (i.e. walls, roof, and something over the window and door openings), you can start running dehumidifiers to keep moisture levels low enough that the mold won't grow.
If you're really concerned, I would have a painter come in and spray everything with the mold killing primer after brushing off the worst of it. You'll end up with white-painted framing everywhere, but you'll know that all the mold is dead and encapsulated so you won't have to worry about hidden mold once your home is complete and you're living in it.

我很感激并理解您的关注，但我认为您可能会误解霉菌的性质以及它如何影响房屋中的木材。这并不是说如果您打开冰箱，并且在剩下的三明治上发现霉菌，必须将其扔掉。木头上的一点霉菌不会毁了它，并迫使您拆除房屋。实际上，我很确定每个房屋中的所有木材都至少都坐在上面。木材上的模具只有在以高速繁殖并喷出孢子的繁殖时才会成为一个问题（尤其是在封闭的空间中，您更有可能呼吸其中的大量）。
如前所述，一旦条件不那么成熟，水分就不会繁殖。可以选择清洁剂或机械手段的大部分表面模具。之后，一旦屋顶打开并且窗户就在其中，您不应该再看到霉菌的生长了。
I personally think that painting over the mold affected areas is overkill and unnecessary.
事实是，霉菌无处不在，您无法去除所有霉菌孢子，您能做的就是防止霉菌生长和繁殖。
化学物质会损坏一些孢子。油漆可以密封大部分孢子。

All the advice above is helpful. Treat the issue yourself or hire it out.
