We are having a lot of problems with MOLD. I have particularly noticed this on white painted aluminum window frames.
We are located in Citrus county Florida. We see some very humid summer days here. The windows were replaced about 10 yrs ago. Original White finish has beer painted over at least once. I would like to put a white finish on these surfaces that would NOT mold!!!!!!!!!!!!!!!!!!!!!!!
MOLD, we see this everyday if you live in Florida! The RH% humidity is high in our climate area and if it’s not controlled properly indoors it could have a devastating effect on your home's building envelope and your health.
First how does mold grow? Simple, it needs water, air, and dirt. So what type of mold do you have or does it matter. I believe it’s hard to tell unless you spend a bunch of money having it properly tested.
Your question is in regards to mold on your windows with all the ”!!!!” was not very clear so I will do my best to help. If the mold is on the outside of the window frame I would consider cleaning the area and use a UV/ mold resistant satin paint finish.
- If you did this the first time 10 years is about the life of it unless you upgrade the windows to vinyl.
- Check with a local paint supplier they should be able to guide you on the best type of paint for this.
On another note: If the windows face South they are usually the most affected unless irrigation is spraying to close to a window.
If the mold is growing on the inside of the window you have a much bigger problem. If this applies I would consider calling an A/C contractor first, insulation contractor second, and a window contractor third!
I hope this helps good luck…
