Mold on garage floor...

[CorneliusRox]

So I had the great idea to throw an old rug down in my garage to park on and what not. It was great until we started getting snow and my car would get it all wet. Then it started to smell so I removed it.
Last week it started to mold on the cement, so I went out and got bleach and just poured it all over the floor and made sure it spread all over the floor. Then I let it sit for a whole day before I took the hose and pushed it all out.

I thought my problem was over, and that was on Tuesday, but when I went to get in my car this morning I noticed just a bit of mold starting to form again...

Anyone had an issue like this and found a solution?
I am thinking it is too moist in there but idk how to fit it? throw down some charcoal?

Mold won't grow on cement, Mold will grow on the dirt that is on the cement though. Take a picture for us.. Is it white and fluffy like? If so it may only be efflorescence.

My floor is basically dirt free, and it is white and fluffy, I thought it was snow the first day.
I'm at work but I could get a picture tonight.

Its probably going to be efflorescence.. I wouldn't worry about it. Look efflorescence up some time, its something you see a lot with garage floors, especially when they have the stress cuts in them.

yeah, I have been looking it up and I am pretty sure you are correct. I'll still try and remember to take a picture and I think I will pick up some solution specifically made for dealing with it. Thanks for taking my mind off of having a mold problem!

You try pressure washing it then treating the area?? Might clean it up a bit better

Concrete cleaner fo sho. Then seal it

That rug allowed for water to be pulled into the floor. As the water comes back out it brings the salts with it, creating that white fluffy efflorescence. As said above, acid wash the floor scrub all the spots with a wire brush, then seal with a breathable coating. DOW makes a coating specially for this.
Edit- Make sure the floor is 100% dry before coating, using a pressure washer forces a lot of water in. Compared to a hand scrub, garden hose rinse.

put a big fan in your garage and let it dry.

[vdubjetta02]

1.) powerwash the floor
2.) let it dry for 24 hours
3.) caulk your expansion joints
4.) seal the garage
5.) wait 48 hours
6.) park car in clean sealed garage

Pressure wash, clean and seal. I used Silikal brand product on my garage floor. You can find similar sealants for cheaper. You can a nice flake system to spruce up the look as well.

Hey Corey... I did the SAME thing! I thought it would be "cool" to have a carpet in the garage... then it rained... then it became an epic smelly fail...

I loved it for a few weeks! lol

I am not going to seal it since I am not sure what I am going to be doing with the garage in the future (expansion, move, etc...). But I am thinking now that I will get out my construction light, a fan, throw down some acid, clear it , and let the lights bake while the fan vents and hopefully it will turn my floor around.

Thanks for all the input guys!

I did the same thing a few years ago and I had a few small spots show up that I had to clean. I landed up sprinkling Comet cleaner w/ bleach (the powder kind) on the area and then got it slightly wet and scrubbed it with a push broom. I let it sit for a few min and then washed it off and I haven't had any problems since.

I did the whole thing with liquid bleach thing, but then I let water air dry in 35deg afterwards which might have been what killed me. I'm going to figure it all out tonight. (hopefully)

So, I let the construction light sit on it, worked out there chopping up some wood (to make a stand for my GT5 setup), cleaned everything up, the floor was super dry, and I dont think I have an issue anymore.

Thanks for the help guys!

When I bought my house they painted my floor and sprinkled the color chips over it. Something like this from Home Depot:

Just a thought. Not too much money and looks great when you're done.
