Rust Stains On Concrete Floor
This isn't something that you're
going to see too often, rust stains on a concrete floor. This picture
was taken after a roof leak, forced the homeowner, to remove the
carpeting, because it wasn't drying properly and the carpeting was
starting to mildew.
Obviously you're only looking at a section of the concrete floor slab
that is stained. The only areas that were stained, are the areas where
moisture sat for a long period of time. This isn't uncommon, for any
water damage, with in your home.
Moisture will often accumulate in the low spots of the concrete floor.
Now for the million-dollar question, what is it, that actually caused
the concrete floor to stain? I really don't know, there could have been
metal filings in the carpeting or underneath the carpeting, the concrete
company could have used a rock or other materials, in their concrete
mixture, that could have stained the floor.
Home Repair Tip: You can use vinegar to remove the stains. Pour the
vinegar directly onto the concrete areas that are stained and let it sit
for 15 to 30 minutes and you can repeat the process, until you are
satisfied with the results.
I don't think this would be a big problem, even if you just cleaned it
up, let the concrete dry out thoroughly and then re-carpet. The stains
were obviously darker, when the concrete floor was wet and seemed to
lighten up drastically as the floor dried out.
