My
company name is *** Services and we do a lot of special projects contracts
with a large university here in ***, Florida. The problem they have,
all over the sidewalks, are stains from the golf carts. The batteries in the
golf carts are charged every night and batteries produce sulfuric acid, when
they drive the golf carts in the rain, the rain water runs into the battery
compartment and then on the metal parts of the golf carts. This produces a
rusty, bloody looking stains all over the concrete, especially when they
park the carts in front of the buildings. If it is raining, they park
that much closer to the door, the stains are horrible looking. Will acid
stains cover this stain??
This is a very large project; there are miles and miles of sidewalks.
Can you help?? Get back with me ASAP

Sounds
like a tough problem. The stuff you describe sounds nasty, and any kind of
acid will eat the concrete. Rust stains are very difficult to remove,
and probably impossible to prevent on sidewalks.
Is that a common problem at golf courses? I am not familiar with
that as a "golf" problem.
The one sure way to prevent that would be to "impregnate" the concrete
with epoxy based sealers. But that will probably be substantially more than
the original cost of the concrete.
If this is a problem of appearance (not structural integrity) you may
want to consider staining the concrete with dark stain that will make the
problem less evident.
Sorry, but I don't have the magic solution... |
