dried paint off of concrete

That thing goes off....the walls will have no walls.....

I have a gallon of some sort of bacterial or enzyme based solution. I will say that I did use it on the shop floor and it removed roughly 35 years of oil stains satisfactorily.

The enzymes usually work on organic stuff like blood etc. which is why it's the weapon of choice when cleaning ambulances, hearses or cars with persons rot and died in them. On paint that may not even effect at all.

my gf who worked on er for many years says that's not entirely accurate as to weapon of choice.  then again we dont live in the same country, so what is used in yours, may not be what is used in ours, or in our region as a matter of fact.

They're probably not used in ERs where the stains are fresh. If something has rot like a cadaver, the stench is almost impossible to remove unless you use an enzyme based special detergent. They say that even that won't help if someone died in their car - it will smell like death forever.

Believe mythbusters did that with a pig

This stuff is made specifically to eat up oil and oil based stuff.

I've read about those! It's amazing how enzymes and bacteria can change their digestion to utilize stuff that would have killed them some generations ago! If and when the human race will remove itself from the food chain, nature seems to have the ability to heal itself in no time. Just think about what kind of a paradise some space travelling aliens would find after we've left... With some luck they'd be some ammonia breathing turtles accustomed to a sub-zero climate, wanting to make it like home.

paint a 109 over it.

next problem!

This. Completely chemical free and safe unless your an idiot and burn yourself

Rot.  Use MEK (Methyl Ethyl Keytone).  It will remove the paint but will not eat any of the concrete.  Use gloves, you won't believe how this stuff can dry out your skin.  Put the MEK on a cloth and scrub the paint off.  As the old paint gets on the cloth, put more MEK on a fresh area and do it again.  Keep "turning" the cloth or you will just be smearing the old paint around.

Thanks everybody.

Zoney I'll have to check that out.

I'm thin on time lately, maybe I can research it this weekend.
