Paint removal

I dropped a tin of paint this afternoon. Fortunately this occurred outside. The paint is oil-based primer (red oxide). The surface is some sort of concrete. How am I supposed to remove this?

1. B&Q suggest white spirit but I cannot see this working after the paint has dried.

1. Steel brush attached to power drill?

2. Nitromors?

1. My favourite - flame thrower (as used for clearing weeds)?

Paint the rest of the concrete red. Or overpaint it with a more acceptable colour.

Is red oxide lead these days? If so, burning it might be a really bad idea.

Is this a nice smooth concrete - maybe even polished to a glass-like finish? Or rough like many drives and roads - purposely made to stop them being too slippery?

If it is rough, you don't stand a chance of removing the paint. And any attempt might end up worse than it currently is. I agree with those who suggest painting over it.

Pressure washers are very good at getting things off surfaces, I haven't had to try it on paint but it would be the first thing I'd try - once the paint had fully dried. Anything chemical is likely to make a smudgy mess.

I removed some white paint from concrete with my quite powerful pressure jet washer.

If it is solvent-based then some of the paint will have been taken into the concrete.
