Hi i was wonderring if anybody can tell me how to get plaster and plaster
dust of my block paving on the drive, hosing it does,nt seem to shift it.Is there a way of getting it up.

Pressure washer but even then it can be hard to shift once set but it will eventually break down due to the effects of rain & frost; moral of story is always hose down after each mix.

As said above, it is water soluble and will go with time - however you can speed things up by soaking and scrubbing with a stiff brush. Then cover the area with hessian or sacking and keep it wet for a few days . The scrub and hose it again.

Water and elbow grease.

By the same token , we always try to soak our mixing buckets overnight in water and it keeps them spotless.

Would brick acid not help?

No. Gypsum plaster is at the red end of the litmus scale.
