has anyone experimented with a homemade gunnite (concrete applied with air pressure) machine? Answered

It cant be too different from drywall texture spray rigs.

 Those machines have some pretty crazy air pressure! What kind of compressor do you have???

On the other hand, you could make a concrete slinger. 

You'd hold the handle and 'sling' the concrete onto the wall...

It is too hard to do. Get a shovel full of sand and cement, feel how heavy it is. You and I do not have a compressor big enough to blow that stuff thru a pipe. All a gunite machine does is blow sand and cement on to a wall while water is hitting it too.
