If this happens it would be with the M100 - a machine which was designed for plastering. How something like this is organised is a tricky one and will take some planning.
Agreed with a few points that various people have made. Mainly a sensible one from
@CeeVee - as a system it won't be beaten.
But the point of this is the speed of application, no matter the material the output will be the same. Whether Multi is the best for this or not is t the question. We always state and say that the machine applied plasters are far better and are more suited to this.
But, due to availability many guys still choose to use Multi.
Therefore it can be done and guys do it for a reason.
As I have said hundreds of times, everyone can be the Hero and lash the material on at 100mph - the machine can do the same, the difference being it can do it all day everyday! It's simply impossible for a human to be able to do this.
The process or 'system' between hand and machine application is very different. 90% of spreads two coat, with the machine there is no need as you get the required thickness of material on in one pass
Also, tools used when machine plastering are products such as the Speedskim etc - large spats etc designed to cover large surface areas making a fast process!
There is no doubt that a man can start getting gear on the wall quicker to start with as it takes time to set a machine up.
But, once you crack a bag in a machine it will mix it and spray the whole bag in around 2-3 minutes - Yes, mix and spray the whole thing in less than 3 minutes!
