There is an optional mixing unit available which will mix Hardwall and Scratch Render. The Output is pretty much the same as the Ritmo so your not losing out at all. We have something in the pipeline so it will be a fair bit quicker soon.
As Price says its a great machine as a stepping stone into the machine world. If your doing loads of m2 of Hardwall and Render we would always recommend your first option as a 3 Phase Machine.
Saying this, the EZE 24 is more than capable of packing a big punch for its size and can cope with what is required.
The hard part of the job is getting the gear on the wall. Thats what the machine does!
