Hello,
One more detail that we have found very helpful with straw bale is that the sprayed material wraps into the fiber better and bonds better with less effort.
Normally people scoop right out of a wheelbarrow with our render gun. This saves a bunch of time over hand application.
My hobby is spraying alternative plasters and stucco pumps. If I can help with any advice, please let me know.
Best regards,
Nolan Scheid
Very much faster than any other method although the small amount of mortar in the hopper of the gun shown only lasts for approx 10-15 seconds. Have used this method on experimental building (along with hand/trowel/tyrolean flicker methods) that I am currently monitoring. Further details available.
