Our sprayers have been used to spray onto straw bale structures for many years.  Because of the powerful throw onto strawbale, the penetration and adherence have proven to be excellent.  The video below demonstrates application onto strawbale.  It’s a simple, yet very effective.

Speed of application seems quite good too. Two of us, one on the mixer and the other on the sprayer, can cover 40 lineal metres (130 feet) of 8 bale high strawbale wall in a full working day. So a building 7.5m (25 feet) long by 5m (16 feet) wide can be coated inside and out in one day. Three days (with curing time between) and the building is completely rendered. We were impressed! -Ed Taylor of Australia

In Australia, our tool is often referred to as a render sprayer.
