I'm going to cut into free flow screed, but in the part of the world I come from where most of the work is for smaller builders barn conversions etc, and trying to educate some of these old boys or the public for that matter to modern renders is hard going, sand and cement it is for us for inside and out. We're about 20 years behind in somerset. But I want to save my body a bit so need a machine compatible. I have somewhere to store one I'm guessing towable is the only answer for a decent screed delivery and site mix capability.
