Don't leave out the Scottish and the welsh .i have not done this in decades so cannot advise, surprised at no hydrated lime been mentioned though
i mean the sand/cement mix you use to apply the coat before dashing. stuff thats left over, shovel it into the dash mix, acts like mortart mix

Car in Ireland is Carr ,mortar is just another work for muck that brickies and spreads use all over. Different usage in Helmand
when we do roughcast, wet dash, slopdash.or what ever you want to call it.
we run 2 cement mixers one for dashing mortar, the other for the roughcast. if not you will be washing out all day.
we scratchcoat.
dashing mortar with lime and extra feb mix to make it extra fatty.
roughcast we use ballast, with extra stone added if required.
it is very heavy work so good luck

you do have to protect the windows, but try and dash on the wall!

have dry dashed hundreds of houses cant ever imagine using ballast for wet dashing sounds proper messy.
whats your mix
5 buckets of sand 1 bag of 25kg cement half bucket of lime for the under coat. 4 buckets of chips 2 buckets of sand 1 bag of cement half bucket of lime for dash. Hope this helps.

It happened to us with pebble dashing, even though we very rarely do it, looks horrible
whenever we have dashed for permaroc they have supplied a quality flint, not a cheap stone with imperfections. you get what you pay for !
