first coat 2 plastering sand 1 sharp sand 1 cement,don't incorporate waterproofer in this coat, rule and leave with a combed finish ready for second coat.
second coat 2 chips 2 sand 1 snowcrete 1 lime mix together to achieve a mix similar to very wet concrete,then apply using a small coal shovel flatten sides of shovel to get better spread, put waterproofer in top coat as with a wet dash/ slopdash you need suction when applying the top coat in order that it doesn't slip
