How do i mix off white wet dash harling? my brother says chips, sand, snowcrete and little lime but i am unsure as of how much of each i should use. Any help will be much appreciated.

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

first coat 3 rendering sands ( not yellow building sands) 1 lime 1 snowcrete second coat 4-1-1 apply stone chipping to wet render (apply wet chipping)

hi alan,i usally do a scratch as normal without waterproofer let cure for two days.second coat render smooth then flick on yer chippings.ratios two chips,two sand,one snowcrete,one lime.lightly flattern with tile pad.good luck.
