I intend to use quarter to dust granite chips mixed with sand/cement to match existing. Is this mixture correct and what ratio?

Hello onion!! Would you be able to give me some advice on a slurry dash, been asked to do one but never done one.
Or if not the type of thing to be doing blind would you be into giving a metre rate on the job???

scratch coat as normal, let dry for a few days,plaster a light coat of rendering before dashing ,for a large job get an old bath for holding dash.mix enought to do job,the reason for bath is the dash will be the same colour when dry plus a wall uses a lot of of dash.you need a few buckets,quarter fill wet dash from bath into buckets. using a small coal type shovel dash the wall.(maybe a dasher can be bought) they are not difficult to make.
