we have always mixed at 5 stone,2 sand, 2 lime,1 cement. We usually mix up beforehand to allow to "sour".Cover over and leave for a week or so.
That mix passed down from generation to generation.I think 8mm to 10mm looks the best,not too big not too small.Ya the lime is super,makes it really "tackey" and brings it up to a just off white colour saving client money on white cement and white sand.
