roughcast: is 10mm stones to big

[cooptaza]

Hi all, my first post, just wondering - I have a 32msq are to cover with wet dash. It is an old cottage, the back and side need wet dashed, the rest is already done. It was done on large chips. 10mm is the closest I can get to match the rest. Is 10mm to big, will they slide down the wall easy or sag.

Going to mix it at 4stones: 2 Sand: 1 Cement: and half of lime

The wall is already scratched with waterproofer and im gong to put on an 8mm butter coat then dash

If already has w/proof scratch then put a 6-1-1-(sand lime cement) butter coat on,
Your right with the top coat, but make it 4-2-1-1 don't put anything else in this mix Stone size should be ok,,

Does it need lime in the butter coat.
