cheers micilin when you say dead or greedy do you mean not workable enough? and adding the soft sand makes it more workable?do you ever mix your sands ? say 2 sharp 1 soft, or 2 plastering 1 soft?
Steve, yes , if it is a too coarse. Sometimes it's a little dead or greedy and a bit of soft in the mix gives it a bit of life.
You're still not making the overall aggregate too soft though if you just put enough in - but as you know that depends on the sand .
Sometimes we get a batch of 'Leighton Buzzard' that's very dead and a few shovels of soft does the trick.
