the mix was done with snowcrete Dave thats why it looks so sandy it is actually 7;2 sand to cement with sbr bond added to the mix the tiles are bedded with snowcrete and sbr bond slurryit sounds like he needs you ,and not the other-way round ,so bump the the price -up for him and let him know why, .
just a small observation gary ,the screed look's very sandy to me ,but i know it must be the the sand,as i know you would have used the right mix, so what mix did you use? great work by the way mate!
