Hi Ox
I am Oxfordshire based, give me a pm on here and we can keep in touch. Always good to network, I've always got a fair bit on so once you have completed the course give me a shout, I might have something to help you out with

Andy, I see youre just around the corner from me and I'm in in the sanding business as well. If you pm me, I am happy to give you some advice about what setup you will need and what actually works or I'll even come and do it for you and you can give it a go yourself so you can see what you need...
That will work but you might want to consider dust extraction and ask them to supply diamond cups for that STR because sanding pads wont be sufficient (in my opinion) 180sm should be 2 days work (ish)
good luck
I am based in Oxfordshire and see you are in Berkshire, I am happy to come and take a look and give you a quote for the sanding if you like
PM me if interested
Many thanks
Mike
Why the need for such an arrogant response? I know you are a very well respected member from the screed industry and I wasn't trying to pick a fight! I was saying that this was my personal method of laitance removal from liquid screeds. I have invested a lot of money in sanding equipment...
If you removed 1mm of laitance, you would be down to aggregate
There is a lot of conflicting advice as to how much laitance to remove but personally I take off enough to expose the aggregate then prime with a good quality primer sticking a anti crack mat down with a gypsum based adhesive then...
60 grit sanding pads wont be enough for sanding off laitance
Copper disc or diamond cups will do it but you may need some dust extraction depending on how dry the screed is
This is something I have been doing a lot more of and have invested in some good gear and have opened up another business...
