Anhydrite Floor Sanding

[stone tiler]

Afternoon everyone

Just wondering what machines you guys are using to sand the laitance off these floors? I'm using a 9inch grinder at the mo with a dust shroud but its starting to give up on me. Before I go out and get something new I thought I'd check with you guys to see if there was something I hadn't thought of.
Just not sure it's worth the extra cash to jump up and buy a big sanding machine for the occasional really big floor when you can hire one as needed.

A decent installer should be returning and doing it as part of the job. Shouldn't be left to us.

I hire an orbital floor sander every time and price it into the job. I always get the STR 701 and use my own tungsten carbide discs with it. There's no way I'd be down on my hands and knees doing it.

Jobs I've been on are hiring a machine from Jewsons,
Company never come back to sand.
