Prepping Anhydrite Screed

[flappy]

Hi All,

I have a floor tiler coming in in a couple of weeks time to lay ground floor tiles on an Anhydrite screed. He’s going to do it properly and has tiled to this surface before. We have to clean up and lightly sand the surface to ensure there is no more laitance etc. What sanding kit should I use for this? I’ve contacted HSS etc and they say their sanders are for use on wood and I’ve had no useful information.

Any ideas on what to use?

You can use a floor belt sander with a 60 grit paper belt , get a few of those belts.. Also best not tell the hire company what you are using it for , as the anhydrite dust clogs them up a bit lol lol ...
