Good evening everyone,
After visiting three home improvement stores for advice and still feeling unsure (since I received three different recommendations), I’m hoping to get some tips here.
We have removed tiles from the floor. What remains is the tile adhesive (see photos). Using a 7cm (3-inch) wide chisel hasn’t been very effective because the adhesive is extremely stubborn and doesn’t come off easily. The adhesive is about 3–4mm (0.1–0.15 inch) thick and covers a spacious area of 70m² (750 sq ft). Afterwards, 60m² (645 sq ft) of parquet flooring and 8m² (86 sq ft) of tiles will be installed here.
What would you recommend? Many thanks in advance!

@knifflig that is a cup wheel for the angle grinder. You use it for corners where the big grinder can’t reach. It’s not suitable for larger surfaces; you’ll end up filing by hand. Especially since dust extraction doesn’t work perfectly with those tools.OK, but does the larger machine have something similar attached?
1979 was a good year for asbestos.
Do you need the 4mm (0.16 inches)? If it's that solid, you can simply tile over it and that should be fine.
However, if it still needs to be removed, you will need a concrete milling machine, and grinding should be done only at the very end.

If you want to be sure, just send in a sample before sanding.
This usually only costs a two-digit amount.
However, it only makes sense if you are prepared to take the necessary steps if the sample results are positive.
That means a very expensive specialist company, and so on.
I would sand wearing a mask and protective suit, and that should be enough.
@tomtom79 you can’t tile over that. Either level everything with self-leveling compound or sand it down. Depending on the surface area, 4mm (0.16 inches) is quite a lot of (expensive) leveling compound.

Thank you. I was at Boels today. Sanding will cost me about 500 EUR (including vacuum) or 700 EUR if I’m unlucky and the sanding blocks aren’t enough. The leveling compound will probably cost more and has the disadvantage of a higher build-up.
I will wear a mask and, based on your recommendation, also a suit (but what exactly is this for?).
