Remove tile adhesive from the floor

Thank you for the tips! I have started the difficult process with a hammer, chisel, screwdriver, and putty knife. At the moment, it is still quite tough. But I am getting faster. On the internet, I also found the tip to moisten the glue. I let the water soak in well, it seems to help a bit. The screwdriver is my "smallest" chisel.

Does the chisel become dull and unusable over time?

Here is a photo of the first freed spots:

Why don’t you take a chisel then? Some in northern Italy also say Beitel.

Thank you, I didn't know that. In the future, I will no longer post any links. Unfortunately, I can no longer edit the post.
