Use two size trowels to build up/flatten?

Guess I can make a rake screed 🙂

If you're tiling onto old residues of unknown glues/adhesives it's probably best to seek a locally stocked levelling compound that's suitable for this application. I think Ardex make one. If you tile straight onto it with adhesive you run the risk of it de-bonding unfortunately.

I used SIKA primer and self leveling compound combination is approved for installation over mostly removed adhesive. Regardless pretty sure I have now ruined my floor... looks worse than it was before the attempt ()%)(%#. There are ripples. I probably did not mix well enough as I was afraid of the short work time. I seemed to have to work it much more than just a pass with a screed like in videos. Partially because this isn't a plain rectangle it's a hallway with a doorway into the kitchen, cabinets and an island in-place. Pretty pissed at myself and not sure now what it's going to take to correct.

I think it's time for a few pictures so we can see what were working with

I'll set aside my ego and attach them knowing full well there me be some laughs.

The coarse ares were clearly not properly mixed compound. Shouldn't be too hard for me to grind them down as well as other small places. The overall unevenness and the butchering of edges I think is the bigger problem.
