Is this floor Clean enough for ceramic tiles?

I've finished pulling up the vinyl tiles and did a brief mopping of the concrete floor. I was wondering from the pictures, is it clean enough to just start spreading thinset and tiling it or should I get a mastic remover to remove the excess.

The black stain is pretty much flush with the floor.

I was planning on using that bean-e-doo soy based mastic remover.

Hi!

Looks good enough for me. Use a high quality modified/fortified thinset mortar and you will do just fine. If there are "high" spots, it would be good to take a razor scraper to them and get it up as best as possible. From the pics, it looks like the cutback adhesive (which prolly contained small amounts of asbestos) is pretty well embedded in the concrete.

Don't use any chemical type removers as this may affect the bond of the thinset.

Thanks HotinOKC! Finally I can go on to the next step.

Yeah almost all of it seems to be embedded into the concrete and can't be scraped up.

Looks like I got a good weekend project.

Looks good from the pics. Make sure you use a thinset that says it can be used over cutback adhesive. It'll say so on the bag.

Uh-oh, I used a recommended thin set mortar by home depot employees, Versabond Fortified thinset mortar (white) Does that work? The tiles seem to be stuck tight to the floor for now... (been 2 days)
