A few weeks ago I posted a question regarding getting rid of ceramic tiles.
Thanks to all who posted their answers. * I appreciate it. *I elected to use
a hilti and floor scraper.

Now my problem is getting rid of the dry glue and dealing with the cement
floor.

This is a basement hallway and bathroom that will have heavy foot traffic..
I am having a really tough time getting the glue up. *It's yellow in color.
I tried Maurtic acid, brute force, heat guns, with tile scrappers, sanding,
steel brushes. *The only way I can soften it up a bit is steam from a
wallpaper steamer and scrape but it needs several minutes of steam and then
it only gets some of the glue up.

The new floor is a floating vinyl tile floor (15 1/2" tiles) called Dura
Ceram. *it has a powered limestone base and textured vinyl coating.

How smooth does this floor have to be for the floating vinyl. *I can't get
all the glue up and I have to re-epoxy or recoat the floor. *Can I leave the
glue in place, smooth out any trowel marks and ridges as best I can and also
can I even re-epoxy over this glue or does all this glue have to come up.

Thanks for the pointers!

Any uneveness will eventually telescope thru the vinyl, especially if
it is heavy traffic.

How about using a drum-shaoed sander like those used to refinish wood
floors, with a heavy grit, to bring all the glue down to a smooth
surface?
