I had a porcelain tile crack in the kitchen. In the process of removing the tile, another popped.

Now I have 2 tiles I need to put back. The back of the tiles are both free of any mortar.

My question is regarding putting the 2 tiles back in. I have the new premixed mortar I purchased. Do I need to scrape any more old mortar off the subfloor?
This is what it currently looks like:

Is there anything else I can do to ensure the tile doesn't pop up?

You don't say if you have scraped the floor. Scrap the concrete good
and vacuum any dust off.

YMMV

Should read wood, not concrete. sigh

I did scrape to the wood. As you can see by the photos, there is a layer of mortar dust on the wood. I'm curious if I need to see all wood in those photos, or if a dusting of mortar is ok. My concern is if i scrape to the wood i might cut into the subfloor. I already nicked it twice in small sports.

The base needs to be flat enough so the tiles you are setting wind up at the
same height as their neighbors.

Make sure the mastic covers all the tile and that when it squeezes into the
indentations of the tile that sufficient remains to completely cover what
you are sticking it too. Grout after several days and don't walk on it
while you wait.

The first thing you need to do is determine how many tiles are loose,
Sounds like the adhesive used has failed/is unsuitable.
This is why they are cracking.
You may have to take them all up.
And yes, you will need to chip off some of the old adheasive to make
space for the new.

If the premixed mortar is something like this:

http://www.homedepot.com/buy/35-gal-...ar-sttsw3.html

you may want to consider taking it back (if you haven't opened it yet) and
getting regular thin set mix and mix it yourself. The reason is that,
according to the reviews that I see here, there can be issues with the stuff
taking forever to set up and dry.

Since you scraped the old mortar almost down to the wood, I think that will
be good enough. But, I also think there are bonding agents that can be
painted onto the subfloor first to help with adhesion. I forget what they
are called, but whatever they have for that will be in the tile section
where you bought the premixed mortar.

Personally, if I had what you have and didn't open it yet, I'd return it and
just do the job with regular (mix-it-yourself) thin set. Or, if I did
already open the container, I would just use it and do the job as-is and
expect it to take a few days to dry. In either case, I don't think I would
worry about the small amount of old mortar that is still left on the wood
subfloor.

Good luck.

Not good. Those probably aren't the only tiles that will pop.

No, that looks pretty good. Just make sure you vacuum any loose material up.

I don't like the idea of premixed mortar (it isn't). If it were really mortar
I'd moisten the tile and the floor before spreading it. The premixed stuff is
probably a vinyl mastic so I'd just follow the directions on the packaging.
You might look the stuff up online and get further information.

Well yes, unless you want the 2 tiles to stick up highr than the rest
of the floor DUH!

....another thought I had was for the OP to inspect to sub floor. If
the floor has *some weakness* like flex or spring the OP can add some
screws into the flooring to tighten it up.

Wood sub floors can allow the tiles to pop up again when not secured
down very well,

Good point. I always put 1/2" backer down with a jillion screws and mortar
before the tile but it's a little late for that here. ;-)

The floor looked pretty clean to me.

In a second floor bath I used backer and a box of screws. Second story
wood floors need it. OP can use some screws in what he has....in the
joist to stiffen it up,

Did he leave the thread?

I think Bob misread that sentence as:
