My client wants ceramic or porcelain tile on her back porch. The
previous owner had glue-down green carpet/fake grass there. My question
is: Can I put thinset down on top of the remaining skim layer of carpet
glue?

An Internet search gives me advice all over the map: remove it with
solvents/don't use solvents because they soak into the concrete and
keep thinset from sticking; remove it with abrasives/don't because it
just melts and wastes time; remove and replace an obscenely thick layer
(1/4 - 1/2 inch) of concrete.

* The surface is smooth and even, and it is sloped properly.
* I power-washed it awhile back, and the glue washed off just slightly.
* I plan on scraping with a 4" razor in any case.

The fact that the glue dissolved slightly makes me hopeful that
water-based bedding material will "bond" with it. On the other hand, it
makes me worry, also, that it won't.

I'll take any advice I can get.

Hey Steve:

Need to get out of the remove it box thinking..

You know well enough that tile needs a good solid base. Maybe it's
already cement with the glue on it?

Sounds like you need to get some cement board of the proper thickness
down in any way you can. Then you know the tile will stick to a brand
new surface designed for tile.

Maybe whatever your situation is cement board is out of the question?

Rueful Chuckle. Idiot previous owner put that crap down in the furnace
room here, along with cheesy 1960s wood paneling and a drop ceiling
screwed to the ducts. It was apparently his gun room, including the
reloading equipment. (Here's yer sign, etc.)

Anyway, I had to do a lot of demo in there to make a road for the crew
replacing the furnace, and I still haven't got all that black carpet
residue off the the floor. I scrape and sweep and vacum, but there
always seems to be more. A couple hundred bucks of industrial floor
matting (the interlocking squares) is starting to look real tempting.

Customer had that on an outside patio that he decided he wanted tiled. Get
as much up as possible and scrap with a heavy duty scraper. I got most of
it up I also used some solvent made for that purpose. Just use a good thin
set for concrete and it should be fine. I did this job 4 years ago and it
seems to be holding up fine.

Try a propane torch to burn it off then power wash.

IF it isn't perfectly smooth, you'll have problems with ceramic tile.

Caution advised with a torch on concrete. Old time welders know that
concrete exposed to sudden heat will explode. Let the torch warm it up
at a little distance, Whatever, good luck.

Try a small patch, like maybe glue down one tile, and see how it
goes?

If it is water based, I would try a scrubber/buffer, the big ole fashioned
kind that is used for comerical floors, for buffing and stripping wax, my
local home depot rents them, get some of the corsest pads they have, and
some simple green and water, put some down and start scrubbing, I have had
the guy at the rental store in home depot tell me people use them to clean
off slabs in prep for tile and other floors to go down to the slab, and I
think running a big buffer is pretty fun also.
stay away from the high speed models, they are used to buff out the wax, but
buffer is a generic term for most of them.
Good luck

This sounds like it would work. Thanks for the suggestion.

I power-washed the surface thoroughly yesterday, and that got off all
the loose stuff. I asked about this issue when I ordered the tile
today, and the tile-store guy called the manufacturer for me. They say
their thinset will stick just fine, as long as I put down a complete
layer.

Huh. Who doesn't put down a complete layer?

I have some RedGard left in the garage, so I'm thinking of donating it
to this project to seal the glue. The tile-store guy said it's a good
idea, but he'd be happy to sell me his competing brand....
