Hi all,
We're just about to start a small tile job (<45 sq ft bathroom). Last night
we tore up the ugly vinyl tile floor. It came up pretty easy with a heat
gun. The concrete slab underneath is in great condtion, but is noticably
"tacky" from the vinyl tile adhesive. We're not talking globs of adhesive
or anything, in fact it isn't really visible at all, except for a little bit
of gloss here an there and some other discoloration of the concrete. But
nothing like big black or yellow/gold blobs of adhesive like I've seen
elsewhere.
So my question -- will my thinset stick to this, or should I attempt some
sort of chemical strip? We used some household cleaner (409) and a wire
brush, then mopped with a strong floor-cleaner solution, and that helped a
little, but it's still quite tacky when you feel it or walk on it.
I'm guessing the original floor is circa mid-80's if that matters.
Thanks much for your help -- I'd apprecate any replies as we hope to do some
work on it yet tonight.
-Tim

To get rid of the residual sticky stuff, I'd use some low-impact
petroleum solvent: either paint thinner (*not* remover) or charcoal
lighter (naphtha). These are relatively benign, will probably dissolve
some, but not all, of the sticky stuff, and can be removed with any kind
of soap or detergent. (You can use low-odor paint thinner if you're
concerned about the smell.)
After that, if any stickiness remains, try using denatured alcohol
(shellac thinner) the same way. I've found that it sometimes takes a
combined attack of naphtha and alcohol to get rid of certain sticky
substances. As above, wash the alcohol afterwards, though most of it
will just disappear through evaporation.

Charcoal starter is kerosene.
Naphtha is much lighter. Coleman fuel. Definitely not for charcoal.

Nope, you're wrong: I also stock kerosene (have 2 portable heaters that
use it), and that's a completely different "product". Easily
recognizable by smell alone.
Both charcoal starter and lighter fluid (e.g., Ronsonol) are naphtha,
which is a lighter fraction than kerosene (paraffin for our UK friends).
You're thinking of "white gas" for Coleman fuel. I'd definitely stay
away from that stuff!

Amending my post: boy, this is one confusing area, especially if you try
to get information on the web. A lot of this information seems to be
plain wrong.
So apparently, ordinary charcoal lighter *is* a mixture of naphtha and
kerosene. However, the charcoal lighter I use (mainly to clean stuff)
seems almost identical to pure naphtha, and evaporates at about the same
rate. Kerosene evaporates much more slowly, and leaves an oily residue
behind.
But it isn't the same thing as white gas, of that I'm sure, even though
there are plenty of sites out there that say that white gas = naphtha.
For one thing, white gas has a *much* more pungent odor than naphtha,
and evaporates much more quickly. I did find one site that seems to have
a good definition of white gas:
http://www.everything2.com/index.pl?node_id=776626. It is similar to
gasoline.
Lighter fluid ("Ronsonol") *is* naphtha, so far as I've been able to
determine.
