Klyf,
Thank you for being so generous with your knowledge and experience. One last
question: I've come across a product called HydroStrip 502, retailed via
Glidden/Devoe Paints. It's a non-Methylene Chloride paint stripper for
concrete that 's completely biodegradable. (The company is Napier Int'l,
1-800-663-9274, in case this interests you). It's also $32 a gallon, and I'm
looking at about 20 gal., but if it does the job without grinding dust all
over...??? What do you think?

Naomi,
Sorry for the delay I have been out of town a couple of days.
I am not familiar with this particular product, but I have never found a
stripper I liked. They all leave a residue of some sort, and most will
drive components of the paint and themselve into the poors of the
concrete. Another problem is that the floor was probably not prepped
properly the first time.
When concrete cures, various byproducts rise to the surface. Called
laitance (after the French for milk, I assume) this material is not
bonded to the concrete and it is not easily removed either. If it is not
removed before coating, your flooring is bonded to this layer of
laitance that is not bonded to the concrete. This usually makes itself
evident in bubbles or flaking of the paint or whatever.
Using a stirpping compound will not remove this layer either.
The only approved methods for preparing concrete for a coating are
sanding/grinding, shot blasting or acid etch/pressure wash.
As we say in my industry; it's all in the prep work.
Good luck with your project

Klyf,
Wish I lived in New Mexico--then you could do the floor! Thank you for
taking the time to explain everything. I haven't yet decided which approach
to take, but soon will.
Wishing you a happy holiday and new year!
Naomi
