Installing vinyl floor: patch & skim coat

I had an old vinyl floor in my kitchen that I've now ripped out. What's left is a particle-board type subfloor over the actual wood beams beneath.
The bottom of the old floor has stuck to the subfloor in most places, so there's a thin layer of black stuff across the entire floor, most of which is pretty sticky (I guess it's the old glue).
I'm planning to put vinyl squares down, but I went to Home Depot to figure out what to do about this sticky gunk that's left on the subfloor. The guy there recommended putting down a patch & skim coat over the entire floor, then tiling over that.
So my questions are:
1) Does this sound like the best solution? He said using a chemical to remove this junk would probably be a lot messier in the long run.
2) Any advice about how to apply the patch & skim coat? Is it pretty easy? He said just to mix it with water, apply with a trowel and then level out any high spots. How thick should I aim to make it? And, what do I do about cabinets and walls? Should I do anything to protect these edges from the patch & skim, or should I just go right up to the edges?
thanks for any feedback, Matt

Save yourself a lot of grief and either replace the junk subfloor or sheet it over. Had one like that in my kitchen, fridge water system sprung a leak and the stuff swelled up and decomposed. Hopeless situation, pulled it all out, replaced it with a good solid T & G plywood subfloor. If you use self stick tiles, the plywood needs to be leveled, coated (cheapest urethane varnish works fine), and joints filled and leveled (bondo works great). For other kinds of tile or flooring, follow manufacturers instructions. In any event, in a room with water service, junkboard is a poor choice. Good luck on your project.

I've installed a few vinyl tile floors. If your'e saying that some of the particle board was stuck to the old floor, I would vote in favor of putting down a 1/4" plywood (or Hardibacker) layer on top of the whole thing. That way you'll have a nice clean and smooth surface for your new tiles. Dealing with the old glue and voids in the floor is a real pain (not to mention you probably won't get very good adhesion to your tiles). Putting down a new surface is pretty inexpensive and won't take very long to do. Just make sure your plywood seams are even (level) with each other and don't lay a tile seam directly over your subfloor seam.
Good Luck,
Dean
