   Thor,
   just a side point. Here in Australia the subbies often use wax crayon to mark points on the floor. We have since banned them from doing so as we found in cases where we later lay vinyl flooring down the markings come through the vinyl!! Maybe its some reaction with the glue?
   Regards
   Mark

   regarding new sheet vinyl over concrete floor, my local flooring shop told me that their installers just glue to concrete without any other prep.,I have a small job to do using the 'inner flex' type vinyl where you glue around the perimeter. Are they giving me bad info or what? Anyone with practical experience with this animal...help please!

   *I used the innerflex type of flooring about 7 years ago without a problem. Be cautious about the glue. I put mine over existing vinyl floor. Only thing may be that since it's not glued down entirely, there may be a feeling of walking over a drum, but this is only because I look at it with a magnifying glass. Hope this helps.

   Thanks for all the input. To clarify my concern:
   The joint between new and old concrete is never as good as when the floor was poured as one piece. Vinyl will show just about anything that is under it (incompletely filled screw holes, small debris particles, etc.). I also was concerned about the moisture left in the patched area. I liked Mike's idea of the self leveler. In the past, installers HAVE glued down vinyl to concrete floors with no problems. Those floors were single pour, completely cured concrete. This project was different--not uncommon--but not one I had done before. Thanks again for the ideas. Thor

   Leveling material is the best way to go. be carefull and feather it out (similar to how sheetrock joints are mudded). the main problem is moisture. you have no idea how the concrete floor was constructed. is there a vapor barrier, are there subdrains, etc. in these cases, always do a calicum chloride test to measure water vapor transmission through the floor. If it exceeds 5 pounds per day there are special glues you can use. if it exceeds 8 pounds per day -walk away from the job. (the water will eventually delaminate the glue and discolor the vinyl).

   Have just cut out channels in customer's basement floor for DWV in new bathroom. Customer now wants sheet vinyl. Concerned with the filled channels (concrete) telegraphing through the vinyl. Armstrong says to prime, skim coat and glue down vinyl. Anyone used any type of underlayment? 1/4" Wonderboard maybe? Held down with??? Concerned about the moisture in the green concrete. Anyone with long term experience in basement vinyl? I prefer no comebacks. Thanks. Thor

   *If you have no moisture problem from the walls or ground, you can use a self leveling underlayment. Just pour it on and go away. It will do the rest. Follow the directions an you should be just fine.
