Vinyl floor tiles (self-stick)?
Asbestos in flooring has been outlawed since the 70s and couldn t be sold after 79. Always best to take up the old and start fresh, but under certain conditions you can install over existing vinyl or vinyl tiles. The flooring down now must be very clean, grease free, bonded well with no loose or missing hunks. You should use a filler to go over the seams or grout lines on the tile down now. This will help prevent those seams from showing through the new tiles. You must off set the new tiles so you don t have a seam over a seam. This must be done vertically as well as horizontally.

Everything rob said. I would take it a step further and suggest that you add more adhesive to the project. In a year or two you'll have tiles popping off of the floor, from the poor quality of self sticking adhesive they use on those tiles. Take 10 minutes and look into VCT installation, drawing your square lines, etc. Go to Lowe's or something, get 1 or 2 small pales of pressure sensitive tile glue (buy extra, take one back later), a paint roller, and a cheap 3/8 nap roller cover and a cheap pole. Next step....Get your floor prepped, and swept up well, chaulk lines drawn in with pencil, find your starting point... now read the instructions on the glue(this is important), and then you can paint the floor with the glue. Not too much, not too little, but evenly. And don't make your tile starting point inaccessible after the gluing :) Glue half the room at a time if needed. This is going to keep your tiles from popping up in the future, and ALL of those self stick tiles do, IF you don't re-enforce the adhesion. (don't use a trowel to put the extra glue on, you will see the fingers of the glue through the thin tile. the paint roller keeps everything smooth) (guys like rob want you to buy a new floor every two years :) )
