If you have a complex shape to cut, you might want to make a paper template first. You can trim a little with the scissors if you need to. Be sure the piece fits before peeling off the backing. When placing the cut tile, make sure to turn it around, so the factory edge butts up against the edge on the next tile. It was easier and less dangerous for me to use than a utility knife, and I found it more accurate. Use a straight edge to draw a cutting line. When cutting the edges around cabinets, with the paper backing still on, hold the tile snugly up against the cabinet and mark where to cut at both edges with a sharpie. Fill in the center of the floor, placing all the tiles that don't need to be cut first. Once you have your tile in position, press it down firmly, making sure to squeeze out any air from underneath it and paying special attention to the edges. If you make a mistake with sticking a tile down, you can reposition it by peeling it up if you do it immediately. Lay your first line of tiles carefully right along that straight line then you can build off of those tiles aligning each one carefully. I measured three feet out from the existing living room floor on each side of the doorway, and that's where I snapped my chalk line. If you have a chalk snap line, that is ideal, if not you need something long with a straight edge so you can mark a straight line to build off of. Don't try to use the edge of a wall or cabinet they may not be perfectly straight or square. You need to mark a nice straight line toward the center of the floor to use as a guide. I started from the doorway, thinking I didn't want to have cut tiles in that very visible spot. The next thing you have to do is figure out how you're going to want to lay out the tiles.I was able to scrape it up with a putty knife and was left with a nice clean surface. It bonded with the old adhesive and it was no longer sticky. I just sprinkled it on and used a broom to spread it around. Finally, I saw a suggestion about using corn starch. I was afraid to use anything oily for fear it would interfere with my new tiles sticking down. I tried soapy water and wall paper paste remover, but they were not much help.
I tried to scrape it off, but it was very sticky. On another floor I did, there was old adhesive on the floor that had to be removed before I put down my new tiles. I had one fairly large hole I patched with it, and it was dry enough to tile over in 24 hours (I actually was not able to contain myself for that long, and I tiled around it until it was dry enough). You just make a thick paste with it and smooth it into the hole. It works on wood, concrete, or just about any surface. You can use a product like Fixall if you have holes or gaps to fill.Any nail heads sticking up will work their way through the vinyl, so either pull them out or make sure they're pounded in really well.I can't stress enough the importance of this step. If there are any bumps or holes in the floor, you need to get them as smooth as you can.You'll need to get the floor as clean as you can and let it dry.
