If you are using a tile system with corner, center and border tiles available for a wall to wall install, it is usually easiest to start in one corner of the room with a corner tile, line the adjacent walls with border tiles and fill in the rest of the room with center cut tiles.
When piecing interlocking tiles together, adhesives are usually not used since the weight of the locked together product is usually enough to keep the floor tiles from moving. However if you do experience some movement and would like to ensure that the tiles do not slide at all, some double sided carpet tape can be used around the perimeter of the installation to prevent any movement.
