Fold the strips in half in the crosswise direction so the vinyl backing is visible. Apply the adhesive to the subfloor with an adhesive comb. Lay the floor covering back onto the adhesive. Now fold over the other half of the strips and apply adhesive to the subfloor. Lay the floor covering on the adhesive. The whole subfloor is now covered with adhesive. Lay the strips straight and tightly against each other in the adhesive. For a good bond, press the floor covering down firmly over the whole surface with a carpet roller. When the seams are pressed against each other properly, they will no longer be visible. If the length seam buckles, you can correct this with a knee kicker.
