Follow adhesive instructions for setup time. Unfold lower half and repeat smoothing procedure. If wrinkles occur, pull strip away from wall and rehang. Trim strip at ceiling and baseboard with a razor or snap blade knife and putty knife. Change knife blades often for best results.
Fit strip edges together without any overlap or gap.
Hang new strip of wallcovering the same way as the previous one, carefully matching patterns at seam. Allow wallcovering adhesive to set a minute, then if necessary roll the seam edges with a roller to ensure adhesion and a tight seam. Save the remainder. Establish a plumb line on the new wall for hanging the remaining part of the strip. For outside corners, follow the same technique of measuring, cutting and wrapping inside corners.
