You should always use two people when wallpapering the ceiling. Make sure you use heavy duty adhesive and give yourself plenty of time to complete the job. If you are using the same paper on the walls, paper the ceiling first and make sure to match the seams from ceiling to walls.

Step1: PRIME AND PATCH THE CEILING

Lay out the paper on the ceiling so that the strips will overlap the wall by about ½ inch. When you lay out the strip, hold a roll of paper against the ceiling at one side of the room. Now, mark on the ceiling ½ inch from the end of the roll. Go the the other side and make a similar mark.

Step2: SNAP A CHALK LINE CONNECTING THE TWO MARKS.

You will want to use blue chalk because red chalk will bleed through the paper. Cut a strip of paper to the exact length and then apply wallpaper paste activator.

Step3: WORKING IN SMALL SECTIONS, POSITION THE STRIP AGAINST THE GUIDELINE

Make sure you overlap the side wall by ½ inch and the end walls by 2 inches. Take a smooth brush and flatten the strip as you work. If you are going to cover the walls with the same paper, trim the ceiling wallpaper so it overlaps the wall by ½ inch. If you are not covering the walls then trim the excess by holding a broad knife against the corner and cutting with a razor knife.

Step4: CUT OUT A SMALL WEDGE OF WALLPAPER IN THE CORNER SO THAT THE STRIP WILL LIE SMOOTH.

Press the wallpaper into the corner with a broad knife.
