Installing wallpaper

  1. 1. Furniture Finishing Installing Wallpaper INSTALLING WALLPAPER TOOLS FOR WALL COVERING • A large surface (table or flat door) • Stepladder/step stool • Razor blade holder or snap blade and scissors • Plumb bob (or make your own with a string, tack and weight such as a scissors and chalk) • Smoothing brush to smooth paper • Wide metal puffy knife • Wall covering seam roller • Wall covering water tray (prepasted only) • Screwdriver for removing switch plates and outlet covers • Sponge, bucket and cleanup cloths • Drop cloth • Sandpaper and wallpaper sizing 1. PREPARING WALLS Fill any holes or cracks with spackling compound. Let dry, sand, smooth and prime. Remove any previous wallpaper or vinyl wall covering. Clean walls so they are free of foreign substances. Thoroughly cure new plaster walls and seam-tape and prime new drywall. Sand glossy walls until dull. All walls should be sized. 2. A STRAIGHT START Establish a true vertical line from ceiling to floor before hanging the first strip. Start the project in an inconspicuous spot such as behind a door, in a corner or next to a window. At this spot, measure out the width of the wall covering minus 1/2" and tack a plumb bob at the ceiling line (Figure A). When the plumb bob stops swaying, lightly mark the wall with a pencil about 2" above the baseboard. Hold string taut against the baseboard mark and give it a quick snap to mark a true vertical on the wall. Use the chalk line as a guide for positioning the first wall covering strip, wrapping the strip into the corner and 1/2" onto the adjoining wall. Strike a new plumb line before you start each new wall. 3. CUT AND MATCH Measure wall height in several spots. Take the highest number and add 4' for trimming at ceiling and baseboard. Cut each wall covering strip this length after matching the pattern. If the wallcovering has a pronounced pattern, plan to have an entire motif below the final trimmed top edge for the most pleasing effect. Roll Wisdom Management Services (M) Sdn. Bhd. 1

PREPARING PREPASTED WALL COVERING Most wall covering comes prepasted and is easily installed. Loosely re-roll strips pattern side in, adhesive side out. Start at the bottom of the strip so the top (which goes at the ceiling) is the outer flap (Figure B). Fill a wall covering water tray with the rolls for timing. Lay a weighted object such as a screw driver inside the roll to keep it immersed. Change water often to prevent adhesive build- up on the wall covering face. 5. FOLDING THE WALL COVERING Remove strip from water tray, unwinding it slowly, loosely fold the strip pasted sides together without creasing (Figure C). Follow the directions included in the rolls for adhesive setup time (Usually 3 minutes). PREPARING UNPASTED WALL COVERING Roll out wall covering strip, pattern side down. Apply adhesive to top half of strip with a wide brush or roller, working from end to center. Repeat this procedure with the bottom half. Follow adhesive instructions for setup time. 6. HANGING THE STRIPS Unfold top half of strip and apply to the wall leaving a 2" overlap at the ceiling. Stroke the wall covering with smoothing brush from the center toward the edges until all wrinkles and air bubbles are removed (Figure D). Unfold lower half and repeat smoothing procedure. If wrinkles occur, pull strip away from wall and rehang. 7. TRIMMING TOP AND BOTTOM Trim strip at ceiling and baseboard with a razor or snap blade knife and putty knife. Hold the putty knife against the ceiling or trim and cut with the razor knife along the top of the putty knife (Figure E). Change knife blades often for best results. Reposition (do not drag) putty knife and slide blade along without lifting for a clean, even cut. Wisdom Management Services (M) Sdn. Bhd. 2

Hang new strip of wallcovering the same way as the previous one, carefully matching patterns at seam. Use edge of previous strip as a vertical guide (Figure F).Allow wallcovering adhesive to set a minute, then if necessary roll the seam edges with a roller to ensure adhesion and a tight seam. Wipe excess glue from the wallcovering surface with a damp cloth or sponge as you go (Figure G). 9. ROUNDING CORNERS For inside corners, measure from edge of last strip to corner (at ceiling, middle and baseboard). Add 1/2" to the widest measurement and cut the next strip to this width. Save the remainder. Hang the strip turning the corner 1/2" onto the adjoining wall. Establish a plumb line on the new wall for hanging the remaining part of the strip. Hang the remainder, overlapping the 1/2" from the previous strip into the corner. For outside corners, follow the same technique of measuring, cutting and wrapping inside corners. Slit excess at the ceiling and baseboard to smoothly make the turn around the corner. Strike a new plumb on the adjoining wall to hang remainder of the strip. 10. DOORS & WINDOWS Hang a strip over the door or window from ceiling to the floor. Measure and cut excess with scissors. Cut diagonally at corner, fit, and smooth. Smooth the rest of the strip up to the edge of the molding. Finish by carefully cutting along the molding edge with snap blade or razor using a putty knife as the guide. 11. OUTLETS & SWITCH PLATES Make sure all electricity is turned off, then remove outlet cover, hang wallcovering and diagonally cut at the opening, then replace outlet cover. 12.HANGING A BORDER For prepasted borders going over a painted surface, cut border the wall length plus 1/2". wet border. Accordion-fold loosely, paste to paste, avoiding creasing (Figure H). Apply to wall. Overlap at corners as indicated for full strips. To frame a window or doorway, butt or miter corners. To miter, overlap border at a 90 degree angle and cut from outside edge to inside edge at 45 degrees. Remove excess wall covering and butt the 45 degree edges together to form a right angle of the border. When applying a border over wall covering, use a vinyl-to-vinyl adhesive.

Work crosswise rather than lengthwise, since shorter strips are easier to handle. Enlist the aid of a friend to help smooth strips onto the ceiling. Use a broom or mop to get the wall covering up (Figure I). Once there, you can slide it into proper position and smooth with a wall covering brush (Figure J). HELPFUL HINTS • Buy an extra roll of wall covering to keep in case an area is ever damaged. • Unwanted bubbles are easily removed by cutting an "X" into the bubble and carefully lifting the edge. Apply paste and press back into place. • Note dye lot number, pattern number and collection name for future reference. • Do not use newspaper to cover your work table. Ink from paper may stain wall covering. Take along scraps of wall covering to coordinate colors and patterns when shopping for other furnishings. Wisdom Management Services (M) Sdn. Bhd. 4
