Getting ready to redecorate? Is wallpaper installation part of that project? If so, here are some helpful do-it-yourself hints for those of you daring enough to take on the task.
First be sure the walls are clean and mildew-free. To be sure, scrub the walls with a mixture of household bleach and water - 50 percent of each. Using a soft brush, scrub until all dirt and mildew (if any) are gone. Let the walls dry at least overnight to be sure they're completely dry before applying the paper.Next, apply a primer sealer or oil-based paint to provide a smooth and sealed surface onto which the adhesive, then paper will stick easily, yet be just as easily removed in the future without damaging the wall. If the paper is not prepasted, apply wall sizing next.
Before actually applying the paper to the wall, inspect it to be sure it's not damaged and has no flaws. If the paper is prepasted, fill a water tray about two-thirds full of lukewarm water and set the tray at the end of the work table or on a surface near the work table.
After measuring the wall, cut several strips to the desired length matching the second strip pattern to the first, the third to the second and so forth. To keep your sanity, number the back of each strip. Starting with the first strip, roll from bottom to top with the pattern inside. Immerse in tray with water for the amount of time indicated on the instructions that came with the paper - usually 30-45 seconds. Carefully remove the strip from the tray and place on the work table, pattern side down.
Fold the paper in half, paste to paste, but do not crease it. As per the instructions again, let this stand for a while - usually 3 to 5 minutes. This is an important step in hanging prepasted papers, so don't skip this process.
Now it's time to place the paper on the wall. Smooth it on with a soft brush, and be sure to get all the bubbles out. A damp cloth may be used also to wipe the adhesive that might seep out the sides. Apply the next strip in the same manner, then roll the seams with a seam roller to secure them.
If the paper isn't prepasted, spread an even coat of adhesive on the first strip, fold in half, paste side to paste side again and remember not to crease it. Put the paper on the wall and smooth it out just like the prepasted paper. Get the bubbles out and roll the seams.
For both types of application, be sure to clean the rinse water often.
If there's a border to be installed, it can be applied over the wallpaper. It's suggested that a special vinyl-to-vinyl adhesive be applied to the border instead of the paper to wall solvent. It's not recommended, however, to apply new wallpaper over old wallpaper. It just doesn't work well.
