Choose the right primer for the job
If yous're dealing with older wallpaper, then it was most likely pasted to the wall over a chemical compound chosen sizing, which helped protect plaster walls from the moisture of an agglutinative. "If you go to paint it, that glue tin stain your pigment if you don't seal it," Snyder says, "so you lot take to utilize an oil-based or shellac-based primer first before y'all pigment over it."
You'll want to utilise an oil-based primer over the wallpaper before y'all paint. Oil-based primers tin take longer to dry out and the olfactory property will be overbearing, but there are at present some fast drying options available. "Oil-based primer will block anything coming through," Snyder says. "Whether there are patterns on the wallpaper or the glue behind the wallpaper, it will block that so you can paint correct over that." Cheque the instructions on your oil-based primer to make certain information technology's uniform with water-based latex paints.
While oil-based primers tin exist great, Snyder says the strong smell is worth noting, and when possible, he prefers to use B-I-N shellac-based primer instead. The smell dissipates faster and it dries in 15 to 30 minutes (and it tends to dampen any bubbles out of the wallpaper because it sucks the moisture out). You'll exist able to employ latex pigment over this primer.
When using oil-based primer, have mineral spirits on hand to clean upward whatever spills or outside-the-lines moments, as well every bit your brushes afterward. If you're going to use an booze or shellac-based product, accept denatured alcohol on hand to make clean up.
Snyder says it's of import to use quality products, and recommends Purdy or Corona brand brushes, and roller covers in a ⅜-inch-thick size. "Don't get cheap on brushes and roller covers!" he says. "Better brushes and covers mean better coverage and application."
Prep your space
Clean your walls with a damp (not wet!) rag to remove any dust or dirt that might have collected on your wallpaper. Tape off the wall trim to protect information technology from the primer. It's all-time to move as much of the furniture out out of the room as possible; whatever yous can't move, make sure to cover.
Repair any obvious problem spots
Are parts of the wallpaper peeling off or are the seams popping upwardly in spots? Snyder says to take a sheetrock knife, cut off the loose piece, then use a brush to pigment the B-I-North primer over the spot to seal it off. For seams that might be curling upward, he recommends cutting off the part that'south curling and sealing it with B-I-N, as well.
"Whatever exposed areas, seal it with B-I-N commencement, then yous can use spackling compound over it once information technology's dry," Snyder says. If you take textured wallpaper, he recommends using an orbital or palm sander with 150-180 grit sandpaper to smooth downwardly the surface to an fifty-fifty level.

"Oil-based primers and B-I-Northward primers can be kind of splashy," says Snyder. "Become tedious at first. Less is more. Apply a little scrap until you get used to the feel of information technology."
Once your primer has dried, reinspect to meet if there are any rough spots in the wall. If you need to go dorsum to gear up something at this indicate, Snyder recommends using 3M Patch Plus Primer spackling compound, considering it already contains primer in it—that mode, you won't have to re-prime number the entire wall. If yous take your time and are using quality products, one glaze of primer should do.
