Should you remove wallpaper or paint over it?

Why painting over wallpaper usually backfires

Wallpaper is a separate layer stuck to the wall with water-soluble paste. Paint on top of it is only as good as that paste, and latex paint is mostly water. The problems tend to show up in the first week or the first humid summer:

• Seams show through the paint as straight vertical lines, especially in side light, and often get worse as the paper shrinks and swells
• Water in the paint softens the paste and the paper bubbles or lifts — sometimes right away, sometimes in patches later
• Edges and corners that were already loose peel back, taking the new paint with them
• Vinyl and coated papers have a slick surface that paint does not grip well without a bonding primer
• The pattern or texture of the paper can show through the paint
• When someone does take it off later, painted paper resists water and steam, so removal is slower and harder on the wall

When painting over wallpaper can work

There are cases where it is the reasonable choice: a single layer of paper that is stuck down tight across the whole wall, with flat seams and no loose edges, on a wall where removal would clearly do more damage than it is worth.

If you go that way, glue down any loose edges, skim the seams so they do not telegraph, and seal the entire surface with an oil-based or shellac-based primer. A solvent-based primer does not re-wet the paste the way a water-based one can. Then paint with latex as normal. Accept that it is a cover, not a fix, and that whoever removes it later will be dealing with a harder job.

How to tell what kind of wallpaper you have

Lift a corner with a putty knife at a seam, ideally somewhere behind furniture, and pull slowly. How the paper behaves in that first minute tells you most of what you need to know about how the rest of the wall will go.

• Strippable: the whole sheet comes off in one piece, leaving little behind. The easy case.
• Peelable: the top layer comes off and leaves a thin paper backing on the wall, which then needs soaking and scraping.
• Traditional paper: it tears in small pieces and has to be soaked and scraped off the whole way.
• Painted paper: water beads on it and nothing soaks in, which means the surface must be scored or the paint broken before it will release.
• Several layers: older houses often have two or three papers stacked up, sometimes with paint between them.

How wallpaper removal works

The method is always the same idea: get water through the face of the paper to the paste, let it soften, then scrape it off with a wide knife at a low angle so the blade does not dig into the wall. Turn off power to outlets and switches on that wall and remove the cover plates before anything wet goes near them.

After the paper is off, the paste residue has to be washed off the wall completely. Paste left behind can make new paint crack in a crazed, alligator pattern, so this step matters as much as the stripping.

How long wallpaper removal takes

Longer than most people expect, and it is the hardest part of the job to predict. A strippable paper on primed drywall can come down in an afternoon. A painted paper, a vinyl hung with heavy adhesive, or three layers in an old plaster room can take days for the same wall area, with drying time before any repair or primer can start.

Bathrooms and kitchens are often the slow rooms. Paper there was frequently hung with stronger adhesives to resist moisture, there are more fixtures and cabinets to work around, and the paper is cut into many small pieces. Borders at the top of a wall can be on top of paint, on top of other paper, or both.

When the wall underneath is damaged

Paper hung straight onto drywall that was never primed or sized can bond to the drywall’s own paper face, and taking it off pulls that face up in brown, fuzzy patches. That is the most common damage, and it is fixable — but not by painting straight over it.

Torn drywall paper has to be sealed with an oil-based or shellac-based primer before anything water-based touches it. If joint compound or latex paint goes straight on, the paper soaks it up, swells and bubbles. Once it is sealed, the wall is skim coated: a thin coat or two of joint compound over the whole surface, sanded smooth, then primed and painted.

Skim coating also covers gouges from scrapers, old adhesive ridges and uneven patches, and it is often what makes a stripped wall look like a new one. It adds time and is worth having on the estimate as its own line.

Tip: Shine a work light along the wall at a low angle after stripping. It shows every gouge and torn spot that will need attention before primer.

Older plaster walls around Worcester

In Worcester, the median home was built in 1951, and many houses in and around the city still have their original plaster walls. Plaster usually handles soaking and steaming better than drywall because it has no paper face to tear. The risks are different: multiple layers of paper, paper that was hung to hide cracks, and old plaster that has let go of its lath in spots, which can sag or come away when the paper over it is removed.

There is also what is under the paper. In houses built before 1978, older paint layers may contain lead. Wet scraping keeps dust down, but sanding or dry-scraping painted surfaces in an older house is the point to stop and use lead-safe work practices. If you hire the work, ask the contractor about their lead-safe renovation credentials under the Massachusetts program.

What to ask a painter about wallpaper removal

Nobody can promise how wallpaper will come off until a corner has been tested, so a good estimate is honest about the unknowns. Ask how they will remove it, whether the price covers washing off the paste, what happens if the drywall paper tears, and whether skim coating and priming are included or priced separately. With those answers on paper, the surprise is in the wall, not the bill.

If the paper is in a room you live in daily, ask too how the work will be scheduled around drying time. A stripped, washed wall needs to be fully dry before it is sealed and skimmed, and a skim coat needs to dry before primer, so the room is out of use for longer than the painting alone would take.
