Paint Pulling Off Wall Where Tape Was Removed – Surface Stability Test

It’s important to have a stable surface under wallpaper.

That’s because, when wallpaper gets wet with paste, absorbs moisture from the paste, and it expands. Then, as it dries, it lets go of the moisture and shrinks. When wallpaper dries and shrinks, it puts tension / torque on the walls.

If the surface under the wallpaper is not stable, the tension of the drying wallpaper can cause the underlying surface to pull away.

This photo is not showing the wallpaper pulling away from the wall. What is happening (usually) is that the paint (or whatever has been applied to the wall), has actually delaminated (come apart) from the wall.

This results in a “curled” seam, or a “popped” seam.

One way to test for this is to apply a strip of tape (blue painters tape, tan masking tape, clear Scotch tape, or other), let it sit a few minutes, and then yank it off. If the tape takes any paint along with it, you have a potential problem of the wallpaper not adhering correctly.

This is why it’s important to:

1, Before applying any coating, you must remove all dust from the wall, using a damp sponge, which must be rinsed frequently

2, Before hanging paper, a primer formulated specifically for wallpaper should be applied / rolled on and cut in to edges

A wallpaper-specific primer is designed to withstand the torque put on the wall as wallpaper dries. And it facilitates installation by allowing sufficient “slip” (maneuvering the paper) and “stick” (adhesion). The chemistry behind all this is fascinating – but too complicated to get into here.

If a wall is too “iffy,” and you don’t feel like the mess and expense of scraping off all the old paint, a liner can be applied before the actual wallpaper is hung.

A liner lessens the drying time of the wallpaper, which reduces the time there will be stress on the wall. A liner also redistributes stress on the wall, so much less chance of having seems detach from the wall.

A liner also adds additional cost to the job – for both material and labor, which may include an additional day(s).

Fixing the Underbidder’s Job

March 21, 2010

Wallpaper Installer in Houston

A comment to my previous post about loosing a job to a someone who underbid me, said that I may end up fixing the cheapo job. Well, that DID happen, at least once. I LOVE the story, too. Read on…

The client (once again, in a lovely near-million dollar home) had some gorgeous, hand-screened, $100+ per roll, Bradbury & Bradbury reproduction turn-of-the-century wallpaper (Google it), that had to be hand pasted and hand trimmed. Not a job for a novice.

I gave her my price, and she whined. I NEVER lower my prices (will blog on that at some point), and she whined some more, and finally went with another installation company who underbid me by FIFTY DOLLARS.

Well, it was gratifying to me, in a way, when, a week or so later, she called me and asked me to fix the other guy’s mess.

Whereas I work alone (for quality control and to reduce the impact of people tromping through the home) and planned to devote the entire day to this job, Wallpapers To go sent a crew of guys to all squeeze into the little powder room, knock out the job, and then GO ON TO A SECOND HOME to do another job that same day.

EIGHT HUNDRED DOLLARS worth of wallpaper, and they’re going to “knock it out” in one morning?! What about prep? (Didn’t do any.) What about carefully matching the pattern? (Had many mismatches.) What about the care and precision required to “double cut” (splice) the hand-trimmed paper? What about wiping excess paste off the surface? What about just paying attention, taking your time, and doing a careful, detailed job?

I can’t say their work was HORRIBLE, but it was by no means good. There was no way to make the room look great other than removing the old paper, buying more, and completely redoing the entire room, and that was out of the question. I was able to fix a few little things, and make the overall appearance much better. The client was satisfied, and realized that her $50 bargain meant she would have to live many years with the result of a “lowest bidder” job.
