RePaste and Disguise Split Wallpaper Seams

October 10, 2020


Several seams in this bathroom, as well as some whole sections of wallpaper, had come away from the wall.

Most likely, this was due to a combination of things … Number 1, extreme humidity from teenaged son taking showers with no ventilation and over several years. Number 2, possible improper wall prep before the wallpaper went up. Number 3, Unstable surface, which allowed layers inside the wall to delaminate and separate from each other.

Whatever the culprit, I had success in using wallpaper paste to re-adhere most of the loose areas back to the wall. We were still left with visible gaps at some of the seams, where the wallpaper had shrunk.

I used water-based craft paint to color these areas. I didn’t use the brushes … I just daubed my finger in the undiluted darker tan paint and swiped it over the gaps, pushing to be sure it reached to the wall. Then I wiped excess off the surface of the surrounding wallpaper with a damp rag.

I used water to dilute some of the blue and red paint, and then added that over the appropriate colored areas. I used the tiny brush to dot on bits of near-black paint, to correspond with the black printed areas on the wallpaper map.

From a distance, you could not see the touch-ups. Even better – you could not see the touch-ups even if very close.

20+ Year Old Paper – Still Perfect

July 31, 2019


I hung this paper in a master bathroom in Bellaire more than 20 years ago. It is still in perfect shape!

This is due partly to the good quality paper the homeowner chose (not low-end, pre-pasted, paper-backed, solid vinyl), to good ventilation removing humidity from the room, to good installation techniques, and to the great primer I used at that time – Oil Based KILZ Original. Unfortunately, EPA regulations forced changes to this primer, and wallpaper paste will no longer stick to it.

The homeowners are going to renovate and update the bathroom, so I was there taking measurements for the new room. When it comes time to remove this old paper, I know that it will strip off easily and cleanly, because of the installation and primer used when it was put up.

Paper-Backed Vinyl Is Not Good In A Bath

Oh, boy. I sure don’t like vinyl papers that are bonded to a paper backing. Here is a very visual reason why – Under humid conditions, they delaminate (surfaces separate) and curl.

This particular type of paper is about my absolute most detested, because of it’s propensity to curl. The material is typical of what was hung back in the ’70’s. Other issues factor in, like the type of primer used (or not used 😦 ), the paste used, type of paper backing, type of vinyl surface, age of home, ventilation in the room, and just how much steam is generated when the shower is used.

To be fair, this wallpaper had been up and looked good for a long, long time (possibly back to those ’70’s!). So maybe Father Time is just taking its toll.

And maybe Father Time has an ulterior motive … I mean, look at that paper! Isn’t it about time for a little update?!!
