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.

Humidity in Bathrooms – Not Good for Lower-End Solid Vinyl Wallpapers

June 7, 2019

People often think that vinyl wallpaper will be good in a bathroom, because water will roll off it. but in reality, very little water gets splashed on the walls – but a lot of moisture can get wicked into the seams.

These photos (you may want to scroll to enlarge them) show how the lower-end, paper-backed, solid-vinyl wallpapers tend to perform poorly in humid rooms like bathrooms. The problem is that moisture gets in between the seams and into the paper backing. That backing absorbs moisture and expands, curling away from the wall. The backing can actually go a step further and delaminate from the top vinyl layer.

This type of paper often performs like this when you’ve got people taking steamy showers, forgetting to turn on the vent fan, forgetting to keep the door open for air circulation, etc. Neither of these situations can be fixed. You will be stuck with these slightly curled seams.

The thing is, there are plenty of nice, paper or non-woven wallpapers out there, that will hold up a lot better in bathrooms.

Humidity in Bathrooms – Not Good for Metal Light Fixtures

June 7, 2019


This is the same bathroom that showed the curling / delaminating wallpaper seams, probably caused by humidity.

This photo is of the base of an over-the-mirror light fixture. See the little dots? I believe these are specs of rust starting to work their way out through the finish. Most likely also caused by humidity.

Keep heat and A/C systems running, limit steamy showers, keep the exhaust fans on, and keep doors open!
