Weird Bubbles Develop on Wall

January 21, 2021

This wall had a slight texture that needed to be skim-floated and then sanded smooth. After I applied the smoothing compound (drywall joint compound), a half hour or so later, these tiny blister bubbles appeared. This is off-gassing. But from what is a mystery.

The only clue is that this area is around where the hand towel was positioned next to the sink. So this area would have received a lot of splashing of water and also soap and other toiletries.

My guess is that some of these substances stuck to the wall. And for whatever reason, when they were covered by the joint compound, they released air / gas, which caused these bubbles.

I’ve seen this before. But this time, some of the bubbles were large enough that they did not sand down smooth and even with the wall surface. So I had to do a light touch-up skim-coat on top.

Once I got the wall smoothed, I wasn’t too concerned. I don’t believe that anything causing these tiny blisters would be something that would bleed through and stain the wallpaper.

Some substances do stain wallpaper, though. For more on that, do a Search here.

Don’t Let Water / Toiletries Splash On The Wallpaper

January 20, 2021

Very hard to see here, but look closely and you will see vertical stains running down the wall.

This wall is right behind the sink. And this spot is right below the hand towel. Obviously, people reaching for the towel with wet hands has led to water – sometimes tainted with soap, toiletries, or cleaning agents – to drip down the wall.

The resulting stains are minor on the painted wall. But, once the wallpaper goes up, it is possible that these substances will bleed through the primer and the wallpaper and cause staining on the new wallpaper. So, proper remediation is needed to prevent stains from bleeding through.

Also, once the new paper is up, people will need to be more cognisant of not splashing the wall.

It’s a misconception that wallpaper is “washable” or “stain resistant” or “will hide flaws.”

Best to treat your new wallpaper with care.
