Today I stripped off this paper. It was dark and dated. But also, it had started curling up a bit at the seams.
The homeowners said this started after Hurricane Harvey, when they were without power for two weeks, and the lack of air conditioning allowed humidity to permeate the house.
So here we have paper-backed, pre-pasted, solid-vinyl wallpaper doing what it does best – succumbing to humidity, by allowing moisture to wick in behind the seams, which causes the paper backing to swell, pushing the vinyl surface back in a curl. Sometimes, the paper backing actually delaminates (comes apart from) the vinyl layer.
My main reason why I encourage people to steer away from these materials. The price point is attractive, but the quality and longevity is not.
Interestingly as a side note, it looks like the previous installer did not pay attention to the pattern match. Well, no biggie. On this design, it is not very noticeable, and the homeowners have lived with it happily for 20 years or more.
