Don’t Use Paper-Backed Solid Vinyl Wallpaper in a Bathroom

November 4, 2021

You are looking at seams in a bathroom that are curling and opening up. This is due to a combination of things.

1, Probably the walls were not prepped properly. Wallpaper should be hung over smooth walls primed with a product designed to be used under wallpaper. Not paint primer and not bare Sheetrock and not glossy paint overspray around the woodwork.

2, Humidity is the great enemy of wallpaper. Especially in a small enclosed bathroom with poor ventilation. If your home has this environment, make sure to run the exhaust fan while showering, and leave the bathroom door open for ventilation, so the humid air can circulate out and fresh, dry air can venture in.

3, Manufacturers tout solid vinyl wallpaper as ” bathroom ” paper because splashed water will run off it. But this is misleading. What’s also going to happen is that humidity will find its way in between the wallpaper seams and then into the gritty manila-type paper backing. Once that backing absorbs moisture, it will expand. When that happens, it will push away from the surface, creating the curled seams you see here.

Taking it a step further, often this paper backing will actually delaminate from the decorative vinyl layer.

Tjhis is not a ” loose seam ” and cannot be glued back down. Your bet bet is to strip off all the wallpaper, properly prep the walls, and hang new paper.

Stay away from the low-end pre-pasted, paper-backed, solid-vinyl papers. A better option would be a thin acrylic-coated paper (not vinyl) or one of the newish non-woven (part polyester) papers.
