Dampness in Walls = Problems with Wallpaper

December 2, 2020

Digital ImageI hung this wallpaper in a dining room in Tanglewood a few years ago. In that time, the house has had some settling issues, and some moisture issues.

In the first photo, you see a seam that is perfect. It is a seam on an interior wall. In the second photo, you see a seam that has separated a little – not just separated, but the surface of the wall underneath has actually pulled away from the sub-surface, creating a little curl and gap. This is an exterior wall.

I believe this happened because moisture got inside the wall, and compromised the layers of Sheetrock, paint, joint compound (used to smooth the textured wall before applying wallpaper), primer, and paper. The seams in wallpaper create a weakness in the surface, and provide an opportunity for the wall to give way, if a stressor is placed on it. Stressor? This could be expansion and contraction due to temperature, humidity, moisture, foundation shifting, etc.

Unfortunately, there is not a quick cure for this, and involves resurfacing the whole wall area. AFTER, of course, fixing the source of the leak.

This wallpaper is by Osborne & Little, a British company that prints on what we call pulp paper substrates. The interior designer is Shirley Webb, and I love her rooms and I love working with her.

Water Stains on Wallpaper

March 21, 2017

This wallpaper has been up for 10, and possibly as long as 20 years.

It is an uncoated paper wallpaper, probably the type that we call a British pulp. It is in a bathroom, and, over time, water splashing onto the backsplash (or possibly the housekeeper’s cleaning solution) has been wicked up by the paper, and caused the water stains you see here.

A paper with a thin vinyl coating, like most American papers have, might have held up a little better. Also, a thin bead of clear caulk along the top of the backsplash might have prevented water from getting into the cut edge of the paper and discoloring it.

There are good things to be seen here, too. Thin papers like this one (as opposed to paper-backed solid vinyl wallpapers), stay nice and tight to the wall, even in humid rooms like bathrooms, and even when water is splashed on them. Over all the years this wallpaper has been up, all of the seams are perfectly intact. And even though there is staining where water has gotten into the paper, the paper has stayed nice and tight against the wall and the backsplash. A paper-backed solid vinyl would have curled away from the wall, and would have looked much worse, and been impossible to repair.

Another reason to buy paper, and stay away from paper-backed solid vinyl.
