Mildew on Wall Indicates Moisture Problem – Somewhere

October 9, 2018


I have just stripped off a solid vinyl wallcovering that had been up for at least 10 years, possibly twice that. The entire wall was covered with mildew. The mildew was present just on the exterior wall; not any of the walls that connected to interior areas of the home.

Mildew breeds when there is moisture. This indicates that there may be a leak in the home’s siding, or a leak in a window on an upper floor allowing water to get inside the wall and into the drywall. Another possibility is that plumbing inside the wall could have sprung a leak, and also caused the drywall to become wet.

Because the wallcovering was solid vinyl, it trapped the moisture between the wall and the wallpaper, and that allowed mildew to grow between the two surfaces. I’m rather surprised that the mildew didn’t penetrate through the wallpaper and show on the surface. The drywall didn’t appear to be soggy or rotted or compromised.

Another reason why I don’t like solid vinyl wallpapers.

Mildew!

December 13, 2017


You can clearly see the mildew on the wall that was revealed when I removed the wallpaper. It shows up as the black rings / circles.

The mildew was caused by moisture trapped in the wall by both a leak in the roof or siding, and a leak from a bathroom that crept under the floor – compounded by being trapped inside the wall by a solid vinyl wallpaper that would not breathe or allow air to pass through. Another reason to avoid paper-backed solid vinyl wallpaper.

Note: This issue was with mildew. Mildew is not nearly as dangerous as mold. Still, the homeowner took the contractor’s advice and had the drywall completely removed and replaced.

Grasscloth Wallpaper in a TV Room / Sunroom

I hung a woven grasscloth in this TV room / sunroom in an older home in the Rice Village area of Houston when the homeowners first bought the house – back in 1992 ! The wallpaper was still in great condition – except for where shower pan in the upstairs bathroom had leaked, causing damage to the wallpaper below. The paper had suffered fading from the abundant sunlight in the room, too. Time for a change.

The homeowners considered other types of paper and patterns, but came back to the natural, earthy, textured look of grasscloth. Their new choice is more relaxed than the previous woven one, and has more color – although it’s all in the neutral / brown / tan scope.

I was pleased that there was minimal shading / paneling (color variations between strips) (see 3rd photo). The material has a lovely texture (last photo), and was reasonably easy to trim and position.

There was no brand name on the product label, but it was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.
