Treating Mildew on Walls Before Wallpapering

July 11, 2018


When the old wallpaper was pulled off, surprises were revealed! Here you see mildew (don’t worry, it’s not mold) that had grown under the paper where a water leak had lead to damp conditions, probably exacerbated by the thick, non-breathing, vinyl wallpaper.

Mildew will bleed through wallpaper, and it can also create a powdery colony that will not provide a stable surface for the wallpaper to grab ahold of.

To kill the mildew, I washed it with full-strength bleach. When that was dry, I went over it with an oil-based stain blocker. I like the product KILZ Original.

Wallpaper – Twos are Bad News

The homeowners were testing colors of paint for their woodwork. No problem with that. But what WAS a problem is that they labeled those choices by writing numbers on the wall with a Sharpie – in INK!

Ink bleeds through paint, and it bleeds through wallpaper. The stain might not appear immediately, but over time, the shadow of this “2” would eventually work its way through the new wallpaper.

There are sealers that will cover this (I like oil-based KILZ Original). But in this case, since the spots were small, I used sandpaper to scrub all traces of the ink off the wall.

For the record, there are other substances that will bleed through wallpaper, too. Ink, blood, rust, water stains, and any oil- or petroleum-based material, like crayon, lipstick, baby oil, cooking oil, grease, pet stains, etc.
