Worrisome Stains on Wall

Drip stains on wall to left of countertop, from splashes and from spray cleaners.

Stain drips show up under my primer.

Dot-shaped stains show up under my wallpaper primer.

These stains were not visible until my primer went onto the wall.

My favorite stain blocker.

Some stains, like the top photo, I saw immediately. Others, like the next three photos, didn’t show up until I had applied my wallpaper primer. The primer adheres to the wall paint differently from how it adheres to the splashed substances.

I’m always worried when I see stains on a wall, because certain substances will bleed through wallpaper (and paint, too). Things like tar, tobacco, water, oil, ink, wax (crayon, candles), smoke, rust, food splatters.

In this bathroom, the splatters and runs are probably from toiletries and cleaning agents. But still, I worry that they may work their way through the new paper. It may not happen immediately, but eventually you may see marks, or maybe just ghostly shadows.

There are water-based stain blockers, but I prefer the old-fashioned shellac-based (BIN by Zinsser) or, my all-time favorite, oil-based KILZ Original.

Wallpaper won’t stick to modern oil-based products. So I had to apply the KILZ, let it dry, and then roll on my wallpaper primer (I like Romans Pro 977 Ultra Prime) and let that dry, before the paper could go up.

Now no worries about mysterious shapes and shadows showing up under the new wallpaper.

New Label Material Allows Drips

Here is my favorite wallpaper primer – Ultra Prime Pro 977 by Romans.

It appears the composition of their paper label has changed. Previously, the label was absorbent, so any drips that formed would soak into the paper.

But now, even though the label looks the same, it’s made of a new material that allows drips to run all the way down the side of the can. Even if I wipe them away, they reform and continue to slide down the can.

This means there is great potential for these drips to reach my dropcloths (see photo). The dropcloths will protect the floor, no problem. But once they get a certain amount of drips and splotches, even though they may still be serviceable, they don’t look good in a client’s home, so have to be discarded.

Besides ruining the dropcloths, there is also the chance that an errant drip of primer might find its way to the homeowner’s floor, carpet, countertop, or furniture.

I have written to the Romans company, and I hope they listen to my feedback and go back to their former type of label on their cans.

UPDATE: I chatted with the company rep today, and she confirms that they have, indeed, changed to a new manufacturer, and that company does use a plasticized coating on the label. That explains why the primer slides rather than soaks in.
