Preventing a Stain from Bleeding Through

July 31, 2021

See that oval ring on the paint? That’s from someone lying on the bed and letting his head rest against the wall. Don’t know whether he used hair tonic or not, but even a clean head of hair will contain oils, and those oils will wick into the paint and cause a stain.

The bad thing about this and wallpaper is that certain substances will bleed through wallpaper, staining the surface. Oil and grease are sure contenders.

To prevent this bleed-through, I painted over the stained area with a stain blocker. My favorite is KILZ Original Oil Based. It stinks to high Heaven and breathing too much will make you high, but it is outstanding at sealing all sorts of nasty substances.

Wallpaper paste will not stick to this, so, once it’s dry, roll your usual wallpaper primer over it.

Before. Original chalkboard paint sealed off with KILZ Original to block any oil residue from chalk that might bleed through the wallpaper. Then primed with Roman 977 Ultra Prime wallpaper primer.
Finished. Airy, floral, fun place to work!
First strip goes up, lined up against the red light of my laser level. I measured and plotted the placement so that the center of that dominant black flower would drop along the vertical center line of the wall (about 8″ to the right of the laser line).
Detail. I like the shadows in the background.

Working from home these days, the homeowner wanted an office that was bright and encouraged creativity. The black chalkboard paint scrawled with slogans and proverbs had to go!

Almost exactly a month ago, I prepped the walls and started to hang the paper – only to discover printing and trimming defects. See my post from May 26, 2021. The on-line vendor, Burke Decor, was quick to ship out replacement paper from a different run. The new paper was fine.

The new light sconce plays off the black and gold colors in the wallpaper.

This refreshing yet peaceful abstract floral pattern sets the perfect tone, when your office is in your home.

The home is in the Heights neighborhood of Houston.

Worrisome Stains on Wall

April 13, 2021
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.

Trading in a Slew of Stubbies

March 23, 2021

No wonder I can’t fit a screwdriver into my toolbox – these too-small-to-hold-on-to nubs and stubs are taking up all the space. No more!

A trip to the dollar store yielded me these two long-lived and easy-to-hold #2 pencils – plus 10 more for back-up.

Note: We contractors always write on the wall and on our materials with pencil or chalk. Ink, marker, grease pencil, or other such materials will bleed through and stain wallpaper and paint and most other substances.

Addendum: Old habits are hard to break … I might hold on to the two on the right.

Mirror Tar – Bad For Wallpaper

January 24, 2021

Mirrors are commonly attached to walls with mastic – a sort of tar adhesive. When installing this new mirror, the workmen got some of the tar smeared on the wall below.

This is bad. Tar, like many other substances, will bleed through paint and wallpaper.

So this stain will need to be sealed over with a stain blocker. Or, better, cut out of the wall entirely, and then the damaged wall will have to be repaired. Learn more on this by doing a Search in the upper right corner.

Weird Bubbles Develop on Wall

January 21, 2021

This wall had a slight texture that needed to be skim-floated and then sanded smooth. After I applied the smoothing compound (drywall joint compound), a half hour or so later, these tiny blister bubbles appeared. This is off-gassing. But from what is a mystery.

The only clue is that this area is around where the hand towel was positioned next to the sink. So this area would have received a lot of splashing of water and also soap and other toiletries.

My guess is that some of these substances stuck to the wall. And for whatever reason, when they were covered by the joint compound, they released air / gas, which caused these bubbles.

I’ve seen this before. But this time, some of the bubbles were large enough that they did not sand down smooth and even with the wall surface. So I had to do a light touch-up skim-coat on top.

Once I got the wall smoothed, I wasn’t too concerned. I don’t believe that anything causing these tiny blisters would be something that would bleed through and stain the wallpaper.

Some substances do stain wallpaper, though. For more on that, do a Search here.

Don’t Let Water / Toiletries Splash On The Wallpaper

January 20, 2021

Very hard to see here, but look closely and you will see vertical stains running down the wall.

This wall is right behind the sink. And this spot is right below the hand towel. Obviously, people reaching for the towel with wet hands has led to water – sometimes tainted with soap, toiletries, or cleaning agents – to drip down the wall.

The resulting stains are minor on the painted wall. But, once the wallpaper goes up, it is possible that these substances will bleed through the primer and the wallpaper and cause staining on the new wallpaper. So, proper remediation is needed to prevent stains from bleeding through.

Also, once the new paper is up, people will need to be more cognisant of not splashing the wall.

It’s a misconception that wallpaper is “washable” or “stain resistant” or “will hide flaws.”

Best to treat your new wallpaper with care.
