Teeny Dots Could Stain Wallpaper

December 27, 2022

Top photo … my razor knife is pointing at pin point-sized specks on this wall. I found similar in multiple spots around the room. What’s interesting is that I have seen these exact same size, color, and configuration of specks on at least one other job.

What’s scary is that I fear these are made of something that will stain the wallpaper. There are lots of substances that can bleed through – through paint, through primer, and through the wallpaper and appear on the surface.

These could have been splashed onto the wall. But my feeling, especially since I have seen it in other homes, is that they are coming from within the wall surface. Maybe something contaminated the painter’s materials, or something inside the drywall.

There are stain blockers that can be used to seal these dots. My favorite is shown in the second photo. Oil or shellac-based work best. The problem is, wallpaper paste won’t stick to them. If just daubing onto a teeny dot, I wouldn’t worry about it. But when a larger area needs to be treated, you have to let that dry, and then follow up with a wallpaper primer.

Actually, depending on the stain, I don’t always trust the blockers. For these very tiny specks, I used my razor blade to dig into the wall and actually remove the affected area. The resulting holes were small enough that I didn’t worry about dents showing under the wallpaper.

In some instances, I did go back and cover them with KILZ.

Working Safely Over a Bathtub

November 30, 2022
This vintage tub is super cool , and period-appropriate to this 1926 home in the Woodland Heights neighborhood of Houston . But if you need to get wallpaper on the walls around and above it, it’s really tricky . A ladder won’t fit in the tub , nor straddle it, and might damage it as well.
So I keep this handy piece of plywood in my van . It’s a standard 2’x4′ size, and 1/2″ thick. That’s thick enough to distribute and hold my weight, but still light enough that I can carry it into homes and up staircases .
It’s been sanded and then primed with white KILZ , to look a little nicer bringing into my clients’ homes, and also to reduce the chance of it leaving a mark on surfaces .
The board is a perfect size for placing over various types of bathtubs or other items – as long as their top is flat. Note that I have cushioning and non-slip material between the board and the tub.
In this case, I’m also using a one-step Rubbermaid step stool to boost my height.
This might look a little scary, but it’s all actually very safe . I just need to be sure that my weight is distributed over the tub, and not over that unsupported section on the right.
The stool does add a little more interest to the balancing act. But it’s all doable and safe if you just pay attention to your weight and movements. It did help that this family gave me plenty of peace and quiet while I was working .

Wallpaper Paste Residue = Crackled Ceiling Paint

July 13, 2022

You’re looking at the junction between a wallpaper border at the top of a wall and the ceiling. You can see crackled and flaking paint on the ceiling.

This was almost surely caused by the previous wallpaper installer getting paste on the ceiling (which is typical and normal) but failing to wipe it off completely.

The paste is clear and difficult to see. Even when you do a diligent job, it’s easy to leave some residue behind.

The problem is that wallpaper paste attacks water-based paint, and will cause it to do what you see above … crackle, flake, chip off. This can happen if the paint was in place before the wallpaper paste got on it, or if there was paste residue and fresh paint was applied on top of it.

In fact, the decorative paint finish called “crackle finish” is accomplished by applying hide glue onto a surface and then coating it with latex paint.

The crackly paint on the ceiling is unattractive, and impedes adhesion. It takes a lot of scraping and sealing and skimming the wall to rectify this.

A way to avoid this is to astutely wipe off all paste residue. Better yet, what I do is to use special plastic tape at the top of my wallpaper strips, so that no paste gets onto the ceiling in the first place. Do a Search here to see previous posts describing that technique.

You can also use a stain blocker like KILZ Original oil-based primer, or BIN shellac-based primer, to seal off the area before painting. There are water-borne primers that claim to seal such problem areas – but I prefer to stick with oil or shellac.

Stains on Wall Around Crib

March 20, 2022
Look carefully and you’ll see an oval-shaped dark area on this wall. Stains have soiled the high areas of the textured wall. This is where the crib was up against the wall. Probably the child ran her hand or feet across the wall. Over time, oils from our skin can cause stains like this.
Before smoothing the wall, I applied a stain blocker to this area, to prevent anything from bleeding through the new wallpaper.
I like oil-based KILZ Original best, but there are others out there. BIN by Zinsser is another good option.
The smoothing compound and / or wallpaper primer then goes over the stain blocker.
Additionally, once the new wallpaper is up, it’s important to protect the wall and take steps to prevent new stains from developing.

Food Stains on Wallpaper

his wallpaper is on the backsplash of a kitchen counter. Over 30+ years, you can see splatters that have stained the paper.

On these pieces that I have stripped from the wall, you can see that the stains have leached through to the back of the paper. Since stains like this usually contain grease, they can bleed through to the new wallpaper, too. So it’s important to make sure that none have gotten onto the drywall behind the wallpaper. If so, a stain blocker will be needed to seal them off. Oil-based KILZ and shellac-based BIN are two good options.
On the right is the KILZ that I used to seal off these stains. It’s important to use the ” Original ” oil-based version, and not any latex or water-borne formulas…. they simply don’t perform as well, no matter what the label says. And know that the fumes are … well, they will get you high and knock out a few brain cells, so wear a respirator, or at least open the windows for good ventilation. Wallpaper paste will not adhere to oil-based products, nor will it stick well to the glossy surface of BIN. So, once the stain-blocker is dry, I go over it with my usual wallpaper primer, Roman Pro 977 Ultra Prime.

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.

Candice Olson “Linden Flower” in Home Office

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.
Close-up shows pen & ink, and water color look of this design.
Manufacturer is York, one of my preferred brands. http://www.yorkwall.com

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.

Fixing Weird Things That Happen To Wallpaper

December 6, 2020

The top photo shows a stain on the wallpaper that is probably related to a rain or hurricane event a few years ago.

Water stains (and also other substances, like rust, blood, ink, oil, tobacco, tar, cosmetics, and more) will bleed through wallpaper. So, before patching the area, it is imperative to use a stain blocker to seal the problem. My favorite is KILZ Original oil-based.

KILZ will seal off the stain all right. But wallpaper won’t stick to it. So, in the third photo, you see where I have primed over the KILZ with a wallpaper primer (tinted light blue, for visibility). It’s not necessary to prime the entire wall area to be patched, because this type of wallpaper will stick to itself with just plain old adhesive.

The striped pattern made for an easy repair. I took a straightedge and sharp razor blade and trimmed along the striped design, creating a long skinny patch. See fourth photo. You can also see the strip pasted and booked (folded pasted-side-to-pasted-side).

Once that sat and relaxed for a few minutes, I took it to the wall and appliquéd it over the damaged area, going the full height.

There was a very slight color difference between the paper that had been on the wall for 20 years and the paper that had been in a dark closet. Had I placed the white area of the patch next to the white area on the existing paper on the wall, the color difference would have been noticeable. But trimming along the blue stripe gave the eye a logical stopping point, and so the color difference is not detectable.

In the finished photo, you would never guess there had been anything amiss with this wall.

I used this same technique to patch over the bug-bite holes in yesterday’s post.

And another good reminder that it’s always best to order a little extra wallpaper, in case of the need for repairs later. Store the paper in a climate-controlled space … not the garage or attic.

The wallpaper is by Schumacher, and appeared to be an old-school pulp paper material.

I Love Stripping Off My Own Work!

November 30, 2020

Digital Image
I hung this mattress-ticking striped wallpaper in the tub / toity room of a Hollywood bathroom in West University 8-10 years ago. (Still in perfect condition, too, I might add. 🙂 ) The boy and girl who share the bath are older now, and the homeowner wants to update the décor.

The paper clung to the walls during all that time, yet, when I started stripping it this morning, it came off fairly easily, by simply soaking with water to reactivate the paste, and then gently scraping. What’s best is that my primer (KILZ Original) protected the walls, and the surface is perfectly intact, with no damaged areas and patching needed.

In addition, I am not going to reprime the walls, because the original primer is dependable enough to work under the new paper, which I will hang tomorrow.
