Paint Doesn’t Stick to Plastic

June 15, 2022

You are looking a the plastic escutcheon / decorative cover to hide plumbing pipes under this pedestal sink.
Someone painted it the same color as the wall, and with the same wall paint.
Only problem is, most paints won’t stick to plastic. Plastic is too slick.
That’s why now the paint is peeling off with just the slightest tug or tension. It’s peeling away like a snake shedding his skin.
There are some solutions for this. For starters, the plastic could have been sanded, to give the paint some “tooth” and something to grab ahold of. There are also primers that will adhere to plastic and prepare it to take the paint.
Even simpler, there are paints formulated to stick to plastic. Krylon makes some, and I’ve used it on my outdoor lawn chairs; it’s held up nicely for about 20 years.

Strawberry Thief in Spring Branch Powder Room

June 12, 2022
Textured wall before smoothing .
Done!
Shot of a corner, showing more of the pattern. The color is off … see below…
This murky blue is a more accurate depiction of the color. Strawberry Thief comes in many colors.
Striping dark paint on the wall under the seam areas, to prevent the white wall from peeking through, as it’s common for teeny gaps to open at the seams of wallpaper .
I use bottled paint from the craft or art store, diluted with water, and apply with a scrap of sponge, on top of my wallpaper primer. It’s important to not make the paint too thick, as it’s not formulated for wallpaper to grab ahold of.
British Heritage is the brand. William Morris designed Strawberry Thief about the turn of the last century. I’ve noticed a real uptick in interest in Wm. Morris patterns lately. This is my fourth installation of this particular design this season, and have done others recently, too. Do a Search (upper right) to see other jobs I’ve done.
This is a non-woven material, and can be hung by pasting the paper or pasting the wall. It’s durable stuff, more stain-resistant than many other options, and is designed to strip off the wall easily and in one piece when it’s time to redecorate.

Another Installer’s Problems With British Pulp Paper

May 31, 2022
Scroll down a few posts to see where I hung this exact same pattern, and coincidentally just a few blocks away. I had absolutely no problems. Yet this poor installer struggled and ended up with many dissatisfactory issues.
In this photo, you see where the wallpaper has shrunk at the seams and left a gap, some tears, and a patch to cover a mishap.
More tears and gaps.
Paper coming lose from the wall. Not taking primer or paint with it. But you can see the adhesive clinging to the back of the paper. I’m suspecting this is clay adhesive. Nothing wrong with clay, but I prefer one of the vinyl-based adhesives.
Not sure what the guy used as a primer (if any).

This is the popular Strawberry Thief by William Morris , usually sold by Morris & Co. I’m believing the problem here is the material on which this pattern was printed.

The site from which this was purchased called it a ” heritage ” paper. It is, indeed, made of what we call a British pulp material. Old-fashioned, it is. These days, most wallpaper coming from the U.K. is printed on non-woven stock. The paper I hung a few days ago was non-woven.

Pulp wallpapers have a nice look. But they have no protective coating, so become soiled easily. They soften when wet with paste and tear easily, and can also shred under the razor blade while trimming. They expand when wet with paste, and then shrink as they dry, which often results in gaps at the seams.

Even skilled installers can have difficulties when working with this stuff. In fact, on the private Facebook page of the Wallcovering Installers Association ( WIA ), we have just been discussing this very same topic.

I believe this previous installer had a few shortcomings, such as lack of skill and maybe used the wrong or no wallpaper primer. But I think the real and unsurmountable culprit was the substrate.

Moral: If given the option, choose a non-woven material. They are made with minimum 20% polyester content, and thus are resistant to shrinking, tearing, and tension at the seams. Many other advantages, too. Non-wovens are also referred to as paste the wall .

It’s A Misconception That A Liner Will Smooth A Textured Wall

May 25, 2022

A theory has been circulating for decades that a liner disguise texture or imperfections in a wall. A liner is a special paper applied to the walls before the actual decorative wallpaper goes up. It has its purpose – but smoothing walls is not one of them. At least, not in my opinion.

Here you see an area where a pedestal sink has been removed. In so doing, part of the drywall was torn away (the reddish brown area) and the wall surface is left uneven.

I’m using liner in this room for another reason. Here it has been applied over the damaged area. As you can see, the uneven texture of the wall shows right through (we say that it telegraphs ). Once the liner is good and dry, it will shrink and pull even tighter to the wall, and the ridges underneath will be even more visible.
And once the wallpaper goes up, all this will telegraph through the new wallpaper, as well.
Here’s the liner paper I used today. It’s a fairly thick, stiff, non-woven material, so has more ” bridging ” power than other types of liner paper. Still, as you see above, it’s not enough to smooth textured or uneven wall surfaces.
The only way to properly and thoroughly smooth a textured wall, IMO , is to skim-float it and then sand it smooth, and then apply a wallpaper primer. Please do a Search here (upper right corner) to find previous posts on this process.

Making the Best of Plumbing Problems

May 22, 2022
OK, so this master bathroom suffered a water leak, and the plumber had to cut through the drywall in the potty room in order to access the shower fixtures.
Here the contractor has replaced the cut-out piece of Sheetrock. He did a really nice job. For the most part. Of course, he didn’t bother to remove the wallpaper before doing his repairs. This is vinyl paper (thick, slick, slippery, backing absorbs moisture) and really should have been removed first.
But I was able to work around the patched-in area.
The prep for this small room was a lot more involved than I anticipated, and required an extra day. Too complicated to get into, but there were two layers of wallpaper, and no primer by either of the previous installers. Original install dates back to the ’80’s. It took me a day and a half just to do the prep on this small commode room.
The room finished. Note the stripes centered nicely on that back wall.
The pattern and material were chosen to coordinate with the green stripes in the main area of the master bathroom.
Kill point (final corner) over the door. I “shrank” some sections in order to get even widths and maintain the pattern repeat and match.
The plumbing problem also damaged an area on this wall outside the water closet. So this area around the door needed to be replaced. The homeowners didn’t have any left over paper, so they chose something similar in color, style, and composition to the green striped paper you see to the right.
Here is that transition door wall finished.

We decided to use the stripe to define the ‘break’ between the two patterns.
The alternative would have been placing the stripe against the door molding … but I felt that would be too repetitive, plus it would have left a cut-off section of flowers running along the side of the green stripe, and same on the opposite side of the door frame.
And, yes, the wall definitely is not straight, square, or plumb.
And here is that opposite side of the door frame, with the stripe running nicely along the shower tile.
Some overlapping was involved in this job. Since the wallpaper is vinyl, and vinyl is slick, you need a special paste to be able to grab ahold of the glossy surface. These days, I sure don’t use often border paste, also sometimes called VOV or Vinyl Over Vinyl . But I was mighty glad to find this 10+ year old container deep in the bowels of my van. Still fresh and sticky, too!
Besides borders not being popular today, these “satin” and “silk” look wallpapers are not very common. But this is exactly what the homeowners were looking for, to coordinate with the existing, 30-year-old paper in their master bath. Saved them having to replace all the wallpaper in both rooms!
This paper is very economical, too. The couple shopped with Dorota at the Sherwin-Williams in the Rice Village, and she was able to track down the perfect material, pattern, and color.
Now, aside from all the positive things I just said about this paper in this current application, I do want to make clear that I am not at all fond of this type material. Without getting into a long schpiel here, please click and read the page link to the right “Stay Away From Pre-Pasted Paper-Backed Solid Vinyl …. ”
I will also add that I’ve developed a technique to work with these materials, and so far the installs, including today’s, have been going nicely.
One double roll bolt had some of these blue mark printing defects running through about half of it. Luckily, most of these were on a section of paper that was cut off in order to turn a corner, so was discarded and not put on the wall.
Exclusive Wallcoverings is the manufacturer. Usually I work with their non-woven or traditional paper products, which are quite nice.
The home is in the West University area of Houston.

It has a hand-painted watercolor look.
Simply called Jungle Wallpaper Mural , it’s by Lulu & Georgia , and is made by York , in their Sure Strip line. Sure Strip is a pre-pasted product that is designed to strip off the wall easily when you redecorate. I love this stuff! It goes up like a dream, and will hold up for eons until you’re ready to redecorate.
This mural comes in four panels, and the overall size is 6′ wide x 9′ high.

Pearland Powder Room Update and Wake Up

April 15, 2022
Originally, these walls were sorta heavily textured, and painted a drab brown-tan. Here I’ve finished skim-floating the walls to smooth them, and applied my wallpaper primer. Ready for paper!
Flowering tree branches are a popular trend right now, and many companies are making their own versions of it.
Pattern is nicely centered on the sink wall.
The white background really perks the room up, and the light touches of metallic gold in the leaves helps bounce light around this small room.
Close-up. This material has a slight raised ink texture to it. I love the look and feel.
That scribble at the top reads Florence Broadhurst . She was an Australian artist / painter. This line of wallpaper patterns are based on her art and designs.
The pattern is called Branches and the manufacturer is York Wallcoverings, one of my favorite brands.
Pearland is a southern subdivision of Houston.

Wallpaper Woes in Chinese Restaurant

April 10, 2022
While waiting for my order to be ready, I couldn’t help but notice problems ….
Wallpaper starting to curl at the seams.
Wallpaper twisting in corners as the building shifts and drywall moves. This is pretty common in Houston.
Other signs of poorly maintained building and/or climate control issues.
Seam curling back. I believe this to be a lower-end solid vinyl wallpaper on a gritty paper backing – one of my least preferred types.
When the walls are not prepared correctly, and the paper is not hung properly, and when there is a lot of humidity (door left open, steam from kitchen getting into waiting area, A/C not running or turned off at night), humidity can enter into the seams and be wicked up by the paper backing. The paper expands and pushes away from the wall, causing the edges of the wallpaper to curl back.
The next step is that the vinyl surface can actually delaminate (come apart) from the paper backing. This is pretty impossible to repair.
At the very bottom, you can see the vinyl separating from the paper backing.
The wallpaper has been wrapped around this outside corner, and a new piece of paper overlapped on top of it. When this is done, with vinyl material, you’re supposed to use special vinyl-over-vinyl ( VOV ) adhesive, because regular wallpaper paste isn’t formulated to adhere to vinyl / plastic .
But even if the installer had used the correct adhesive, under humid conditions or with improper wall prep, the odds are that this wallpaper job will start to fail.
Also note dirt along the ceiling, and along the chair rail in the previous photo. General lack of maintenance and I am really suspecting lack of climate control.
The black smudges appear to be mildew coming from underneath the paper. Again, probably related to humidity.
Vinyl wallpaper is a sheet of plastic, and moisture can be trapped behind it. That can be a breeding ground for mold and mildew.
So why use vinyl wallpaper? Mainly because the surface is much more washable than most other types of wallpaper. In a business, washability is attractive.
But these property owners chose a low-end vinyl product, most likely skipped proper wall prep such as a wallpaper primer, and have not provided a hospitable environment for the paper.
There are other vinyl wallcoverings that would have held up better. For instance, vinyl on a scrim ( woven fabric ) backing, or the newer backing called non-woven , which has a 20% polyester content, and therefore less likely to wick up humidity.

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.

Paint Peeling Off The Wall – A Bad Harbinger

March 16, 2022

Prior to prepping for wallpaper, I’ve removed a hanging shelf. It had stuck to the paint, and pulling the shelf off the wall also took some of the paint along with it.

This is a bad sign. If paint will release from the wall so easily, it’s an indicator of an unstable surface underneath, that the paint is not able to bond to.

That also bodes poorly for any coatings applied on top of it, such as my smoothing compound, primer, and wallpaper.

The most worrisome of these is wallpaper. Because unlike other substances, wallpaper expands when it gets wet with paste, and then as the paste dries, the paper shrinks a tad and puts stress / torque on the wall. If the underlying surface is unstable, these layers can actually pull apart, resulting in a ” popped ” seam.

This is not a ” loose ” seam and cannot be simply glued back together. It’s layers deep inside the wall coming apart / delaminating from each other, and virtually impossible to really repair.

So what causes this? Do a Search here to read my other posts on this topic. But causes can include incompatible surfaces, such as old oil-based paint covered with newer latex paint, gloss paint covered with new paint without proper prep / de-glossing, chalky or calcimine paint, or coatings applied to a dusty wall.

In all these cases, the top coatings won’t be able to adhere tightly, and can result in what you see here – the top layer(s) of paint pulling off the wall with just a little stress.

Even worse, in my world, is the potential of the surface beneath wallpaper seams coming away from the wall.
