Stripping Solid Vinyl Wallpaper

April 21, 2018


This pre-pasted, paper-backed, solid vinyl wallpaper is one of my least favorite types due to its poor performance in humid areas. However, when it comes to stripping it off the wall, it’s one of my favorites. 🙂

Getting this paper off the wall is a matter of peeling off the top, printed, vinyl layer. This usually comes off in large pieces. The paper substrate layer will be left on the wall. That’s the light tan you see in the photo.

That layer gets soaked with a wet sponge and warm water. The backing will turn darker tan when it’s good and wet, as shown in the photo. It usually takes several applications of water, over a period of time, to reactivate the adhesive enough that the paper can be removed.

Sometimes that backing will simply and cooperatively come away from the wall. Other times you will need to use a stiff 3″ putty knife to gently scrape it off the wall, taking care to not gouge the wall or tear the drywall.

If the previous installer primed the walls, all this should go fairly easily and with minimal damage to the walls. But if no primer was used, it may take more care, time, and a little repair work to fix any damage to the walls.

A Possible Good Quality Pre-Pasted, Paper-Backed, Solid Vinyl Wallpaper

March 8, 2018


In previous posts, including one day ago, I have railed against the lower-price-point, pre-pasted, paper-backed, solid vinyl wallpapers. Do a Search here to find out why.

But today, at the end of a 9-day job in Bellaire, where each of the four bathrooms was using the same brand of wallpaper, this final pattern (in a powder room) actually went up beautifully.

The seams laid down nice and flat, there was no bubbling, no curling, no fighting with it. Even I could not find the seams!

I noticed three differences. First, the vinyl on the surface was smooth, instead of the lightly textured faux “satin” look on the other two patterns. Second, the paper backing seemed smoother, as contrasted to the somewhat gritty, porous paper backing on the other patterns. Third, the pre-paste applied by the manufacturer to the back of the paper was smoother and more gel-like, instead of the dry, globby, cantankerous paste on the other papers.

It’s too early to tell how this paper will hold up under humid conditions. But I have much more hope that it will not absorb humidity from the air, and will stay nice and flat to the wall.

The manufacturer is “Exclusive Wallcoverings” and is a British company. I’m not saying I love this paper, but it appears to be better than most of the pre-pasted, paper-backed, solid vinyl offerings out there.

From Diagonal to Vertical

March 3, 2018


This home in Bellaire was (Houston) built in the ’90’s, and the original wallpaper (top photo) in this bathroom was outdated and had begun to curl at the seams. I stripped off the old paper and primed the walls with Gardz, a penetrating sealer that is a good base for wallpaper to adhere to. See second photo.

The new tone-on-tone blue striped wallpaper updates the room, and adds a softer look. The homeowner chose cherry red accessories to accent the room. These are toned down by navy blue rugs and towels that are a slightly duskier navy and red.

This paper is a pre-pasted solid vinyl on a paper backing. Despite the economical price-point, I don’t recommend these types of papers, especially in rooms that are prone to humidity, such as bathrooms.

For starters, it’s difficult to install, and the seams never really look good. Second, the paper backing tends to absorb moisture from the air and then expand, and that causes the seams to curl. The vinyl surface layer is known for delaminating (separating from that paper backing). This, again, results in curled seams. This is not something that can be pasted back. So you are either left with curled seams or faced with repapering the entire room.

The best way to (hopefully) avoid this is to properly prep the walls, and to keep humidity to a minimum (avoid steamy showers, keep the A/C / heating vents open, run the exhaust fan, keep the door open).

Better yet, avoid purchasing paper-backed solid vinyl wallcoverings. If you shop at my favorite place (see the page on the right), you will be steered to beautiful papers of a better quality, while still at affordable prices.

Don’t Buy Paper-Backed Vinyl Wallpapers – Bad Seams

Today’s wallpaper was a pre-pasted solid-vinyl material with a somewhat gritty manila paper type backing. These papers are usually in the lower price spectrum. These papers are also my least favorite type of wallcovering.

In the upper right of the photo is a seam that is what I call pooched. Puckered just a little. Other parts of the seam gapped a little. There were many areas that curled and would not lie down flat against the wall. I tried three pasting methods with the paper, but none of them left really good looking seams.

Did I mention that I hate paper-backed, solid vinyl wallpapers? The problem is that the paper backing absorbs moisture from the wet paste and expands. That expansion pushes the vinyl surface backwards and creates the little bit of curl at the seams. Often, this will lie back down once the paper is good and dry (which can take a while, because it’s plastic and there is nowhere for the moisture to go because it can’t pass through the plastic). But not always.

Now, if the seams curl when they are wet with wallpaper paste, how do you think they will perform when your teenager takes 40-minute showers and steams up the room, or on those days when you turn off the A/C and open the windows to enjoy the fresh air – a.k.a. Houston Humidity?

Did I mention that I hate paper-backed, solid vinyl wallpapers?

This paper is by Exclusive Wallcoverings and was made in England.

Better options would be a vinyl coated paper (similar terminology, but a big difference in material content), or one of the newer non-woven substrates, preferably the thinner ones (like the Sure Strip line), rather than the thick, spongy, or stiff ones.

Signs of a Humid Room

The Great Enemy of wallpaper is humidity. That is why some papers are not a good choice in some bathrooms. I particularly dislike solid-vinyl material on a paper backing, as they tend to absorb moisture and expand and curl and delaminate (vinyl detaches from the paper backing). You can see this happening in the top two photos.

The third photo is harder to see, but it is a shot of where I have removed the light fixture and you see the electrical box where the wires are connected inside the wall. Humidity has caused the screws on either side to rust and corrode. And the strap is completely rusted. (A strap is the metal bar that crosses the box and to which the light fixture is attached via a threaded nipple. In this picture, the screw on the right has been removed and the strap is the dark metal bar in a vertical position.)

What is intriguing is that humidity is present not just in the bathroom itself, which would be attributed to hot showers and poor ventilation, but also behind the wallpaper and inside the wall, sufficient enough to cause rusting inside the electrical box.

This is a 1930’s era home that was constructed with shiplap wood and lathe and plaster. It has been updated with modern air conditioning, but still has the original walls and wiring, and ventilation is probably not as adequate as it should be. There is no vent exhaust fan in this bathroom, either, so humidity from a hot shower would just hang out in the room until it dissipates over time.
