Homeowner Tackled the Wallpaper Install – So, How’s That Working Out for You?

August 9, 2017

The homeowner tried tackling this wallpaper installation herself, without even consulting so much as a YouTube video. She didn’t do an all-out bad job, and the paper is still stuck to the wall after three years. But there are a number of things that were done incorrectly.

1. Walls were not primed with a wallpaper primer

2. Caulk should have been run around the top of the backsplash

3. Paper was wrapped around the edge of door moldings and not trimmed.

4. Seams were overlapped

5. Overlapped areas were not secured with a “vinyl-over-vinyl” adhesive.

6. Pattern was not matched.

7. And, last but very important – a poor choice of wallpapers.

I am not a fan of paper-backed, solid-vinyl wallpapers, especially the pre-pasted, lower-end products. Do a Search here on various terms, and you will learn a lot about the material and its poor performance. IMO

In the meantime, when I take on this job, I will remove all the old paper, scrub the walls to remove paste residue, fix any dings in the walls, prime with an appropriate primer, hang the paper properly, by matching the pattern, butting the seams, and trimming correctly along baseboards and door moldings, etc., and, when finished, I will run clear caulk along the top of the vanity and other key areas, then give the family my “lecture” about leaving the door open and using the exhaust fan and avoiding long steamy showers.


Brightly Nautical Wallpaper in a Master Bathroom

I didn’t get pictures of the original wallpaper, but it was a pre-pasted, paper-backed solid vinyl (my least favorite kind) and had been poorly installed on un-primed bare drywall. Over the 12 years it was up, humidity from the bathroom had penetrated the seams and caused the paper to curl.

This paper (not vinyl) wallpaper, hung over properly primed walls, will cling tightly to the wall and perform well for many years to come. Plus, it’s bright and pretty and adds a lot of life to the room.

One shot shows the oceanic paper in the main room, looking into the potty / water closet, which has been papered in a coordinating yellow striped pattern. I really like using two papers this way. See tomorrow’s post for pics of the potty room.

This home is in West University Place (Houston). The wallpaper pattern is #839-T-6701 by Thibaut Designs, and was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

Spring Time in a Powder Room

I forgot my camera yesterday, the day I stripped off the old paper and prepped the walls, so I cannot show you the 15 year-old wallpaper with its curling seams, due to 1.) being an inexpensive paper-backed solid vinyl wallpaper (my least favorite kind – do a Search here), and 2.) the previous installer did not prime the walls but instead hung the wallpaper directly on the new home’s bare Sheetrock, and 3.) age, heat, and humidity. The pattern, however, was not too dissimilar to this one, being a sort of “impressionistic painting” design in the same blue, pink, yellow, and green color scheme.

Anyway, the new powder room looks fantastic. The colors are similar to what the homeowner had before, but this wallpaper should hold up much better. The material is paper (not vinyl), and will hug the wall tightly. I removed every scrap of old paper and sealed the walls with a penetrating sealer named Gardz, and then primed with a wallpaper-specific primer called Roman’s Ultra Prime Pro 977.

On top of this good foundation, the new wallpaper is a pre-pasted, raised-ink paper by Thibaut, and is one of my favorite products to work with, and I also love it’s dependable performance down the road. The pattern is #6936, and is very similar to their “Augustine” hummingbird design (Do a Search here). I love the barely-discernible texture of these raised-ink papers. A unique printing process results in this effect.

Pouched Seams in Solid Vinyl Wallpaper

June 27, 2017

Digital Image

I hung this paper in a master bathroom back in 2001, and it has held up very nicely. But if you look closely, you can see that the seams are “pouched” up just a little.

This is a type of paper called paper-backed solid vinyl, and often comes pre-pasted, and is usually toward the lower end of the price point. I don’t like these papers because they have a habit of doing just this – curling every so slightly at the seams.

The reason, I believe, is that humidity gets into the seams and then into the paper backing. The paper swells, and the vinyl surface has nowhere to go, so it curls backwards on itself.

Better alternatives are acrylic-coated papers, or the newer non-woven wallcoverings.

Faux Grasscloth – A Handsome Choice

This young couple had had a faux-finisher do a textured strié pattern on their powder room and master bathroom walls, but they were not pleased with the look. They were considering grasscloth, but I discouraged that idea, because, in a bathroom, and in a home with young children, grasscloth will stain and even bleed if it is splashed with water or touched by little hands. Because it has no pattern that can be matched from strip to strip, you see all the seams. Toss in the color variations, shading, and paneling (do a Search here), and I pretty much discourage homeowners from using grasscloth.

A wonderful option is this faux grasscloth product. It’s made from vinyl and is backed with a woven fabric material (scrim), and is resistant to water, stains, and dings. In fact, it’s practically indestructible – it’s the same sort used in hotels and hospital hallways, where it will be banged into and abused, and still hold up. Furthermore, this product is thick and textured, so it delivers the tactile surface the clients were searching for. And, best of all, the color is uniform, so there are no issues with eye-jarring color differences between strips of wallpaper.

The finished look is tailored, serene, crisp, warm, masculine yet soft, and a good backdrop to just about any room or accessory.

Another big plus for this paper is that it is bonded to a woven fabric backing, and does not have a paper backing. The woven fabric adds even more strength, and allows for some flexibility if the walls move or shift (this is Houston, built on Gumbo Soil, after all). And they should not have any problems with lifting or curling seams in the future, even in humid conditions. Vinyl papers that are bonded to paper backings, on the other hand, do tend to absorb moisture from humidity and then expand, curling backwards, which means that the seams can open up and be impossible to glue back down. See previous post.

Did I Mention that I DON’T LIKE Solid Vinyl Papers?!

November 17, 2014

Solid vinyl adhered to a somewhat gritty manila-type paper backing, usually pre-pasted and at the lower end of the price scale, is one of my LEAST favorite types of paper. The photo at top shows you exactly why.

Under humid conditions, or, as in this case, where the original installer failed to use a primer under the wallpaper, it’s common for the seams to curl just a little. It’s not a loose seam that can be pasted back, but rather the material curling back on itself, and it’s virtually impossible to fix.

My theory is that the porous manila paper backing tends to absorb moisture / humidity, and when it does, because it is paper, it swells. But the vinyl surface does not expand and is forced to curl back on itself as the backing gets larger.

There is one redeeming quality about this paper, though. Well, two, actually … The first being that these papers are usually fairly washable, and also resistant to some surface stains. Just don’t brush your cleaning sponge crossways across the seam.

The best thing about them, though, is that they usually come off the wall fairly easily. They are called “peelable” papers, and here is the process:

In the second photo, on the left, you see the dark wallpaper still adhered to the wall. To the right, on the lower half of the photo, I have peeled the vinyl surface away from the wall, which usually comes off in pretty big pieces.

The paper backing is still clinging to the wall. No problem. All it takes is a sponge and a little warm water in a bucket. If you’re lucky, as I was today, the paper will peel right off the wall in large strips. At worst, you will have to gently scrape it off with a putty knife.

On the right half of the photo, you can see where I have wet the paper backing, and the water has darkened it. The paste has been reactivated, and the paper is coming away from the wall easily. At the top of the photo, the paper has already been removed completely from the wall, leaving a nice, clean, smooth surface.

Ready for a PRIMER – which the builder’s installer guy should have done in the first place.

NOTE: I am talking about solid vinyl papers with a paper backing, most of which are pre-pasted, and many of which are sold at a low price-point. The newer vinyls on a non-woven backing behave differently, and will probably hold up much better on your wall, without curling seams.

Please AVOID Paper-Backed, Solid Vinyl Wallcoverings!

August 2, 2014

Digital ImageThis curling at the seams, which is not repasteable or repairable (at least not if you want it to look right) is not uncommon when economically-priced paper-backed solid vinyl wallpaper has been used, particularly in humid rooms like bathrooms.

My theory is that the science is that moisture from humid air (teenagers taking 45-minute steamy showers!),works its way into the seams of the wallpaper, and is absorbed by the porous, gritty paper backing typically used on these types of wallpapers. The paper expands, and that causes the material to curl at the seams. These “curls” are usually hard and stiff, and really don’t respond to attempts to get them to reattach to the wall.

A liner under the wallcovering would probably benefit, because liners help to absorb moisture, while they also “lock down” the seams. However, liners add additional cost for merchandise and labor, and add at least a day to the job.

Much better, in my opinion, to steer away from “solid vinyl” materials, and buy “paper” or “vinyl-coated” or even the new “non-woven” wallcoverings.

Another Reason Why You DON’T Hang Wallpaper Over Wallpaper

July 14, 2013

Digital ImageThere are many factors playing into why this seam is failing. For one thing, it’s in a small, hot, humid bathroom with no air conditioning or heating vents.

But equally important is that it was hung right over the original wallpaper, without a primer.

Wallpapers usually have a vinyl or acrylic coating, which is somewhat slick, and won’t provide a good surface for another layer of wallpaper to get a grip on.

When the new paper dries, it pulls tight and puts stress on the edges, and that can mean curling seams as you see here.

A primer would have helped. But better would have been to remove the old wallpaper.

Before I hung the new wallpaper, I removed the green leaf paper, then the navy blue wallpaper below it. The old paper came off cleanly, right down to the bare drywall. It really wasn’t that hard, nor did it take much time. Shame on the previous guy who didn’t bother to invest a few hours to strip the old paper.

I let the walls dry, primed them, then hung the new paper – AND instructed the homeowners to keep the door open from now on, to expose it to a dry, air conditioned environment.

Curling Seams on an Imperial Paper

April 8, 2013

photo (18)I hung this paper yesterday.  See my post below.

The beautiful finished wall is deceiving – this paper was a bugger bear to work with. It was a pre-pasted wallpaper, meaning it has paste already on the back and is meant to be run through a water tray, booked, and then hung on the wall. However, when I followed the manufacturer’s instructions, there was intense curling at the seams.

Seams curl because the paper backing absorbs water and expands, while the inked surface cannot expand as much, so the paper curls back on itself. This paper had metallic ink, too (the flower stems), and that, along with the white ink, both curled more than the aqua background color. Meaning that there were parts of each seam that butted perfectly, and parts that curled away from the wall. No matter how much extra paste I added, or how tacky it got, the paper continued to curl.

My experience is that these papers usually get nice and flat when they dry, and look just fine. But the curling was so extreme in this case, and I didn’t want to hang around for three hours after I finished to check on the seams, so I decided to take another tac.

Since excessive moisture seemed to be the cause of the curling, I decided to paste the paper as if it were an unpasted variety. This is somewhat difficult, because the paste is thick (I didn’t want to thin it by adding water, which could encourage curling), and the paste activates the paste already on the back of the paper, so it makes something of a dryish, gummy mess, and it’s something of a wrestling match to get it to the wall and smooth out all the bubbles.

But the seams did stick down quite nicely. The paper had lots of ridges and bubbles from the paste , but those should disappear when the paper dries completely.
