Wallpaper and YouTube Don’t Mix

December 31, 2017


This West University mother of young children went to YouTube for some primers on how to hang wallpaper, and then, along with hubby, spent a 3-day weekend tackling the powder room redo project. They didn’t do a horrible job (first three photos), but there were some things that must not have been covered on YouTube.

First, and probably most important, the walls should have been primed with a product designed for wallpaper.

Second, seams should be butted, not overlapped.

Third, wallpaper should not be wrapped around the door moldings, but trimmed at the base.

Fourth, I’m not sure what’s going on with the cuts at the baseboard. I think the room had seen a number of redecorating efforts, and that the baseboards took a bit of a beating in the process, leaving a surface that wasn’t smooth and wasn’t willing to hold on to wallpaper.

I stripped off their wallpaper, patched bad spots, sanded the walls, then primed with Gardz, a penetrating sealing primer that bonds together porous surfaces and that is also a good base to hold wallpaper.

The rest of the photos are of the room after I hung the new paper.

This product is a pre-pasted, paper-backed, solid vinyl material. It happens to be one of my least favorite kinds of wallpaper. The homeowner chose it because she has young children and the vinyl is reputed to be more water-resistant and durable than other types of wallpaper. If she had consulted with me before she bought her paper, I would have steered her in another direction.

It’s true that the vinyl surface is resistant to water, and it’s more resistant to stains than a paper-wallpaper. But that doesn’t make the product wonderful.

The main problem is the paper backing. This stuff is not horrible, but it does have a reputation for curling a tad at the seams (do a search on my blog for previous posts). Humidity (such as in a bathroom with showering) can cause increased curling at the seams. Any water that falls on a cut edge of the paper (along backsplashes, seams under hand towels, etc.) can wick into the paper backing and cause it to expand, which will cause the seams to curl.

To reduce the potential for seam curling, I used a special pasting process (rather than following the manufacturer’s instructions). And I ran a bead of caulk along the top of the backsplash (see 4th photo – the caulk will be clear when it’s dry) to prevent splashed water from wicking up under the wallpaper.

My trim cuts along the baseboard looked better than the homeowners’, but I still felt the baseboard was compromised somehow and that wallpaper did not have a good surface to grip ahold of. So I ran a bead of caulk along the top of the baseboards, too.

This wallpaper is by Exclusive Wallcoverings, a British manufacturer. It is a faux grasscloth, and, unlike true grasscloths, it is pretty water- and stain-resistant, and it has a pattern that can be matched. In fact, the close-up photo above shows a seam – and I’ll bet that you can’t find it! The pattern number is FD44143

Next time around, when a mom has concerns about her kids touching or splashing the wallpaper, I would suggest she consider one of the newish non-woven products. Or, better yet, a scrim-backed (woven fabric-backed) solid vinyl product, such as something from the Thibaut brand Texture Resource line, particularly Volume 4. Everything in that book is beautifully textured and realistic, and virtually indestructible. Do a search here to see my previous posts.

Mildew!

December 13, 2017


You can clearly see the mildew on the wall that was revealed when I removed the wallpaper. It shows up as the black rings / circles.

The mildew was caused by moisture trapped in the wall by both a leak in the roof or siding, and a leak from a bathroom that crept under the floor – compounded by being trapped inside the wall by a solid vinyl wallpaper that would not breathe or allow air to pass through. Another reason to avoid paper-backed solid vinyl wallpaper.

Note: This issue was with mildew. Mildew is not nearly as dangerous as mold. Still, the homeowner took the contractor’s advice and had the drywall completely removed and replaced.

Peeling Paper Caused by No Primer Underneath

These wallpaper jobs are failing, mostly due to the fact that the previous installer did not prime the walls before hanging the paper.  With no primer, the walls are porous and will suck paste off the paper, leaving little to hold the paper on the wall.   Bathroom humidity has exacerbated the problem.

The top photo shows a paper-backed solid-vinyl paper, which are usually pre-pasted and lower-priced.  These are particularly bad for humid areas, because the paper backing tends to absorb humidity, expand, and push away from the wall.

The striped paper is a paper, which usually perform well and hold tightly to the wall even under humid conditions.  But with no primer to seal off the thirsty wall underneath, the paper has nothing to grab ahold of and is curling away from the wall.

In fact, when I went to strip the paper, it came off in whole sheets with just a gentle tug.  I had the entire bathroom stripped in, literally, about two minutes.

Before hanging the new paper, I will be sure to prime the walls.  The last photo (bottom row) shows two of the primers I will use.  The Pro 977 works on walls that are clean and have been previously sealed.  The Gardz is a penetrating sealer that is good for porous walls like flat paint, new drywall, or newly skim-floated walls.  It will also work on walls that have a bit of residual wallpaper paste because it seals it and makes it inert.

 

Mildew Found Behind Wallpaper

I removed a strip of paper-backed solid vinyl wallpaper from the wall over a shower in a room used by two teenagers.  The type of paper (one of my least favorites), the humidity from the hot and heavy shower usage, the  lack of primer used by the previous installer, and an exterior wall that most likely had some moisture problems, all added up to a recipe for mildew.

I used bleach and then another mold / mildew product to kill and remove the mildew, then went over it with an oil-based stain-blocking sealer called KILZ.

Over the KILZ, I added a coat of wallpaper primer.  The two primers that I use most are the large cans in the last photo, and they each are used for different circumstances.

 

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.

Stripping Off The ’90’s To Reveal – The ’70’s

July 20, 2017

Today I stripped paper off the walls of a typical entry in a typical ’60’s / ’70’s-era home.

The paper I removed was a pre-pasted, paper-backed, solid vinyl in a striped design. This is a typical pattern, and a typical type of material, for that time.

Under it was the original paper from when the home was built in the ’70’s. If you remember, that was back in the days of Harvest Gold, Avacado Green, orange, and Flower Power. This vintage paper has three out of the four!

After all these years, and despite having been covered up by the vinyl wallcovering, the orange paper was in perfect shape – tight to the wall, and brilliantly colored. The vinyl paper, on the other hand, was curling at the edges and was discolored.

This is partly due to age, but mostly due to having been improperly installed… previous installer did not remove the old wallpaper, and did not prime the walls, plus these pre-pasted, paper-backed, solid vinyls are just not good papers.

This home is in the Kirkwood / Briar Forest area of Houston.

Pouched Seams in Solid Vinyl Wallpaper

June 27, 2017

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.

Wet Stripping and Dry Stripping Old Wallpaper

I hung these papers 15-20 years ago. Still in perfect shape, too, I might add. 🙂

The homeowners are moving, and are trying to make the house as neutral as possible before it goes on the market. So the child-friendly lime green wallpaper had to go.

In the top photo, I am stripping a paper-backed solid vinyl paper. It is considered a peelable paper. These are pretty easy to get off, if you are patient. You peel off the top plastic printed layer, which usually comes off in large pieces. That leaves the tan paper backing stuck to the wall, which you can see as a “V” in the upper center of the photo. To the left of that area, I have wet the paper with a sponge and hot water, so it has turned darker tan. Once the water reactivates the adhesive, this backing will peel away from the wall easily; or it may need to be gently scraped off with a stiff 3″ putty knife. This process is pretty easy on the wall, and leaves little damage.

The second photo shows a thin paper wallpaper coming off by simply pulling on it. This is what is called a strippable paper. Interestingly enough, this paper was most strippable up high, where humidity from showering would have collected. Even strippable papers don’t always come off in one piece, and when they do, the process can put too much stress on the wall, so you might get pieces of the primer or underlying surfaces pulling off, too. To minimize damage to the wall, these papers can also be removed in the 2-step process outlined above. Since they are thinner, it’s a little harder to get the top inked layer off. But if you wet the surface first, which seems to make it stronger so it comes off in larger pieces, and then use that stiff 3″ putty knife to gently get under the top layer, and proceed as above.

Of course, what is under the paper has to do with it, too. In this case, my wonderful primer oil-based KILZ Original has provided a strong and water-resistant surface that sticks tightly to the underlying wall, and that let go of the wallpaper with no damage to the walls.

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

February 4, 2017

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.

A Whole Dining Room’s Trash In One Neat Roll

June 18, 2016

I like to make a game of seeing how long I can go without using a trash bag. Well, it’s been weeks, maybe months.

Today I was stripping off a paper-backed solid-vinyl wallpaper. The top vinyl (plastic) layer of this type of paper usually pull off in large pieces, even full-length strips. That’s what happened today. So I laid those out on the floor.

As I soaked the paper backing, it also let loose from the wall and came away in large, intact strips. I layered those on top of the vinyl sheets already on the floor.

Once all the paper was off the wall and stacked on the floor, all I had to do was to roll it all up into one neat package.

It’s amazing how large the dining room is, yet how small is this roll of recovered wallpaper.

Off to the trash bin you go. No trash bag required!

(Note: This wallpaper was made of vinyl and is not recyclable … when I have scraps of paper wallpaper, it goes into the recycling bin.)
