Contractor Patches On Top Of Wallpaper – Bad Idea

February 19, 2019


This home experienced a water leak, and the bottom 2′ of drywall had to be cut out and replaced. When taping-and-floating in the new drywall, the contractor didn’t bother to remove the existing wallpaper, but put his smoothing compound right over it. This is bad enough if the old paper is paper, but this wallpaper is vinyl – something you really don’t want buried under layers of joint compound and new wallpaper.

Vinyl is shiny, and few materials will stick well to it over a period of time. It is also thick, and that increases the likelihood that seams will pop up, even if they are buried under this “mud,” as we call it.

So I took a razor and cut above the contractor’s patch. Then I stripped off all the wallpaper above the patch. This left a difference in height between the patched area and the newly-stripped area, which would create a visible ridge under the new wallpaper. So then I took my own smoothing compound (joint compound) and floated over his patch and the now-bare wall, to eliminate any uneven areas.

Waited for it to dry, sanded smooth, removed dust, primed with Gardz, and finally was able to hang the new wallpaper.

This took a LOT more time than I originally planned for this job, but it was worth it to keep vinyl wallpaper from being underneath the new paper, and to prevent any bumps or irregularities from showing under the new paper.

Don’t Let Your Toddler Handle a Sharpie!

February 11, 2019


So the little girl was innocently playing with an ink Sharpie, and, well, the wall along the bottom of the stairway just happened to get marked up. (Unfortunately, my “before’ photo got lost somewhere.) This is very expensive wallpaper, and, unfortunately, was the first thing you see when you enter this West University home.

I was there to hang paper in the nearby powder room. But every time I walked past this stairwell, the ink marks just kept bothering me.

So, with the homeowners’ go-ahead, I decided to fix it.

First, we checked to be sure there was enough left-over wallpaper. Thank goodness for boxes stashed in the garage apartment!

I didn’t want to strip off the original wallpaper, for fear of scoring the wall and causing seams to lift. So the original wallpaper was left intact.

Then the ink had to be covered with a stain blocker, to prevent them from bleeding through the new wallpaper. I used oil-based KILZ Original. Two coats.

Next, because wallpaper paste will no longer stick to oil-based products, (due to EPA-required changes to the formulas), I primed the whole area with Gardz.

Because it’s not a good idea to have a seam fall on top of a seam, at this time, I placed a strip of seam tape (special stuff made by a colleague of mine) so that it bridged the gap between the two seams of the original wallpaper. The Gardz sealer / primer melded everything together.

Then I took the left-over wallpaper and found the corresponding pattern to match the pattern on the wall. I used a scissors to cut around this design. Because this repair fell on a seam, it required two strips of paper, one on either side of the seam.

Then I pasted the wallpaper patches, allowed to book and sit, then appliquéd them to the wall.

I was surprised at how stretchy and wrinkly the wet wallpaper was. I was glad that I was only doing two 18” high patches – I felt sorry for the guy who had hung a whole 2-story staircase and hallway of this stuff.

Bottom line – the finished patch looked fantastic. You could not tell that there had been any errant marks on the wall.

Here is a link to the wallpaper pattern. It is called Zumba ZigZag. https://www.fschumacher.com/item/5003300

White “Woods” Wallpaper Wakes Up A Dark, Dated Powder Room

January 19, 2019

OK, so my original whole-room photo of the “before” powder room didn’t take. But in the top photo here, at least you can see the dark color that the windowless room was covered with. Actually, this faux-finish pattern and dark color was a good look for back in the ’90’s when this townhome in the Briargrove / Tanglewood neighborhood of Houston was built.

But the homeowner now wanted a brighter room; she was leaning heavily toward black & white, with some hits of red tossed in.

I stripped off the old vinyl wallpaper (those photos didn’t turn out, either! 😦 ), then patched areas where the old paper had pulled paint off the wall, sanded smooth, and then primed all surfaces with Gardz.

The homeowner is completely in love with the new paper and the new, bright powder room. She will accent with a mirror in a wide black frame, and with some custom-painted artwork that will incorporate touches of black, white, and red.

This wallpaper is by Cole & Son, a British company. It is a very popular pattern called “Woods.” It’s on a non-woven substrate, which has a fiberglass component to strengthen it; it is designed to strip off the wall easily and with minimal damage to the wall, when it’s time to redecorate It is a little more cleanable than a paper-wallpaper.

It was bought from my favorite source for good quality, product knowledge, expert service, and competitive price – Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

Animal Blocks in a Baby’s Room

December 25, 2018


A new baby will soon be welcomed into the home of this young couple in the Houston Heights neighborhood called Norhill (or Woodland Heights). Mom wanted something gender-neutral, and found this colorful and adorable shapes-and-animals-in-blocks print on line at Lulie Wallace.

This went on just one accent wall of the room, but it is tame enough that it would work OK if put on all four walls.

I skim-floated the walls first, to smooth out the light texture on them, then followed with a primer coat of Gardz.

This wallpaper is a bit atypical, because it is pre-pasted, which means it comes with a thin layer of paste on the back that you activate with water (instead of having to roll paste on the back of every strip). I do like the pre-pasted papers. I do roll a light coat of paste on the wall, to augment the manufacturer’s pre-paste.

Another dissimilarity is that the paper comes packaged in individual strips, rather than traditional rolls with several strips rolled up together.

Even more unusual is that the strips were meant to be overlapped, instead of butted together. Overlapping the seams creates a vertical ridge under the paper which is somewhat visible. You also have to have an adhesive that will stick to the acrylic coating on top of the paper.

There are some good aspects to overlapping seams. For one, this makes for a very strong bond. For another, it takes stress of drying and shrinking paper off the seam and distributes it across that 3/4″ of overlapped area. In this 80-year-old house, with it’s many layers of paint with a history of not sticking to each other, this is important, because it greatly reduces the chances of the tension on the seams causing the paint layers to come apart, which would cause gapping at the seams. See previous post.

Another positive feature about overlapping the seams, and how that worked with this particular pattern, is that, in this 1930 home, with its unlevel ceiling and floor and its greatly-out-of-plumb walls, I was able to manipulate the strips of wallpaper so that they looked straight and plumb – even though they were actually hung quite off-plumb.

This wallpaper pattern is by Lulie Wallace, and was bought on line.

Wall Sealing Whoops

September 26, 2018


Today I prepped a room where the drywall had been badly torn when the old wallpaper was stripped off. This happened because the original installer hung the wallpaper directly on the drywall, with no coat of paint or primer to protect the drywall.

Before I could smooth the wall surface, I had to seal the torn drywall, because moisture on the torn areas would cause the brown paper to bubble. I rolled on a heavy coat of Gardz, a water-thin, penetrating product that is designed to soak into the porous material, bind everything together, and dry hard. It is supposed to dry inpenetrable by water.

Once it was dry, I skimmed over it with joint compound (which will be sanded smooth later).

As you can see, the Gardz failed to do as claimed, and it allowed moisture from my smoothing compound to seep through it and enter the torn paper of the drywall, which then expanded and bubbled. I’ve got a big mess on my hands!

Tomorrow, when everything is dry, I will sand smooth. Usually bubbles like this dry out and then sand flat. But the large loose areas have me a little worried. They may still be loose and bubbled, and they may swell again when the wall is given its final coat of Gardz.

I may end up having to cut out some loose areas, refloat, and reprime.

Not good, because this could add a full day to this job, and because there could potentially still be unstable areas under the surface. Never good to have an unsecure surface under your wallpaper.

Hoping to Rectify Failure (Humidity Causes Poor Seams)

August 24, 2018

Humidity is the great enemy of wallpaper. In addition, the lower-end, pre-pasted, solid-vinyl papers with the gritty manila paper backing are not a good choice, in my opinion, in any room, but particularly not humid rooms like bathrooms. This house on the beach with irregular climate control spelled double trouble.

This home on Pirate’s Beach on Galveston Island (south of Houston) was on the beach, so was exposed to lots of humidity. In addition, because the homeowners use it only sporadically, they turn the air conditioner off or set it to a run less while they are away. This means that the home fills up with humidity. And even when the A/C is running, air circulation in this room is poor.

Metal elements such as the light fixture and screws holding things into the walls were rusted. Mildew was found behind some sheets of wallpaper. And the wallpaper itself was curling at the seams – a result of the paper backing absorbing moisture from the air, expanding, and forcing the vinyl surface to curl backward at the seams. (Read more about this on the page to the right about vinyl wallcoverings.)

Another factor for the poor performance of the original vinyl wallpaper was that the walls had not been primed, but the installer put the vinyl paper on top of new drywall. And nothing was done around the shower to protect the paper from splashing water.

I stripped off the old vinyl wallpaper, washed the walls with bleach to kill the mildew, and primed with the penetrating sealer Gardz. Once the new paper was up, I ran caulk along the top of the vanity backsplash, and all along the shower and tub, to prevent splashed water from wicking up under the paper.

The new wallpaper is a thin non-woven material that is “breathable.” No wallpaper is going to hold up under very humid conditions. But this one has a much better chance of staying nice and flat for many years.

The new wallpaper is very similar in appearance to the original, and keeps with the beachy feel of the home. It is by Brewster, in their Chesapeake Bay collection, in the Easy Walls line, and is reasonably priced. It is a pre-pasted material. I did augment the manufacturer’s paste with a .

In the photos, the paper looks blotchy. That is because it is still wet; it will be nice and white when it’s finally dry. The drying time worries me, though, because after six hours, even some parts of the first strips were not dry. This is a real indicator that the room has some serious humidity and air circulation issues.

Leopards Walk the Room Right

August 19, 2018


I’ll be the first to admit – I love a darkly decorated room. But this all-black powder room in the home of a young couple in the Heights neighborhood of Houston was not making the grade. With shiny black paint on all four walls, there was nothing to define the room. You literally could not even see where one wall ended and another began. And the work had been done poorly, with zillions of bumps and bits of stuff stuck in the paint.

My first task was to use Liquid Sandpaper to degloss the shiny paint. Then I skim-floated the walls to smooth over the irregularities. Sanded smooth, wiped off the dust with a damp sponge, then primed with the penetrating sealer Gardz. Sorry, no pic of the prepped walls.

The new homeowner was fine with the dark idea, but she wanted something fun and a little sassy, that would wake you up when you walk into the room. These marching rows of leopards do just that!

The new wallpaper is still dark. But not quite as dark. And because it has pattern and some variations in color, you can easily see the corners, and each individual wall. The room is no longer stark and oppressive, but warm and fun.

This wallpaper design is called Leopard Walk, and is by Cole & Son, a British company. It is a thin and flexible non-woven material with a vinyl surface that will resist splashes and stains better than most papers.

Birds for the Bold of Heart

August 18, 2018


A lot of clients tell me they love birds, and are seeking wallpaper patterns with foliage and birds. (Do a Search here (upper right corner) on the word “birds.”) Most of those are what you would call sweet patterns. This design, on the other hand, can only be called BOLD.

The homeowner, also in the Houston Heights, is the sister to the guy mentioned in yesterday’s post. As you can see, they share an adventurous taste in decorating!

Although the pattern has a lot going on, it doesn’t feel busy, even in a powder room, partly because of the fairly homogenous color scheme, and also because of the all-over placement of the design elements. Besides, who can resist those intense faces? My favorite is the owl-like bird staring you dead in the eye.

The walls in this new home were heavily textured, so I had to smooth them first (see top photos) and then prime with a penetrating sealer called Gardz.

This wallpaper pattern is by Clarke & Clarke, a British company. As are many British products, it is printed on a non-woven substrate and is quite durable. It can be dry-hung using the paste-the-wall method – but I prefer to paste the paper. It was a little easier to work with than yesterday’s paper, being thinner and softer and less prone to creasing.

Gently Updating a Sharpstown Dining Room

August 10, 2018


A few years ago, I papered the entry of this mid ’60’s ranch style home in the Sharpstown neighborhood of Houston. Now the homeowners were ready for an update to their dining room. As is typical of the homes from this era, just the top of one wall in this room was papered. The top photo shows the original wallpaper – still in perfect condition.

There were complications to getting the paper off the wall, so I elected to skim-float over it, sand smooth, and then prime with the penetrating sealer called Gardz.

The third shot shows the finished wall. The design has a metallic sheen to it, and an interesting pattern of color that changes subtly as you move around the room.

The homeowner is kicking around the idea of painting the bottom of the wall a darker aqua color, which will balance the wall nicely.  If they get brave enough, they might paint the whole room a soft aqua.  🙂

Contractors and Painters Should NOT Prep Walls for Wallpaper

July 14, 2018


This home in the Meyerland neighborhood of Houston was flooded during Hurricane Harvey, and has been redone, and is now ready for final touches, like decorating, i.e. – wallpaper!

The first three photos show how the contractor left the walls. It’s hard to conceive how anyone could think these walls are “ready for wallpaper.”

What you are looking at is where the contractor ripped off the top, inked layer of the original wallpaper. Most of them don’t realize that there is a backing layer of paper that is left on the wall, that should be removed, too. Simply soaking this with a wet sponge will reactivate the paste and allow the paper to be removed easily, and with no damage to the wall (esp. if there is a good primer underneath the paper). Read my page to the right “How to Strip Wallpaper” to see how this should be done.

Instead, this contractor left the paper backing on the wall. Some of this porous backing is exposed. Other areas have been covered with the paint that was used on the woodwork. This solvent-based paint “raises the grain” of the surface it’s applied to – see all the hairy fibers from the wallpaper backing that have gotten stuck in the paint and raised up? Some of them are more than 1/4″ high. They create a gritty feeling on the surface, like really coarse sandpaper.

The surface is uneven, and the bumps will show under the new paper. The unevenness also means that areas of the paper will not be able to contact the wall, so there will be gaps and air bubbles and poor adhesion. The backing of the original wallpaper has been exposed, and when new, wet, pasted wallpaper gets placed on top of that thirsty paper backing, it will absorb moisture, expand, and bubble.

I had three missions. 1.) Seal the surface 2.) Smooth the surface 3.) Prime with a wallpaper-appropriate primer.

I rolled on a coat of the penetrating sealer Gardz to seal the surface, so that my following treatments would not cause the paper backing to bubble. When that was dry, I skim-floated the wall with a coat of joint compound. In the areas where the hairs were 1/4″ high, the skim coat was pretty thick, and took a good while to dry. Once that was dry, I sanded it smooth, then vacuumed the dust of off the floor, used a damp sponge to wipe residual dust off the walls, and then followed up with another coat of Gardz. It will soak into the joint compound and dry hard, forming a stable surface for the new paper to adhere to.

The last photo shows the wall once I finished.
