Re-Doing Accent Wall in Powder Room

The homeowner’s contractor’s guy hung this accent wall in an under the stairs powder room . He did a good enough job. But there were some bubbles / wrinkles . Depending on where you’re standing in the room, and where light is coming from, the bubbles were somewhat noticeable , even with this busy patterned wallpaper . It bugged the homeowner , and she wanted it to look better.

Dry-stripping the wallpaper resulted in this. The paper came off in an intact sheet, as the mfgr promises. But it took some of the primer along with it.
Let’s examine this. It’s a good thing, at least, that the previous installer used a primer, and hopefully one made for use under wallpaper. But, to be honest, a wallpaper primer is designed to let go of the wallpaper when you start to strip it off the wall. So maybe this is just paint, or a paint primer .
Second, I have a suspicion that, after skim-floating and then sanding the wall to smooth it, dust was left on the wall , and then trapped between the wall and the primer. That’s a likely reason why the primer / paint pulled away from the wall so easily. Nothing sticks to dust! So it’s imperative that, after vacuuming , you take a damp sponge – rinsed frequently – and wipe down the entire wall, and then let dry , before priming. The primer also has to dry completely, before wallpaper goes up.

I switched to wet-stripping the remaining wallpaper, and had less damage . But was still left with a wall with lots of irregular and un-smooth areas . So to prepare it for wallpaper , I first sealed loose or dusty areas with GARDZ , which is a penetrating and hard-drying sealer for torn drywall or other unstable surfaces . It’s pretty cool stuff.
After that dried, I applied a very thin skim coat of joint compound (which we call mud ). Once that was dry, I sanded smooth , vacuumed , wiped off residual dust with a damp sponge, let dry, and then primed with Roman Ultra Prime Pro 977 and let dry.
Here’s what it looked like when I was done with the prep .

And here it is with the new paper up.

This single wall was a bit of a challenge, for many reasons. For one thing, we really didn’t have enough paper. Luckily, the previous guy had kept the left over scraps, and I did need to use some of those. It also was OK to mis-match the pattern when necessary, as the design is very forgiving. The rounded bull-nosed edges around and over the window are a PITA. This pattern was forgiving in that respect, too, as well as the layout of the area over the window. There were also some printing defects , which will be addressed in a future blog post .
Oh – and I, also, got bubbles ! In fact, I hung this same brand a few weeks ago and got bubbles then, too. Some I got rid of by making a tiny cut with a razor blade and then pushing the air out with my plastic smoother . But, usually, with these pre-pasted materials, once they get good and dry, small bubbles dry flat and disappear. Not sure why the other guy had problems with this. But I will say that the bubbles were larger than typically show up with these papers.

Close up.

The pattern is called Brownstoner , and is by Flavor Paper . I am not a fan of their vinyl products, and definitely not their peel & stick . But I do like their EZ Papes , which is a pre-pasted material . Not crazy about the bubbles, though.

The home is in the Eastwood neighborhood of Houston .

Cool Patch to Repair Hole in Wall

The homeowner had removed a toilet paper holder that was recessed into the wall , leaving a 5″ x 5″ square hole. She said it was OK with her if I just put the wallpaper over the hole. It is a thick non-woven, and would have held up OK. Thing is, this trick works better for smaller holes, and I routinely do it with land-line phone jack holes. But this hole was larger, and you’d likely see an indented area. Also, if a seam fell on that hole, there would be no way to hold the paper together.
One of my customers a couple of weeks ago fixed holes left from moving electrical boxes for wall sconces , and used this. I happened to have purchased it at Sherwin-Williams just the day before, and it was a success.
It’s a light-weight metal mesh grid with a fiberglass mesh tape sort of “wings” on each side. The wings are self-stick, and hold to the wall.

I didn’t think to get a picture of the hole before treatment, but here it is after the patch plate is in place, and after I’ve skimmed over it with joint compound. I let that rough patch dry overnight, then did a fine-tune skim-coat the next morning, which is what you see here.

When that was dry, I sanded, wiped off the dust, and primed. I’m very impressed. No sucking in or pouching out, and it’s flat and solid. Oh, and a wallpaper seam did fall over it, so good thing I went the extra step to use this patch.

Spray Can Texture

I’m getting ready to skim-float this accent wall in a master bedroom , to smooth the textured wall .  The texture on the wall looks a little odd to me.  Also, it is more concentrated in the center of the wall , and less so as you get close to corners and window moldings .
This is leading me to think that this texture didn’t come with the house .  When homes are built and texture is wanted, the painters or drywall guys come in with spray equipment and shoot the joint compound onto the wall.  This gives a pretty uniform coverage , and also coats every surface, up into corners and molding.
Not sure, but I think this one I’m working with might be the after-market kind that you can buy in a spray can from Home Depot .  It does seem pretty uniform, too.  
You can do a search here to read more about the skim-floating / skim-coating process , and smoothing textured walls , to provide a smooth and attractive surface for the new wallpaper . 

Skim-Floating to Smooth a Textured Wall

Wallpaper is to go on the top 2/3 of the walls in this large dining room. But the walls are textured, and that texture will show through the new paper. Which looks pretty bad , IMO , especially since most the design is plain white background. So here I am applying a skim-coat by skim-coating / skim-floating the wall to smooth over the texture.

Close up. A lot of people use a wide broad knife or drywall taping tool . But I prefer the control I have using this trowel . There will be ridges and valleys and imperfections . But tomorrow, when the smoothing compound is dry , I will sand everything smooth . I have to say, I’m pretty darned good at smoothing walls . 🙂

I like to use the Plus 3 Joint Compound by the Sheetrock brand. It’s much easier to sand than the standard joint compound . Do NOT use the ” quick set ” version – coatings such as primer , paint , or wallpaper don’t like to adhere to this stuff . It’s made for small patches , not covering entire walls. BTW, for short, we simply call this ” mud .”

Once the walls have been sanded smooth , all the dust vacuumed up, and residual dust wiped off the walls with a damp sponge , then I will apply my favorite primer, Roman Pro 977 Ultra Prime , made specifically for use under wallpaper .

Sneaky Snaky Dining Room Accent Wall

Beautiful symmetry …

But look closer – those intertwining lines aren’t fronds of vegetation – they’re snakes !

The wall before. It’s a mid-century home, but the drywall here is new. Per my request, the contractor left it taped and floated , but not painted or covered with any coating .
I had planned to simply prime this wall. But after examining it more closely, the surface was a little grittier than I like. So I ended up applying a very light skim-coat and sanding it smooth .

Here the smoothed wall has been primed with Roman Pro 977 Ultra Prime .
I’m plotted out the center of the wall and am using my laser level to ensure that the design in my first strip falls right along the center, and also is nice and plumb .

My work table with two strips of wallpaper . Spoonflower packages its wallpaper differently from other companies. It comes in widths of 24″ and lengths of your choice of 3,’ 6,’ 9,’ or 12.’
Get their Pre-Pasted Removable Smooth option, which is water-activated , and is wonderful stuff.
Do NOT get the Peel & Stick , nor the Traditional Pebble . The P&S and the Traditional are both very difficult to work with, and can lead to bubbles and creases on your walls , plus cause damage when the wallpaper is stripped off later.
Back to the photo – the blue cube thing in front is my laser level , shooting its red line at the wall.

I’m using this blue plastic tape on the edge of this strip of wallpaper. This will prevent paste from getting onto the wall or ceiling.

The accent wall stops in this left hand corner, so I need to trim off the excess. But I don’t want to get paste onto the un-papered wall. Paste can cause the wall paint to crackle and flake off.
So here you see how the blue tape is keeping paste off the wall. Once I finish trimming, I’ll check the back to make sure all of the blue tape has been removed. Any areas where the blue tape might be still on the back of the wallpaper , the paper won’t adhere to the wall .
This tape is available to paperhangers / installers . If you’re interested, shoot me an email wallpaperlady@att.net

Another thing about Spoonflower , the seams are meant to be overlapped, by 3/4″ . Note that this does create a ridge that runs vertically the length of each seam. In the grand scheme of things, this isn’t very noticeable.
Actually, there are advantages to overlapping seams in this manner. No worries about white substrates showing at the seams, nor the paper shrinking and leaving gaps at the seams.
Also, in case of unstable walls that might come apart ( delaminate ) under the tension of the drying / shrinking wallpaper, overlapping disperses the tension and helps prevent wall failure.

This pattern is called Serpents and Apples and is by Spoonflower . Spoonflower has a lot of cute designs , and also a good number of fun avant garde patterns like this one.
The homeowners have some other non-typical décor that will meld perfectly with this wallpaper. Think life-sized skeletons .
… Notice how that light fixture hanging in the center of the wall kinda looks like a skull ? …
The home is in the Oak Forest area of northwest Houston .

Stuff Doesn’t Wanna Stick To Slick

Tomorrow this breakfast area wall will get wallpaper. Today is prep day.

The wall has a very heavy texture, plus some issues with previous patches in areas, probably due to drywall cracks. I need to skim-float over all this to smooth the surface.
In addition, the current paint is quite glossy – and this can present a problem for the smoothing compound to adhere to it properly.
So I want to prime over this gloss paint before I skim-coat the walls. The primer has to both stick to the gloss paint and provide a base that the smoothing compound will adhere to.

Another issue is that I won’t be using this every day, so keeping it shaken up and useable was a consideration. I looked high and low for an appropriate primer. Finally I snapped that the Roman Ultra Prime Pro 977 that I use under my wallpaper jobs checks off all the boxes … It sticks to just about anything, and it dries nice and flat / matt so any topcoat (wallpaper or smoothing compound) can grab ahold and stick, I have it in my van all the time, and I use it frequently enough that it’s always mixed up and ready to use. To top it all off, it dries in less than an hour. Voilà!
This stuff can be tricky to find. Sherwin-Williams used to stock it for me, but became unreliable. Now Murphy Brothers on Bissonnet (Houston) gets it just for me.

Besides dropcloths on the floor, here I’ve tacked strips of thin paper dropcloth material along the wainscoting (I also do this along baseboards) to keep any drops or roller splatters from marring the homeowners’ floor and moldings.

Here it is applied. Since my goal is to cover and eliminate the glossy paint, and then provide a base for the smoothing compound, this coat doesn’t need to be opaque or cover the wall evenly.
Tomorrow we’ll see how the wallpaper turns out!

Fast-forward … I’ve floated the wall and sanded it smooth. Compare the smoothness to the “before” picture at the top.

Kill Point Over Door, Ridge, More

After you’ve hung wallpaper on all the walls in a room, the point where your last strip meets up with the first strip is called the kill point . This virtually always ends up in a pattern mis-match. That’s why you engineer to place it in an inconspicuous place, such as behind a door.
This powder room, though, had no hidden corner or handy door. That meant that I would have a pattern mis-match a full 5′ high, to the left of the toilet you see here. I prefer to have the pattern match in a corner like this. As you can see – it does. I will explain how I accomplished that.

I decided to place the kill point over the door. Even though this space is 2′ high and a mis-match might be noticeable, not many people are looking up over the door, so it’s a better choice than in a 5′ or 9′ long corner.
The dark smudges on the wall in the photo are where I’ve spread paint, to prevent white walls from peeking out, should the dark wallpaper shrink as the paste dries.

Here I’ve positioned the strip on the left. This leaves a gap of about 3″. Once I match the new strip up to the piece on the right, its pattern will not match perfectly with the strip on the left.

Now I’ve positioned both strips, and the one on the right is overlapping the one on the left.
Here’s an idea of what the pattern mis-match will look like. To be honest, it’s not all that bad, with this busy pattern and being up over the door. Still, I thought I could make it look better.
I’m going to do a double cut , which is our installers’ fancy term for a splice. I’m going to cut through the two strips, splicing them together, cutting along the vertical foliage elements, to minimize cut-off motifs and to disguise the splice.

When double cutting on the wall, it’s really important that you slice through the two layers of wallpaper only , and not cut into the primer or wall surface beneath. This is because, if the wall surface becomes scored or compromised, when the wallpaper paste dries and the paper shrinks and pulls taught, it can put tension on the wall surface. If the surface is not intact, it can give way and actually come apart ( delaminate ), resulting in wallpaper that comes away from the wall – and there’s nothing beneath it to paste it back to.
I’ve blogged about this before, so do a Search here to learn more. It’s important!
Anyway, to protect the wall beneath where I will make my splice cut, I’ve placed three layers of scrap wallpaper, to pad the wall. I figure I can cut through the two top layers, but not all five.
Note that three layers of non-woven material have some thickness, and can “throw off” the splice cut and prevent the top two strips from fitting together perfectly. In this case, the paper is flexible enough that I’m not worried about that particular scenario.

The strips are in place, and I’m ready to make my cut. I prefer to use a single-edged razor blade held in my fingers, rather than a blade-holder. What’s most important is that the blade be brand new and spankin’ sharp!

Here I’ve made my cut and am removing excess paper from the right side of the top strip. Look carefully and you can see how my razor blade followed the contours of the vertical foliage design elements.

Here I’ve removed the excess paper from the left edge of the bottom strip. You can see they are poised to fit together nicely.

Before fitting the two strips back together, though, I’m examining the wall surface. Check the photo carefully, and you’ll see that I did, after all, score into the primer. 😦 The surface below is skim-coat that was used to smooth a textured wall – and another potential layer that may come apart when exposed to tension from the drying wallpaper.
Shoulda used a Boggess Strip. https://www.steveboggesspaperhanging.com/lexanpage.htm

One way to prevent the wall from delaminating is to put something over the compromised area, to distribute the tension of the drying paper and take it away from the cut wall. Here I’ve taken a scrap of wallpaper, which is a tough non-woven material, and carefully peeled the printed surface from the white substrate (no pic of that process). Now I have a thin material that I can use to pad the wall.
I’m using the black printed side facing out, in case the spliced strips shrink a little – anything peeping out will be black and not noticeable.

Here is the bit of paper in place, spanning across the cut on the wall.

Now I’ve smoothed the two top strips back into place. Since my double cut followed along the vertical foliage elements as much as possible, and because I cut around the gold flowers to keep them full and round, the pattern looks like it matches up just about perfectly.
But wait! … What’s that lump / ridge under the wallpaper, the full height of the seam? That’s my seam padding! Doesn’t look great.
I’m really surprised at this. The non-woven wallpaper material is thick. But that’s why I pulled the top and bottom layers apart, to make my patch piece thinner. I guess not thin enough. Once dried, this ridge is going to be obvious.
But, to be honest, this is up over a door where no one’s going to be spending much time looking. In addition, once I get my 100 watt light bulb out of there and replace the homeowners’ original, small light fixture, this bump under the wallpaper will be pretty much indiscernable.

Still, that lump was buggin’ me. Another invention from my colleague Steve Bogges to the rescue! Pictured is his seam tape , which was made specifically for this type situation. This is very thin – yet strong – paper tape that is used to bridge cut areas like this, and prevent tension from drying wallpaper from tugging at unstable walls.
The tape has a pre-pasted side (the gloss you see), and feathered edges, to make it less noticeable under wallpaper.

Hard to see, but here I’ve placed the seam tape over the cut wall areas

Now the two top strips have been smoothed back into place. Amazingly, no bump from the seam tape beneath shows. And the pattern mis-match is barely visible, too.
Win-win!
All that’s left to do is to wipe paste off the surface of the wallpaper. This overlapping and splicing does mean that wallpaper paste will get on the surface of the strip underneath. Actually, there is a way to prevent that, and it also involves products from Steve Boggess …
But … that’s a blog post for another day …

This pattern is called Peonies and is by Rifle Paper.

Fixing Drywall Damage From Where Vanity Was Removed

The powder room in this 1990’s home in the Houston Heights is being updated, and that means replacing the wall-to-wall vanity. Here the vanity has been ripped out. The areas where the backsplash was adhered to the wall have pulled the top surface of the drywall off. In addition, the plumber had to cut out a section of drywall in order to gain access to the pipes, so he can install the new faucet and handles. You can see the connections roughed in.

You can’t hang wallpaper over this mess. First of all, it way too uneven – all those bumps will show under the new wallpaper. And the outline of the ” trapdoor ” will leave a big square ridge under the paper. Thankfully, the plumber secured the panel with drywall screws – most plumbers just leave you with a chunk of drywall floating in space, or even just an empty hole.
Back to patching issues … in addition, the torn areas of drywall will absorb moisture from the wallpaper primer and / or paste and expand, creating bubbles that will show under the new paper.
I needed to fill in dips and gouges, even out high areas, and prevent bubbling drywall.

Gardz by Zinsser to the rescue! This is a penetrating sealer that soaks into porous surfaces and then dries hard, binding them together and creating a stable surface, as well as resisting moisture from water-based top coatings.

This picture doesn’t look much different, but here the torn drywall is a little darker, indicating that the Gardz has soaked in and dried. The surface is now ready for a skim-coat.
But first, the trap door needs to be addressed. I covered the cut areas with four strips of self-adhesive mesh drywall tape (no photo).
Then I went over everything (wall to wall) with joint compound (commonly referred to as mud ) (no photo).
Because of the thickness of the high and low areas, this had to be a thick coat of smoothing compound, and would take a long time to dry. So I went to the jobsite two days ahead of our install date, to do these initial repairs.
And – no – you can’t use quick set or hot mud or 5 or 20 minute mud to do these repairs. These products are intended for repairs of small areas. Top coatings like primers, paint, and wallpaper paste do not stick well to them. Don’t let a contractor sweet-talk you into letting him use any of these to smooth a large area of wall.

Here is the wall after my first, heavy, coat of smoothing compound. I use Sheetrock brand’s Plus 3.

The bubbles you see just left of center show that Gardz didn’t 100% do its job of sealing out moisture, as a little expansion and blistering has occurred. Not a biggie. These will disappear when the surface is sanded. There is usually not a problem with these re-appearing.

When I got to work two days later, the smoothing compound had dried. I sanded pretty smooth. Then vacuumed up the dust on the floor, and then used a damp sponge to wipe residual dust off the wall. This is important, because no coating will stick to dust.
The wall still wasn’t perfectly smooth, so I did another skim-coat. This was much thinner, so didn’t need a lot of time to dry. I used a fan and my heat gun to speed things along.
Once that was dry, I sanded it smooth, vacuumed and then wiped off all dust. Then rolled on my favorite wallpaper primer Roman Pro 977 Ultra Prime. I have the paint store (Murphy Brothers in central Houston) add a little blue tint, so I can see it when I apply it to the wall.
What a transformation! Now this wall is ready for wallpaper!

Crumbly / Unstable Wall Issues

Starting to strip wallpaper. You see the top, inked layer, the tan backing layer, and the white skim-floated wall beneath.

Wall surfaces delaminating at seams

Gardz, a penetrating sealer that binds surfaces together and dries hard.

My first idea was to just Gardz the lifted areas. The sealer is newly applied and still wet in this photo.

Gardz’ing the whole wall created a more stable surface. This doesn’t look much different from the photo above. But in actuality, the the Gardz has sealed and “locked down” the surface, as well as soaked into the material and sealed the inner layers as well.

Applying a skim-coat to even out the surface levels.

Once this skim-coat is dry, it will be sanded smooth.

The installer of the original paper did a good job of skim-floating the wall and creating a smooth surface. But he didn’t apply a sealer or primer. Thus, when I used water to strip off the old wallpaper, the moisture soaked into his skim-coat (drywall joint compound, a plaster-like substance, which we also refer to as “mud”). Some of the skim-coat came away from the wall,,, particularly in areas of stress, such as where the wallpaper seams had lain.

In fact, long (years) before I began stripping the wallpaper, many of the seams had started to pull away from the wall, taking inner layers of the wall along with them. This is because wallpaper shrinks as it dries, and that creates tension on the wall. If the wall surface is unstable, these layers can delaminate (come apart), and the result is an open seam with chunks of wall material stuck to it.

This can also happen over time, as temperature and humidity changes can cause the wallpaper and / or wall surface to absorb and then let go of moisture. All this puts stress on those wallpaper seams and on the layers inside the wall.

Besides these seam areas that let go, I had one wall where the entire surface came apart in a mottled effect.

Another factor is that the original skim-coat had been applied over a glossy paint. It’s hard for anything to stick to gloss. The guy probably should have rolled on a “bonding primer” before applying his skim-coat.

Of course, all that increases the time and materials needed, and ups the cost to the homeowner.

Gardz is a wonderful product that is designed to soak into surfaces and “bind them together.” It dries hard and is pretty water-resistant. It was originally intended to “lock down” torn drywall. But workmen quickly discovered that it would fix a whole lot of other surfaces – such as my delaminating skim-coated walls.

At first I thought I would just Gardz (we use it as a noun and as a verb!) the areas that were lifting. Once it dried, I intended to skim-float over these areas, sand smooth, and then prime the entire room with my usual wallpaper primer – Roman Pro 977 Ultra Prime.

But I realized that, even after I wiped down the walls with a damp sponge, they were still covered with powder or grit. This was powder from the layer of skim-coat, as well as residue from wallpaper paste. Neither my primer not wallpaper will stick securely to powder.

So I decided to roll Gardz on to all the walls, ceiling to floor.

Fifth photo – I was really pleased with the way the Gardz soaked in and drew all those layers together. There was no more power on the surface, and the inner layers of the walls were all pulled together.

To even over these vacant areas, and to create a pristine new surface, I skim-floated over the entire wall surface – all walls, floor to ceiling. See last photo.

Once that is dry, tomorrow morning, I will sand everything smooth. Next I’ll apply my 977 primer.

Then walls will be stable, and the surface will be ready to take on the new wallpaper.

From Textured to Smooth Wall Surface

Many homes in Houston have textured walls. In new homes in the suburbs, the texture is often really heavy – the so-called “Tuscan” look.

The texture will look bad under the new paper, plus it interferes with good adhesion. So it needs to be smoothed out before the paper can go up.

I use the process called “skim-floating” or adding a “skim-coat.” You can Search here (upper right corner) to find posts explaining this process.

And don’t pay your painter or handyman to do it – they don’t understand what’s needed for wallpaper. I’m many times better! 🙂

Here are before and after pics of a powder room I smoothed and prepped in the Bellaire neighborhood.

That second photo is enlarged many times – the wall is actually much smoother than the picture makes it look.
