Fixing Drywall Damage From Where Vanity Was Removed

January 20, 2022
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!

Cactus Patch Powder Room

January 5, 2022
I didn’t get a picture of the original dull, putty-brown paint, which did nothing for this space. Here is the room primed with my favorite Roman Pro 977 Ultra Prime, formulated specifically for use under wallpaper.
Sink / vanity area before.
Wow! This billowy cactus pattern makes a statement!
Tall! The ceilings in this home are over 10′ high. This very fluid, vertical design makes them seem even higher! Your eye just swoops up toward the ceiling! This back wall is what you see when you first enter the room, so I centered the cactus pattern on this wall.

I was also able to center the pattern on this sink / vanity wall. It will look nicely balanced when the mirror goes up. A new light fixture is coming, and will be installed where you see the round hole / electrical box in the wall.
Close up.
Milton & King is the manufacturer, and San Pedro is the pattern name. M&K makes nice wallpaper, and I enjoyed working with this. It’s a non-woven substrate, so you can paste the wall if you like – but I usually prefer to paste the paper. The surface felt like a thin, flexible vinyl – durable and fairly resistant to splashes in a bathroom. Their patterns often come as a 2-roll set, with an ” A ” roll and a ” B ” roll. It can be a little tricky to measure for these until you get accustomed to how they work. Further complicating the issue is that this design has a 51″ pattern repeat. In a nutshell, this means that, in order to match the pattern from strip to strip, you may have to cut off and throw away as much as 50″ (more than 4′ ! ). Thus, with these high ceilings and the long pattern repeat, instead of getting three strips from each 33′ long roll, I got only two. So a lot of paper went into the trash pile. It’s important to be cognizant of that and include the waste factor when calculating how much paper to purchase. Better yet – have the paperhanger figure it up for you!
These homeowners had already ordered their paper before I arrived for the initial consultation. After measuring and calculating, I told them to purchase one more 2-roll set.
Another odd thing is that at the end of the day, we ended up with two full unopened “B” rolls plus one full-length “B” strip,,,, that’s a total of five full-length strips. But we had only one 10′ strip left of the “A” rolls. This points out that, depending on the layout of the room, you can use more “B’s” than “A’s” or vice versa. I’m sure glad I made them buy that additional 2-roll set!
This new townhouse in the Heights neighborhood of Houston is home to a young couple. They will be married in a month or two. I had originally set their install date for a week or so before the wedding. I got a last-minute schedule change, they were able to get the room ready for me on short notice, and so I got their wallpaper up today,,, and they can spend the next months focusing on their upcoming special day!

Kitchen With Burst Pipe Water Damage Fixed and Finished

December 24, 2021
This kitchen in the Spring area of north Houston suffered severe water damage from burst pipes during the hard freeze in February 2021. Nearly a year later, they are almost finished with repairs, including new drywall on bottom of walls, new cabinets, new plumbing, cabinets, electrical, and more. Here you see the contractor’s repair work on top of some of the original wallpaper, which dates to the early 1980’s! It was a good brand, and the installer did a great job. For various reasons, I opted to leave this wallpaper in place, and so skimmed over uneven areas and then primed on top of it with Roman Pro 977 Ultra Prime.
The homeowner’s new choice is very similar to the previous paper, but with a more springy feel and a lot of upward movement. The area below the chair rail will receive another coat of paint to better define the correct yellow color. Or, the homeowner may switch to a green pulled from the leaves in the pattern.
This wall with the fir-down / soffit was a real bugger, for various reasons, and took me about four hours.
Looks so sharp against the white paint and tile!
The wallpaper was printed on a white substrate, so I ran black chalk along the edges of each strip, to try to prevent white from showing at the seams. Still, some of the strips shrank just a half a tad, and that did allow some white to show. This wallpaper is a non-woven material, which has a high polyester content, and is not supposed to stretch or shrink, so this is disappointing. Pasting the wall and dry-hanging the material would have probably helped. But the material was extremely thick and stiff, and plus the room had way too many turns and bends and angles, so pasting the paper made the most sense. These gaps are very minor, and only visible when viewed from straight on; from an angle you can’t even see them. On some papers, I can pull some tricks out of my bag and camouflage them. But with this non-woven material, don’t even try anything with paint, marker, chalk or anything else – it will surely stain the material.
The walls are smooth. The slight texture you see is the non-woven material. When an edge is torn, you can actually see the polyester fibers – a lot like fiberglass. This material is very strong, and is designed to strip off the wall easily and in one piece when it’s time to redecorate.
Manufacturer is Mind The Gap out of Transylvania (!), and the design is called Aquafleur, in the Anthracite color. The material comes as a 3-panel set, which they call one “roll.” The overall width of the A, B, and C panels side-by-side is about 5′, and the height is just under 10′. The height of the wall was less than 5,’ and the strips were nearly 10′ long, so at least 5′ was lost of each strip. Because the pattern was a mural type, rather than a typical repeating wallpaper design, even more paper was lost in working around the configurations of the room – for instance, a full 10′ strip would be needed to paper just one 9″ high strip above the door. So there was an incredible amount of waste – and this is a higher-priced boutique brand. But the lady of the house really loves it, and so she went with her heart.

Stripping Wallpaper

December 7, 2021
The contractor removed the wallpaper at the top and right side. Here I have begun pulling off the top layer of paper, to the left of center in the photo.

This shows how wallpaper can be stripped off a wall simply and without damage to the underlying surface. The keys are 1.) water and 2.) patience. Oh, and proper wall prep by the original installer.

First and foremost, don’t start yanking and trying to force the paper off the wall dry.

What you do is use a putty knife to lift an edge of the paper and gently pull off the top, inked layer. It should separate and leave the backing on the wall. In this photo, that’s the white paper. Kinda hard to see, because the wall is also white.

Once the top layer is off, you use a sponge dipped in a bucket of water to soak that backing layer. The idea is to reactivate the paste. Once the paste has wetted a bit, it will loosen and you can then gently pull it off the wall.

In most cases, it will strip off the wall easily, as you see in the photo.

It helps immensely if the wall has been properly primed before the paper went up. In this case, the original installer’s (me!) primer (Roman Ultra Prime Pro 977) held up to the stress of tugging the paper off the wall, and also prevented the water from penetrating through to the original surface.

Soft Jungle Mural for New Baby’s Accent Wall

November 19, 2021
The first installer was inexperienced, and left gaps at the seams, wrinkles, creases, mis-matched pattern, and even tears. The homeowners had their painter strip off the wallpaper, patch the torn areas of the wall, prime, … and then they had to purchase a whole new mural. Oh, and next they called me! 🙂 The painter was unschooled on wallpaper, too, so he just grabbed something off the shelf at Sherwin-Williams that had “wallpaper” on the label, and rolled it on. That particular primer, Pro 935, is meant to be used in different sorts of situations, and was too glossy and too tacky. I covered it with my preferred Pro 977 Ultra Prime by Roman.
Putting latex / water based paint over torn drywall will often cause the moisture from the paint to soak into the drywall paper and cause it to expand, which creates bubbles. These look bad under the new wallpaper. Here I have cut around one such bubble and removed the top layer. I will skim-float over this area, let it dry, sand it smooth, and then prime over it.
A whole wall’s worth of mural fun rolled up into one cylinder. They provided powdered paste – which I did not use, mostly because these tend to be too wet and can lead to staining on these non-woven materials. I did, however, take the paste home with me, because every now and then you run into a delicate wallpaper that requires this stuff – which can be hard to source.
I started hanging in the middle of the wall. Mostly because whoever measured forgot to add FOUR INCHES to both the height and the width. Instead, the manufacturer added only one scant inch at each side. This didn’t give much play at all, to accommodate trimming at the ceiling and floor, and walls / ceiling that went off plumb / level. This means that if the ceiling wasn’t level, it could start sloping either up or down, and that means the mural would start getting either cut off, or some white space might show at the top. By starting in the middle, I could split the difference between any irregularities, and, hopefully, over the 12′ width of the wall, now divided into two 6′ sections, any off-level sloping would be minimal enough that it wouldn’t visually impact the top or bottom of the design. I know that doesn’t make sense to a lot of you reading this, but I do have a number of paperhangers who follow my blog, and they do “get it” and hopefully will learn some new tricks.

Finished and ready for furniture – and a baby!
For this non-woven product, I used the recommended paste-the-wall installation method. I can see why the other guy had difficulty. This was a very thin, but stiff, material. I got wrinkles, too. It took some time and some finesse to urge them out of the paper. This is another reason why I started in the center of the wall. If wallpaper starts warping or wrinkling, it usually will cause the outer edge (the edge not butted up against the previous strip) to expand and twist. As each subsequent strip goes up, the twisting and distortion becomes magnified. You can’t butt a straight edge of a new strip up against a strip that is bowed out of shape on the wall. Thus, by starting in the middle, I can minimize the number of bowed edges. Instead of four, there will be only two. And the amount of distortion will be less per panel. I will note that this usually does not happen with non-woven materials.

A big chunk of mural was cut off by the door and lost to the trash pile. As the mural worked its way across the top of the door and down the right side, a different set of leaves, and a lot of blank area, was going to end up in that 6″ wide space between the door and the wall. I thought it would look cooler if the design of the foliage to the left of the door continued on to the right side of the door. So I saved the strip that got cut off by the door and then did some tweaking in various ways, and got that narrow strip placed to the right of the door. When you look at it, it appears that the leaves and fronds are passing from left to right uninterrupted through the doorway.

The home is in Bellaire, in Houston.

Foliage Update for Guest Bedroom

November 10, 2021
This small floral print was fashionable when it went up, 30+ years ago. But now it’s dated, and also some stains and dirt are showing. Time for an update!
Old paper has been stripped off, the walls have been primed with my favorite Roman Pro 977 Ultra Prime, and ready for wallpaper.
Done! An accent of grasscloth was used on one wall. I love the way the greens match, and everything coordinates with the paneling / wainscoting.
Usually I place the pattern so a prominent design motif sits at the ceiling line. But in a room with wainscoting or chair rail, that horizontal mid point in the wall is more visible. So I plotted to have the bottom of the dark green, most visible flower land just above the top of the chair rail. It looks like it’s growing from the wood! The pattern also just happened to land nicely at the ceiling line, with no major design elements getting cut in half.
The material has woven fabric look to it – but that’s just the printing. It’s actually a very flat paper. It was very thin, and reminded me of papers from decades ago. It hugs the wall very tightly. I liked it a lot.
Exclusive Wallcoverings
The grasscloth accent wall. All four strips were reverse-hung, and hung in the sequence they came off the bolt. Yet you see a color difference (called paneling or shading ) between some strips. This is quite typical of natural products like grasscloth and sisal.
Close up. Bad photo … the color is actually an attractive green. The material is more of a thin balsa wood about 1/2″ wide, rather than traditional grass or reeds. I feared it would be difficult to cut through, but it turned out to work very nicely. But it would not have been good in a room with corners or intricate details to trim around.

The home is in League City, a southern suburb of Houston.

Food Stains on Wallpaper

November 3, 2021
his wallpaper is on the backsplash of a kitchen counter. Over 30+ years, you can see splatters that have stained the paper.

t

On these pieces that I have stripped from the wall, you can see that the stains have leached through to the back of the paper. Since stains like this usually contain grease, they can bleed through to the new wallpaper, too. So it’s important to make sure that none have gotten onto the drywall behind the wallpaper. If so, a stain blocker will be needed to seal them off. Oil-based KILZ and shellac-based BIN are two good options.
On the right is the KILZ that I used to seal off these stains. It’s important to use the ” Original ” oil-based version, and not any latex or water-borne formulas…. they simply don’t perform as well, no matter what the label says. And know that the fumes are … well, they will get you high and knock out a few brain cells, so wear a respirator, or at least open the windows for good ventilation. Wallpaper paste will not adhere to oil-based products, nor will it stick well to the glossy surface of BIN. So, once the stain-blocker is dry, I go over it with my usual wallpaper primer, Roman Pro 977 Ultra Prime.

Paint Drip Preventer

October 8, 2021

I love this Ultra Prime Pro 977 wallpaper primer by Roman. But a year or so ago, they changed manufacturers of their labels, and the new ones have a plasticized coating, which doesn’t absorb dripped paint, but allows it to run down the side of the can – and potentially onto my dropcloths or onto the homeowner’s floors or countertops. Can’t have that!

My solution is to wrap bands of cloth around the cans, that will collect and absorb any drips.

Head to the thrift store … for less than a dollar each, I’ve tried collars and sleeves from T-shirts. But what fits best and absorbs the most – shhhh! Don’t tell anyone … these are the waistbands from baby underpants!

Crumbly / Unstable Wall Issues

June 2, 2021
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.

Starting Today – More Tomorrow

March 24, 2021

2-3 hours spent covering surfaces and baseboards, and then priming the walls in this large downstairs bathroom in a newish home in the Houston Heights. The primer is my favorite Roman Ultra Prime Pro 977, lightly tinted blue to make it easier to see where I have applied it.

I always think it’s cool to see the pattern as it goes up against the previously-bare walls.

More photos tomorrow!
