Smoothing Over A Mess

August 3, 2022
This kind homeowner had the sink / vanity in this powder room removed. This makes it a LOT easier and faster for me to to get the wallpaper up, and with less stress on the paper and fewer relief cuts .
Removing a sink that’s attached to the wall often damages the surface. Here you can see how the workman used spackle compound to cover the torn drywall and other damage.

Close-up. This isn’t a very smooth surface, and the wallpaper will have a hard time grabbing ahold and adhering. It’s also way too porous and crumbly to support wallpaper.
In the top photo, you see where I have applied smoothing compound on the upper portion of the wall. I’m working my way down.
Once it’s dry, I will sand and prime it, and it will be nice and smooth.
Here’s a shot of the fresh smoothing compound, before sanding.
Some people use a drywall taping knife or a broad knife to apply the plaster-like substance. I prefer the trowel you see in the photo, because it gives me more control and precision.
The 2″ flexible putty knife is for getting into smaller areas. The 3″ stiff ” Hyde ” putty knife is for knocking off high points or bumps on the wall before applying the smoothing compound.
This process is called skim-floating or skim-coating .
I like to use the Plus 3 lightweight joint compound made by Sheetrock . We just refer to it as mud . Find it in the drywall aisle.
The Plus 3 spreads on easily enough, sands easily , and the dust falls to the floor where it can be vacuumed up easily – as opposed to getting air-borne and drifting all over the place.
This box, which is approximately one cubic foot , weights 32 pounds . Ugh. Try carrying that across a parking lot and then up to the third floor of a townhome!
I like to transfer the material to a 5-gallon bucket. This is what it looks like in the bottom of the bucket.
Easy to scoop out. When I’m finished, I use a wet hand to smooth down the surface, wipe residue off the sides of the bucket, then place a thick sheet of plastic over the surface to keep air from drying it out. Then, of course, I put the lid onto the bucket.

Wall Prep Ahead of Wall Re-Do

July 20, 2022
This wallpaper in a Houston Heights townhome’s breakfast area was hung by “the contractor’s guy ” and he ran into some problems. First, I suspect the wall had not been adequately coated with a primer designed for use under wallpaper . This may be a large part of why the paper has come loose from the wall in places, and shrunk and gaps at the seams.
The wallpaper is an old-fashioned British pulp material , which is quite different from the non-woven material that this company usually prints on. If the installer was not familiar with hanging a pulp, yes, he can have a tough time of it.
There are other issues that the homeowner is unhappy with, such as tears, slices, patches, and, of course, these un-stuck seams. I’ve posted more pics previously, if you can Search to find them.
My task is to get the paper off and then prep the wall for hanging new material.
Most of the paper pulled off the wall easily. But there were areas where the guy had used a stronger adhesive to try to hold the edges down. Those would not come off the wall without causing damage to the wall. So I pulled off the top, inked layer and left the paper backing on the wall.
This stuff is porous and will bubble when coated with a water-borne primer , and with wallpaper wet with paste.
So I sealed these areas – I sealed the entire wall, in fact – with Gardz (by Zinsser ). This stuff is pretty incredible. It’s a thin, watery primer / sealer that soaks into the surface and binds loose components together, then dries hard and solid .
Latex paints and other water-based products (usually) won’t penetrate it, so won’t cause the underlying material to re-wet, expand , and bubble .
Just a note … due to pandemic and other supply chain related shortages , Gardz has become difficult to find. This can was about 1/4 full and I had it sitting behind my trash can, intending for weeks to toss it out. Now I’m glad that I procrastinated!
Once the Gardz sealer was dry, I skim-floated over it with joint compound , a.k.a. ” mud .” In most areas of the wall, my skim coat was as thin as possible, but I did have to make it much thicker over the areas with the paper backing stuck to the wall.
I set up three fans , and also used my heat gun , to get the smoothing compound to dry. I like the Plus 3 version made by the Sheetrock company. It sands easily and doesn’t make too much air-borne dust.
It took a couple of hours to dry. Then I sanded it smooth , vacuumed up the dust with my Shop Vac , used a damp sponge to get residual dust off the wall , and then let the wall dry once again.
Finally I applied a coat of my favorite wallpaper primer, Pro 977 Ultra Prime by Roman. I used a paint roller to roll it on to the main areas, and an angled trim brush to cut in around the ceiling and moldings.
Here is the wall all smoothed and primed .
Originally I had planned to strip , prep , and hang this half-wall all in one day. But ended up the prep took more time than I anticipated (about 8 hours ) , so we’ll let the primer dry overnight and save the wallpaper installation for another day.
The wallpaper pattern is called Strawberry Thief and is by the famous William Morris designer from the very early 1900’s . I’m sure seeing a surge in interest in his patterns, particularly this one. Do a Search to see other jobs I’ve done with it.

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!

Mess Stripping Wallpaper

February 6, 2021

Over the years, this powder room ended up with at least four layers of wallpaper. Some had been stripped down to the backing layer before the next layer went up, sometimes a primer was used, and in other cases, the installer simply plopped the new paper on top of the old.

The homeowners attempted to remove the multiple layers of paper. This mess would have been difficult to begin with, but, to complicate things, unfortunately, they pulled some bad information off the Internet. You can see how the use of a “paper tiger” scoring tool caused damage to the wallpaper as well as to the surface underneath – and didn’t help at all to loosen the old wallpaper.

My solution was to peel off the top layer of vinyl paper – the brownish striped faux finished pattern in the upper left of the photo. Then I used a sponge and lots of water to soak the tan backing until the paste reactivated and the paper could be scraped off the wall.

I would have preferred to also take off the layers of paper that remained underneath. But time was a consideration, and also the likelihood of damage to the wall surface. And I wasn’t sure if there was drywall or plaster under there.

So I used the product Gardz to seal off the revealed wallpaper. (Do a Search here on the word ‘Gardz” to learn more about this ingenious product.) Once that was dry, I skim-floated over the entire surface, to create a new, plaster-like layer. That was allowed to dry overnight.

The next day, I sanded this skim-float layer smooth. Because the smoothing compound had to be applied thickly, this resulted in a massive amount of dust. Luckily, it was all contained in the powder room, and was easily vacuumed up.

Then I used a damp sponge to wipe residual dust off the wall. This was followed by another coat of Gardz – a product that soaks in, dries hard, and effectively seals the surface. It’s a good sealer for new skim-coat, and it also works nicely as a primer under wallpaper.

With fans blowing on it, it dries quickly, and I was able to start hanging paper in an hour or so.
