Open the Pool Bath Door and – SURPRISE!

May 28, 2022
Sink wall primed and ready for wallpaper.
Sink wall done. (except for a 1″ wide sliver on the left)
A larger view of this pattern. Don’t know why it’s showing pink here … it’s not.
The craze started years ago with the ” iconic ” Martinique tropical pattern, which has graced the walls of the Beverly Hills Hotel since 1942.
The design is fabulously lush, and overscaled.
Makes an unmistakable impact when you walk from the pool and into the adjoining bathroom and are met with – WHAM! Deep in the tropics!
My client was drawn to Brazilliance by Dorothy Draper. And of course, there’s the original Martinique. Both these versions are screen prints made with bad (IMO) inks on uncooperative substrates, and result in puckering within the wallpaper and curling at the seams. Do a Search here to read my experience hanging the Martinique.
In addition, these high-end papers are notoriously expensive. And a very long 41″ pattern repeat means there’s potentially a lot of waste – meaning, a lot of paper that is cut off and thrown away in order to match the pattern.
My client was open to suggestions, and happily found a much better option. This Daintree Palm by Graham & Brown is equally huge and stunning, but at a fraction of the price.
In addition, it’s printed on a non-woven substrate, which is much easier to work with, the vinyl surface is much more resistant to splashes and dirt, and it will strip off the wall easily when it’s time to redecorate.
I want to make the point that while this pool bath is not part of the main house, it does have air conditioning and heat – climate control are imperative to ensuring that wallpaper stays on the walls, and stays free of mildew and other issues.
The home is in the Garden Oaks neighborhood of Houston.

Starting to Smooth a Textured Wall

March 2, 2022
This is a typical wall texture provided by many builders of new tract homes in the suburbs of Houston.
Wallpaper doesn’t look good hung over this texture, because the bumps will show through. And the high-and-low ridges and dips interfere with good adhesion to the wall. So this accent wall will need to be skim-floated to smooth it before the wallpaper can go up.
In addition, this wall started out with a semi-gloss paint. I worry about my materials being able to stick to a glossy surface.
So, before applying the smoothing compound, I am priming the wall with something that will stick to the gloss paint, as well as provide a matt finish for the smoothing compound to adhere to.
I’ve discovered that my favorite wallpaper primer also works great for this purpose. It sticks to just about anything, and dries almost dead-flat. I like Roman Pro 977 Ultra Prime.
I use a trowel (top) to spread on the smoothing compound. The 3″ stiff putty knife is used to knock off big-ish chunks on the wall, or bits of grit. I use the 1 1/2″ flexible putty knife to apply the smoothing compound in tight spots like around electrical outlets or between a door molding and a wall corner.
The smoothing compound I use is drywall joint compound, and I like the Sheetrock brand Plus 3 version. Search hear (upper right) to see previous posts with photos of this material.
Bottom of photo – trowel sticking to the wall shows you just how tacky this stuff is. Above that are blobs of the smoothing compound waiting to be spread around, and a little bit on the left initially smoothed onto the wall. At the top of the wall you see a section that I have already covered with the smoothing compound. This will dry overnight, and I will sand it smooth tomorrow.
Sometimes I can float a wall, get it to dry, sand it smooth, prime, and hang the paper all in one day. But this texture is so heavy that more time is required for it to dry, so it will need an overnight sit. Some fans, plus the home’s heat and/or air conditioning help to pull moisture out of the smoothing compound and hasten dry time.

Solid Vinyl Paper Pooching at Seams

May 15, 2020


Today I stripped off this paper. It was dark and dated. But also, it had started curling up a bit at the seams.

The homeowners said this started after Hurricane Harvey, when they were without power for two weeks, and the lack of air conditioning allowed humidity to permeate the house.

So here we have paper-backed, pre-pasted, solid-vinyl wallpaper doing what it does best – succumbing to humidity, by allowing moisture to wick in behind the seams, which causes the paper backing to swell, pushing the vinyl surface back in a curl. Sometimes, the paper backing actually delaminates (comes apart from) the vinyl layer.

My main reason why I encourage people to steer away from these materials. The price point is attractive, but the quality and longevity is not.

Interestingly as a side note, it looks like the previous installer did not pay attention to the pattern match. Well, no biggie. On this design, it is not very noticeable, and the homeowners have lived with it happily for 20 years or more.

Please Don’t Tell Me You’re Ready If You’re NOT

September 27, 2019


This young family in the Rice University neighborhood of Houston has been undergoing a weeks-long remodel of the master bed and bathroom suite in their 1939 home. They’re eager to get moved back in. I was scheduled for three days to smooth walls and hang paper.

I’d been told by both the homeowner and the contractor that the room is ready for wallpaper. So I showed up for work today to discover that it is not.

First photo – The painters are working in adjacent rooms and need to pass through my work area frequently. You can see piles of their equipment in my space. This is very disruptive to the thought process needed to hang wallpaper.

Second photo – There is no running water. I had to run down to the family’s kitchen to fill a gallon bucket so I could rinse tools and rags – which is not the same as keeping things squeaky clean with fresh, running water. And since there is no toilet, there is nowhere to dump the dirty water.

On the left, you notice an extension cord. Which leads to the third photo – there is no electricity. No lights. So I had to connect two extension cords and hang one measly 100 watt bulb from the ceiling fan, in hopes of having enough light to work.

The fourth photo shows where I am trying to spread smoothing compound onto the wall. The compound and the wall are virtually the same color, and, in the dim light, it’s next to impossible to see what I’m doing.

The contractor dug out a heavy-duty extension cord and borrowed the painter’s work light, which helped a bit. But later the painter (who was working in a room with no windows) came and took his light back.

There is also skimpy air conditioning in this room. It’s not about the temperature, folks – it’s about humidity. You need the A/C cranking to pull humidity out of the air. I won’t hang wallpaper when the HVAC systems are not running, because the resulting humidity is detrimental to wallpaper – adhesion, shrinking, yada. And smoothing compound won’t dry, primers won’t dry …

Fifth photo – the carpet has been ripped up, leaving nail strips along the walls, and leaving exposed nails here and there all over the floor.

I did what little prep I could and then left. I am not coming back tomorrow.

Unfortunately, because of mis/discommunication, this family’s wallpaper will have to wait until I have a client whom I can switch install dates with.

Also, due to this, I lost at least one day of work (self-employed people don’t get “vacation pay” 😦 ), and other clients of mine whom I could have helped that day didn’t get their paper up, either.

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.
