Don’t Skip the Wallpaper Primer!

October 30, 2019


A primer is imperative for a good wallpaper installation – and I mean a primer designed to be used under wallpaper, not a generic primer or a paint primer.

A good primer will

seal porous surfaces
mitigate a glossy surface (paper won’t stick to gloss)
allow for “slip” and repositioning while installing the paper
provide “tooth” for the adhesive to grab ahold of
withstand the torque created when wallpaper dries and pulls taught,
preventing “popped seams”
protect the surface, making future removal of the paper easier while
preventing damage to the wall

Ultra Prime Pro 977 by Roman’s is my preferred primer.

But different situations call for different primers. When hanging on a thirsty surface like new drywall or a textured wall that has been skim-floated, I will use Gardz by Zinsser. Other primers could be called for in other situations.

Sweetening an All-White Bathroom / Treating Trials

July 2, 2019



This homeowner was just trying to update her hall bathroom. She chose a new countertop, new tile, and new wallpaper. Unfortunately, some of the workmen who showed up for the job were less than stellar. I won’t say anything about the tile guys or the painters, but in the top photo, you can see how the “I can hang wallpaper” guy prepped the wall… which he proclaimed as “wallpaper-ready.”

I took down the light fixture, removed the remaining old wallpaper, and skim-floated the surface. Because the ridges in the original guy’s float job were so thick, I went there a few days early to get an initial layer of smoothing compound spread on the wall, so it would have time to dry. Then when I came back, I skim-floated the entire room. Because this second coat was thinner, it dried in a few hours (with fans, a space heater (to pull humidity from the air), and the home’s A/C unit cranking dry air through the room.)

I sanded smooth, vacuumed and wiped off the dust, and applied a coat of Gardz, which is my preferred primer for newly smoothed walls.

Mysterious tan dots worked their way through the smoothing compound and the Gardz. I didn’t know what they came from (mold, oil, tobacco, soft drink or food the workers splashed on the walls?), but I knew they would eventually bleed through the new wallpaper. So I rolled on BIN, a shellac-based stain-blocker made by Rust Oleum, to seal the wall.

This effectively sealed the stain, and the wall was nice and white after that.

A week later, I came back to hang the wallpaper. First I applied a coat of Roman’s Pro 977 Ultra Prime, a primer made specifically for wallpaper. For some reason, this product didn’t stick well to the BIN – which is surprising, because one reason I use this primer is because it sticks to anything, even glossy surfaces (the BIN was not particularly glossy). Look closely or enlarge the third photo, and you will see it sliding and dripping down the wall. Well, no fear. I brushed out the worst of the drips, and as the primer dried, it tightened up and clung flat and tight to the wall.

With the wall finally smooth and appropriately primed, I was ready to get that paper up on the wall. This was an old fashioned pulp paper, which the British companies were making before most of them switched to non-woven materials. I was looking forward to working with an authentic pulp paper, because it’s been a while since I’ve come across one.

But this one didn’t behave as most of them do… It was thicker and stiffer, which made trimming and intricate detail work difficult, and increased the potential for creasing (for instance, while fitting the paper into a corner at a ceiling line). And it sucked up paste and dried out way sooner than I could get a strip to the wall. So I ended up using a spray bottle to add extra moisture to the back of the paper while I was applying the paste. This did help a lot.

Some of the edges had been banged up during shipping, so some of the seams looked a little weathered. And the edges had not been cut perfectly straight at the factory, so we had a bit of what we call “gaps and overlaps.”

Still, the finished room looks great. With its sweet flowers and calming colors, the pattern reminds me of the Laura Ashley era. The blue really pops against the white woodwork and tile in the room, and the red roses are nothing short of romantic.

Such a happy turn-around, for a bathroom that started out full of trials and tribulations.

I’m not sure what the brand name is, but the label says “English Florals.” The homeowner found it on-line (free shipping!), and the cost was low – about $60 for a double roll bolt. The home is on the north side of Houston.

Blue Faux Grass on Bookshelves

May 12, 2019


Awwwk… my “before” photo didn’t turn out. Oh well … just know that originally the shelves and the back of the shelves were a bland white paint.

To prep, I primed the glossy white paint with Roman’s Ultra Prime Pro 977, which will stick to the enamel and which is formulated to provide a good surface for the wallpaper to adhere to.

The wallpaper is an embossed vinyl faux grasscloth by Thibaut, from their new Texture Resource book. This man-made product avoids the color variations and very visible seams that are common with real grasscloth, so it’s a good option.

The material comes 27″ wide, and the bookshelves were 28″ wide. So I had to use two 14″ wide strips of paper for each cubicle and put a seam down the middle.

Isn’t the blue color gorgeous as a backdrop for the contents of the shelves?!

This was a work desk area off the large kitchen in a home in West U (Houston).

The interior designer this job are Danna Smith and Pamela O’Brien, of Pamela Hope Designs.

Wall Prep – Missing Chair Rail and Stain Repair

March 31, 2019


What an unexpected surprise I got when I arrived at work to discover that the chair rail in this entry had been removed (top photo). Not only did I need to figure how to get enough paper to cover the additional wallspace, but I needed to smooth over the damaged wall area where the molding had been torn off. (See previous post)
I skim-floated the wall and sanded smooth. It looked great. But brown coloring from the torn Sheetrock had worked its way through the smoothing compound (second photo). Torn drywall is not something that I would normally worry about bleeding through wallpaper (you are concerned mostly with things like grease, ink, water, tobacco, rust, and the like), but this stuff was 60 years old, so who knows what its properties and characteristics were back then? And besides, it had already worked its way through a layer of joint compound – in just one night! No sense in taking the chance that it might bleed through this nearly-white grasscloth natural fiber wallpaper.

The Gardz penetrating primer / sealer (not pictured) I planned to use on the wall would be fine to hang wallpaper on, but could not guarantee that that brown stain would not work its way through the primer and through the wallpaper.

I applied the Gardz, because it’s a great penetrating substance that seals new smoothing compound, and also provides a good surface for hanging wallpaper on. Once that was dry, I followed that with a coat of KILZ Original, an excellent oil-base stain-blocker. But wallpaper paste will not stick to the new KILZ formula (required in order to comply with current EPA requirements.

A little 3″ width around the lower center of the room with wallpaper not sticking tightly to it probably would not be problematic. But you never know, and I didn’t want a “hula hoop” of delaminated wallpaper circling the room. So once the KILZ was dry, I followed up with a coat of a wallpaper-specific primer, Romans Ultra Prime Pro 977.

Now the room is ready for wallpaper, without fear of a band of tan bleeding through the new surface.

’90’s Check to Magnolia Buffalo Check

February 2, 2019


The differences in the before and after photos are subtle, so look carefully!

This laundry room in a far-north neighborhood of Houston (Louetta & I-45 area) happily sported it’s black & white checkered pattern for many years. The wallpaper dated to the ’90’s, but still looked fresh, and the homeowner loved it.

But an unfortunate water leak caused damage to the window wall, and a poor repair job left a very visible pattern mis-match over the window. Then another water leak required new drywall to be patched in behind the washer and dryer (see top photo). So once the repairs were made, the homeowner wanted to redo the room, and do a little updating along the way.

I stripped the old wallpaper, performed necessary patching and prep, primed the walls with Roman’s Ultra Prime Pro 977 wallcovering primer, and came back the next day to hang the new paper.

The new pattern is also a black & white checkered design, but it’s larger-scaled, and is just large enough to be called a “buffalo check.”

It’s also a freer design – meaning that the wavy edges of the vertical and horizontal pattern, along with the watercolor features of the ink, afforded me some breathing room while dealing with walls and ceiling that were not perfectly plumb and level.

This pattern is in the Magnolia Home collection (Joanna Gaines) by York Wall. 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.

Lazy Painters / Lousy Painters

July 4, 2018

First photo – you are looking at a very close view of crown molding. Note that the bottom edge of the molding is painted dark green, the same color as the walls. This bottom edge is supposed to be the same color as the rest of the molding.

In the second photo, I have brushed my primer on the wall, and so you can see more clearly the dark paint on the bottom of the molding.

Some painters are too lazy (or unskilled) to cut a neat line along corners and the join points of walls and moldings. So they often let their paint brush just swipe the bottom edge of the crown molding. It’s easier and faster than taking the time to tape off the molding, and it takes much less skill than carefully manipulating the brush to paint the wall, and not the molding.

This is a shame, and I hate to see it. To me, pretty moldings are one of the most classy elements in a home. Putting the wall color on the under edge of the crown molding sure does a lot to ruin the effect of the nice molding.

The primer I am using (Roman’s Ultra Prime Pro 977) is white, and in the third photo you can see that I have tried to cover some of the dark green paint. My primer is not paint, though, so, while it helps, it does not cover well. The green paint is still visible, and looks something like a ghost hovering in between my silver and white wallpaper and the white crown molding.

Stripping Off Old Wallpaper

February 14, 2018


This hall bathroom in a 1955 ranch-style home in the Briargrove / Tanglewood neighborhood of Houston was damaged by a roof leak during Hurricane Harvey. The contractor’s guys did a good job replacing drywall and painting the woodwork, but they fell short when it came to wallpaper. See first photo.

But this just gave the homeowner a chance to choose something that coordinated better with the decades-old tile that she loves (and that I love, too), and to pick a paper with more color and flair, that is more suited to her taste. See tomorrow’s post for that.

My first task was to remove the existing wallpaper. It turned out that there were two layers of paper, and, in some places, THREE layers.

In the second photo, I have removed most of the top (new) paper, which is the aqua trellis by Thibaut. I took it off by simply tearing it off the wall. Below it, you see the green savoy (small, tight, squiggly) by Waverly. Interestingly enough, I have hung this a bunch of times – in the ’90’s. 🙂

This paper was attached more tightly to the wall. To remove it, I had to first separate the top inked layer from it’s paper backing. You can see this in the second photo. Once the top layer, with it’s water-resistant acrylic surface was removed, it left behind a white paper backing. I used a sponge and bucket of hot water to soak the backing. It didn’t take long before the underlying paste reactivated, and then it was ready to let go of the wallpaper. You can see clean wall revealed in the photo, where the layers of wallpaper have come away.

In one area of the room, I got a surprise. There was a third layer of paper under the others. The top vinyl layer had been stripped of eons ago, but the tan, gritty paper backing was left on the wall. You can see this in the third photo dry (light tan) and soaked with water (dark tan). Once that tan paper backing got soaked enough with several spongings with hot water, the paste reactivated and the paper was happy to come away from the wall.

I was uncommonly lucky today, because whoever hung the original wallpaper had taken the time to prep the walls correctly. First, he skim-coated the textured walls to yield a smooth surface for the paper to adhere to. Second, he applied good quality penetrating sealer. This sealer might have been Gardz, a product that I use now, or another similar sealer, perhaps even a solvent-based (as opposed to water-based) sealer. His sealer provided a hard surface for the new paper to stick to, and also gave a surface that was resistant to all the water I was using to strip off the old wallpaper.

Check out the fourth picture to see the huge pile of wallpaper I pulled off this one small hall bathroom.

Once all the paper was off, the walls were in very good condition. There were no delaminated areas, no lifted areas, nothing that needed patching – just an amazingly intact surface.

I did a few little touch-ups to a few little areas (I wanted to clean up 60 years of grime collected along the top of the tile), and then rolled on my favorite wallpaper primer, by Roman’s, their Pro 977 / Ultra Prime. It’s a white pigmented primer, and is a wonderful surface to hang wallpaper on.

Peeling Paper Caused by No Primer Underneath

September 22, 2017

These wallpaper jobs are failing, mostly due to the fact that the previous installer did not prime the walls before hanging the paper.  With no primer, the walls are porous and will suck paste off the paper, leaving little to hold the paper on the wall.   Bathroom humidity has exacerbated the problem.

The top photo shows a paper-backed solid-vinyl paper, which are usually pre-pasted and lower-priced.  These are particularly bad for humid areas, because the paper backing tends to absorb humidity, expand, and push away from the wall.

The striped paper is a paper, which usually perform well and hold tightly to the wall even under humid conditions.  But with no primer to seal off the thirsty wall underneath, the paper has nothing to grab ahold of and is curling away from the wall.

In fact, when I went to strip the paper, it came off in whole sheets with just a gentle tug.  I had the entire bathroom stripped in, literally, about two minutes.

Before hanging the new paper, I will be sure to prime the walls.  The last photo (bottom row) shows two of the primers I will use.  The Pro 977 works on walls that are clean and have been previously sealed.  The Gardz is a penetrating sealer that is good for porous walls like flat paint, new drywall, or newly skim-floated walls.  It will also work on walls that have a bit of residual wallpaper paste because it seals it and makes it inert.

 

Spring Time in a Powder Room

I forgot my camera yesterday, the day I stripped off the old paper and prepped the walls, so I cannot show you the 15 year-old wallpaper with its curling seams, due to 1.) being an inexpensive paper-backed solid vinyl wallpaper (my least favorite kind – do a Search here), and 2.) the previous installer did not prime the walls but instead hung the wallpaper directly on the new home’s bare Sheetrock, and 3.) age, heat, and humidity. The pattern, however, was not too dissimilar to this one, being a sort of “impressionistic painting” design in the same blue, pink, yellow, and green color scheme.

Anyway, the new powder room looks fantastic. The colors are similar to what the homeowner had before, but this wallpaper should hold up much better. The material is paper (not vinyl), and will hug the wall tightly. I removed every scrap of old paper and sealed the walls with a penetrating sealer named Gardz, and then primed with a wallpaper-specific primer called Roman’s Ultra Prime Pro 977.

On top of this good foundation, the new wallpaper is a pre-pasted, raised-ink paper by Thibaut, and is one of my favorite products to work with, and I also love it’s dependable performance down the road. The pattern is #6936, and is very similar to their “Augustine” hummingbird design (Do a Search here). I love the barely-discernible texture of these raised-ink papers. A unique printing process results in this effect.

This wallpaper pattern is by Thibaut Designs, and was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby. (713) 520-6262 or dorotasouthwestern@hotmail.com.

Wallpaper Primers

April 20, 2017

Digital Image


There are lots of “wallpaper hangers” out there who slap paper up on the wall without a thought to prep. To do the job right, and to help ensure that the paper will stay on the wall for years to come, one of the basic steps is to apply a good primer.

There are different primers that will work under wallpaper. Here are a few that I use, depending on what the situation is in the room.

Roman’s Ultra Prime Pro 977 is a white-pigmented wallpaper-specific product, and it is my primer of choice.

But when I have skim-floated walls to smooth them, the new surface needs to be sealed, and Gardz is a wonderful product for that. It also seals and binds torn drywall. And it is also a good primer for wallpaper.

KILZ Original (oil-based) is called in when there are stains (water, rust, smoke, grease, etc.) or other problems that might bleed through the new wallpaper. For decades, KILZ was my go-to primer for wallpaper, too. But in recent years, to keep up with regulations from the EPA, the formula has changed. This primer may be more compatible with the environment, but the chemical make-up has changed, and wallpaper paste no longer wants to stick to it. So it’s used to seal stains, and then another wallpaper primer is applied on top of it.
