An angled trim brush like this helps apply my wallpaper primer in tight areas the roller won’t reach , such as along crown molding and baseboards , and in corners. This is called cutting in . These brushes with the stubby handles are kinda new, and I’m liking them a lot.
This is the current wallpaper, and I’m to put a new paper in this powder room. For various reasons, this paper cannot be stripped off the wall , so I’m prepping the walls to be able to hang the new paper on top of it . Normally, my favorite Roman Pro 977 Ultra Prime will seal this effectively enough. But – hard to see in this photo – but this existing paper looks dirty to me. Some of that is due to the mottled look of the pattern / colorway . But I’m seeing tan discoloration , and I think it’s coming from under the wallpaper . This home was built in the early ‘90’s , and in a neighborhood where , through stripping off many old wallpapers in order to prep for new installation , I’ve noticed that someone working in that area and era used what we call clay-based paste . This paste is made using actual clay – i.e. dirt – and has a reddish color . I believe that this red clay paste is able to work its way through wallpaper, and creep onto the surface, causing a subtle “dirty” cast to appear on the wallpaper. Once you strip the old wallpaper off the wall, the wall can then be washed , and hopefully you’ll get all the clay paste off . But usually, no matter how much you scrub, residue will remain. I fear that that residue will work its way through the new wallpaper, as well. Additionally, the most severe stains are in the vicinity of the toilet – housekeeper splashing cleaning agents? or little boys with bad aim ?? Yes, most homeowners will never notice this, especially since it can take years to show up. And the paper I’ll be hanging is black , so it’s highly unlikely that any discernable stains will become visible . But I get a little anal about wanting jobs to look perfect. So I like to use a stain blocker , which will ensure that no discoloring elements will work their way through . My two favorites are KILZ Original , oil-based primer . KILZ is wonderful, unparalleled stuff. But it does have strong fumes , so you have to ventilate the room thoroughly and also wear a chemical respirator while applying it, to avoid becoming “high.” i.e. “sick” My other option is BIN , which is shellac – based . This is also an excellent stain blocker , and has a strong smell , but nothing that will kill your brain cells . Since my current clients have little kids, I opted for the BIN . Unless you want to go through a LOT of paint thinner and mess , you can’t easily wash oil-based or shellac-based liquids out of your roller cover or brush es . So I plan to use disposable rollers and brushes. This doesn’t mean cheap rollers and brushes – it just means that I factor in that these will be used once and then thrown away. Speaking of factoring in costs – the gallon of BIN was $70 (and that was a reduced price due to dented can). The KILZ was $40 , but I would have had to purchase a new respirator and cartridges , which would have added an additional $40 – some of the respirators went up to $70. March 2023 prices . All this needs to be considered when figuring up the price for doing a wallpaper job. I’ll also note that these products can be difficult to source – my local hardware store, which typically has stock even when larger outfits are out , had only one can of KILZ and one scratch-and-dent can of BIN . Whichever I would have chosen, I sure got lucky. Note that these stain blockers are formulated to block lots of nasty stuff – water stains , blood , rust , wood sap / knot holes , ink , tar , grease , crayon , lipstick , cooking stains , marker , Sharpies , etc. Back to BIN…. It’s very watery and runny and drippy . So you really have to cover the floors and baseboards , as well as countertops , toilets, etc. Microfiber roller covers help a lot to minimize splatters . Roll slowly and in an upward motion . Oh – additional plus … both BIN and KILZ dry quickly, so you can apply it and then move to your next step in less than an hour. Besides the shadow-y paste residue , this room has other issues . Here, someone used ink pen to mark placement of the hooks for the powder room mirror . Eeek! Ink will bleed through paint and wallpaper even faster than clay paste residue will. Here you can see one coat of the BIN applied – but the ink seems to have been “resurrected” and is actually enlarging and spreading, and bleeding through the stain blocker . Here I’ve spot-primed with a heavier coat of BIN , and that appears to be holding the nasty ink at bay . Note that wallpaper paste will not adhere to oil-based products like KILZ , and probably not to shellac , either, because it dries kind of glossy. So whichever of these primers you choose to use, you will need to top-coat with a primer formulated for use under wallpaper – and that will adhere to the stain blocker. Tomorrow, I’m going to follow up with Roman Pro 977 , as mentioned above .
This window had leak issues ( rain , sprinklers ) some years back, which have been solved by replacing the window, and doing other repairs. In the photo, I’ve applied my light blue wallpaper primer to the top half of the wall but not yet the bottom portion, so that’s why the color differenceEven though the leak has been stopped, vestiges of it are still appearing. Water that entered the wall left vertical streaks on the drywall . All these years later, after the paint and texture have been removed , the stains remain.Water stains , along with some others, such as blood , rust , ink , marker , grease , oil, cosmetics , and the like, will bleed through joint compound , primer , paint , and wallpaper , creating new stains on the surface . It may take a couple of months , but they will make an appearance . In this photo, I’ve already applied my blue primer. It only took a half an hour for these stains to work their way through. This is the top right corner of the window , where the bracket for the mini-blinds is attached to the wall. Note the stains on the underside of the window . To prevent these stains from working their way through the new coating / paint / wallpaper , it’s imperative to thoroughly cover them with a stain blocker . And – trust me – water-based products won’t work, despite what the label claims. You need an oil-based product like this KILZ Original , or a shellac-based like BIN by Zinsser . Both are prone to splatter , so be sure to cover your floor and baseboards with dropcloths . KILZ has strong fumes and can make you high , so ventilate or wear a respirator mask . It’s a hassle cleaning the liquid out of the brush , so I use a cheap-ish disposable “ chip brush ” from Home Depot or Sherwin-Williams . The products usually dry pretty quickly. Note that wallpaper paste won’t stick to most oil-based primers , and shellac is too glossy for good adhesion , so I’m going to go over the stain blocker with my usual Roman Pro 977 Ultra Prime wallpaper primer , which sticks to just about everything , and creates a good, matt finish surface for the wallpaper to cling to.
Here I’m preparing to hang wallpaper on new drywall in a new addition to a 1930’s home in east Houston . First I’ve used a damp sponge to remove all construction and sanding dust. Next I’m going to apply my primer. It’s important to note that, even though this is wall is a new sheet of drywall, it’s not all the same surface. We have mostly large expanses of drywall / greenrock (the type of drywall that’s used in wet areas ). But at the joints , and covering where the screws and nails hold the drywall to the studs , we have joint compound . That’s the strips of white areas. And next to the crown and door molding and the baseboards is overspray from the paint that was applied to the wood trim. Here I’ve applied my light blue-tinted wallpaper primer over the top 1/3 of the wall. It’s important to be sure that the primer you use is suited for use under wallpaper . But also that it will properly adhere to and seal all the surfaces on the wall . My primer (below) will stick to just about anything. But this photo is interesting. Because my primer has been rolled on evenly across the wall , and cut in with a trim brush along the trim and corners . But you see that the primer is drying at different rates . On the right side of the photo, the primer is applied over the bare drywall, and it’s drying quickly. But toward the left, next to the door trim , the primer is drying more slowly. This is because there is paint overspray next to the door trim . The paint is semi-gloss enamel , and my wallpaper primer reacts with it differently from how it reacts to flat paint or drywall or other surfaces. Not a big deal. Just be aware of the need for different dry times due to different surfaces the primer is applied to. My preferred wallpaper primer is by Roman , called Pro 977 Ultra Prime. It’s not readily available, but you can find it on-line. All Sherwin-Williams stores can get it from the distribution center – but not all store managers know that, or are willing to do so. I get mine from Murphy Brothers Paint on Bissonnet near the Rice Village , who stocks it just for me.
Two weeks before a job is to start, I send my clients a “check list” so they know how to prepare for Install Day. It includes things like check to be sure it’s the right wallpaper pattern, how I can get into the house if the homeowner is away, how much space I need for my set-up, etc.
It also says quite clearly that all construction work has to be completed, and there needs to be electricity, light, nearby running water, and no workmen coming in while I’m working, and no workmen coming in later who might mess up the paper.
This ensures that I will have optimum working conditions (I need lights so I can see what I’m doing. I need water so I can keep your paper clean.) And you don’t want Bubba coming to hook up a light fixture and put his sweaty hands all over the new wallpaper in the process. Or a painter coming to touch up, who decides to “protect” the new wallpaper by putting blue tape on it. Of course, when he removes the tape, the surface ink or the wallpaper itself will come along with it.
Yet you would not believe how many people – innocently or desperately – tell me they are “ready” when they really are not. Here is an example of a house that is not ready for wallpaper. It is very likely that the paper will be damaged by tradesmen who come to “finish up.”
Baseboard is not in place. When positioning the baseboard, it’s likely the carpenter will bang into the wallpaper. When painting, you can bet the painter will get paint onto the new wallpaper. Or, as mentioned above, he will use tape that, when he goes to remove it, will pull the inked surface and / or the paper itself off the wall.
Door molding is not in place. Same issues as above.
No electrical outlet in the room. What if I need to use a fan or heat gun? And wallpaper will sit tighter to the wall if I can put the plate cover in place immediately.
The electrician is not finished. This switch sticking out of the wall is just plain dangerous. In addition, when he time comes to finish whatever it is he’s working on, he will probably put his greasy hands on the wallpaper, or lean his scratchy tool belt against the paper.
My checklist says I need clean, running water in the immediate area. It specifically says NOT a hose in the yard. Yet look where I had to get my water. (I was working on the THIRD floor.) This house had no faucets, no drains, and not even a working toilet.
Dining room in the Oak Forest area of Houston, before. All white and crisp – but bland .Here with just a touch of color and texture . The homeowner took my suggestion to use an embossed vinyl faux grasscloth product, which is very consistent in color . The problem with real grasscloth is that so very often there are disappointing color variations between strips , even if they come off the same roll . We call this shading and paneling . Do a search here to see previous posts about this. Note that with both materials you will see the seams. With this faux material, once you got 3′ away, you can’t see the seams at all. The paper along the top of the wainscoting chair rail is to prevent my wallpaper primer from splattering onto the molding . I do the same for baseboards and bathroom backsplash es .Opposite corner done. Close-up showing the realistic texture of the vinyl product .This is by Designer Wallpapers and was purchased from the Sherwin-Williams in the Rice Village , by Dorota , who has been selling wallpaper for 25+ years and is THE expert on helping you select your perfect pattern .
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.
A dropcloth on the floor, and covering the shoe mold and baseboards, would have prevented these splatters on the homeowner’s hardwood floor. Much worse as a close-up. Such a shame.They didn’t bother to remove light fixtures, towel bars, or even switch plate covers. Here you can see how paint got slopped onto the beautiful metal sconces.Paint falls on door handles and towel bars, too.While priming, I throw a damp washcloth over door handles and towel bars, to prevent speckles. I use other material to cover light fixtures.
Before. Getting ready to prime. Note that I have protected both the floor and the baseboards with dropcloths. Done! Dramatic!Detail.This bolt had been damaged in shipping, and the right edge had dings / dents. With this thick, puffy non-woven material, these could show at the seams when butted against the next strip. So I plotted the placement of my strips so this one would be on the far right end. That last strip was not the full width wide, so 8″ of the right side got cut off where it met the adjoining wall. That eliminated the worry of those dented edges showing.I used the paste-the-wall method to hang this non-woven wallpaper. With the wall wet with paste, it would be easy to get paste all over the wallpaper if you used the traditional installation booking technique. So I’ve learned to roll the material up with the print side in, and then secure with a hairband (from the dollar store). Then you can easily carry the rolled-up strip up your ladder, remove the elastic tie, and then let the paper fall into place. Only the back side comes into contact with the paste on the wall. Once you get good at this technique, you will never have to wipe paste off a seam, nor off the woodwork or adjoining walls. Cole & Son says that this “Woods” pattern has roots dating back to 1959. I guess that makes it truly iconic. I can say that it is quite popular – I’ve hung it a bunch of times.
In the photo, look above and to the left (10 o’clock) of the electrical outlet. You will see splatters of paint from when the walls were painted, and the workers didn’t bother to cover the baseboards – in this $$$ new home in the Greenwillow / Willow Meadows neighborhood of Houston.
There are a lot more speckles that don’t show up in this photo.
I can’t stand these little splatters,,, and they are easy enough to prevent. So before I roll primer onto a wall, I pin protective strips of dropcloth material along the tops of the baseboards, to catch any splatters or drips.
It takes more time, but it protects the homeowner’s baseboards, shoe mold, and floors from speckles and tiny splatters.
