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 couple in a nicely updated 1939 home in the Montrose neighborhood of Houston has a blank wall in the back of their large walk-in closet. They have a lot of colorful , modern art and wanted a backdrop for it that would be fun, but wouldn’t compete .One of the gals is an administrator for the athletic department in a local school district – so this small print “ Swimmers “ design is just perfect. In fact, the day I hung this, she was away at a swim meet in Austin ! Note that Spoonflower offers scores of designs under the “ Swimmers “ name, so be sure to check all of them, and all the colorways they come in, too. Detail Spoonflower is a little different from most wallpaper companies, in that it’s material comes in individual panels, or sheets – which they call rolls . Each of these is 24” wide, and then you choose the length you want, between 3’, 6’, 9’, and 12’. Each roll comes nicely packaged in an individual thick plastic zip-lock bag . These ones are upside down, so I had to re-roll them so the pattern would be coming off the top of the roll . Here are some tips about hanging Spoonflower. First of all, I like their “ Pre-Pasted Smooth Removable “ option. And it’s the only one I’ll work with. Their “ Traditional Pebble “ is a heavy vinyl that requires special trimming , bubbles, and is better suited for commercial spaces. And, the Peel & Stick – well, everyone ought to forget that sad stuff. Please read my link to the right about that material. In this photo, you can see that the white material is thin and translucent , allowing things underneath to show through, sort of like a shadow . So I need to be careful to make my pencil marks and notes on the wall very lightly. Side note: Never write on the wall or paper with ink or marker or crayon or grease pencil – it will bleed through the wallpaper . This is a pre-pasted material , meaning that a thin layer of paste is already applied to the back. To activate the paste , all you need to do is dip it in water , run it through a water tray , or spritz the back with a squirt bottle (uneven and kills your wrist) . Their paste is quite adequate. But I do like to have a little extra assurance, so I will roll on a little of my Roman 780 wallpaper paste onto the back. Then I take a sponge and drip clean water from a bucket onto the back of the paper . Next I use a paint roller to spread the mixture of water and paste around the back . This both activates the pre-paste, and also spreads around a little extra adhesive . Next, the paper gets folded pasted-side-to-pasted-side ( called booking ), then rolled or folded loosely. I like to dip the ends of the rolled strip into a bucket of water – just 1/8” or so, to prevent them from drying out while booking. Then the strip is placed in a plastic trash bag to prevent it from drying out during the booking period – a few minutes. I use this time to paste and book my next strip . Spoonflower Pre-Pasted Smooth is a little different from most papers, because it’s designed to be overlapped at the seams. Here I am lining up a seam. This overlap does show as a ½” wide ridge along the entire length of each strip. With busy patterns, it’s not very visible. Even with sparse designs like this one, once it’s dry and flat, you don’t notice. Here’s the overlapped seam looking toward the light, which is leaving a very minor shadow. And the overlap can be a good thing. For starters, most wallpapers shrink a little when the paste dries, so you can end up with slight gaps at the seams. Overlapping eliminates that. Also, if a wall is unstable underneath, due to incompatible layers of paint , or dusty walls, or other, the tension of these drying strips of paper can cause the layers inside the wall to come apart / delaminate – and that will result in paper that comes away from the wall, taking layers of paint and etc. along with them. This usually cannot be repaired or “ glued back down .” (Do a Search here to learn more) So overlapping the seams disperses the tension caused by the drying paper, and eliminates any seam from landing on the wall (because the sheets are overlapped ), so no popped seams .Here is the seam looking away from the light.Because Spoonflower Smooth Pre Pasted is thin paper and water-activated , it absorbs a lot of moisture from the water. So the material can’t help but expand . This can result in bubbles on the wall. Also, when air pockets develop, there is nowhere for the air to escape, so, again, bubbles and blisters. If there are huge bubbles, it may be worth taking a brush or plastic smoother and chasing them out. Or using a pin or razor blade to poke tiny holes to let the air out. But, really, if you can just relax and let nature take its course, as the paper dries, these bubbles will dry flat and disappear. Trust me. Another thing that can happen is wrinkles . These tend to form in the same place on every strip , and coordinate with how the paper was booked and rolled after pasting . The worst of these can be chased out with a plastic smoother. But there are dangers to over-using the smoother tools. Doing so can stretch the wallpaper and cause it to warp, which means the pattern might not match up perfectly on the next strip. Or it might cause wrinkles that can’t be brushed out. Again – if you can just sit tight and let the paper dry naturally, the creases and folds will disappear. I did some experimenting and found that booking and then rolling the strip up like a newspaper resulted in more wrinkles.It worked better to paste, book, and then fold gently and loosely. Then into the plastic bag to sit for a few minutes . Spoonflower PrePasted Removeable Smooth . I like this stuff. Removeable means that it’s designed to strip off the wall easily and with no/minimal damage to your wall when you redecorate down the road. I suspect this is made by York , as it’s very similar to their SureStrip line . Good stuff. The order comes with a mock-up of the strips / rolls you’ve purchased.Install instructionsPromo info from Spoonflower .
Today I was prepping a room in a home in Kingwood (far northeast Houston) that was damaged during the flooding from Hurricane Harvey in 2017. Look at what some contractor did – he went and wrote on the wall in INK!
Most EVERY workman of any type knows that you NEVER write on walls with ink – nor crayon, Sharpie, lipstick, or other.
Reason being, that these substances will work their way through wallpaper (and paint, joint compound, and other substances, too). It may happen quickly, or it may take a few years, but these materials will show themselves eventually, as ghost-like stains on the wall.
Other things will cause staining, too, like blood, water, rust, oil, grease, food, wood sap (knot holes), and more.
Luckily, there are dependable stain blockers on the market that can be brushed on. I like oil-based KILZ Original, but shellac-based BIN is good, too. Water-based products don’t perform as well, no matter what the label or salesman says.
I like to be extra sure, so, when I can, as in this case, I will take a knife and cut around the stain, then dig into the drywall and remove the top layer, taking the ink with it. This way it is GONE, not just covered up.
Of course, the remaining exposed / torn drywall needs to be sealed, skimmed over, sanded smooth, and then prepped for paint or wallpaper.
But all that is worth it, when you can be assured that no stains will bleed through the finish coat.
Well, this has been a month of issues with stains on walls! I was smoothing these textured walls with joint compound, and noticed some red splotches on the paint. I studied them, but decided they were paint, which is stable and not a problem. But a little after I had skimmed over the spots, I looked again and noticed that the red color had bled through.
Evidently it was ink, or lipstick, or child’s crayon, or some other such substance. Along with rust, blood, water, oil, mold and mildew, and a few others, these materials will bleed through paint and wallpaper. It might not happen right away, but eventually you will notice stains on the paper.
These stains can be sealed with a stain-blocker. I like oil-based KILZ Original, but the shellac-based BIN primer is good, too. Water-borne sealers may be environmentally-friendly, but I don’t trust them to work as well.
But in this case, I preferred to just get rid of the questionable areas. I took a knife and dug out the part of the wall that had the red spots. Those are the chips I am holding in my hand. Then I skim-floated over the area to smooth it, and proceeded with my wall prep and wallpaper installation.
The two holes in the wall are from picture hooks. See the little “X” under the holes? That’s from whoever was hanging the hooks. He was measuring and marking the wall, so he would know where to hammer in the nails for the hooks.
The only problem is that he used a ball point ink pen to make his marks. Ink is bad because, diminutive as this “X” is, it will bleed through wallpaper. It will bleed through paint and other materials, too.
Other substances that can bleed through wallpaper include water stains, oil, grease, wax (crayon), tar / tobacco, blood, rust, and more.
There are special stain-blocking sealers that can be used to cover these types of marks. KILZ Original is one that I like, and BIN is another.
Since this was tiny, and since I was skim-floating the wall to smooth it anyway, I just used a putty knife to dig the mark out of the wall. Gone! That way I don’t have to worry if a stain blocker will do its job sufficiently. Then I skimmed over the gouge with joint compound to smooth the surface.
The contactor added wall light sconces on either side of the sink, and he also hung the heavy mirror. For some reason, he roughed in where these objects were to be placed by marking the walls with a Sharpie ink marker, or something similar.
Folks – NEVER write on the wall with ink. Nor with crayon, ballpoint pen, or the like. The substances will eventually work their way through the wallpaper (as well as paint, wall texture, or a myriad of other surfaces), and will end up looking like ghost shadows.
Pencil is OK, and so is a light snap from a chalk line. These materials won’t bleed through the new top layer of wallpaper.
See that red vertical line just to the right of the paint can? The previous wallpaper installer had used a red Magic Marker to color the edges of his vinyl wallpaper. This is a good way to cover the white edges so the seams don’t show, especially with a dark paper. But it’s better to use chalk or colored pencils, because oil or ink can bleed through and will stain the new wallpaper or paint.
In this photo, the previous dark red wallpaper has been stripped off, but the red ink that was used to color the seam’s edges has soaked into the wall. The wall has been skim-floated with a light coat joint compound and then primed with the penetrating sealer Gardz. Yet the red ink has bled through. If wallpaper is hung over this red line, it is quite likely that, over time, the ink will work its way through the various layers and up to the surface.
The best way to prevent that is to use a stain-blocker. KILZ Original oil-based sealer and stain blocker is about the best product on the market for this. Brush it on, it dries quickly, and then you are safe to apply wallpaper, paint, or other materials.
KILZ will also block stains from oil, smoke, rust, water, ink, crayon, tobacco, and more.
