Thin Blue Plastic Tape Keeps Paste Off The Wall

August 7, 2022
Panel of wallpaper lying on my pasting table. The left edge will go up against a painted wall that is not to be wallpapered. It’s important to keep paste off this wall, because the paste can cause the paint to crackle and flake off. Yes, you can wipe paste off the wall, especially if it’s a gloss paint. But better to not get paste on the wall in the first place.
So I’ve placed a strip of this cool blue plastic tape along the edge. It sticks to the pasted wallpaper, but will not let paste get onto the wall.
Here is the wallpaper in place, with the little 1″ overage wrapping onto the wall to the left. See how the blue tape is preventing paste from getting onto the wall?
Once I finish trimming, I will remove both the excess paper and the blue tape. Be sure to remove any blue tape that is still behind the wallpaper.
This also works for ceilings and for abutting another strip of wallpaper.
This tape is much better than painter’s plastic or ” caution tape ” because it is lightly tinted so you can see it, it’s translucent so you can see through it, it has the perfect body – thicker than painter’s plastic but more flexible than caution tape, and has a unique textured surface that makes it handle nicely, plus you can easily snap it apart so there is no need for scissors or razor blades.
It’s made in Japan and tricky to get. If you’re interested, email me at wallpaperlady@att.net and I’ll hook you up with the supplier.
The very edgy wallpaper? It’s by Spoonflower and called Serpents and Apples .

Sneaky Snaky Dining Room Accent Wall

August 6, 2022
Beautiful symmetry …
But look closer – those intertwining lines aren’t fronds of vegetation – they’re snakes !
The wall before. It’s a mid-century home, but the drywall here is new. Per my request, the contractor left it taped and floated , but not painted or covered with any coating .
I had planned to simply prime this wall. But after examining it more closely, the surface was a little grittier than I like. So I ended up applying a very light skim-coat and sanding it smooth .
Here the smoothed wall has been primed with Roman Pro 977 Ultra Prime .
I’m plotted out the center of the wall and am using my laser level to ensure that the design in my first strip falls right along the center, and also is nice and plumb .
My work table with two strips of wallpaper . Spoonflower packages its wallpaper differently from other companies. It comes in widths of 24″ and lengths of your choice of 3,’ 6,’ 9,’ or 12.’
Get their Pre-Pasted Removable Smooth option, which is water-activated , and is wonderful stuff.
Do NOT get the Peel & Stick , nor the Traditional Pebble . The P&S and the Traditional are both very difficult to work with, and can lead to bubbles and creases on your walls , plus cause damage when the wallpaper is stripped off later.
Back to the photo – the blue cube thing in front is my laser level , shooting its red line at the wall.
Close-up
I’m using this blue plastic tape on the edge of this strip of wallpaper. This will prevent paste from getting onto the wall or ceiling.
The accent wall stops in this left hand corner, so I need to trim off the excess. But I don’t want to get paste onto the un-papered wall. Paste can cause the wall paint to crackle and flake off.
So here you see how the blue tape is keeping paste off the wall. Once I finish trimming, I’ll check the back to make sure all of the blue tape has been removed. Any areas where the blue tape might be still on the back of the wallpaper , the paper won’t adhere to the wall .
This tape is available to paperhangers / installers . If you’re interested, shoot me an email wallpaperlady@att.net
Another thing about Spoonflower , the seams are meant to be overlapped, by 3/4″ . Note that this does create a ridge that runs vertically the length of each seam. In the grand scheme of things, this isn’t very noticeable.
Actually, there are advantages to overlapping seams in this manner. No worries about white substrates showing at the seams, nor the paper shrinking and leaving gaps at the seams.
Also, in case of unstable walls that might come apart ( delaminate ) under the tension of the drying / shrinking wallpaper, overlapping disperses the tension and helps prevent wall failure.
This pattern is called Serpents and Apples and is by Spoonflower . Spoonflower has a lot of cute designs , and also a good number of fun avant garde patterns like this one.
The homeowners have some other non-typical d├ęcor that will meld perfectly with this wallpaper. Think life-sized skeletons .
… Notice how that light fixture hanging in the center of the wall kinda looks like a skull ? …
The home is in the Oak Forest area of northwest Houston .

Whoops! Someone Painted Over Old Wallpaper

April 21, 2021

Just looking at the walls, I had not noticed . But when I removed the light switch cover, it was clear that someone didn’t bother to remove the old wallpaper, and just painted over it.

Actually, they probably did do some prep, because you could not see seams under the paint. They must have taken steps to cover the seams.

And there was no flashing … difference in texture between paint over wallpaper, for instance, and paint over smoothing compound that was used to disguise those seams.

And there were no bubbles (caused by latex paint on top of wallpaper that absorbs moisture from the paint and swells) and only a few tiny loose areas.

Still, it would have been better if the previous guy had put some effort into removing the wallpaper, and then washing the paste off the wall and then sealing with a stain blocker, to prevent paste residue from causing the new paint to crackle and flake off the wall. Then the room would be adequately ready for paint.

Doing the Opposite Today – Removing Wallpaper

September 30, 2020


The large medallion on soft lavender on all walls of this large bedroom worked well for this gal for many years – but now that she’s an older teen, it was time for an update.

So instead of putting wallpaper up, today I took it down.

Most people think that stripping wallpaper is difficult. But if the walls were prepped properly, and if the paper was hung properly, and if the proper removal steps are followed, it should all go well, with minimal damage to the walls. See my link at right, on how to strip wallpaper.

The most important thing is to separate the top, inked layer of paper from the backing / substrate layer. I find that wetting this top layer with a sponge and plain water helps strengthen the fibers, so the top layer can be pulled off in larger strips.

In the second and third photos, you see how the purple layer has been stripped off, leaving the white backing attached to the wall. This top layer has to be removed, because it has an acrylic (or vinyl) coating, and will not allow water to pass through it.

The next step is to soak the backing with plain water and a sponge (see photo). No chemicals, no additives – just plain warm water. You will have to reapply water several times. The idea is to let water soak through this backing layer, to reactivate the paste underneath. Once that paste is good and wet, it should release from the wall. Sometimes you have to gently scrape the backing from the wall. But in my case today, once that paste was reactivated, the substrate layer came away from the wall in full, intact sheets. Easy peasy!

One photo shows my “dull” 3″ stiff putty knife. I call it “dull,” because it’s old and beaten up. But it’s really rather sharp. I use it to carefully get between the inked top layer of wallpaper and the bottom substrate layer. And then I use it to gently scrape wallpaper from the wall.

In my case today, the previous installer had done a superb job of hanging the wallpaper. He applied a primer before hanging the paper. That primer helped make this whole removal job go well, and it protected the walls from damage.

The family will need to apply a stain blocker to prevent any residual paste from causing the new paint from crackling or flaking off. Once that’s dry, the walls can be textured and / or painted. The room’s resident told me that she is planning to go all white.

This home is in the West University area of Houston.

Keeping Paste Off The Paint

March 10, 2020


My next strip of wallpaper will be placed to the right of the strip in the photo, and it will need to be trimmed horizontally along the rounded (bull-nosed) edge of the wall.

To keep paste from the wallpaper from getting onto the wall paint during trimming, I have placed special 2″ wide, thin blue plastic tape along the edge of the wall.

Once I have finished making my trim cuts, I will remove the blue tape. There will still be sufficient paste on the wallpaper to hold it to the curved edge.

No need to wipe anything, no paste on the paint, and no worries about paste causing the paint to crackle and flake off the wall down the road.

David Hicks’s “Hexagon” in a Master Bathroom – Note the Freestanding Bathtub

March 15, 2019


David Hicks’s “Hexagon” pattern by Cole & Son is a well-loved design. I’ve hung it a number of times. Here it is in a large master bathroom in a very Mid-Century Modern home in the Piney Point (Villages) neighborhood of Houston.

Just this bathtub alcove, along with two small mirror walls over the his-and-hers vanities, received wallpaper.

Just the tub alcove by itself took me over six hours to hang (six single rolls). The complicating issues were unplumb walls, unlevel ceiling and soffit, a geometric pattern that the eye wants to see marching evenly across the walls, thick stiff paper that is hard to manipulate, ink that wants to crack and flake off the paper, complicated room lay-out, and … squeezing behind that tub to put wallpaper on the walls around it!

There are some spots where the pattern match is off a bit, and some areas where the crookedness of the walls is very evident (meaning that the pattern goes off-kilter). But overall, the room turned out great.

The design is called “Hexagon,” and is by David Hicks, designer for Cole & Son, a British company who has been manufacturing wallpaper for way more than a hundred years.

It’s a non-woven material that can be hung by the paste-the-wall method, but I chose to paste the paper, which made it more pliable, and which made it easier to get paste where it needed to be when going around the window areas and behind the tub.
