Stripping Wallpaper

January 30, 2020


Eeewww – I’m stripping wallpaper off the walls of a bathroom. What a mess!

(Don’t worry – there are dropcloths under there.)

For a few years now, I’ve been using Roman’s Pro 977 Ultra Prime wallpaper primer, and this was my first chance to remove paper that has been hung on it. I must say – I was very pleased.

The paper came off nicely enough, and the primer stayed stuck to the wall. It did not rewet or bubble. There was NO damage to the walls, and no need for repairs, nor any need to reprime.

One key to this is to wet-strip the paper. You cannot come in and just try to yank the paper off the wall. First of all, that won’t work. But if it does, it is likely that the paper will take some of the primer and even some of the wall or drywall along with it.

The proper, more gentle way to strip wallpaper is …

You’ve gotta understand that wallpaper is made of at least two layers – the top, inked layer, and the underlying substrate layer.

I use plain water and a 3″ stiff putty knife to strip paper. The water will re-wet the paste on the back of the paper, and once it is wet and softened, the paper will (usually) peel away from the wall easily and in large pieces.

The thing is, water will not penetrate the top, inked layer of wallpaper. That’s because the manufacturer has applied a coating to protect the paper from stains, and it is resistant to water.

So I take that putty knife and use it to get under the top layer of wallpaper – withOUT gouging into the substrate or into the wall. Then I peel off that top layer of paper. I have found that wetting the surface with a sponge helps strengthen the fibers, so that larger chunks of paper come off. You will also find that there is a “nap” to the material, and it will pull off in larger chunks once you figure out if it wants to be pulled from top to bottom and / or from left to right – or vise versa.

It will separate and leave the backing / substrate stuck to the wall.

Once that top layer is off, I use a sponge and a bucket of hot water to wet the backing. Over and over as needed. The backing is porous and the water will soak through, allowing the paste to reactivate. Once that paste gets wet enough, it will let you pull the backing away from the wall.

You will have the most success with this if the walls were properly prepped and primed before the original wallpaper went up.

That’s it in a nutshell. Time consuming, but sort of methodic and meditative. And it will leave your walls in good condition to receive the new wallpaper.

Wild Wallpaper In Frames That Will Be Hung On The Wall

July 31, 2018



Here’s some really cool, custom-made wallpaper that, expectedly, costs a ton. The homeowners wanted to accentuate two rooms (dining room, master bedroom) with these patterns, but, considering the investment, wanted to be able to take it with them, should they move.

After much deliberation and investigation of backings, weight, sturdiness, etc., it was decided to mount each mural on plywood, wrap each of those with a wooden frame, and then mount them on the walls with brackets that attach invisibly to the back.

The largest one, which already has its frame attached, and which you see in the top photo, measures about 7′ x 7′, and weights 80 pounds. Imagine getting that thing up two flights of stairs!

The top photo shows the large mural finished. It consists of two panels spliced in the middle. It was trimmed in place to fit inside the gold frame you see around it.

The second photo shows the smaller mural being laid out. It will be applied to the board you seeing lying on the floor in the third photo. The plywood board has been sealed with KILZ, to prevent knotholes from bleeding through, sanded smooth, and then primed with a wallpaper-specific primer. I used Roman’s Pro 977 Ultra Prime.

These wallpaper panels are custom-made to fit the project’s dimensions, and have a few extra inches “bleed” area on each side to allow for trimming and adjusting for wonky walls. The bordering silver area will be trimmed off, as will an inch or so of the printed area on each side of the mural.

On the smaller, dark mural, someone forgot to add an extra inch for the top and bottom, so the mural was centered as perfectly as possible, but a little bit of the white plywood peeked out on both the top and bottom. Don’t worry – a black frame will be constructed to cover the edges of the plywood, and it will have a lip (rabbet) that will cover this teeny gap.

The last photo shows one page of the instruction sheets, which includes drawings from the manufacturer detailing the layout and dimensions of each mural. The large mural came in two panels, which had to be overlapped in the center, carefully matching the pattern, and then double cut, or spliced.

Double cutting involves overlapping the edges of the two strips of wallpaper, while carefully matching the pattern. Then you take a straight edge and a brand new, very sharp razor blade and cut through both layers of paper. This paper was very thick, so I had to press really hard to get through both layers in one sweep. You want to avoid making multiple cuts if possible.

To keep from scoring into the plywood below (and it’s even more important if you are cutting on a wall made of drywall and / or many layers of paint and primer), I put a strip of polystyrene plastic on the plywood surface to keep the razor blade from cutting into the bottom surface. Once the double cut is made, the excess wallpaper, as well as the polystyrene strip, are removed, and the two edges of wallpaper smoothed into place. This makes for a very perfect seam.

All this takes a lot of time. It would be really cumbersome in a larger or more complicated room. But protecting the subsurface is important, because, once the wallpaper starts drying, it shrinks a little and pulls taught, and if the surface below is not intact (due to a cut from a razor blade, or from something else like dust on the surface or layers of incompatible materials such as old oil based paint covered with latex paint), these layers can come apart (delaminate), and the wallpaper seams will pull apart. This is not the paper “coming loose,” and it cannot be “glued back.” It is actually layers of the wall delaminating.

Anyway, back to today’s project, and, sorry, a little out of sequential order, but all important information. These panels were to be hung on the walls, but had not been hung yet. This allowed me to do them flat on the floor, which I think was easier. The instructions said to paste the paper, but that was extremely difficult because they were much wider than my work table. I didn’t want to crease or damage the material. Most non-woven products can be hung by pasting the wall, so that’s what I opted to do. Except, in this instance, they were laid out on the floor. 🙂

The material was a thick non-woven on a mylar plastic, and was very thick and somewhat difficult to work with. In addition, the panels were much wider than normal wallpaper, and hard for me to manipulate. I was glad that the interior designer was hanging around and was game for helping me position these pieces.

As I said, the material was thick and stiff, and no matter how hard I pushed or what extreme tool I used (metal plate), it would not press tightly into the corners of the gold frame enough for me to get a satisfactory cut – meaning that there was a slight (1/16″ – 1/8″ gap between the material and the frame. No matter… The interior designer was easy going, and said she will add a small piece of molding to the inside of the gold frame, to cover any gap, as well as to prevent the thick material from curling up. On the smaller, dark mural, the black frame to be constructed will include a lip (rabbet) that will cover the open edge and help hold it down, as well as cover the outside edge of the plywood panel.

This gutsy wallpaper is made by Calico, a husband-and-wife team out of New York City that is just a few years old – not many people have this stuff – and even fewer have the balls to put it on their walls!

The interior designer for the project is Elizabeth Maciel, and the location is a newish home in the Montrose neighborhood of Houston.
