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.
