Potential Trouble Brewing

July 7, 2019


What you see here is a bit of rubbery latex paint and texture that has peeled away from the wall in this powder room. The surface underneath it felt gritty and dusty and porous. I had the feeling that if I had tried, I could have peeled all the paint off the wall.

This is not good.

This paint is probably peeling because of a combination of poor quality materials (cheap paint), improperly prepared surface (inappropriate or no primer, not removing dust from the wall, incompatible coatings (latex over oil based, not sanding or deglossing a gloss paint before repainting), climate fluctuations (humidity, temperature), stress on the wall (pulling off a piece of tape), or more.

All this is not so bad under paint, because paint just kinda sits there on the surface. But wallpaper actually puts stress on the surface beneath it, as it dries and pulls taught. Over time, fluctuations in humidity and temperature can exacerbate that, causing the paper to expand and contract ever so slightly, and then put tension on the wall where the seams fall.

This can result in not just the seams coming loose, but in the various layers inside the wall actually delaminating and coming apart from themselves.

Disguising a Utility Box

January 21, 2019


Look closely – VERY closely, and in the upper half of the photo, you’ll see a metal utility box that has been covered with wallpaper.

This is a box for a defunct and un-used security alarm system, about 18″ square. The homeowners tried to get the box off the wall – but, despite the use of various screwdriver bits and power tools, the box would not come off.

So they were going to be stuck with a grey metal blob in the middle of their beautiful wallpaper.

Well, I thought I could do something with it. I could make it fade into the background of the wallpaper pattern.

Wallpaper won’t stick to painted metal, because it’s glossy. So I took a bit of sandpaper to knock off the gloss, and my primer Roman’s 977 Ultra Prime and coated the service box.

Then I matched the wallpaper pattern to the paper already on the wall, and covered the box with corresponding wallpaper.

This is more tricky than it sounds, because the box is 5″ deep, which created discrepancies in the pattern match, depending on from which angle you are looking. I opted to keep the pattern matched at the corner junctions rather than matching it as it would be view from a distance on the wall. That all gets too complicated to try to explain here.

The box had been primed, so it provided a good base for the wallpaper paste to stick to. But on some areas, like the edges after an outside corner, I smeared on a bit of clear adhesive caulk, to be sure the paper would hold, even under conditions of stress such as wrapping around a corner.

This whole thing took me 45-60 minutes. I am pleased with the way it turned out. From the floor, you sure would never know there is a large box sticking out of the wall.

Loose Wallpaper; Wall Layers Delaminating

November 15, 2018


Look closely between the seam of the wallpaper in the top photo. You can see little crumbly things. In the second photo, the issue is even more pronounced.

This is in the upstairs bathroom of a 1950 house in central Houston. Over time, compounded by humidity, poor air circulation, poor air conditioning / heating, and possible influences from the outdoors, various layers inside the wall have let loose of one another.

What are these layers? Originally the walls were probably painted with oil-based paint. Over the years, layers of latex paint, gloss paint, joint compound, and etc. were piled on, probably without proper prep between coats.

Some of these materials are not compatible with one another, and, over time and with stressers like humidity, they can let go of one another.

If just the wallpaper has come loose, as in the second photo, it can be pasted and readhered. But when the wall itself is coming apart, there is no fix, other than to scrap everything down to the original drywall (huge mess) or go over everything with 1/4″ drywall.

In this case, the homeowner had me repaste the few loose areas of paper, and then chose to live with the other visible cracks, chalking it up to an old house full of character and quirks.

Leopards Walk the Room Right

August 19, 2018


I’ll be the first to admit – I love a darkly decorated room. But this all-black powder room in the home of a young couple in the Heights neighborhood of Houston was not making the grade. With shiny black paint on all four walls, there was nothing to define the room. You literally could not even see where one wall ended and another began. And the work had been done poorly, with zillions of bumps and bits of stuff stuck in the paint.

My first task was to use Liquid Sandpaper to degloss the shiny paint. Then I skim-floated the walls to smooth over the irregularities. Sanded smooth, wiped off the dust with a damp sponge, then primed with the penetrating sealer Gardz. Sorry, no pic of the prepped walls.

The new homeowner was fine with the dark idea, but she wanted something fun and a little sassy, that would wake you up when you walk into the room. These marching rows of leopards do just that!

The new wallpaper is still dark. But not quite as dark. And because it has pattern and some variations in color, you can easily see the corners, and each individual wall. The room is no longer stark and oppressive, but warm and fun.

This wallpaper design is called Leopard Walk, and is by Cole & Son, a British company. It is a thin and flexible non-woven material with a vinyl surface that will resist splashes and stains better than most papers.

Why Is This Paint Peeling?

Here you are looking at woodwork in a home that has been freshened, at least one time, with a new coat of paint.

But, as you can see, the new, top layer of paint is starting to flake and peel up. Why?

Paint that is used on woodwork is usually semi-gloss or even high-gloss. Glossy finishes have a slick surface. And just as nothing sticks to dust, nothing sticks to gloss.

What’s happening here is that the top layer of paint is peeling away from the bottom layer, because it has no texture, or other rough surface to “bite” into. Depending on how glossy the sub surface is (the original painted woodwork), the new paint may stay on the molding forever, or it may give way immediately, or it may peel up bit by bit, as you see here, as it becomes stressed or injured.
