Ink Spots Bleed Through Wallpaper

July 8, 2018


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.

No more red spots showed their faces. 🙂

If You Want Smooth Walls, You’ve Gotta Put Up With a Little Dust

July 7, 2018


The walls in this house had a pretty heavy texture, which I wanted to smooth before hanging their wallpaper. This involves skim floating the walls with joint compound (commonly referred to as mud). Do a search on those terms here to learn more about this process.

Once the mud is dry, I sand it smooth. This makes a dust – and the thicker the wall texture, the more the dust. Here you see what has accumulated on the floor after sanding.

Don’t worry – I bring in my Shop Vac and clean all the dust up.

Someone Hung Wallpaper over Textured Walls

June 19, 2018

The texture on this wall is not heavy, but it can still be seen under the wallpaper. In the second photo, I am stripping off the wallpaper, and you can see the wall texture underneath.

I removed the top vinyl layer of the wallpaper, then removed the paper backing. Then I skim-floated and sanded the wall to smooth it (no picture). Follow up with a primer, and the wall was smooth as a baby’s bottom and ready for the new wallpaper.

Smoothing Textured Walls

June 16, 2018


I like walls to be nice and smooth when the wallpaper goes up, first so the texture doesn’t show under the new paper, and second so the paper has an intact, flat surface to grab ahold of. When homes have textured walls, I skim float them with joint compound (which we calls mud) to smooth them.

To skim float, I use a trowel to spread the smoothing compound onto the walls. In the top photo, the upper portion of the wall has been skimmed, and you can see the compound drying around the edges and in high areas. It goes on grey, and when it’s dry, it will turn white. The second photo shows the box that the mud comes in, enclosed in a plastic bag, to retain its moisture.

To help speed the drying process along, I set fans up blowing on the walls, as you see in the second photo. I have three fans, and they will be positioned differently for maximum air blastage. Having the air conditioner cranking away and the house fan on also help to circulate air and pull humidity out of the air. In small powder rooms where the door can be closed and the climate supervised closely, I get a space heater going, which also helps pull humidity out of the air. For stubborn areas, I get out the heat gun – it’s like a hair dryer on steroids. 🙂

Once the mud is dry, I sand the walls smooth, then vacuum up the dust that falls to the floor, then wipe residual dust off the walls with a damp sponge, and then finally prime the walls. For this application, I use Gardz, a penetrating sealer which soaks into the joint compound and binds it together, and which is also a good primer to hang wallpaper on. Sorry, no photo of the Gardz or of the finished wall – but you can Search here to find previous posts.

Rubbery, Problematic Smoothing Compound

June 15, 2018


I was stripping wallpaper by peeling off the top vinyl layer and then soaking the paper backing to reactivate the paste so the paper could be removed from the wall – and ran into this.

It looks like the previous installer smoothed the wall (which is good), but used a latex spackling compound instead of the more typical joint compound. The latex became wet from the water I was using to soak off the wallpaper, and began to pull away from the wall.

This is all bad, because it leaves a bumpy mess on the wall that will show through the new paper. But worse is that it is an unstable surface for the new paper to try to hold on to. When wallpaper paste dries, the paper shrinks and puts tension on the surface below, particularly the seams. If the surface is not solid, the layers can actually come apart (delaminate) resulting in curled or gapping seams.

This is not “loose paper,” and cannot simply be glued back down. The different layers inside the wall are actually coming apart, and will require a lot of work to make the wall sound again.

Once the paper was off and the wall was good and dry, the layers seemed to adhere to each other better, and the wall felt more solid. The way I treated it was to roll on a coat of Gardz, which is a penetrating sealer that binds things together. It did a good job. Then I skim-floated over that with joint compound, which, when sanded, would leave a nice, smooth surface.

One more coat of Gardz on top of that, and the wall was sound and ready for wallpaper.

Mildew, Bleach, KILZ

June 7, 2018


Whooah! I stripped off wallpaper from this wall around a window in a home that had some water damage from Hurricane Harvey, to find this black powdery stuff – mildew. You don’t want to put wallpaper over a wall that has mildew, because the black stuff will continue to grow. And because it’s chalky / powdery, it the wallpaper will not stick to it. And it will also work its way through the wallpaper and create a stain on the surface.

I use bleach to kill the mildew and remove it from the wall. Once dry, I use KILZ Original oil-based stain blocker to seal the surface. In this case, I also skim-coated the wall, to make it nice and smooth. I will follow that with a coat of Gardz, a penetrating sealer that is also a good product to hang wallpaper on.

Geometric Pattern in a Powder Room – Flooded Home

May 20, 2018


This home in the Energy Corridor area of Houston was flooded during Hurricane Harvey last August. A lower section of drywall had been cut out and replaced. The contractor’s wallpaper hanger put up this identical pattern. The homeowner wasn’t pleased with the job. To be honest, the installer did a pretty good job, in a room that was very difficult to hang. There were a few minor things that could have been done differently.

But what bothered the homeowner most was that the walls had not been smoothed properly before the paper went up. With that west-facing window blasting angled sunlight into the room, those irregular surface flaws were quite obvious. See the top two photos. (You may need to enlarge them.)

I stripped off the original paper and skim-floated the walls to make them as perfectly smooth as possible. I followed with a primer. (The previous installer had not primed the walls.) See third photo for walls that are ready to go.

This room was a major bugger bear to hang. For starters, there was a large metal mirror that protruded about 4″ from the wall, that could not be removed. This was directly over a pedestal sink. (The previous installer had the luxury of hanging the room before the sink was in place.) It’s hard to explain, but the logistics of winding wallpaper around these three-dimensional objects, preventing the paper from tearing, having the ridged and unforgiving pattern match on all planes, keeping the edges plumb, and keeping the edges straight so they would butt up with the next strip, all while fighting edges of the wallpaper that wanted to curl backwards, were extremely difficult.

In addition, the corners of the room were out of plumb, which pretty much guaranteed pattern mis-matches in all the corners. On a wild floral pattern, no one would notice. But with a geometric pattern like this trellis, the eye would catch even minor mis-matches.

Compounding all of that was the fact that nothing in the room was centered. The window was not in the center of the wall, nor was the toilet – and they were not aligned with each other, either. The sink was not centered on the mirror, the faucet was not in the center of the sink, and the spout was off-set from the handle. I finally decided to balance the trellis design on the mirror, and it did fall perfectly symmetrically on either side. The kicker is that the room is so narrow that you can’t stand back far enough to appreciate all my efforts. 😦

I probably spent 40 minutes plotting how to tackle the first wall, and then a full two hours hanging the first two strips (the ones around the mirror and sink) (sorry – the room was too small to get good pics). The longer I worked, the more appreciation I had for the previous installer and the job she had done.

In the end, the walls I had prepped were smooth, and there were no objectionable bumps or gouges showing under the paper. I pulled some tricks out of my hat and got the pattern to match in the corners pretty darned well.

That window with it’s danged strong light still was a foe, though. The wallpaper seams butted together just about perfectly. Yet because of the way the edges curled back when they got wet with paste, I fought to keep them down tight to the wall. Once dried, they were nice and flat. I was pretty content. But when the sun moved and light came through that window from a different angle – some of those seams looked positively horrid! The light was casting shadows and making it look like the seams were overlapped. Yet they were perfectly flat. The inclination is to go over and over the seams with various tools and try to “force” them to lie flatter – but this can burnish or otherwise damage the wallpaper or the underlying surface. The good news is that as the sun moved, and as the louvers on the shutters were adjusted, the shadows disappeared and the seams looked good.

Let’s hope that the homeowners see this room only in the most positive light. 🙂

This wallpaper is by York Wall, one of my favorite brands. Interestingly, the paper came with the correct label, but the instruction insert was for another line made by this same company. I’m glad that I was familiar with both products, and had the sense to disregard the info that was not relative.

Repairing Damage from Hurricane Harvey

April 27, 2018


This home in the Champions Forest area of north Houston received flood damage after Hurricane Harvey. The bottom 2′ or so of drywall had been cut out and replaced by the restoration contractor. The only thing is, the new drywall was recessed back about 3/8″ from the existing drywall. Even though this was near the floor in the niche behind the refrigerator, the homeowner didn’t want to have a difference in wall height, nor a mis-match in the wallpaper pattern.

So I used joint compound (“mud”) and drywall seam tape to bridge the gap and to float out the discrepancy. It took three coats, and several sandings, plus a sealing primer, but the finished wall is pretty even and smooth. (2nd photo)

There wasn’t enough left over paper to replace the whole alcove, so I used scraps to piece in the bottom area. Rather than make a straight horizontal cut 2′ above the floor, it’s less eye-catching to have the patched areas run along a feature of the design, such as the vines and branches in this pattern. (3rd photo)

Once the new strips were smoothed into place (4th and 5th photos), the patched areas are virtually undetectable.

Sometimes people complain about having left over wallpaper. But here’s a good example of why you should. (last photo) This homeowner had kept all her leftovers in their original wrappings and in their original box, in a climate-controlled environment (not the garage or attic), and she had what was needed to make this repair (and several others around the room that are not shown here).

Don’t Let The Contractor Prep the Walls for Wallpaper

April 18, 2018


This home was repaired after the flood of Hurricane Harvey. The contractor told the homeowner he would prep the walls for wallpaper. As you can see, his guys did get some parts of the wall nice and smooth. However, they didn’t bother to remove the mirror hooks, light sconces, or electrical switch plates. The result is some pretty gaps that will need to be filled in (by me) before I can hang the wallpaper.

Best to just let the Wallpaper Lady do the prep.

Heavily Textured Wall – Venetian Plaster

April 13, 2018


A few years ago, this wall finish was quite popular. There are different levels of thickness, but the general name for the style is Venetian Plaster. To me, this looks rustic and “Tuscan,” yet people were putting it in modern homes, and even Victorian styled homes. Today it’s out of style, and people are going back to wallpaper.

The walls will have to be smoothed again, before wallpaper can be applied. Because this particular example is especially thick, it will take a lot of smoothing compound and a lot of drying time.

The second photo shows the wall after I applied the smoothing compound. It had to dry overnight, with three fans set at ‘high’ blowing on it. In the third photo you see all the dust on the baseboard and floor, from sanding the wall smooth. This is way more than usual, because of the thickness of the original texture that I was covering up.

The last photo shows the wall after I sanded it and primed it. It’s now ready for wallpaper!
