Air Bubbles from Latex Paint

June 13, 2018

The walls had a light texture covered with latex paint, so I skim floated over the walls to smooth them. When the wet smoothing compound got onto the wall, the latex paint absorbed moisture, expanded, and created these bubbles. It’s called “off gassing.”

After the mud dried and was sanded, most of the bubbles disappeared, but some rings were still visible. When I primed with Gardz, a water-borne penetrating sealer, many of the bubbles raised their heads again.

I will have to see if they dry flat over night, or if I will have to use my putty knife to knock them off in the morning. I don’t want bumps showing under the new wallpaper!

Torn Drywall – Gardz Cures All

May 17, 2018

Wallpaper - Torn Drywall Repaired
When the wallpaper was stripped off the wall, some of the top layer of drywall came off with it. This is bad, because the inner layer that has been revealed will bubble when wet paint or wallpaper paste gets on it. Which, of course, looks bad under the new paint or wallpaper.

Gardz is a penetrating sealer that will soak into the surface, and then dry hard and impenetrable, allowing you to paint, paper, or, as in this case, skim-float over it with smoothing compound, without worries of bubbles or an unstable surface.

Gardz looks milky-white in the can, but dries clear. It is very thin and runny, so be sure to cover the floor and baseboards. In the photo, it has been applied to the lower left corner of the torn area.

The second photo shows the wall after it has been Gardz’ed, skim-floated, sanded, and re-Gardz’ed.

Cure Time – Paint Woodwork LONG BEFORE the Paper Goes Up

May 17, 2018


Why am I posting a picture of a can of trim paint? Because I found this in the room where I am to hang wallpaper today, along with a portable cup of wet paint and some brushes. This tells me that the homeowners were in the room last night, frantically painting all the woodwork in a large room with lots of framed openings and two walls of windows – LOTS of trim to paint.

Folks, this is not good. Woodwork should be painted carefully and slowly. First, the existing paint needs to be sanded or deglossed, and then wiped clean. I like to apply a coat of primer. Then the new paint can go up – but it should be brushed on carefully, paying attention to the direction of brush strokes and eliminating runs and drips.

But most important is that the paint needs time to dry. Not just to dry, but to cure. This can take several days.

This is important, because when I come along and put up the wallpaper, paste will get onto the woodwork. This is normal. No biggie. You just wiped it off with a damp rag.

But if the woodwork was not prepped properly, or if the paint has not had a chance to cure, it’s possible – probable – that the paint is not sticking tightly to the surface, and that wiping the paste off the woodwork will also take some of the paint along with it.

Best to plan ahead, read up on proper prep and materials, allow enough time to apply the paint properly, and then allow adequate dry / cure time.

Swirly, Cheery, Leafy, and Fun!

March 17, 2018


With drab murky blue paint and not much more, this powder room near the backdoor of a ’70’s era ranch style home in Candlelight Plaza (Houston) was serving its purpose. But the homeowner knew it could live much larger.

I skim-floated the moderately textured walls to smooth them, and then primed with a penetrating sealer called Gardz, which is also a good primer for wallpaper (see first photo).

The wallpaper pattern is called “Priano,” and is by Serena & Lily, and can be bought on-line. The design has a fun circular movement, and an organic leafy motif.

Farrow & Ball Paint on Wallpaper – Smudges, Splatters

March 13, 2018


Farrow & Ball is a British wallpaper and paint manufacturing company. They are unique in that, instead of using ink to print their wallpapers, they use their paints. It is a hand-screened process.

Any type of hand-done work means that there can be human error. (Well, you can have errors with machine-produced goods, too, but here we’re focusing on higher-end, artisan-inspired, hand-crafted goods.)

Anyway, here you can see a few smudges, and a few platters of paint on the wallpaper. All of these are considered typical and normal for a product like this.

While you are looking closely, I encourage you to notice the three-dimensional quality of the ink on the paper. It’s almost as thick as gesso. This gives the paper a subtle dimension, and ensures that every screen will be a tad different from the others.

Crusty, Flaky Stuff on Woodwork

March 2, 2018


You’re looking at a section of crown molding. See that flakey stuff? That is the enamel paint on cracking and chipping off the woodwork. Why? When the original wallpaper was installed, some paste got on the crown molding. This is normal.

But in this case, the paperhanger didn’t wipe off all the residue (this can be hard to do, because it’s really hard to see). Over time, that paste residue ate into the paint and caused it to crackle and chip off the wood.

This can be avoided by making sure that all paste residue is completely wiped off any painted surfaces. I like to use a thin blue plastic tape on the top edge of wallpaper, which keeps paste from coming in contact with the crown molding or ceiling.

Whoops – Somebody Painted Over Old Wallpaper – And It’s Peeling Up

February 23, 2018


This wallpaper is in the potty room of a Hollywood bathroom in a newish home in Bellaire (Houston). Instead of stripping off the original wallpaper, someone decided to just paint over it.

It’s not clear if they painted over the inked, vinyl / acrylic – coated surface, or if they peeled off that surface coat and then painted over the remaining paper backing.

Not that it would make a lot of difference, but they probably did not prime or seal the surface, either.

Either way, as you can see, the various layers failed, and the wallpaper seam let go of the underlying surface, resulting in the “popped” seam you see in the photo.

This probably has to do with a lot of factors, including an improperly prepped surface (read above), latex paint adding moisture that could cause the underlying surface to expand and swell, and humidity from the shower and the window allowing moisture to enter the edges of the wallpaper.

Once humidity enters the edges of wallpaper, it can cause the paper to expand and then pull away from the underlying surface. This can result in curled seams.

This is what you see in the photo above.

Improper Prep Leads to Failed Wallpaper Job

February 7, 2018


The new homeowners bought an adorable 1920’s home in the Woodland Heights neighborhood of Houston, and inherited a dining room with a beautiful wallpaper pattern – that unfortunately had not been hung properly. The wallpaper was curling at the seams, peeling away, and literally falling off the wall. It is taking chunks of a white substance along with it.

It’s hard to determine exactly what is causing the failure, but the first issue is that the underlying wallpaper was not removed. Since wallpaper has an acrylic coating, it does not provide a secure foundation for the new paper to adhere to. In some cases, it’s not possible to remove the old paper, and then the seams should be floated over, and the old paper should be primed so it will have a surface that the new paper can grab ahold of.

Here, it looks like the walls were either not primed at all, or were primed with a flat wall paint. Some of that paint is letting go of the old wallpaper and pulling away from the wall, which allows the new paper to fall off.

Ideally, that striped ’90’s paper should be stripped off, along with any other layers of paper underneath. But it looks like some of the underlying paper was floated over, and that makes it particularly difficult to remove.

I suspect there are other issues going on, so it will take some time and exploration to decide what will be the proper approach for removing the beige paper and then prepping the walls, before the new homeowners’ new paper can go up.

Wallpapering a – Doorbell?

February 6, 2018


In the top photo, you see the mechanism for a doorbell. I have hung grasscloth wallpaper behind it, and then replaced the doorbell.

I don’t like to put wallpaper on things other than walls, but I have to admit, the plastic cover to the doorbell, which had been painted with some blah flat wall paint, was sad and, well, unattractive.

So I primed the plastic housing and then worked with the stiff grasscloth to get it to wrap around the oddly-shaped box. It took a little persistence to get the grasscloth to stick to the curved box.

It was worth the effort. Once the housing was placed over the dingers, you could barely make out the shape of the cover.

Painters! Have Some Respect for the Homeowner’s Property

December 10, 2017


These homeowners’ home was damaged by flood waters in Hurricane Harvey. The wallpaper, drywall, and flooring in their Bunker Hill area townhome had to be ripped out and replaced.

After repairs, that means that everything in the room is new. Drywall, paint, sink, toilet, floor tiles, etc. It would be nice if people could KEEP everything looking new.

The homeowner asked me not to use the sink, because she already had to clean up messes left by the painters.

She might not have even seen these paint splatters on the floor. In the second photo, you see where the painters let their roller bang into the woodwork. These
dings” are small, but they are visible.

And they are sooo easy to prevent. All you need is a drop cloth. In addition, I like to tack an 18″ width of absorbant dropcloth fabric along the top of the baseboard, to prevent any spills or splatters from hitting the woodwork or the flooring.

It takes very little to protect a homeowner’s moldings, floor, and countertops.
