Odd Pink Tint

December 7, 2022
On the inner portions of these rolls of embossed vinyl faux grasscloth , but only on the outer edges , was this odd pink tint .
It seems to be only in the center of the roll – closer to where it was wrapped around a rod, perhaps?
It seems to be only on the outer edges .
This is disconcerting, because there are substances that can bleed and stain wallpaper, and vinyl is especially prone.
This shade of pink happens to be the same as mold , which will stain and grow … but it doesn’t fit the irregular growth pattern of mold.
I’m hoping it’s something from the factory that that is harmless, like a water-based paint or pigment that got onto the rolling apparatus and transferred to the paper, or some other innocent anomaly .
It didn’t appear to have infiltrated the vinyl surface of the material , so I went ahead and hung the paper . Let’s keep our fingers crossed that this substance remains inert , and the wallpaper looks pristine for years to come.

Tinting Primer So I Can See It

September 6, 2022
With so many homes having white walls these days, I was having a hard time seeing where I had applied my wallpaper primer – which is also white. So these days I have the paint store add just the minimum of color to the can.
This helps me see where I’ve spread the primer, but still allows for a crisp near-white base for the wallpaper to sit on.
It’s important not to add too much pigment, or it will interfere with the primer’s ability to do its job. The label will spec how much pigment is O.K.
I like Roman Pro 977 Ultra Prime , which is made specifically for use under wallpaper.
Although Sherwin-Williams stores can get this, not all of the store managers will . So I was happy when Murphy Brothers on Bissonnet , not too far from me, was able to stock it – just for me.
Note: This stuff ain’t cheap – more than $60 a gallon ! That’s almost as much as a 5-gallon bucket of wallpaper paste .

Dark Wallpaper – Preventing White Gaps Showing at Seams

February 24, 2022
Dark papers are popular right now. But since wallpaper shrinks a tad when it dries, and since it’s usually printed on a white substrate, it’s possible that hairs’-breadth gaps of white wall may show at the seams. One way to prevent that is to stripe the wall under where the seams will fall with a color similar to the background of the wallpaper. Be careful to not get it too dark, as too much pigment may interfere with the wallpaper primer’s ability to perform optimally.
I measured the width of the strips, and then used a laser level to guide my stripes.
I use craft paint from the hobby store, and daub it on with a scrap of sponge (right) and dip into a bit of water, which I keep in a Gatorade bottlecap (left).
To get rid of the white edges of the substrate, I use a bit of chalk (some folks use paint – but make sure it’s water-based …. NEVER use oil-based paint, markers, or chalks, as they will bleed onto the surface of the wallpaper). I run the chalk along the edge of the wallpaper strip, making sure to work from the back side, to prevent the chalk from working its way onto the surface of the wallpaper. Use a light touch, but cover all of the white edge.
