Ensuring Smoothing Compound Will Adhere to Glossy Surface

March 15, 2023
This wall has a texture on it that will look bad under the new wallpaper, and it will also interfere with adhesion.  So the wall needs to be skim-coated / skim-floated to smooth it.  But the current paint on the wall is glossy, as you can see on the right side of the photo.  The smoothing compound is sticky stuff, but it (like many coatings) cannot be trusted to adhere to a shiny surface.  I say it’s like the toy Colorforms … the new material will kinda stick – but not really stick .
But if the surface is dull , or matt finish , the new coating will be able to grab ahold and adhere .
To make this wall surface dull , I’m rolling on a primer that will dry with a flat / matt finish . 
There are various primers out there that will adhere to a glossy surface and then dry flat.  But I’m using my trusty wallpaper primer , Roman Pro 977 Ultra Prime .  Yes, this is a wallpaper primer .  But it also checks all the boxes … it sticks to just about anything , it dries quickly, especially with a fan blowing on it, and it dries with a matt finish that wallpaper paste – and smoothing compound  – will adhere to.  At $70 or more per gallon , yes, this stuff is expensive .  But it works , it’s low odor ,  it’s already on my truck , and it saves having to carry around an assortment of of primers and materials.  
Here’s my smoothing compound.  Sheetrock brand Plus 3 joint compound used for working with drywall .  Note that quick-dry formulas , nor spackling compound , are not suitable and won’t hold up under wallpaper .  You can search here for my other posts to see more about the smoothing process for textured walls . 

More Peel & Stick Hate

January 17, 2023
so-called peel and stick wallpaper is not nearly what the vendors’ websites make it out to be. It is neither easy to install , nor easy to remove . Nor does it hold up very long. I won’t hang it, neither will most of my colleagues across the country. Even our British counterparts have asked us to not let it slip across the pond!
I won’t work with it, but one of the clients I visited yesterday did attempt to DIY try it on her own, with quite unsatisfactory results. She was kind enough to let me take photos .
Here you can easily see wrinkles next to the door molding .
gap at seam over door, warps along side door.
hard to see, but there are large wrinkles. Plus notice on the right, paper is not adhering to the wall.
seams shrink and gap.
P&S material is not even trying to adhere to the wall.

A lot of these failures are due to the homeowners’ lack of knowledge and experience with peel & stick , and with wallpaper in general. For instance, the textured walls should have been smoothed / skim-coated / skim-floated before applying the material . Wallpaper wants to adhere to a smooth surface – not to the “highs and lows” of a textured wall .
Next, most P&S instructions call for application on a semi-gloss paint , which needs to cure for 6-8 weeks.
Also, read the fine print, and you’ll learn that P&S is meant as a temporary wallpaper …. you can plan on it starting to fail in less than a year. That’s where you get the failure to stick to the wall , and shrinking at the seams . Of course, here you can see that that happened within a few weeks / days.
In this case, the material will be easily removable from the wall. But in most cases, if you’ve installed it on a smooth , primed wall, well, when stripped off, it will take the paint along with it. Leaving you with a nasty , pock-marked mess to have to repair. Click the link to my page on the right, about why to stay away from P&S.

Soft and Sweet Pattern for Accent Wall in Baby Girl’s Nursery

November 24, 2022
The crib will go on this wall. Originally it was textured grey paint , as you see on either side .
Here is the wall after I’ve skim-floated / skim-coated it, sanded smooth , and primed with a wallpaper primer called Roman Pro 977 Ultra Prime . I have them put a little blue tint in it, so I can see where I’ve rolled it on.
This wallpaper comes in one continuous roll ordered by the yard , as you see on my table , as opposed to double roll bolts as most brands are packaged.
This cute pattern is called Thatcher . It looks like a simple repetitive pattern , but it was actually fairly complicated . Not all those starburst motifs , and especially not the fan shaped lines around them, are the same.
Looks hand painted with a paintbrush .
The paper has a clay coated surface , which give it a beautiful matt finish.
It’s lovely stuff to work with – seams melt away like butter , and trim lines are spot-on. (Many companies’ are not.)
This brand’s papers come with an unprinted selvedge edge that has to be trimmed off by hand.
You use a straightedge and single edge razor blade , and follow the manufacturer’s trim guide lines , to remove the selvedge. Today trimming this one bolt to do one wall took a full hour.
The brand is Pepper Home .
The home is in the Woodland Heights area of Houston .
