Skim-Floating to Smooth a Textured Wall

January 25, 2023
Wallpaper is to go on the top 2/3 of the walls in this large dining room. But the walls are textured, and that texture will show through the new paper. Which looks pretty bad , IMO , especially since most the design is plain white background. So here I am applying a skim-coat by skim-coating / skim-floating the wall to smooth over the texture.
Close up. A lot of people use a wide broad knife or drywall taping tool . But I prefer the control I have using this trowel . There will be ridges and valleys and imperfections . But tomorrow, when the smoothing compound is dry , I will sand everything smooth . I have to say, I’m pretty darned good at smoothing walls . 🙂
I like to use the Plus 3 Joint Compound by the Sheetrock brand. It’s much easier to sand than the standard joint compound . Do NOT use the ” quick set ” version – coatings such as primer , paint , or wallpaper don’t like to adhere to this stuff . It’s made for small patches , not covering entire walls. BTW, for short, we simply call this ” mud .”
Once the walls have been sanded smooth , all the dust vacuumed up, and residual dust wiped off the walls with a damp sponge , then I will apply my favorite primer, Roman Pro 977 Ultra Prime , made specifically for use under wallpaper .
