Smoothing Walls – I Can’t See What I’m Doing!

September 15, 2021
To smooth textured walls so you won’t see bumps under the wallpaper, I use this trowel to spread on Sheetrock brand Plus 3 lightweight joint compound (a.k.a. “mud”). This is called “skim-coating” or “skim-floating.”
Problem is, the mud is the same color as the wall. I can hardly see what I am doing! Once it dries it will turn white. But until then, I’m fumbling along.

Smoothing Suburban Heavily Textured Walls

November 1, 2020


In the tract homes in new subdivision developments all around Houston, it’s very common that the builder will use a heavy wall texture like this. You can’t hang wallpaper on this, because the bumps and dips will look horrible under the paper, and also they will impede good adhesion.

So the walls will need to be smoothed. This is accomplished by “skim-floating” or “skim-coating” the walls with joint compound. I do my own prep. And, as I like to say, I’m better at it than any “guy” you can hire. 🙂

The third photo shows the wall with half in original condition, and half with the smoothing compound applied over it.

Some people use a wide taping knife to spread the “mud,” as we call it. But I prefer the trowel shown in the fourth photo, because I am closer to it and can see everything that I am doing, and also I feel the position of the handle gives me better manual control.

Sometimes, using fans and playing with the A/C or heat systems, the compound will dry in a couple of hours. But with texture this heavy, the material must be left to dry overnight.

Tomorrow morning, I will sand the walls smooth, vacuum up the dust, wipe residual dust off the wall with a damp sponge, and then roll on a primer. Once that dries (again, call in the fans!), the wallpaper can go up. The second-to-last photo shows it finished and ready for wallpaper.

The last photo shows the brand I prefer, USG’s Sheetrock brand “Plus 3,” which you can find at most big box stores and most paint stores. It sands a lot more easily than the standard joint compound in the red, white, and green box.
