Short answer
Skim coating in Naperville means troweling one to three thin coats of joint compound over an entire wall or ceiling, then sanding it flat for paint. Fixr publishes $.90 to $1.30 per square foot for skim coating, with walls at the lower end and ceilings higher.
Why a skim coat beats patching a textured wall
Spot repairs on a textured or damaged wall never fully disappear, because the patch is smoother or rougher than everything around it, and side light from a window finds it.
A skim coat resets the entire surface. Thin coats of compound fill the texture and blemishes, and sanding brings the wall to one flat plane. Once primed, it takes paint like new drywall, in any sheen.

- Level 5 finish under glossy or dark paint
- Room height and furniture to protect
Patch, skim or Level 5: matching the work to the wall
Not every wall needs the full treatment, so here is how the levels of work line up.
| Approach | What it fixes | Best under | Effort |
|---|---|---|---|
| Spot patching | Holes, dents and small cracks | Flat paint on busy walls | Low, quick fill and sand |
| Single skim coat | Light texture and minor blemishes | Matte and eggshell walls | Moderate, one coat and sanding |
| Full Level 5 skim | Heavy texture, torn paper, wavy seams | Satin, dark colors, strong side light | High, two or more coats |
| New drywall over old | Badly damaged or crumbling surfaces | Any finish | Highest, new board and taping |
Orange peel to smooth
Orange peel is the light, dimpled spray texture found on a lot of drywall from the 1980s and 1990s. It hides minor flaws, but plenty of people now want the clean look of a smooth wall. We knock off any high spots with a pole sander, prime if the paint is glossy, then trowel compound across the wall to fill the dimples. A second, thinner coat goes on after the first dries. Sanding under a work light finds the low spots before primer, and the wall is then ready for a modern flat or eggshell.
Level 5 finish
Drywall finishing has levels set by the industry, and Level 5 is the top one: a thin skim of compound over the entire surface after the taping and coating are done. It exists because strong side light, glossy paint and dark colors expose the difference between paper and mud. Tall walls with windows along them, great rooms and long hallways are where it pays off. The skim is troweled on, or rolled on and pulled down with a wide blade, then sanded lightly and primed so the paint lays down even.
Torn paper facing
Torn brown paper shows up after wallpaper comes off a wall that was never primed, or where tape and anchors were yanked out. Water-based compound on torn paper makes it bubble and lift, so the first step is sealing every tear with a shellac or oil-based primer. Loose flaps get trimmed with a sharp knife. Only then does the skim go on, usually two coats, sanded between. Skipping the seal is a common reason a skimmed wall blisters a week later, and once it does, the bubbles have to be cut out.
What a skim coat job includes
These steps are part of the job unless we agree otherwise.
- Covering floors and wrapping furniture
- Sealing torn paper and knocking down texture
- Two or more thin coats where needed
- Sanding with daily dust cleanup
- Primer over the finished skim
- A final check with you in good light
Ranches, split-levels and historic-district plaster
Single-family houses in North Naperville are mostly mid-century ranches and split-levels with newer traditional builds mixed in, so the same few blocks can hold decades-old patched drywall and newer sprayed texture. The Naperville Historic District adds another kind of wall: its federal listing first covered buildings from 1927 and earlier, and a 2012 update added contributing properties built through 1962. Skim coating works on sound plaster as well as drywall, which makes it a gentle way to smooth an old wall without tearing it out.
From textured wall to paint-ready
- Protect the room. Floors covered, furniture centered and wrapped, doorways masked off.
- Seal and knock down. Tears sealed with shellac primer, high texture sanded off.
- Skim coats. One to three thin passes troweled across the full surface.
- Sand and check. Sanded smooth, then inspected under a raking work light.
- Prime for paint. A drywall primer evens out absorption before color goes on.
