You’ve picked out the perfect paint color, and you’re ready to give your walls a fresh look.
But while you might be tempted to slap some paint over imperfections, nail holes, and dents, that’s not a great idea — those eyesores will still be there when the paint dries. Fresh paint can even make uneven surfaces more obvious than they are now.
That’s why it’s a good idea to start the project with any necessary drywall patching or skim coating. They’ll help you get a smoother, more even finish from your new coat of paint.
The Importance of Making Drywall Repairs Before Painting
There’s no doubt about it: a fresh coat of paint can completely change the look and feel of a room. But it can’t fix imperfections underneath.
Skipping this kind of important prep work can lead to a number of issues, including:
- Visible Imperfections: Holes, dents, and rough patches can cast small shadows, particularly when sunlight hits the wall at an angle.
- Uneven Texture: Poorly blended repairs can leave raised edges or smooth spots that stand out against the surrounding wall.
- Inconsistent Sheen: Joint compound absorbs paint differently than previously painted drywall, which can cause the repaired areas to look duller or shinier.
- Recurring Damage: Cracks caused by ongoing movement or moisture problems may return if the underlying issue isn’t fixed before painting.
Drywall Patching vs. Skim Coating: What’s the Difference?
Drywall patching fixes localized damage, whereas skim coating smooths larger areas with widespread surface imperfections. Here’s how the two stack up:
| Drywall Patching | Skim Coating | |
| Purpose | Repairs individual areas of damage | Creates a smoother, more uniform surface |
| Best For | Holes, dents, cracks, and gouges | Uneven texture, shallow imperfections, and poorly blended repairs |
| Application | Joint compound, spackling, or drywall patches applied to damaged spots | Thin layers of joint compound spread over larger sections or entire walls |
| Repair Area | Typically small, isolated sections | Larger portions of a wall or the entire surface |
| Finishing | Sanding and blending the repaired area into the surrounding wall | Smoothing the coated surface before priming and painting |
When Does Drywall Need to Be Patched Before You Paint?
Patching is usually the best approach when the damage is limited to a few spots and the surrounding drywall is still in good condition. The type and size of the damage determine how extensive the repair needs to be.
Common drywall issues you can fix with patching include:
- Nail and screw holes
- Dents and bumps in the surface
- Small cracks
- Anchor and fixture holes
- Localized drywall damage, such as broken or punctured sections that need replacement drywall
Some of these repairs are easy — you may just need to add a little bit of spackling to cover a nail hole. Others require a bit more expertise, like a hole several inches across that may need a drywall patch, joint tape, and several coats of compound.
When Is Skim Coating Necessary Before Painting?
Sometimes, the imperfections are spread across too much of the wall for individual patches to be practical. Skim coating can help create a more even surface, particularly on older walls or drywall that has undergone extensive repairs.
It’s usually a good idea when you’re dealing with:
- Widespread surface imperfections, including shallow dents or scratches
- Poorly blended previous repairs, such as raised edges or patches that are still visible
- Wallpaper removal damage
- Unwanted wall texture
- Multiple patched areas
Skim coating is best for drywall that’s structurally sound. If you’ve got loose drywall paper, damaged seams, or moisture problems, you’ll need to start there. And if only a handful of spots need attention, patching is usually the simpler, less labor-intensive option.
What Happens After Drywall Repairs and Before Painting?
Once the holes are filled and the uneven surfaces are smoothed out, you’ll have a few more things to do before painting to make sure the finished surface looks seamless.
After the drywall compound has dried, the next steps include:
- Sanding and Blending: Sand the repaired areas smooth, feathering the edges into the surrounding wall so you don’t end up with noticeable ridges.
- Removing Dust: Sanding kicks up a good bit of dust, and that can affect paint adhesion, so wipe away the dust before moving on.
- Matching the Existing Texture: If you have textured walls, you’ll need to match the surrounding texture on the repaired areas.
- Priming the Repairs: Primer seals porous joint compound and helps prevent flashing, where repaired areas look duller or shinier than the surrounding painted surface.
Once the surface is clean, dry, and properly primed, it’s time for the exciting part: painting!
Pre-Painting Drywall Repairs: Frequently Asked Questions
If you’re staring at a wall that’s seen better days and still have questions about what, exactly, needs to happen before painting, we’ve got you covered. Here are answers to some of the most common questions we get.
How much does drywall repair cost before painting?
Professional drywall repairs usually cost between $300 and $900, though that can vary quite a bit based on the level of damage you’re dealing with. Skim coating can cost a bit more because it tends to be more labor intensive, with prices sometimes reaching $1,200.
These costs are separate from actual interior painting costs, so ask your painter about what’s included.
Do you need to skim coat an entire wall before painting?
Not usually. If your wall has a few old dents or nail holes, there’s little reason to skim coat the whole thing. Now, if you’re dealing with years of poorly blended patches, uneven texture, or damage left behind by wallpaper removal, a full skim coat might be a good idea.
Can professional painters repair drywall before painting?
Many can, but that’s a good thing to confirm when you’re getting an interior painting estimate. Painters often handle smaller repairs, such as filling nail holes, fixing dents, and patching minor damage.
More extensive work, such as replacing whole sections of drywall, may require a separate repair specialist.
Do drywall patches need to be primed before painting?
Yep, they sure do. Skipping primer can leave you with a frustrating surprise once the paint dries.
Fresh joint compound tends to soak up paint differently than the surrounding wall, which can leave a dull-looking patch even after you’ve painted over it. Priming the repair helps even out that absorption so the finished wall looks consistent.
What happens if you don’t repair drywall before painting?
The damage will still be there. And unfortunately, paint doesn’t magically cover imperfections (though it would definitely be nice if it did). Those little dings, holes, and dips in the wall will still be there and likely quite visible, so it’s best to repair before you paint.
How long does drywall repair take before painting?
It depends on how much damage needs attention. Filling a few nail holes might only take a minute or two of work, but larger patches and skim coating can take a whole lot longer. Joint compound needs time to dry between coats, and humidity can slow things down, so you could be looking at several days.
Can you paint over torn drywall paper?
You technically could, but it’s not a good idea. The exposed paper can absorb moisture from the paint or joint compound, causing it to bubble or wrinkle.
The damaged area typically needs to be trimmed, sealed with an appropriate primer or sealer, and smoothed with joint compound before painting. If you skip those steps, you might end up with a rough, uneven spot that’s tough to hide.
