Picture this: you pick the perfect paint color, roll on the first coat, and every bump in the wall throws its own tiny shadow. That’s usually the moment people start searching for how to remove texture from walls.
Quick answer: The most dependable fix is a skim coat. You spread a few thin layers of drywall mud over the whole wall, sand lightly between layers, and let each one dry fully until the bumps disappear. A coat of primer seals everything before paint. Scraping can work on bare, unpainted texture, but it’s riskier because it can tear the drywall surface.
At San Diego Home Remodeling, we put this guide together so you can pick the right approach for your wall before you buy a single tool.
Key Takeaways
- Skim coating is the most reliable method for most walls, especially painted ones.
- Scraping only suits bare, unpainted texture.
- Test older homes for asbestos and lead before any sanding or scraping.
- Knock down sharp peaks first so your knife doesn’t snag.
- Thin coats, full dry time, then primer.
Why People Want to Remove Wall Texture
Texture started as a shortcut. It hid taping marks and sped up finishing. Today it works against you. Dust lodges in every bump, touch-up paint never blends in, and glossy paint exposes every ridge.
Wall texture removal also pays off if you plan to hang wallpaper, try a bolder color, or build an accent wall. Smooth walls show color evenly and make a room feel brighter. Sellers like them too, since flat walls look cleaner in listing photos.
Check for Asbestos and Lead Before You Start
Older homes need a safety check first. Spray-on texture and acoustic finishes in homes built before 1980 can contain asbestos, and homes built before 1978 may have lead paint under the texture. Sanding or scraping either one releases hazardous dust.
Send a small sample to a certified lab and wait for the results. For lead, the EPA’s lead guidance explains testing and safe renovation practices. If a test comes back positive, stop and call a licensed abatement professional, who can tell you whether to remove the material or seal it in. Don’t cover it up and hope for the best.
Identify Your Texture Type
The finish on your wall changes how much work you’re signing up for.
- Orange peel: a fine, bumpy spray finish. The easiest to flatten.
- Knockdown: spray texture pressed flat with a knife, leaving low plateaus. Moderate.
- Skip trowel: thick, hand-troweled patches. Plan on extra coats.
- Sand texture: grit mixed into the paint. Scraping won’t work, so it needs a skim coat.
- Popcorn or acoustic: lumpy and common on ceilings, but it turns up on walls too.
Depth matters as much as type. A shallow orange peel might need two thin coats, while a heavy skip trowel can need four.
Do the 3-Minute Wall Test
For scraping: a pump sprayer, a 6- to 10-inch drywall knife, drop cloths, painter’s tape, a dust mask, safety glasses, a sanding sponge, and PVA primer.
For skim coating: all-purpose joint compound, a 5-gallon bucket, a mixing paddle and drill, a thick-nap roller, 10- and 12-inch taping knives, a pole sander with 80-grit paper, fine sanding screens, a work light and PVA primer.
Which Method Is Best?
If you want one approach that works on almost any wall, choose skim coating. It’s the safest answer to how to remove texture from walls when you can’t be sure what’s under the paint.
Wall condition | Best method | Difficulty |
Unpainted light texture | Soak and scrape | Easy |
Painted orange peel | Skim coat | Moderate |
Painted knockdown | Knock down peaks, then skim coat | Moderate |
Skip trowel or heavy texture | Several skim coats | Hard |
Sand texture | Skim coat | Moderate |
Damaged drywall or asbestos | Cover it or call a pro | Varies |
Method 1: Soak and Scrape Unpainted Texture
Water softens bare texture faster than it harms the drywall, as long as you stay organized.
- Prep the room. Shut off power to the room’s outlets, since you’ll be spraying water. Lay drop cloths, tape the trim, and remove outlet covers.
- Soak a small section. Work in patches about 4 by 4 feet. Spray warm water and wait a couple of minutes until the surface darkens.
- Scrape at a shallow angle. Hold the knife nearly flat, around 15 to 30 degrees, and push in long, steady strokes.
- Respray as needed. If a patch dries before you reach it, wet it again. Scraping dry texture tears the paper face.
- Dry, sand, and prime. Give the wall a full day to dry, sand the rough spots lightly and apply PVA primer.
Even a clean scrape often leaves small scars. Many people follow it with one light skim coat for truly smooth walls.
Method 2: Skim Coat Over Painted Texture
A skim coat simply builds a new flat surface on top of the old one. Water can’t soften painted texture, so building over it beats fighting it.
- Prep the room. Remove baseboards, outlet covers, and switch plates. Tape off electrical boxes, lay down drop cloths, and hang plastic over doorways. Sand glossy paint lightly.
- Knock down the high points. Use a wide knife or a pole sander with 80-grit paper to shave sharp peaks and paint splatters. Your tools won’t catch, and the first coat goes on far more evenly. Vacuum the dust.
- Mix the mud. Thin the joint compound with a little water until it’s as smooth as yogurt, with no lumps.
- Roll on a thin coat. Cover a 4-by-4-foot section using a thick-nap roller.
- Flatten it. Pull a wide knife across in long strokes, moving from dry areas into the wet edge so you don’t leave lines. The first coat will look rough. That’s normal.
- Dry and smooth. Wait about 24 hours, longer in humid weather. Sand ridges with fine paper, around 220-grit, or wipe gently with a damp sponge. Vacuum again.
- Add a second coat. Apply a thinner layer in the opposite direction to fill low spots. Deep textures may need a third.
- Finish. Do one last light sanding before primer.
Two edge cases trip people up. Inside corners collect extra mud, so run a clean knife down them while the coat is wet. Where the wall meets an untextured surface, feather the edge outward so you don’t leave a visible ledge.
Method 3: Cover the Texture
Sometimes covering beats removing. If the texture is extremely heavy, the drywall is damaged, or a pro advises sealing in a hazard, you can hang new quarter-inch drywall over the old wall or install paneling or shiplap. Peel-and-stick wallpaper is tempting, but it usually shows the bumps through. The trade-off is a thicker wall, so outlets and trim need adjusting.
What If the Drywall Paper Tears?
It happens to almost everyone. Torn paper bubbles under joint compound and ruins the finish. Let the area dry, sand the ragged edges, and seal the bare paper with primer before applying any mud. After that, a skim coat will hide the damage.
Can You Just Paint Over Textured Walls?
You can, and for light texture in a rental it’s a fine quick fix. Paint won’t remove shadows or raised patterns, though. If smooth walls are the goal, you need real wall texture removal, not another coat.
Common Mistakes to Avoid
- Skipping the asbestos and lead test in an older home.
- Soaking the wall until the drywall paper swells.
- Scraping painted texture, which gouges the wall.
- Applying thick coats that crack as they dry.
- Sanding too early, before the mud is fully dry.
- Painting without primer, which leaves blotchy patches.
How Long Does It Take and What Does It Cost?
Scraping a bedroom takes about a day plus drying time. A skim coat usually runs two to three days because each coat needs to cure. DIY materials commonly cost $50 to $150 per room if you already own basic tools.
Hiring out varies by region and wall condition, but published estimates for skim coating labor often land around $1 to $2 per square foot. Picture a 12 by 12 bedroom with about 380 square feet of wall. That works out to roughly $380 to $760, and deep texture or drywall repairs push it higher. Treat these as ballpark figures and get a local quote.
San Diego Conditions That Change the Job
Local weather matters more than people expect. Coastal humidity and the morning marine layer can stretch drying times, so give each coat its full 24 hours. On hot, dry Santa Ana days, mud can dry too fast and crack, so keep fans from blowing straight at wet walls. Many local homes date from the 1950s to the 1970s, which makes that safety test a smart first step.
Prime and Paint the Right Way
Once the last coat is dry and lightly sanded, apply a PVA drywall primer. Fresh joint compound is porous and drinks paint unevenly, which causes blotches. Let the primer dry, then check the wall under low light before you open the paint.
Sheen matters too. Flat or matte paint hides small flaws, while satin and semi-gloss highlight them.
When Should You Call a Pro?
DIY suits one or two rooms with light texture. Call a pro if your home predates 1980, the drywall has water damage, the space is a large open area, or the finish has to be flawless for a sale.

Final Thoughts
It comes down to one question: is the texture painted? Unpainted texture can be soaked and scraped, painted texture gets a skim coat, and damaged or hazardous walls get covered or handled by a specialist. Test first, work in small sections, be patient between coats, and always prime. If you’d rather hand the job off, contact us and San Diego Home Remodeling will walk you through your options.
FAQs About Getting Rid of Textured Walls
Can I remove texture from walls without damaging the drywall?
Yes. Keep your scraper at a low angle, work in small sections, and avoid oversaturating the wall. For painted texture, skim coating is safer because it builds over the surface rather than stripping it.
How do I know if my texture has been painted?
Run a finger across the surface. The painted texture feels smooth and slightly slick on the raised bumps. The unpainted texture has a chalky, matte feel and absorbs water quickly when sprayed.
How many coats of skim coat do I need?
Most walls need two to three coats. Heavy textures like skip trowels may need four. Keep each coat thin, thick single coats crack as they dry.
What primer do I use after skim coating?
PVA drywall primer. It seals the porous surface of joint compound so paint applies evenly. All-in-one paint-and-primer products are not a replacement for PVA on fresh compounds.
Is removing wall texture worth it before selling?
In most markets, yes. Smooth walls photograph better, signal a well-maintained home, and appeal to a wider range of buyers. The cost is usually recovered in buyer perception and sale price.
Can I skim the coat over the painted texture without removing the paint first?
Yes. Lightly sand the painted surface to improve adhesion, then apply your first coat of joint compound directly over it.
