Textured walls, once a popular design choice for adding depth and character to homes, can now feel outdated or impractical for modern living. Whether you’re aiming for a sleek, minimalist look, preparing walls for wallpaper, or simply tired of the uneven surface collecting dust, smoothing out textured walls is a achievable DIY project with the right tools and techniques. In this guide, we’ll walk you through the entire process, from assessing your wall’s texture to applying the final coat of paint, ensuring professional results without hiring a contractor.

First, it’s essential to understand the type of texture on your walls, as different textures require slightly different approaches. Common types include orange peel (subtle, bumpy texture), knockdown (heavier, irregular patterns), and popcorn (fluffy, popcorn-like texture, often found on ceilings). Popcorn texture may contain asbestos in older homes, so always test for asbestos before starting—if present, hire a professional. For non-asbestos textures, proceed with confidence.

Next, gather your tools. You’ll need: a putty knife or drywall knife (4-inch and 12-inch), sandpaper (80-grit and 120-grit), sanding block or pole sander, joint compound (all-purpose or lightweight), a mixing bucket, water, a paint roller and tray, painter’s tape, drop cloths, safety gear (dust mask, goggles, gloves), and a sponge or damp cloth. Having these tools ready will streamline the process and prevent delays.

Preparation is key to avoiding mess and ensuring adhesion. Start by clearing the room or covering furniture with drop cloths. Remove wall plates, nails, or hooks, and tape off trim, windows, and doors with painter’s tape. Use a damp sponge to wipe down the walls, removing dust, dirt, or grease—this helps the joint compound stick better. For popcorn texture, gently scrape off the top layer with a putty knife first; be careful not to damage the underlying drywall. For orange peel or knockdown textures, skip scraping and move straight to smoothing.

Now, it’s time to apply the joint compound, also called “skim coating.” Skim coating is the most effective method for smoothing textured walls, as it creates a thin, even layer over the texture. Start by mixing the joint compound: add a small amount of water to the bucket, then gradually stir in the compound until it reaches a thick, creamy consistency (similar to pancake batter). Test it by spreading a small amount on the wall—if it’s too thick, it will crack; too thin, it will run.

Using the 4-inch drywall knife, apply a thin first coat of compound to a small section of the wall (about 3x3 feet) to avoid the compound drying too quickly. Hold the knife at a 45-degree angle and spread the compound evenly, working in smooth, overlapping strokes. Focus on filling in the texture’s peaks and valleys. Let this first coat dry completely—this usually takes 24 hours, but check the product instructions.

Once dry, sand the wall lightly with 80-grit sandpaper to smooth any rough spots or ridges. Use a sanding block for smaller areas or a pole sander for larger walls to reduce arm strain. Wipe away dust with a damp cloth to prepare for the second coat. The second coat should be even thinner than the first, applied with the 12-inch knife to create a seamless finish. Again, let it dry fully, then sand with 120-grit sandpaper for a ultra-smooth surface.

For stubborn textures or deeper grooves, you may need a third coat. Repeat the process: apply thin compound, dry, sand, and dust. The goal is to build up layers gradually rather than trying to cover the texture in one thick coat, which can lead to cracking or peeling.

After the final sanding, your walls should feel smooth and even. Now it’s time to prime and paint. Apply a high-quality drywall primer to seal the compound and ensure uniform paint adhesion. Let the primer dry, then follow with two coats of your chosen paint (latex or enamel work best for walls). Use a roller with a short nap (3/8-inch) for a smooth finish, and avoid overloading the roller to prevent drips.

Stand back and admire your handiwork! What was once a bumpy, outdated textured wall is now a sleek, modern surface ready to complement any decor. With patience and the right techniques, smoothing out textured walls is a DIY project that saves money and gives you full control over the final result.

Remember, practice makes perfect. If you’re new to skim coating, test the process on a small, inconspicuous area first to get a feel for the compound’s consistency and the knife’s angle. Don’t rush the drying or sanding steps—taking your time ensures a professional, long-lasting finish. Whether you’re refreshing a single room or your entire home, smoothing out textured walls is a rewarding project that transforms your space from dated to dazzling.
