Removing knockdown texture is best done by skim coating (applying joint compound over the texture to create a flat surface). Scraping and sanding can heavily gouge your drywall, so covering it up is the most effective method.
Yes, you can remove knockdown texture, and the best way to do it is by skim coating rather than scraping or sanding the texture directly off the wall. Because knockdown is usually made of joint compound, trying to sand or scrape it down dry creates an incredible amount of dust and can easily damage the drywall paper underneath.
Fixing knockdown wall texture involves repairing the damaged area with joint compound, applying a matching texture using a spray or sponge, allowing it to set for 10–15 minutes, and then lightly flattening the peaks with a 12-inch knockdown knife. For small repairs, use a sponge to dab on mud, wait, and then gently "knock down" the texture to match the surrounding area.
There are a few ways people go about this, but the method that made the most sense for us was skim coating with joint compound. Instead of trying to scrape the texture off, you're creating a smooth surface over it using thin coats of mud, sanding between coats, and repeating until the ceiling is level and smooth.
Smoothing knockdown textured walls requires skim coating—the process of applying a thin layer of drywall joint compound to fill in the texture. This is typically a 2- to 3-coat process involving rolling or troweling on joint compound, flattening it out with a drywall knife, and sanding until smooth.
Sanding Specific Texture Types
How to sand knockdown texture walls: Because of the raised texture, start with a coarser grit and focus on flattening the peaks.
Yes, you can absolutely paint over textured walls. In fact, it is the quickest and most cost-effective way to update them. Success comes down to using the right, thick-nap roller to reach into the grooves and opting for a matte, eggshell, or satin finish to avoid highlighting the texture.
Remove the Popcorn Ceiling
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
To cover textured walls, you can skim coat the surface with joint compound for a smooth finish, apply heavy-duty wall liners to bridge the texture, or disguise the imperfections using flat paint and smart lighting. Skim coating is the most permanent and traditional method.
Financial Return: The popcorn ceiling removal ROI is often high, as a modernized look can prevent buyers from negotiating the listing price down. Aesthetic Appeal: Choosing a smooth ceiling vs popcorn ceiling instantly brightens a room, making spaces feel significantly larger and cleaner.
Are textured walls out of date? Yes, textured walls are becoming outdated. Builders and consumers are moving away from them because they absorb light, make spaces feel smaller, and create challenges for cleaning and repairs. Smooth walls are now the preferred choice for a modern, sleek, and brighter look.
The best way to remove wall texture without sanding is to use a skim coat. This involves applying a thin, flat layer of joint compound directly over the existing texture to create a smooth surface.
Yes, textured walls can decrease a home's resale value, particularly in regions where smooth walls are standard, as they are often viewed as dated or difficult to repair. While common in some areas (e.g., the Southwest), heavy textures like popcorn or knock-down can reduce value by $500–$1,000 per 500 square feet due to removal costs.
We are 5 - 6 a sqft to scrape, skim coat, prime and paint. It's much more work to go flat on a ceiling than knockdown texture. You could end up painting walls as well.
Yes, textured walls can be smoothed out. The most common and effective method is skim coating. This process involves applying a thin layer of watered-down joint compound over the wall with a drywall knife, letting it dry, sanding it down, and repeating until it is perfectly flat.
The cheapest way to replace or update a ceiling is to cover the existing damaged ceiling rather than tearing it down. You can cover it using paint, adhesive styrofoam ceiling tiles, or by installing a Trusscore Wall & Ceiling Board system, saving thousands in demolition and disposal costs.
In most cases, skim coating your wall makes it easier for a painting job to be perfect. It's more like you are prepping your wall before repainting them. This helps remove uneven surfaces and bumps surfaces. If you paint without skim coating your wall, you might have uneven walls and surfaces.
Yes, you can absolutely paint a textured ceiling. Because textured (or "popcorn") ceilings are highly porous and soak up a lot of paint, the trick is to use a thick nap roller (at least 3/4 inch) or a split-foam roller and apply the paint gently without pressing too hard, which can dislodge the texture.
Covering a textured ceiling is a great way to update your space without the massive mess of scraping. The most popular methods include skim coating for a smooth finish, installing a new layer of drywall over the texture, or installing decorative planks or ceiling tiles.
Yes, you can sand textured ceilings, but whether you should sand them completely smooth depends on if they have ever been painted. For unpainted mud textures, you can sand them down, but for painted textures or popcorn, it is usually much easier to wet and scrape them first or apply a new "skim coat" of drywall mud directly over the texture.
The easiest and most effective way to remove texture from painted walls is to skim coat them. Scraping or sanding is incredibly messy and can easily gouge the drywall, but rolling a thin layer of drywall mud directly over the texture smooths the wall out with far less physical effort.
Red is universally considered the hardest paint color to cover. Vibrant red pigments are highly transparent and inherently prone to bleeding through subsequent layers. Other notoriously difficult colors to cover include black, dark blue, dark green, and bright yellow.
In some cases, you can skim coat over a textured ceiling to make it smooth. Depending on the type of popcorn or texture you have though, it's not always possible. Usually, you can install new 1/4″ thick drywall on top of the existing textured drywall, if you don't want to remove the texture.
