To smooth out rough walls, no single paint can magically fill deep imperfections; painting over them usually highlights flaws. You must first physically smooth the surface using joint compound (skim coating). Once prepped, use high-build primer combined with satin, eggshell, or matte finish acrylic latex paint applied with a very short-nap roller.
Polycell Polyfilla SmoothOver for Damaged & Textured Walls is the easy way to create a perfect foundation for a great finish. Its special self-levelling formula fills between ridges and bumps and covers cracks and large areas of damage giving a smooth finish that's ready to paint.
Sand it down heavily and then skim coat with drywall mud, when that dries lightly sand the mudded spots. Repeat until it hits the texture you want. Prime it and paint it - if you roll the paint on, it will actually add a bit of texture back to the wall from the nap of the roller.
Perfectly Smooth Walls: A Skim Coating Tutorial
To hide uneven walls and surface imperfections, choose a premium matte (or dead flat) finish. Sheens reflect light, which emphasizes bumps, dents, and texture. Pair this with lighter, neutral colors to soften harsh shadows.
If you have textured wall surfaces or wallpaper, you might hesitate about painting over them. However, while it can take a little more time and requires a little more effort compared to smooth walls, painting textured walls really isn't as difficult as you might imagine.
To smooth out rough, dried paint, sand the surface with a fine-grit abrasive to flatten the texture, wipe away the dust, and apply a fresh, thin coat of paint. The exact steps differ slightly depending on whether you are working on a house wall, a piece of furniture, or a car.
A smoothing primer, typically known as a high-build or PVA (polyvinyl acetate) primer, is specifically formulated to equalize surface porosity, fill microscopic pinholes, and hide minor imperfections. It creates an ultra-even base that prevents drywall seams or texture from showing through your final paint coat.
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.
To cover bumpy or textured walls quickly, opt for thick, textured, or non-woven wallpaper, which easily masks irregularities. For a seamlessly smooth finish, apply a "skim coat" of joint compound using a paint roller and a wide taping knife, then sand. Alternatively, attach decorative wooden slat wall panels.
To smooth textured walls without sanding, the best approach is skim coating using a paint roller and a wide drywall skimming blade. This method fills in the textured gaps and flattens the surface using wet-on-wet leveling, eliminating the need for dusty, labor-intensive sanding.
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.
The number of skim coat layers needed depends on the wall's condition and the desired level of smoothness. Typically, two coats are sufficient for most walls. However, if the wall has significant imperfections or you're striving for an ultra-smooth finish, additional coats may be necessary.
Keep a wet edge: Don't let one section dry before rolling the next. Roll in full, even strokes: Start at the top and roll down in overlapping “W” or “M” motions. Maintain consistent pressure: Avoid pressing too hard. Back-roll lightly: After applying paint, make a light pass over the area without reloading your roller.
Paint designed for uneven surfaces may be sold under a range of names including elastomeric paint, high-build paint, crack-free paint or renovation paint (which is basically a filler and undercoat in one). These paints are much thicker than ordinary paints which gives them much better coverage.
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.
To hide wall imperfections, choose a flat or matte finish in a light to mid-tone neutral color. These paints absorb rather than reflect light, masking dents, nail pops, and texture flaws. Top recommendations include Behr Ultra Flat Interior Paint & Primer or premium Benjamin Moore Aura Matte Finish.
Smoothing textured walls is best achieved by skim coating—applying layers of joint compound to fill in the texture. It requires basic supplies (joint compound, a paint roller, a wide drywall knife, and sandpaper), several thin coats, and patience to allow for drying time between layers.
Multiple coats of paint hide color variations, sheen inconsistencies, and faint brush marks, but they will not hide physical surface imperfections like dents, nail holes, or cracks. For a flawless finish, you must repair and sand damage before painting.
To cover up bad drywall work quickly, apply a skim coat of joint compound to smooth out the surface, use a textured paint to hide minor imperfections, or add wallpaper, wood paneling, or strategic wall decor.
For textured walls, it isn't about buying a special "textured paint," but rather choosing the right paint finish (like an eggshell or satin) and a thick-nap roller cover (like 34) inch to easily reach into the indents. This pairing ensures flawless coverage while keeping the texture's character intact.
10 Common Mistakes on Room-Painting Projects
To achieve perfectly smooth walls, "smoothing paint" is not a direct substitute for wall preparation. Paint highlights flaws rather than hiding them. The best approach is to fix the underlying surface by sanding and skim-coating with joint compound before applying a flat or matte paint to minimize light reflection.
If you're repainting walls in similar shades and the surface is clean, smooth and already in good condition, primer may not be necessary (especially when using self-priming paint). However, for major color changes, repairs, stains or challenging surfaces, primer is highly recommended for the best finish and durability.
“Depending on the formula, a primer can smooth out your skin, blur imperfections, control shine, or give you a nice glow,” Machhausen says.
