How to Smooth a Textured Ceiling (Skim Coat Tutorial)

If you’ve been staring at a textured ceiling and wondering if it’s possible to get a smooth finish without ripping out the drywall and starting over, I’m happy to report… yes. It’s absolutely doable. We used the same approach we’ve used on walls in the past: mudding, sanding, repeat. It’s not complicated, but it does take some time, as you have to work in layers, allowing it to dry in between. The good news is that once you get your rhythm down, the process is straightforward and the end result is well worth the effort. In today’s post, I’m walking you through exactly how to smooth a textured ceiling, what tools we used, and what made the biggest difference for getting a clean, level five finish.

If you’re trying to get perfectly smooth walls, hop over and check out my skim coating tutorial. We used the same tools for the ceiling! Let’s dive in…

Why Smooth a Textured Ceiling?

A smooth ceiling is one of those high-end details that makes everything in a room look better. Millwork feels more tailored, paint or wallpaper looks cleaner, and even lighting feels more intentional, with less shadowing. If you’re already renovating a space, now is the time to smooth your ceiling.

The Method We Use to Smooth a Textured Ceiling

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. If you’ve skim coated walls before, this will feel familiar. If you have a highly textured ceiling (think popcorn), you will need to scrape that before skim coating. Our existing texture (pictured above) is what I would call normal or medium. Below, is the finished ceiling.

Tools and Materials

You truly don’t need anything complicated, but having the right skimming blade makes a difference. Here’s exactly what we used:

• Plastic Sheeting or Drop Cloths
• Joint Compound (we like ultraweight)
• Roller with a 3/4″ Nap, pictured above (the nap is important because it provides texture and rolls it on thick)
• Skimming Blade (I have a 32″ for walls and a 12″ & 14″ for working around outlets and windows)
• Pole Sander
• Sanding Pads (I use 220 and 180)
• Drill with Mixer Attachment
• Bucket with a Lid (to keep it from drying out in between passes)
• Primer (PVA primer on fresh drywall / joint compound)
• Ceiling Paint

Step 1: Prep the Room

Before you start, cover everything. This is one of those projects where prep saves your sanity. Because we’re renovating, we moved everything out of the room, then covered the floors with plastic. If you’re working around light fixtures, either remove them or cover them carefully so you’re not fighting them the entire time. Once everything is protected, give the ceiling a quick clean. A light vacuum pass helps knock down dust and cobwebs so your mud goes on smoother.

Step 2: Mix Your Joint Compound

This is one of those small steps that makes the rest of the project so much easier. We like to slightly thin the joint compound with water and mix it until it’s smooth and spreadable. You don’t want it runny. You just want it workable so it glides instead of dragging. Think creamy consistency that holds on your knife, but spreads easily.

Step 3: Apply the First Coat of Mud

For the first coat, you’re not chasing perfection. The goal is coverage. Working in sections, roll a coat of joint compound over the textured ceiling, then smooth it using your large drywall blade. Keep your pressure consistent and aim for an even layer. Don’t worry about a few lines or edges here and there. This coat is simply the first step in flattening out the texture. Let it dry completely before sanding.

Step 4: Sand the First Coat

Once the first coat is fully dry, sand it down to knock off any ridges or high spots. We use a pole sander for ceilings because it keeps the pressure even and it saves your arms. You don’t need to sand it perfectly smooth yet. The goal is just to level it enough so the next coat goes on easily. After sanding, vacuum the ceiling and the room. Dust left behind can create bumps in your next coat.

Step 5: Apply a Second Coat (and Sometimes a Third)

This is where everything starts looking really good. Your second coat is what smooths out the remaining texture and fills any low areas. Again, keep it thin. A heavy coat is harder to sand and more likely to show imperfections. Depending on how heavy your ceiling texture is, you may need a third coat. We’ve had ceilings that looked great after two, and others that needed one more quick pass to look truly smooth. The nursery ceiling (pictured here) took three coats, so be patient. Let each coat dry completely before sanding.

Step 6: Final Sanding and Touch Ups

After your last coat, sand lightly with a finer grit sanding pad. This is when you’re aiming for that smooth, seamless finish. If you notice a small dip or a line you don’t love, do a quick touch up with a thin skim of mud, let it dry, then sand again. This is the part that takes a little patience, but it’s also what makes the final ceiling look intentional and professional.

Step 7: Prime the Ceiling

Before painting, prime the ceiling. Joint compound is porous, and primer gives you a consistent surface so your ceiling paint looks even. It’s a must for getting a clean, level five finish. Once the primer dries, you can spot any final imperfections. This is also why I love priming. It’s a final check before paint.

Step 8: Paint the Ceiling

After primer, it’s time to paint your ceiling. If you’re painting the ceiling white, I always like to use Ceiling Bright White by Sherwin-Williams. Once it’s painted, that smooth finish really comes to life and the whole room instantly looks more pulled together.
