If you’re looking to give your walls a unique texture, knockdown texture is a great option.
This texture style is achieved by applying joint compound to the walls and then flattening it with a knockdown knife. While this technique is traditionally done with a spray gun, it is possible to achieve knockdown texture with a roller.
To get started, you’ll need a few tools and supplies, including a 12″ drywall knife, drywall mud pan, and a knockdown knife.
You’ll also need a paint roller and a texture roller cover. Before you begin, make sure to prep your walls by cleaning them and filling in any holes or cracks.
To apply the knockdown texture with a roller, start by applying the joint compound to the wall with the paint roller.
Use the texture roller cover to create the desired texture on the wall.
Once the joint compound has dried, use the knockdown knife to flatten the peaks and create the knockdown effect.
With a bit of practice, you can achieve a professional-looking knockdown texture with just a roller.
Understanding Knockdown Texture

As a professional painter, I’ve worked with a variety of textures over the years, and one of my favorites is the knockdown texture.
It’s a versatile texture that can be used on walls and ceilings, and it adds a unique visual interest to any room.
In this section, I’ll explain what knockdown texture is and how to achieve it with a roller.
Knockdown texture is a type of drywall texture that creates a flattened, marbled appearance. It’s achieved by applying joint compound to the wall or ceiling and then knocking it down with a trowel or knockdown knife.
The result is a texture that has a subtle, mottled look that is easy to paint over.
There are different types of knockdown texture, including splatter knockdown and stomp knockdown.
Splatter knockdown is achieved by spraying the joint compound onto the wall, while stomp knockdown is created by stomping the compound with a brush or roller.
However, in this article, I’ll focus on how to achieve knockdown texture with a roller.
One of the benefits of using a roller to create knockdown texture is that it’s easy to do and doesn’t require any special tools.
All you need is a paint roller, joint compound, and a knockdown knife. You can also use a drywall knife if you don’t have a knockdown knife.
Materials and Tools Required
Choosing the Right Roller
When it comes to doing knockdown texture with a roller, choosing the right roller is crucial.
You should use a textured roller that is specifically designed for this purpose. These rollers come in various sizes and textures, so it’s important to choose one that suits your needs.
A roller with a heavy nap will create a more pronounced texture, while a lighter nap will produce a subtler effect.
Other Essential Tools
In addition to a textured roller, you will need a few other tools to complete the job. Here are the essential tools you will need:
- Drywall mud pan
- Drywall knife
- Joint compound
- Sandpaper
- Spray bottle
- Paintbrush
- Paint roller
The drywall mud pan is used to hold the joint compound, which is applied to the wall using the drywall knife.
Sandpaper is used to smooth out any rough spots or imperfections in the texture.
A spray bottle is used to dampen the wall before applying the joint compound, which helps the compound adhere better.
A paintbrush is used to cut in around the edges of the wall, while a paint roller is used to apply the joint compound to the larger areas.
Preparing the Wall Surface
Before applying knockdown texture with a roller, it is essential to prepare the wall surface properly. Here are the steps I take to ensure a smooth and even texture:
-
Clean the Wall: First, I clean the wall surface thoroughly to remove any dirt, dust, or debris. I use a soft-bristled brush or a vacuum cleaner to clean the surface. This step ensures that the texture adheres to the wall surface properly.
-
Repair Any Damage: Next, I repair any damage to the wall surface, such as cracks, holes, or dents. I use spackle or joint compound to fill in the damaged areas. After filling in the damaged areas, I let the compound dry completely.
-
Sand the Wall: Once the compound is dry, I sand the wall surface with a fine-grit sandpaper to ensure that the surface is smooth and even. Sanding also helps the texture adhere to the wall.
-
Apply a Primer: Before applying the texture, I apply a primer to the wall surface. The primer helps the texture adhere to the wall and also ensures that the texture dries evenly.

Mixing the Texture Compound
Before applying the knockdown texture, it is important to mix the texture compound properly.
I recommend using a pre-mixed texture compound to save time and ensure consistency. However, if you prefer to mix your own, you can use a drywall joint compound mixed with water to achieve the desired consistency.
To mix the texture compound, start by pouring the pre-mixed texture compound or drywall joint compound into a large bucket.
Add water gradually, stirring constantly until the mixture becomes smooth and creamy. The texture compound should be thick enough to hold its shape on the roller but thin enough to spread easily.
Roller Techniques
When applying the knockdown texture with a roller, it is important to use the right technique to achieve the desired texture. Here are a few tips to help you get started:
- Use a thick-nap roller cover to create a deeper texture. A 3/4-inch or 1-inch nap roller cover is ideal for knockdown texture.
- Load the roller cover with texture compound, but don’t overload it. Too much compound can cause the texture to become too thick and difficult to spread.
- Roll the texture onto the wall in a random pattern, using light pressure. Avoid rolling over the same area twice, as this can flatten the texture.
- After rolling the texture onto the wall, wait a few minutes for it to set up. Then, use a drywall knife or trowel to “knock down” the peaks of the texture, creating a mottled, flattened look.
- For a more pronounced texture, wait longer before knocking down the peaks. For a subtler texture, knock down the peaks sooner.

Knocking Down the Texture
Once the knockdown texture has been applied to the wall, it’s time to “knock it down.” This means smoothing out the peaks and creating a more uniform texture.
To do this, I use a knockdown knife, which is a wide, flat tool with a curved edge.
To use the knockdown knife, I hold it at a slight angle and lightly drag it across the surface of the texture. This removes the peaks and creates a more uniform texture.
It’s important not to press too hard, as this can remove too much texture and leave the wall looking flat.
Painting Over the Texture
Once the knockdown texture has been applied and knocked down, it’s time to paint. I recommend using a roller with a medium nap, as this will help to fill in any gaps in the texture and create a more uniform finish.
Before painting, I always prime the wall to ensure that the paint adheres properly and to prevent any stains or discoloration from bleeding through.
Once the primer has dried, I apply the paint in thin, even coats, being careful not to overload the roller.
It’s important to let each coat dry completely before applying the next. This usually takes about 2-4 hours, depending on the type of paint and the humidity in the room.
Once the final coat has been applied, I let it dry for at least 24 hours before hanging any pictures or decorations on the wall.
