Can you apply texture to painted drywall with a brush?

Let’s dive into the details and find out.

Understanding the Basics of Texturing Drywall

Before we address the possibility of applying texture to painted drywall with a brush, it’s important to understand the fundamentals of creating texturized surfaces on drywall. There are several techniques commonly used to achieve different textures, including:

1. Sand Swirls: This technique involves applying drywall mud to the wall using a brush or roller and then swirling it with a circular motion to create a swirled pattern.
2. Knockdown: In this method, drywall mud is applied to the wall using a trowel or a roller, and once it partially dries, it is smoothed down with a trowel to create a flattened yet textured surface.
3. Skip Trowel: This technique involves applying drywall mud to the wall using a trowel and then lightly skimming it to create a random texture with subtle differences in thickness.
4. Slap Brush: This method requires a texture brush with stiff bristles. The drywall mud is applied to the wall, and then the brush is slapped against it repeatedly to create a texture resembling leaves or petals.
5. Stipple: Using a stiff brush or a stippling brush, this technique creates a fine, repeated pattern by tapping or stippling the brush against the wall.

Preparing the Painted Drywall

If you wish to apply a texture to painted drywall, it’s essential to prepare the surface correctly. Here’s a step-by-step guide to the preparation process:

1. Clean the Surface: Begin by thoroughly cleaning the painted drywall to remove any dust, dirt, or grease.
2. Sand the Surface: Use fine-grit sandpaper to lightly sand the painted surface. This step helps create a rougher texture on the wall, allowing the texture compound to adhere better.
3. Prime the Surface: Apply a coat of primer specifically designed for painting over glossy or previously painted surfaces. This step ensures better adhesion of the texture compound and creates a more uniform surface.

Applying Texture with a Brush

While applying texture to an unpainted drywall is typically easier, it is still possible to achieve textured effects on painted drywall using a brush. Here are the steps to follow:

1. Choose the Right Texture Compound: Select a texture compound suitable for application over painted surfaces. Make sure the product is compatible with your chosen texture technique.
2. Thin the Texture Compound: Most texture compounds need to be thinned down with water to achieve the desired consistency. Follow the manufacturer’s instructions carefully.
3. Apply the Texture Compound: Using a brush, apply the thinned texture compound to the wall in the desired pattern or technique. Work in small sections, ensuring an even and consistent application.
4. Experiment and Practice: Create a few test patches on a small area of the wall to perfect your technique and achieve the desired texture effect.
5. Allow Drying and Cure Time: Once the texture is applied, it is crucial to allow sufficient drying and cure time as indicated by the manufacturer. This ensures the texture adheres properly and prevents any issues when applying subsequent coats of paint.
6. Paint the Textured Surface: After the texture has dried, you can paint the textured surface using your desired color or finish. Be mindful of using appropriate paint products that are compatible with textured surfaces.

It is indeed possible to apply texture to already painted drywall using a brush. By following the correct preparation steps and selecting the appropriate texture compound, you can achieve a visually appealing and unique textured surface. Remember to experiment and practice before tackling larger areas, and always allow sufficient drying and cure time before painting. By incorporating texture into your painted drywall, you can add depth, interest, and personality to any room in your home.
