Best Paint for Exterior Brick: Top Choices & Tips

When it comes to protecting and enhancing the appearance of your exterior brick, choosing the right paint is crucial. The best paint for exterior brick not only provides a fresh look but also shields the brick from weathering, moisture, and other damaging elements. However, with numerous options available, selecting the right one can be overwhelming.

This guide will walk you through the key aspects to consider when choosing the best paint for your exterior brick, ensuring a durable, long-lasting, and attractive finish.

Understanding Exterior Brick Paint

Exterior brick paint is specifically designed to adhere to the porous surface of bricks, providing a protective barrier while allowing the brick to breathe. It's essential to choose a paint that is breathable, as non-breathable paints can trap moisture, leading to mold growth and damage to the brick.

Brick paints are typically available in two types: lime-based and acrylic. Lime-based paints are more traditional and offer excellent breathability, but they may not be as durable or easy to apply as acrylic paints. Acrylic paints, on the other hand, provide better durability and easier application, but they may not breathe as well as lime-based paints.

Lime-Based Brick Paints

Lime-based brick paints are formulated with natural hydraulic lime, which allows the brick to breathe while providing a protective layer. They are ideal for historic or heritage buildings, as they help maintain the brick's natural appearance and texture. Lime-based paints are typically more expensive and require more skill to apply, but they offer excellent longevity and weather resistance.

Some popular lime-based brick paints include those by Limeworks, Keim, and Olde English. When using lime-based paints, it's crucial to prepare the surface correctly and apply the paint in optimal weather conditions to ensure a successful outcome.

Acrylic Brick Paints

Acrylic brick paints are water-based and offer superior durability, ease of application, and a wide range of colors. They are an excellent choice for modern buildings and can be applied using a brush, roller, or sprayer. Acrylic paints are generally more affordable than lime-based paints and can be touch-dried within hours, allowing for faster completion of the project.

Some well-regarded acrylic brick paints include those by Dulux, Johnstone's, and Sandtex. When using acrylic paints, ensure the surface is clean, dry, and free of any contaminants to achieve the best results.

Preparing the Surface for Painting

Preparing the surface is crucial for ensuring the paint adheres properly and provides a durable, long-lasting finish. Begin by cleaning the brick surface using a suitable cleaner or a solution of water and detergent. Remove any mold, mildew, or algae using a fungicidal wash, and allow the surface to dry completely.

Inspect the brick for any damage, such as cracks or loose mortar, and repair these areas before painting. Additionally, ensure the brick is free of any efflorescence – a white, powdery substance that can occur when moisture evaporates from the brick. Efflorescence can prevent paint from adhering properly, so it's essential to remove it using a suitable cleaner.

Priming the Surface

Priming the surface is an essential step in preparing the brick for painting. A primer creates a uniform surface, improves paint adhesion, and helps the paint last longer. Choose a primer specifically designed for exterior brick, such as those by Zinsser or Dulux. Apply the primer using a brush or roller, following the manufacturer's instructions for application and drying times.

Priming the surface also helps to identify any areas where moisture may be present, as the primer will darken in these areas. This allows you to address any moisture issues before painting, ensuring a successful outcome.

Choosing the Right Paint Finish

Exterior brick paints are available in various finishes, ranging from flat and satin to semi-gloss and gloss. The finish you choose will depend on the desired appearance and the level of maintenance required. Flat finishes are more forgiving of minor imperfections and provide a more natural, matte look. However, they may be more challenging to clean and maintain than glossier finishes.

Satin and semi-gloss finishes offer a balance between appearance and durability, providing a subtle sheen while still allowing the brick's texture to show through. Gloss finishes are the most durable and easiest to clean but may make the brick appear less natural and more artificial.

Ultimately, the best paint for exterior brick is one that offers excellent breathability, durability, and adhesion, while also providing the desired appearance and finish. By understanding the different types of brick paints available and following proper surface preparation and application techniques, you can achieve a stunning, long-lasting result that enhances the beauty of your exterior brick.
