Many homeowners and DIY enthusiasts are drawn to painting brick because it can modernize or personalize a space without the need for costly renovations. However, brick’s porous and textured surface presents specific challenges that call for careful attention. From selecting the appropriate type of paint to prepping the surface, each step plays a crucial role in the success of the project.

Whether you’re aiming to brighten up a dull fireplace or give your home’s exterior a bold new look, knowing how to paint brick properly is essential. In the following sections, we’ll explore the fundamentals of this process, helping you gain the confidence to tackle your brick painting project with ease and achieve beautiful, enduring results.

Preparing the Brick Surface

Before applying any paint, thorough preparation of the brick surface is crucial to ensure proper adhesion and a long-lasting finish. Begin by inspecting the brick for any damage such as cracks or loose mortar, which should be repaired with appropriate masonry filler or repointing. Next, clean the brick surface meticulously to remove dirt, dust, efflorescence, and any previous paint residues. This can be done using a wire brush, stiff broom, or power washer, depending on the level of grime.

Allow the brick to dry completely after cleaning, as moisture trapped beneath paint can cause bubbling or peeling. If the brick is particularly porous or powdery, applying a masonry primer designed to seal porous surfaces is advisable. This primer not only improves paint adhesion but also helps prevent moisture penetration, which can degrade paint over time.

Key steps in preparing brick include:

  • Repairing cracks and damaged mortar
  • Cleaning the surface thoroughly
  • Allowing adequate drying time
  • Applying a masonry primer or sealer if needed

Choosing the Right Paint and Tools

Selecting the appropriate type of paint is essential when painting brick. Exterior masonry paint or elastomeric paint is recommended for outdoor brick because these paints offer flexibility and durability, accommodating the natural expansion and contraction of brick surfaces. For interior brick, acrylic latex paint is commonly used due to its ease of application and clean finish.

In addition to the paint type, the correct tools will facilitate an even and efficient application:

  • Brushes: Use a stiff-bristled brush or masonry brush for detailed areas and mortar joints.
  • Rollers: A roller with a thick nap (¾ inch or more) helps cover larger flat areas effectively.
  • Sprayers: Airless paint sprayers can provide fast, even coverage on large surfaces but may require touch-up with brushes for mortar joints.

The following table summarizes recommended paint types and tools for different brick painting scenarios:

Scenario Recommended Paint Recommended Tools
Exterior Brick Elastomeric or Masonry Paint Stiff Brush, Thick Nap Roller, Airless Sprayer
Interior Brick Acrylic Latex Paint Brush, Medium Nap Roller
Previously Painted Brick Paint Compatible with Existing Finish Brush, Roller, Sanding Tools for Prep

Applying Paint to Brick

Begin painting by cutting in around edges, corners, and mortar lines with a brush to ensure coverage in all crevices. Afterward, use a roller to cover larger flat areas. Apply paint in thin, even coats, allowing each layer to dry fully before applying the next. Brick’s porous surface often requires two or more coats to achieve uniform color and coverage.

When painting mortar joints, maintain a steady hand and use a brush designed for masonry to avoid drips and runs. Be mindful of weather conditions for exterior projects; avoid painting in direct sunlight or when rain is expected within 24 hours, as this can compromise drying and adhesion.

To maintain breathability and prevent moisture buildup, avoid applying overly thick layers of paint. If using a sprayer, back-brush the surface immediately after spraying to work paint into the texture and prevent pooling.

Maintaining Painted Brick Surfaces

Proper maintenance extends the life of painted brick surfaces. Regularly inspect the painted area for signs of peeling, cracking, or mildew. Clean the surface gently with mild detergent and water to remove dirt and prevent mold growth.

If touch-ups are needed, clean the affected area, sand lightly if necessary, and apply paint only to the damaged spots. Avoid repainting the entire surface too frequently, as excessive layers can trap moisture and cause damage.

For exterior brick, periodic resealing with a breathable masonry sealer can help protect the paint and underlying brick from moisture intrusion. Always follow manufacturer recommendations for maintenance products to avoid adverse effects on the painted finish.

Preparing the Brick Surface for Painting

Proper preparation is essential for a durable and attractive painted brick surface. Begin by thoroughly cleaning the brick to remove dirt, dust, and any loose particles that could prevent paint adhesion.

  • Cleaning: Use a stiff-bristle brush and a mixture of water and mild detergent to scrub the brick surface. For tougher stains, a trisodium phosphate (TSP) solution can be applied carefully. Rinse thoroughly with clean water and allow the brick to dry completely.
  • Removing Efflorescence: White powdery deposits known as efflorescence should be removed using a solution of equal parts white vinegar and water. Apply with a brush, scrub gently, and rinse well.
  • Repairing Damage: Inspect for cracks or missing mortar. Use a masonry repair compound or tuckpoint mortar to fill gaps and smooth the surface. Let repairs cure fully according to manufacturer instructions.
  • Etching (if necessary): For very smooth brick surfaces, etching with muriatic acid may be recommended to create a rough texture for better paint adherence. This should be done cautiously, following safety protocols and manufacturer guidelines.

After cleaning and repairs, allow the brick to dry for at least 48 hours, as moisture trapped beneath paint can cause peeling and blistering.

Selecting the Right Paint and Primer for Brick

Choosing the appropriate paint and primer is critical to ensure longevity and maintain the brick’s structural integrity.

For primers:

  • Masonry Primer: Use a high-quality, penetrating masonry primer to seal porous brick and enhance paint adhesion.
  • Stain-Blocking Primer: If the brick has stains or efflorescence risk, apply a stain-blocking primer to prevent discoloration.

Apply primer evenly and allow it to dry completely before painting.

Applying Paint to Brick Surfaces

The application technique influences the finish and durability of painted brick.

  • Tools: Use a high-quality nylon or polyester brush for detailed work and a roller with a thick nap (3/4 inch or more) for large surfaces. A paint sprayer can also be used for even coverage but requires masking of surrounding areas.
  • Painting Technique: Start by brushing paint into crevices and mortar joints to ensure full coverage. Then use a roller to cover flat surfaces. Apply paint in thin, even coats rather than thick layers to avoid drips and peeling.
  • Number of Coats: Typically, two coats of paint are recommended for optimal coverage and durability. Allow the first coat to dry fully before applying the second coat.
  • Drying Time: Follow the paint manufacturer’s recommended drying times between coats and before exposing the brick to moisture.
