While painting brick requires specific preparation and materials, it is a project that a well-prepared DIY enthusiast can accomplish with fantastic results.
Learning how to paint exterior brick house exteriors is about more than just applying a coat of color; it’s about proper preparation, choosing the right products, and using the correct techniques to ensure a durable, long-lasting finish. This guide is designed to walk you through every step, from cleaning the brick to applying the final weatherproof coating. With this expert advice, you can confidently tackle this project and achieve a beautiful, professional-quality transformation for your home.
Why Painting Your Brick House is a Game-Changer
Painting your brick exterior is one of the most impactful ways to modernize your home and increase its curb appeal. It provides a clean, uniform look that can cover up mismatched bricks or old repairs, creating a cohesive and intentional design. Beyond the aesthetic upgrade, a quality paint job acts as a protective sealant against moisture and weather, helping to preserve the integrity of the brick and mortar. This project allows you to completely customize your home’s color palette, reflecting your personal style while adding significant value and a fresh new identity to your property.
7 Step-by-Step Guide: How to Paint Exterior Brick House
Step 1: Inspect and Repair the Brick Surface
Before any cleaning or painting begins, a thorough inspection of your brick and mortar is essential. Walk around the entire house and look for any signs of damage, such as cracks, crumbling mortar joints (repointing), or spalling bricks. Damaged areas can trap moisture, which will lead to paint failure and further deterioration of the brick. Use a wire brush to remove any loose material and repair any cracks or gaps with a high-quality exterior caulk or mortar repair product. Allow any repairs to cure completely according to the manufacturer’s instructions before proceeding. This step is crucial for a lasting paint job.
Step 2: Thoroughly Clean the Brick Exterior
Proper surface preparation is the key to a successful and durable paint finish. The brick must be completely clean for the primer to achieve a strong bond. Use a pressure washer on a low to medium setting to remove all dirt, mildew, efflorescence (white, salty deposits), and loose debris. For stubborn stains or mildew, you may need to use a solution of trisodium phosphate (TSP) or a specialized brick cleaner, scrubbing with a stiff-bristled brush. After cleaning, rinse the entire surface thoroughly with clean water and allow the brick to dry completely, which can take several days.
Step 3: Protect Surrounding Areas with Tape and Plastic
Once the brick is clean and dry, you need to protect all the areas you don’t want to paint. Use painter’s tape and plastic sheeting to carefully mask off all windows, doors, trim, light fixtures, and landscaping. Cover shrubs and garden beds near the house with drop cloths. This meticulous masking process may seem tedious, but it is vital for achieving clean, professional-looking lines and preventing overspray from a paint sprayer from getting onto unintended surfaces. Taking your time on this step will save you a significant amount of cleanup work later on.
Step 4: Apply a High-Quality Masonry Primer
Brick is a very porous material, and applying a primer is a non-negotiable step. A high-quality, breathable masonry primer serves two main purposes: it seals the porous brick to prevent the topcoat from being absorbed unevenly, and it creates a strong bond for the paint to adhere to. Apply one even coat of primer to the entire brick surface. You can use a paint sprayer for the fastest application or a roller with a thick nap (at least 1 inch) designed for rough surfaces. A brush will be necessary to cut in around edges and get into deep mortar joints.
Step 5: Choose the Right Exterior Masonry Paint
For the topcoat, it is essential to use a paint specifically formulated for exterior masonry. Look for a high-quality, 100% acrylic latex paint that is breathable or “vapor-permeable.” This is crucial because brick needs to be able to release any trapped moisture; a non-breathable paint will trap water, leading to blistering, peeling, and potential damage to the brick itself. These specialized masonry paints are also formulated to be more durable and flexible, allowing them to withstand weather and temperature changes. A satin or eggshell finish is often recommended for a slight sheen that is easier to clean than a flat finish.
Step 6: Apply the First Coat of Paint
Now you can begin applying your topcoat. If you are using a paint sprayer, hold it about 10-12 inches from the wall and apply the paint in a consistent, overlapping pattern to ensure even coverage. If you are using a roller, work in small sections, using a “W” or “N” pattern to apply the paint and then going back over it to even it out. This is a key technique in learning how to paint exterior brick house surfaces. Use a brush for cutting in and reaching any areas the roller or sprayer missed. Let the first coat dry completely, following the time recommended on the paint can.
Step 7: Apply the Second Coat for a Durable Finish
A second coat is almost always necessary to achieve full, even coverage and a durable, long-lasting finish. Once the first coat is completely dry to the touch, apply the second coat using the same technique you used for the first. The second coat will cover any thin spots and create a robust weatherproof coating that will protect your brick for years to come. Pay close attention to texture and consistency, ensuring the finish is uniform across the entire house. Taking the time for a second coat is what separates an amateur job from a professional one.
Common Painting Mistakes to Avoid
When painting brick, several common mistakes can hinder the quality and longevity of the finish. Here are a few pitfalls to watch out for:
- Skipping Proper Preparation – Failing to clean the surface thoroughly or neglecting to repair cracks and gaps can prevent the paint from adhering properly, leading to an uneven finish.
- Using the Wrong Paint – Not all paints are designed for brick surfaces. Using inappropriate paint can result in peeling or cracking over time, so always select a paint labeled for masonry or outdoor use.
- Ignoring Weather Conditions – Painting in extreme temperatures, high humidity, or during rainy weather can affect how the paint dries and adheres to the brick.
- Applying Too Thick of a Coat – Overloading the brush or roller can cause drips, uneven application, and longer drying times. Thin, even coats are always the better approach.
- Neglecting to Prime – Skipping a primer, especially on porous surfaces like brick, can lead to poor paint adhesion and require additional coats to achieve adequate coverage.
Avoiding these mistakes will ensure a professional-looking, durable finish that enhances your home’s appearance and protects it from the elements. Take your time with each step, and your effort will pay off in the long run.
Frequently Asked Questions
What Kind of Paint Is Best for an Exterior Brick House?
The best paint is a high-quality, breathable, 100% acrylic latex paint specifically designed for masonry. These are often labeled as “elastomeric” or “masonry” paints. It is crucial that the paint is “vapor-permeable,” which allows moisture to escape from the brick, preventing blistering and peeling. Never use a standard interior or non-breathable exterior paint, as it will trap moisture and damage the brick.
Do I Really Need to Prime the Brick Before Painting?
Yes, priming is an absolutely essential step. Brick is highly porous and will soak up paint like a sponge, leading to an uneven, blotchy finish that requires many more coats of expensive topcoat. A masonry primer seals the brick, creates a uniform surface, ensures strong adhesion, and helps block stains or efflorescence from bleeding through. Skipping primer will almost certainly lead to a failed paint job.
Is It Better to Spray or Roll Paint on Brick?
Both methods work, but they have pros and cons.
- Spraying: This is much faster and provides a more even finish, especially on rough-textured brick. However, it requires more prep work for masking and has a learning curve.
- Rolling: This method is more DIY-friendly and requires less masking. However, it is much more time-consuming and labor-intensive, and it can be difficult to get full coverage in deep mortar joints.
Many professionals will spray the paint on and then immediately “back-roll” it to ensure a perfect finish.
How Long Does Painted Brick Last?
When done correctly with proper preparation and high-quality materials, a painted brick exterior can last for 7-10 years, or even longer. The longevity of the paint job depends heavily on the quality of the prep work, the type of paint used, the local climate, and the amount of direct sun exposure the house receives. Regular cleaning and minor touch-ups can help extend its life.
Can Painting Brick Damage It?
Painting brick can damage it if it is done incorrectly. The biggest risk comes from using the wrong type of paint. If you use a non-breathable paint, it will trap moisture inside the brick. In climates with freeze-thaw cycles, this trapped water can freeze, expand, and cause the face of the brick to spall or crumble. This is why using a high-quality, vapor-permeable masonry paint is so important.
