Discover how airless sprayers streamline exterior wall painting. Achieve consistent coverage, reduce manual labor, and complete large projects faster while maintaining a professional, high-quality finish.

Exterior Walls: Save Time and Get Professional Results

Painting exterior walls can feel like a massive project. Between prepping, taping, and climbing ladders with brushes or rollers, most homeowners and small contractors spend days trying to achieve an even coat. The good news? There’s a faster, smarter way. With an airless paint sprayer, you can transform exterior walls in a fraction of the time, while still getting professional-grade results.

Why Use an Airless Sprayer for Exterior Walls?

Exterior surfaces are typically larger, more textured, and exposed to harsh weather conditions. That makes painting them with rollers or brushes both slow and inefficient. Airless sprayers solve these challenges by:

• Speed: Cover large areas up to 10 times faster than traditional methods
• Even Coverage: Consistent spray patterns reduce streaks and roller marks
• Durability: Sprayers apply a thicker, more uniform coat that protects against sun, rain, and dust
• Versatility: Handle brick, plaster, cement, and textured surfaces with ease

Instead of spending your entire weekend on one wall, you can paint the whole exterior of a medium-sized home in a day.

Step 1: Prepare Your Surfaces

The secret to a lasting exterior paint job is preparation. Start by washing walls with a pressure washer or hose to remove dirt and mildew. Scrape away flaking paint and repair cracks with filler. Mask off windows, gutters, and plants with painter’s tape and plastic sheeting. This ensures your sprayer only hits the surfaces you want painted.

Step 2: Choose the Right Paint

For exteriors, acrylic latex paints are the go-to choice. They are flexible, weather-resistant, and dry faster than oil-based options. If your walls are textured or porous, look for high-build coatings that provide extra coverage and durability.

Step 3: Select the Right Sprayer and Tip

Airless sprayers come with interchangeable spray tips, each designed for a specific application. For exterior walls, a wider spray fan (usually a 515 or 517 tip) delivers better coverage on large, flat surfaces. Smaller tips are ideal for trim and detail work.

Spra-co offers a range of sprayers - from entry-level wheeled models for homeowners to rolling-chassis machines for contractors - designed to handle exteriors with ease.

Step 4: Spraying Technique

Hold the sprayer about 12 inches from the wall. Move in smooth, overlapping strokes, keeping your arm steady and parallel to the surface. Start with horizontal passes, then switch to vertical ones (“cross-hatching”) for even coverage. Avoid swinging your wrist, as this can cause uneven thickness at the edges.

Step 5: Work Smart, Not Hard

Unlike brushes or rollers, which force you to stop frequently for reloading, sprayers let you work continuously. Tackle one side of the house at a time, and don’t forget to back-roll textured areas to ensure paint penetrates deeper into cracks and crevices.

Step 6: Clean and Maintain

Cleaning is as important as painting. Flush the sprayer with water (for water-based paints) or the appropriate solvent (for oil-based paints). Proper maintenance keeps your equipment in good condition and ensures consistent performance on the next job.

Time and Cost Savings

Using an airless sprayer doesn’t just save time; it can also cut costs. Less paint is wasted compared to rollers, and because coverage is more uniform, fewer coats are needed. For small contractors, this means completing more jobs in less time. For homeowners, it means professional results without paying professional fees.

The Professional Finish Advantage

Exterior walls are exposed to everything — sun, rain, wind, and pollution. An airless sprayer doesn’t just apply paint; it creates a protective shield. Smooth coverage means fewer gaps where moisture can seep in, extending the life of your paint job by years.

Is an Airless Sprayer Worth It?

Absolutely. Whether you’re a homeowner looking to refresh your exterior or a small contractor working on multiple projects, the return on investment is clear. Faster application, superior finish, and long-term durability all add up to a smarter, more efficient approach to painting.
