How to Paint the Exterior of Your Home Using a Sprayer

If you’re a homeowner who’s looking to paint the exterior of your home, you may be wondering if an exterior spray gun is the best option for your home improvement project.

In this blog post, we’ll talk about how to use a sprayer to paint your house and the pros and cons of using this method. As a professional painter, I can guarantee that using a sprayer will help you achieve a smooth finish while also reducing the amount of time it takes for you to complete the painting project in less than half the time of rolling your home’s exterior walls with paint rollers and paint brushes.

We’ll also give you some advice on how to choose the right spray painter for your needs and provide a list of tools you’ll need to get the job done!

What Is An Airless Paint Sprayer?

An airless paint sprayer is a great tool for large projects that uses a pump to force paint through a small tip at high pressure. It’s designed for large areas, like exterior walls of your home and many paint sprayers feature adjustable pressure options so you can control spray and the amount of paint the sprayer applies to your home’s exterior walls.

When it comes to painting the exterior of your home, there is simply no more efficient way to lay a coat of paint over a large surface than with an airless home paint sprayer. However, it is important to note that using an airless paint sprayer will require you to buy 1-2 extra gallons of paint to account for overspray and the extra paint that says in the paint sprayer while in use.

Using a sprayer will reduce the time it takes to paint your home by at least 50%, plus an exterior home paint sprayer can lay an even coat of paint to give your home a smooth finish for a professional-looking paint project.

While a paint spray gun will let you finish the job in no time flat, you should always use caution when spraying. Be mindful of potential hazards in your vicinity, wear proper footwear, and wear other personal protective equipment (PPE) like goggles, gloves, and a respirator when necessary.

Should You Use An Airless Paint Sprayer On Your Home?

Now that you know how an airless sprayer works and what it can do, the next question is whether or not you should use one on the exterior of your home.

There are a few things to consider before deciding if you manually paint your home with a roller and brush, or if you should use a home paint spraying, like:

  • The size of your project: If you have a small project, like a shed or small porch then going through the hassle of renting/buying a paint sprayer might not be worth it. However, if you are painting the exterior of your home then a paint sprayer is well worth the investment.
  • Your budget: Paint sprayers can be a few hundred dollars to rent, so if you have a tight budget then using a sprayer might not be the best option.
  • Project difficulty: Paint sprayers excel at covering large surfaces with paint in a fraction of the time compared to rolling the surface. However, paint sprayers are not efficient when it comes to walls with lots of texture so consider the type of surface you intend to cover before renting a paint sprayer for your next home painting project.

Painting Supplies You Will Need To Spray Your Home’s Exterior

Now that you know whether or not using an airless sprayer is right for your next home painting project, it’s time to gather the proper supplies.

In order to spray paint the exterior of your home you will need:

  • Paint Sprayer: Obviously, you will need a paint sprayer if you want to spray paint your house. You can either purchase one outright starting at around $200, or rent one from a local hardware store for around $50 per day.
  • Paint: You’ll need enough paint to cover the entire surface of your project. Be sure to factor in about 30% more paint when using a sprayer since some of the paint will be lost in overspray.
  • Extension Cord: A standard extension cord should be long enough to reach anywhere on your project from a single outlet. If you don’t have an extension cord, most hardware stores sell them for around $20.
  • Tarp: It’s always a good idea to lay down a tarp to protect any areas you don’t want painted, like sidewalks or plants. You can usually find a tarp at your local hardware store for under $30.
  • Empty buckets: You will need at least two extra empty buckets for priming the paint sprayer and to help with cleanup.
  • Spray shield:  A spray shield is a must to help contain the paint spray. You can purchase a spray shield starting at around $15, or make your own out of cardboard for free.
  • Prep supplies: You will need supplies like painter’s tape and plastic to cover your windows and doors before spraying.

Now that you know everything you need to spray paint the exterior of your home, it’s time to get started!

Be sure to follow all safety precautions while painting and have fun. Remember, an airless sprayer is the best way to quickly achieve an even and professional-looking paint job.

Steps To Spray Your Home With A Paint Sprayer

Now that you know when it is best to use an airless paint sprayer on your home exterior, we will go over the steps of how to spray paint the outside of your house.

Using a paint sprayer can take some getting used to, but once you have the sprayer set up and ready to go you can enjoy an even coat of paint in a fraction of the time compared to rolling and brushing the exterior of your home.

Here are 5 easy steps that you can follow to ensure your home spraying project delivers a professional look.

1. Power Wash Your Home & Remove Loose Paint

The first step is to power wash your home to remove any dirt, dust, or debris that might be on the surface. A power washer will let you hit areas at the top of your home, so you should not use a garden hose in this situation since a hose can’t expel water at a high volume to knock off dirt and debris.

To do this, I recommend using an electric power washer to remove dirt and grime from the side of your home. This is an important process to prepare your home for spraying since a clean surface will improve the adhesion of latex paint to the wall and trim work, and this will help the paint last longer and look better once the project is complete.

While power washing a home, I like to also take note of any areas that need additional prep work like scraping off loose paint or caulking.

It’s important to remember to let your home dry off for at least 72 hours before spraying the exterior of your home. This is to ensure the surface area has sufficient time to dry, so the latex paint adheres to the surface better and to help the paint dry evenly.

2. Prepare Your Home Before Using The Paint Sprayer

Now that your home is clean, it’s time to do any additional prep work like caulking or scraping off loose paint.

This is an important step to do before using a sprayer because you want to make sure the latex paint adheres well to the surface and dries evenly.

Spraying a home requires a bit more prep work than if you were to roll it since the sprayer can leave little beads of paint in unwanted areas. To avoid this I recommend additional prep work like:

  • Tape windows & doors: It’s important to tape off your windows and doors to avoid overspray on these areas. I like to use a dispenser that lays down plastic along with painter’s tape to protect the face of the trim and windows/door areas.
  • Move furniture: Since you will be spraying paint, you need to make sure you move all furniture, rugs, and plants away from the area where you will be working.
  • Cover lights: I like to wrap lights and other items around the house with a sheet of plastic (the same plastic I used to tape windows and doors). This will prevent overspray from covering your lights and helps to eliminate unnecessary touch ups.
  • Prep the house for painting: Like other painting projects, you may need to prep your home’s walls before painting. This includes filling in holes, priming bare wood, and caulking gaps between wood panels.

You should also take this time to set up your sprayer following the manufacturer’s instructions.

This process will vary depending on what type of paint sprayer you are using so be sure to read the manual carefully before getting started.

3. Test Spraying At A Low Pressure

Once your sprayer is all set up and your house is prepared, it’s time to start painting!

But before you begin, I recommend testing your sprayer on a piece of cardboard or scrap wood to get a feel for the paint sprayer and how much pressure you need to use.

You don’t want to start spraying your home only to find out that the paint isn’t covering evenly or that you are using too much pressure (which can cause the paint to splatter).

Once you are comfortable with the sprayer, begin painting your home starting at the top and working your way down. After testing some different pressures, you should start to feel comfortable with the pressure and be confident with the sprayer. Now it’s time to start spraying your home’s exterior!

4. Being Spraying Your Home’s Exterior

Now that you’ve tested the sprayer and are comfortable with how it works, it’s time to start spraying your home’s exterior.

I recommend starting at the top of the house and working your way down. This will help to avoid any drips or runs in the paint, plus you will be able to cover any ladder marks as you work your way down from the top of the home.

Here are some tips to help you achieve a great looking home painting project with an airless exterior paint sprayer:

  • When painting, be sure to spray pattern that overlaps each stroke by about 50% to ensure even coverage. This means that you should be covering some of the previous pass from the opposite direction to ensure even coverage and helps get paint in crevices that you might have missed on the previous stroke.
  • Test spraying with different spray tips to achieve the proper width and thickness for each coat of paint. The spray tip will apply a different thickness of paint, so choosing a sprayer tip that does not cause paint to blotch on the exterior walls of your home will help you achieve a professional look.
  • Always keep your sprayer perpendicular to the wall that you are working on. This will ensure maximum paint coverage.
  • Keep the tip of the sprayer 12 inches from the surface to ensure you don’t cause the paint to blotch.
  • Use long, smooth strokes on each pass with the sprayer to ensure you apply an even coat. This technique is the foundation for a professional finish.
  • Keep a lid on the paint bucket that feeds your sprayer. Not only will this help prevent the paint from drying out, the lid will also prevent debris from getting into the paint and clogging up the suction tube in the sprayer.

You may need to apply a second coat of paint depending on the color you are using and the type of paint (latex vs. oil-based).

If you do need a second coat, I recommend waiting at least 45 minutes before applying another coat of paint over the first layer of paint.

5. Back-Brush Nooks & Crannies

Once you have finished spraying the paint on your home’s exterior, it’s time to back-brush or roll any nooks and crannies with a paint roller and a paint brush that the sprayer couldn’t reach on your house exterior.

Be sure to use a brush (I like a nylon/polyester blend) that is specific for the type of paint that you are using. This type of brush will help to avoid any bristles coming loose and getting stuck in the wet paint.

Also, be sure to use a light touch when back-brushing so you don’t remove any of the paint that has already been applied.
