When choosing an exterior house paint, there are a few factors you need to consider:

The climate: The climate you live in will affect the type of paint you need. If you live in a cold climate, you will need a paint that can withstand freezing temperatures soon after application. Benjamin Moore Aura is my go to in this environment.  If you live in a hot climate, you will need a paint that can withstand high temperatures during application. Benjamin Moore Aura also works well in hot climates as well as Kelly Moore Acryshield.  If you live in a rainy, moist climate you may need a paint that can withstand moisture soon after application.  If it there is a possibility that it will rain, I prefer Sherwin Williams Latitude.

The surface: The type of surface you are painting will also affect the paint that you need. If you are painting a wood surface, then you will need a paint that is designed for wood. Benjamin Moore ArborCoat is a good choice for wood. Another good product for wood is Sherwin Williams Woodscapes. If you are painting a brick surface, you will need a paint that is designed for brick such as H&C Stain.

The color: The color you choose will be a matter of personal preference. However, you should also consider the color of your roof and other exterior elements when choosing a paint color.  If you are painting vinyl siding it is important to use vinyl safe colors. If you do not choose paint colors of a vinyl safe color palette you can destroy your siding on the first hot day as it will warp.

The preferred finish: The finish of the paint will affect the look of your home. A matte finish will give your home a more traditional look, while a glossy finish will give your home a more modern look.  I prefer a flat on stucco surfaces, and satin finish on trim and the body of the house when the house is made of composite materials or Hardy plank.  For accents like shake gables I prefer a flat finish so it looks more consistent with the actual substrate itself.

Once you have considered these factors, you can start shopping for exterior house paint. Here are a few tips for choosing the right paint:

Read the labels: Before you buy a paint, be sure to read the label and TDS (technical data sheet). The label will tell you the type of paint, the color, the finish, and the coverage.  The TDS will give you other important information about the paint.

Apply the paint properly: Once you have chosen a paint, be sure to apply it properly. This will help to ensure that the paint lasts for years to come.  A paint is only as good as the prep work and application. Follow the TDS to get the proper application and so your warranty applies when complete.

Be Aware of the Warranty but: do not take the warranty literally.  No paint will last a lifetime, nor will a 25 year warranty paint last 25 years.  A warranty only gives you an idea of the grade of paint within that manufacture.  Read the warranty very carefully.  If improperly applied the warranty is void.  No warranty will cover fading which is where most paints fail first.
