Planning to paint the exterior of your home? Knowing what to expect can save you time, money, and frustration. Here, we’ll answer some of the most common questions about exterior painting to help you make informed decisions.

Key Takeaways

Estimating paint gallons depends on house size, texture, and paint type.
Exterior house painting projects generally take 3–7 days to complete.
Primer is essential in many cases, depending on the surface condition.
Winter painting is possible with modern low-temperature paints.
Tipping painters is optional but appreciated; guidelines provided.

How Many Gallons of Paint Are Needed to Paint an Exterior House?

Determining how much paint your home requires involves understanding a few factors:

House Size: Larger homes need more paint, naturally.
Surface Texture: Textured surfaces like stucco require more paint than smooth ones.
Number of Coats: Applying multiple coats doubles your paint needs.

According to The Spruce, a general rule of thumb is that one gallon of paint covers 350–400 square feet on smooth surfaces. For example:

1,500 sq. ft. home: Approximately 10–15 gallons, including primer and touch-ups.
2,500 sq. ft. home: Around 20–25 gallons for two coats.

To avoid overbuying, calculate your total square footage and consult your paint manufacturer’s coverage recommendations.

How Long Does It Take to Paint the Exterior of a House?

Painting a home’s exterior is a multi-step process involving preparation, painting, and cleanup. The timeline varies based on factors such as:

House Size and Architecture: Larger homes or those with intricate designs take longer.
Weather Conditions: Rain or high humidity can delay drying.
Preparation Needs: Power washing, sanding, and priming all add to the time required.

Bob Vila notes that most professional painting jobs take 3–7 days from start to finish. This includes sufficient drying time between coats to ensure lasting results.

Does Exterior Paint Need Primer?

Primer is a key step in many exterior painting projects. It helps:

Improve Adhesion: Ensuring the paint sticks to the surface.
Enhance Durability: Extending the lifespan of the paint job.
Create a Uniform Finish: Hiding imperfections and promoting even color.

Sherwin-Williams recommends using primer in cases like:

Painting over bare wood, metal, or masonry.
Covering repaired or previously damaged surfaces.
Switching between dark and light paint colors.

For certain surfaces, modern “paint-and-primer-in-one” products may work. However, for the best results, consult a professional to determine if a standalone primer is necessary.

Can You Paint Exterior in Winter?

Modern advancements have made winter painting more feasible, but it still requires careful planning. Benjamin Moore explains that certain low-temperature paints work at temperatures as low as 35°F.

Key tips for winter painting include:

Choose the Right Day: Aim for dry, sunny weather.
Paint in the Warmest Hours: Typically mid-morning to early afternoon.
Allow Extra Drying Time: Cooler temperatures can slow the drying process.

Although winter painting can be successful, it’s often better to wait for spring or summer for optimal results. A professional painter can help determine if conditions are suitable for your project.

Should You Tip a House Painter?

Tipping is not mandatory, but it’s a thoughtful way to show your appreciation for excellent service. According to Angi, typical tipping practices include:

Cash Tips: $40–$100 per painter is the recommended amount.
Alternative Thank-Yous: Providing lunch, snacks, or beverages during the project.
Positive Reviews: Writing a glowing online review helps their reputation.

If the painters go above and beyond, such as finishing early or handling unexpected challenges, consider tipping to reflect your gratitude.
