The Homeowner’s Guide to Exterior Painting

Exterior painting is one of those projects that can completely transform the look of your home- and yes, you can absolutely do it yourself. From knowing when to repaint to getting the prep work just right, this guide will walk you through everything you need to know to get started.

Before getting stressed about starting an exterior painting project, it’s important to assess whether your home actually needs it. Here are a few signs to watch out for:

  • Peeling or flaking paint: Check for paint that’s coming off your siding, trim, or doors.

  • Fading colors: UV rays break down paint pigments over time, causing dull or uneven color.

  • Cracked caulking: Failing caulk can let moisture seep into your home; it should be checked along with the paint to see if it needs reapplying.

  • Exposed wood or bare patches: If your siding or trim shows bare spots, it needs fresh protection.

  • Mildew or stains: If you’re seeing stains or mildew, your home may need a bit more attention than initially planned- they can signal deeper moisture problems.

Most exterior paint jobs last anywhere from 5 to 10 years, depending on the material of your house, the climate you’re in, and the quality of previous applications. If you know that it’s been a while since your last coat, it might just be time! 

Step-by-Step Prepping for Exterior Painting

Proper prep work is crucial when it comes to a successful, long-lasting paint job. Skipping steps might save you time right now, but can eventually lead to peeling, uneven finishes, and premature wear. Here's how to do it right:

1. Inspect and Repair

You’ve already done a basic inspection, so now it’s time to hone in on any problem areas and repair them! Walk around your home and take a look at the siding, trim, eaves, and doors, taking note of any cracks, rot, or loose materials. Make any necessary repairs before painting.

2. Clean Surfaces

Use a garden hose, pressure washer (on a low setting), or scrub brush with soap and water to remove dirt, dust, mildew, and cobwebs. Let everything dry completely.

3. Protect Your Landscaping and Other Fixtures

Use drop clothes and plastic sheeting to cover nearby plants, outdoor lighting, and walkways. Remove or mask any hardware and trim that you don’t want painted.

4. Scrape off Old Paint & Sand

Use a paint scraper or wire brush to remove any peeling or flaking paint; sand rough or uneven areas to create a smooth surface for the new paint to stick.

5. Prime your Surfaces

A high-quality exterior primer helps your topcoat adhere correctly and provides a smoother finish.

6. Use the Right Paint

Use paint formulated specifically for exterior painting. Pay attention to finishes that match your style and the function of the surfaces you’re painting (for example, satin or semi-gloss for trim, flat or low-sheen for your siding).

Tips for a Successful Exterior Painting Project

Now that your home’s exterior is cleaned, prepped, and primed, it’s time to paint! Before you dive in headfirst, take a moment to review these tips. They’re quick to follow and make a big difference in how your project turns out.

  • Pick the right weather. Ideal conditions for exterior painting are mild temperatures (50-85°F) with low humidity and no rain in the forecast for at least 24 hours.

  • Work top to bottom. Start painting from the highest points of your house and work your way down.

  • Use quality tools. Invest in good brushes, rollers, extension poles, and ladders for safety and better results.

  • Don’t rush. Allow each coat to dry completely before applying the next.

  • Mix paint for consistency. If you're using multiple cans of the same color, combine them in a larger bucket to avoid slight color variations.

FAQs About Exterior Painting

Do I have to remove the old paint, or can I just paint over it?
You can paint over existing paint if it’s in good condition. Just be sure to clean and lightly sand it first. Any peeling or damaged paint has to be removed.

What’s the best time of year for exterior painting?
Anywhere from late spring through early fall can work, but the Pacific Northwest can make exterior painting a bit more tricky. Try to time your project in a dry stretch with mild temperatures, keeping an eye on humidity levels. 

How long should I wait between coats?
Check your paint can for drying times. Generally, wait at least 4-6 hours between coats, longer in humid conditions.

Do I need to paint everything at once?
Not at all! You can break the job into sections (e.g., front, sides, back) over several weekends.

How much paint will I need?
It depends on the size of your home and the type of surface. As a general rule, one gallon covers about 350 square feet. Your paint store can help you calculate your needs when you’re buying the paint!
