Do you also need to get your house fresh painted every two months due to the harsh climate? Then you’re not alone. Most of the houses that are near the coastline are victimized by these issues.

When it comes to choosing exterior paints for houses, especially in harsh climates, selecting the right paint type and formulation is crucial for long-lasting protection.

This is why it is important to select an appropriate exterior paint for harsh climate conditions. Especially when you live in regions where the temperature is extreme, heavy rainfalls, high humidity, and intense sunlight are common. 

This guide will walk you through essential factors to consider when choosing exterior paints for houses in harsh climates.

Understanding Your Climate

Considering the local climate is essential in selecting exterior paints for houses that can withstand temperature extremes, humidity, and high UV exposure.

The first step in selecting the right exterior paint for homes is to thoroughly understand your local climate. Here are the primary factors to consider:

Temperature Extremes

Evaluate temperature ranges in your area. Do you experience blistering heat during the summer months or frigid temperatures in the winter? Different paints respond differently to variations in temperature.

  • Extreme Heat

High temperatures can cause paint to fade quickly and may lead to peeling or blistering. Look for paints specifically formulated to resist heat and UV radiation.

  • Cold Weather

In areas where temperatures drop significantly, you need paint that can remain flexible. Brittle paint can crack, leading to moisture infiltration and further damage.

Humidity Levels

High humidity can cause various problems, including mold and mildew growth. Humid climates require paints that are resistant to moisture.

  • Mildew-Resistant Formulations

Look for paints that include mildewcides to prevent fungal growth. These paints are especially beneficial in coastal areas or regions with frequent rain.

UV Exposure

Regions with high levels of sunlight require paints that can withstand UV radiation.

  • Fade Resistance

Paints that contain UV inhibitors are crucial for preventing fading and maintaining vibrant colors.

Precipitation

Take into account the quantity and nature of precipitation that your area experiences.

  • Heavy Rainfall

In regions prone to heavy rains, choose paints with waterproof properties that can repel water and prevent damage to underlying surfaces.

  • Snow and Ice

In snowy climates, look for paints that can endure freeze-thaw cycles without cracking or peeling.

Types of Exterior Paints

Different types of exterior paints for houses offer unique benefits, from mildew-resistant options for humid climates to UV-resistant choices for sunny regions.

Different types of exterior paints for wood offer unique benefits and drawbacks. Here’s a closer look at the main types:

  1. Acrylic Paint

Benefits

  • Versatile: Acrylic latex paints are suitable for various surfaces, including wood stucco and masonry.
  • Durable: They provide excellent adhesion and flexibility, which helps them withstand temperature fluctuations.
  • Mild-resistant: Most acrylic paints come with additives that resist mold and mildew, making them ideal for humid environments.
  • Acrylic paints are easy to clean with soap and water.

Considerations

While they can be slightly more expensive than traditional paints, their longevity and durability justify the cost.

2. Oil-Based Paint

Benefits

  • Durability: Oil-based paints provide a tough, long-lasting finish and excellent adhesion to surfaces.
  • Smooth Finish: They level out beautifully, providing a smooth and even surface.

Considerations

Oil-based paints can take longer to dry and may become brittle in extreme temperatures. They also emit strong odors and require mineral spirits for cleanup, making them less user-friendly.

3. Elastomeric Paint

Benefits

  • Flexibility: This paint expands and contracts with temperature changes, making it perfect for regions with extreme temperature variations.
  • Waterproofing: Elastomeric paint forms a thick rubber-like film that can fill small cracks and provide a waterproof barrier.

Considerations

Due to its thickness, elastomeric paint may require more extensive preparation and application techniques. It can also be more expensive than standard acrylics.

  1. Specialty Paints

Speciality paints are formulated for specific challenges:

  • Mildew-Resistant Paints: These contain additives to prevent mold growth and are ideal for humid areas.
  • Rust-Inhibiting Paints: Perfect for metal surfaces exposed to moisture, these paints help prevent corrosion.
  • Energy-Efficient Paints: Some paints reflect sunlight, helping to keep homes cooler and reduce energy costs.

Choosing the Right Finish

The finish you choose for exterior paints for houses can significantly impact durability and appearance, making it essential to select a finish suitable for your climate and style.

The finish of your exterior paint for engineered wood can significantly impact both the appearance and durability of your property. Here are common options:

Matte Finish

  • Pros: This hides imperfections and creates a flat appearance.
  • Cons: It is less durable and harder to clean; it is not recommended for high-traffic areas.

Satin Finish

  • Pros: Offers a balance of durability and aesthetic appeal; easy to clean and ideal for most surfaces.
  • Cons: It may not hide imperfections or matte finishes.

Semi-gloss and Gloss Finishes

  • Pros: Highly durable and wash-resistant, making them perfect for trim doors and areas prone to wear and tear.
  • Cons: Can highlight surface imperfections and may require more surface preparation.

Preparing Surface 

Proper preparation is key to ensuring exterior paints for houses adhere well and protect against moisture, especially in harsh weather conditions.

Proper surface preparation is essential for achieving the best results with your exterior paint. Here are key steps to follow:

Cleaning

  • Remove Dirt and Debris

Use a pressure washer or scrub with mild detergent to clean the surface thoroughly.

  • Mold and Mildew Removal

Treat areas with mold or mildew using a mixture of bleach and water or a commercial cleaner designed for this purpose.

Repairing Damages

  • Fill Cracks and Holes

Use caulk or filler to repair any cracks, holes, or surface imperfections.

  • Sand Surfaces

Sanding ensures a smooth finish and helps the paint adhere better.

Priming

  • Choose Right Primer

For surfaces exposed to harsh weather, use a high-quality primer that suits your paint type. Primers improve adhesion and provide a barrier against moisture.

Application Techniques

Applying exterior paint correctly can enhance its performance and longevity.

Timing

  • Check Weather

Ensure that you are painting on a dry day with mild temperatures. Avoid painting in direct sunlight or during high humidity.

Use Right Tools

  • Brushes vs. Rollers

Use brushes for detailed work and rollers for larger areas. Consider using a sprayer for smooth finishes on vast surfaces.

Apply Multiple Coats

  • Two-Coat Application

For best coverage and durability, apply at least two coats of paint. Allow each coat to dry thoroughly before applying next.

Pay Attention to Edges and Trim

  • Detail Work

Ensure that you properly paint edges and trim, as these areas are often more susceptible to weather damage.

Conclusion

Choosing the right exterior paint for harsh climates requires careful consideration of various factors, including climate conditions, paint types, finishes, surface preparation, and application techniques. 

Investing in high-quality exterior paints for houses is vital for ensuring long-term beauty and protection, particularly in regions with challenging climates.

By understanding specific challenges posed by your environment, you can select paint that not only enhances the beauty of your home but also protects it from elements for years to come. Investing in high-quality materials and proper application methods will pay off in the long run, saving you time and money on future maintenance and repairs.
