Interior vs Exterior Painting – What You Need to Know in Wellington

1. Introduction

When planning a home painting project, it’s easy to think that paint is paint—but interior and exterior painting are completely different tasks.

In Wellington, the coastal climate, high winds, and moisture levels make choosing the right paint, tools, and preparation methods critical for long-lasting results.

Whether you’re refreshing your living room or repainting the exterior of your weatherboard home, understanding the unique requirements of each project will save you time, money, and frustration.

In this guide, AAA Painters explains the key differences between interior and exterior painting, the challenges each presents, and how to get the best results for your Wellington home.

2. Interior Painting: Comfort and Aesthetics

Interior painting focuses on appearance and comfort, creating welcoming and stylish living spaces.

Key considerations include:

• Surface prep: Cleaning, sanding, and repairing walls for a smooth finish.
• Low-odour paints: Ideal for ventilated rooms, reducing fumes and drying time.
• Colour selection: Influences mood, lighting, and room size perception.

Common challenges in Wellington homes:

• Humidity in kitchens and bathrooms, which may require moisture-resistant paints.
• Older plaster walls that need extra prep to prevent peeling.

AAA Painters Tip: Use washable, durable paints for high-traffic areas and softer finishes in bedrooms and lounges.

The goal? A beautiful, uniform finish that enhances your home’s interior without strong odours or mess.

3. Exterior Painting: Protection Against the Elements

Exterior painting is all about protection and durability.

In Wellington, your home faces:

• Salt-laden air, which can corrode metal and flake paint.
• Strong winds, causing dust and debris to cling to wet paint.
• UV exposure and rain, leading to fading and moisture damage.

Exterior paint requirements:

• Weather-resistant, UV-protected paints for long-lasting colour.
• Thorough surface prep including scraping, sanding, and priming.
• Timing around weather for proper drying and adhesion.

AAA Painters Tip: Schedule exterior work during stable, dry conditions and use premium primers for timber and metal surfaces to prevent premature wear.

A well-executed exterior paint job not only boosts curb appeal but also extends the life of your home’s exterior materials.
