What Paint to Use Inside a Summer House?

Turning your summer house into a space that embodies the essence of the season is never a bad idea. However, there’s one crucial element that is often overlooked: the choice of paint.

The right paint plays a role in creating the perfect ambience for your seasonal getaway. This applies to both the outside and inside of the structure.

In this guide, we’ll help you select the ideal interior paint for your summer retreat. Read on and discover how to make it truly enchanting with the stroke of a paintbrush.

1. Consider the garden summer house’s purpose

The purpose of your outdoor structure should guide your choice of interior paint. Are you envisioning a serene space for relaxation? A productive office conversion for your log cabin summer house? Or a vibrant playhouse for kids? The paint you select can make all the difference.

For a relaxation haven, soothing and calming hues like soft blues or muted pastels are ideal. In contrast, a garden office may benefit from energising, focus-enhancing colours. And if it’s a playroom, playful shades can stimulate creativity.

2. Choose the right paint finish

When selecting paint for your BillyOh summerhouse, understanding the various finishes is paramount. Paint finishes include matte, satin, and gloss, each with unique characteristics.

  • Matte finish: Offers a flat, non-reflective surface, ideal for a rustic or cosy look. However, it may be less resistant to stains and scuffs.
  • Satin finish: Strikes a balance with a soft sheen, suitable for most spaces. It’s easy to clean and offers moderate durability.
  • Gloss finish: Shiny and reflective, it’s highly durable and easy to clean. This makes it perfect for high-traffic areas like kitchens and bathrooms.

Consider satin for walls and matte for ceilings. Meanwhile, gloss is used for trim and doors to achieve aesthetics and durability.

3. Select suitable colours

Colours have a psychological impact, and in a summer house interior, shed paints set the mood. For one, coastal shades like soothing blues and seafoam greens can give off a breezy, beachy vibe. Pastels like soft pinks and pale yellows can create a light and airy feel.

However, don’t forget your personal preferences. Choose colours that resonate with you and align with the desired ambience. Be it tranquil, vibrant, or somewhere in between. After all, your summer house should be a reflection of your unique style and relaxation needs.

4. Pay attention to the climate

In humid environments, moisture resistance is important. High humidity can cause paint to peel and blister over time. Opt for paints labelled as “moisture-resistant” or “mildew-resistant” for areas prone to dampness.

For diverse climates, choose paints designed for versatility. A shed paint, for one, with excellent adhesion, can withstand varying temperature and humidity levels. The paint must withstand the challenges posed by your insulated summerhouse’s climate. Whether it’s the heat of a coastal retreat or the chilly nights of a mountain escape.

5. Prep and application

Before you pick up that paintbrush, proper preparation is key. Start by cleaning and sanding surfaces to ensure a smooth canvas for your paint. Repair any cracks or imperfections with filler and prime where needed.

When it comes to application, employ steady, even strokes. Begin with the ceiling and work your way down to avoid drips. Use a roller for large areas and brushes for corners and trim.

Equally important are the tools you use. Invest in high-quality brushes, rollers, and other equipment. Not only do they make your job easier, but they also yield a smoother, more professional finish. Don’t underestimate their impact on the final result!

6. Maintenance and longevity

To keep your interior looking fresh, regularly dust and wipe down walls. Address stains promptly to prevent them from setting. A fresh coat of paint can breathe new life into a space when needed.

Consider the longevity of different paint types and finishes. Generally, gloss finishes tend to be more durable and easier to clean. Meanwhile, matte finishes may require touch-ups sooner. Factor in the wear and tear experiences of your unit when planning for maintenance.


In your summer house, every brushstroke of paint can make a difference. Your choice of colours, finishes, and attention to detail can turn it into a cherished haven. The paint should harmonise with your purpose, adapt to the climate, and echo your style.

With preparation, application, and maintenance, it will continue to radiate charm for years. So, embrace the brush and palette, and let your summer sanctuary be a canvas of comfort and joy.
