What is Exterior Acrylic Paint?

Exterior acrylic paint is a durable, water-based paint designed to protect and decorate outdoor surfaces. It is commonly used on exterior walls, masonry, wood, fences, sheds and garden furniture.

Exterior acrylic paint is popular because it offers weather resistance, good adhesion and a flexible finish that helps withstand changing outdoor conditions. Unlike ordinary interior paint, it is formulated for exposure to sunlight, rain and temperature changes.

Whether you're painting a garden fence, refreshing exterior masonry or giving outdoor furniture a new look, this guide explains what exterior acrylic paint is, where to use it, how to apply it and how long it lasts. You'll also discover how to choose the right exterior paint for your project and explore the range of colours available from Hemway.

What is it Used For?

Exterior acrylic paint is highly versatile and can be used for a wide range of outdoor applications. Common uses include:

  • House Exteriors: Exterior acrylic paint is often used on house exteriors, including walls, trims, and doors. It provides a durable finish that can stand up to harsh weather conditions.
  • Fences and Gates: Wood, metal, or composite fences can be coated with acrylic paint to protect them from moisture, UV rays, and wear.
  • Outdoor Furniture: It's perfect for refreshing outdoor furniture like wooden benches, metal chairs, and garden tables.
  • Decks and Patios: Acrylic paint can be applied to wood or concrete surfaces such as decks and patios to provide long-lasting protection and enhance appearance.
  • Exterior Decor: Any outdoor decorative items, from plant pots to birdhouses, can be painted with acrylic paint for a fresh, weather-resistant finish.

The flexibility of exterior acrylic paint makes it suitable for almost any outdoor surface, from wood and metal to masonry and concrete.

How to Apply Exterior Acrylic Paint: Step-by-Step

Applying exterior acrylic paint correctly helps achieve an even finish and improve long-term durability.

Step 1: Clean and Prepare the Surface

Remove dirt, dust, grease, loose paint and any flaking material. Allow the surface to dry completely before painting. For wooden surfaces, sand rough areas and remove any sanding dust. Repair damaged areas before continuing.

Step 2: Apply Primer if Required

Bare, porous or previously untreated surfaces may need a suitable exterior primer.

Step 3: Choose the Right Weather Conditions

Paint during mild, dry weather. Avoid painting when rain, frost or extreme temperatures are expected during application and drying.

Step 4: Stir the Paint Thoroughly

Open your exterior acrylic paint and stir thoroughly to ensure an even colour and consistency. Use a suitable brush or roller for the surface you're painting.

Step 5: Apply the First Coat

Apply the paint evenly, working in manageable sections. Avoid overloading your brush or roller, as this can cause drips and an uneven finish.

Step 6: Allow the Paint to Dry

For Hemway Exterior Paint, leave at least 2 hours between coats.  Drying times may vary depending on temperature, humidity and the surface.

Once complete, allow the paint to cure before exposing the surface to heavy use or cleaning.

How to Clean Up Exterior Acrylic Paint

Cleaning up is relatively easy, thanks to its water-based formulation. Here are the steps for cleaning up your tools and work area:

  1. Brushes and Rollers: Wash your brushes and rollers with warm soapy water. Rinse them thoroughly until the water runs clear and no paint remains in the bristles or roller fibres.
  2. Surfaces: If you've accidentally splattered paint on any surfaces, clean it up with a damp cloth while the paint is still wet. For dried paint, you may need a paint remover or mild solvent.
  3. Hands: Hemway paint is non-toxic and can be cleaned from your skin with soap and water.

One of the advantages of acrylic paint is how easily it can be cleaned with water before it dries, making it convenient for both DIYers and professional painters.

Is it Water-Based?

Yes, exterior acrylic paint is water-based. Unlike oil-based paints, which require solvents like turpentine for clean-up, acrylic paints are formulated with water as the primary solvent. This makes them easier to work with and much more environmentally friendly.

Its water-based nature also means that it dries quickly, allowing for faster project completion. Despite being water-based, it is highly durable once it dries and offers excellent resistance to the elements, making it perfect for outdoor use.

Can Acrylic Paint Be Used Outside?

Yes, paint like Hemway Exterior Paint can be used for outdoor projects. In fact, it is one of the best types of paint for outdoor applications. Its weather-resistant properties, flexibility, and ability to adhere to various surfaces make it ideal for painting the exterior of homes, fences, garden furniture, and more.

Exterior acrylic paint is specially formulated to withstand the sun’s UV rays, rain, wind, and other outdoor elements. It is also resistant to fading and cracking, which ensures a long-lasting finish. If you're planning a project that involves painting an exterior surface, acrylic paint is a reliable and durable choice.

Can I Use Exterior Acrylic Paint on Wood?

Yes, exterior acrylic paint can be used on wood, and it’s a great option for outdoor wood surfaces like decks, fences, sheds, and wooden furniture. Acrylic paint adheres well to wood, providing a smooth and even finish while offering protection against moisture and UV damage.

Before applying exterior acrylic paint to wood, it’s important to properly prepare the surface. Sand the wood to remove any rough spots or old paint, and make sure the surface is clean and dry. Priming the wood with an exterior primer before painting will also help the paint adhere better and increase the longevity of the finish.

Is Matt Acrylic Paint Waterproof?

Matt acrylic paint provides a flat, non-reflective finish, but is it waterproof? The answer is both yes and no. Once cured, matt exterior acrylic paint is water-resistant, meaning it can withstand rain and moisture to a degree. However, it is not completely waterproof in the sense that it will repel water indefinitely.

For outdoor projects that will be exposed to significant moisture, it’s recommended to apply a waterproof sealant over the matt acrylic paint to provide additional protection. This will help keep the surface protected from water damage, extend the life of the paint, and preserve the matt finish.

Does Outdoor Acrylic Paint Need to Be Sealed?

While durable and water-resistant, sealing it can further protect it from the elements and ensure a longer-lasting finish. A sealant can protect against moisture, UV rays, and wear, making it especially important for high-traffic areas or surfaces exposed to extreme weather conditions.

If you’re applying exterior acrylic paint to surfaces like wooden fences, garden furniture, or decks, it’s a good idea to seal the paint with a clear, weather-resistant sealant. This will provide extra protection and keep the paint looking fresh for longer.

How Long Does Exterior Acrylic Paint Last?

To maximise the lifespan of your exterior paint, proper surface preparation is essential. This includes cleaning, sanding, and priming the surface before painting. Additionally, applying a weatherproof sealant can help extend the life of the paint and keep it looking vibrant for many years.

Additional Tips 

Here are some additional tips to ensure your exterior acrylic painting project is a success:

  • Choose the Right Weather: For the best results, apply exterior acrylic paint in mild, dry weather. Avoid painting on days when rain is forecasted, or when the temperature is too hot or too cold, as this can affect the drying process.
  • Use Quality Brushes and Rollers: Invest in high-quality brushes and rollers to ensure a smooth and even application. Cheap tools can result in streaks and an uneven finish.
  • Apply Multiple Coats: For maximum durability and colour vibrancy, apply two or more coats. Be sure to let each coat dry completely before applying the next.

Conclusion

Exterior acrylic paint works well for many outdoor projects. It offers excellent coverage, resists weathering, and creates a durable finish. Use it on home exteriors, fences, or outdoor furniture for a long-lasting and polished look. Proper preparation, application, and maintenance ensure it protects and enhances your outdoor spaces for years.
