Walking into the paint aisle can be intimidating. With rows of cans promising different results, it's easy to feel lost. The secret to choosing the right exterior paint isn't complex chemistry — it's about making three straightforward choices. You'll identify your home's surface, select the right type of paint, and pick the perfect sheen for a beautiful, long-lasting finish.

Step 1: Match Your Paint to Your Home's Surface

Before thinking about colour, look at what you're painting. Your home's exterior material has unique needs. Using the wrong paint is like wearing the wrong shoes — it won't perform well and will fail much faster.

Timber Siding — Expands and shrinks with temperature changes. Choose a flexible outdoor timber paint that can move with the wood to prevent cracks and peeling.
Brick & Render — Needs to “breathe” to allow moisture to escape. Use breathable masonry paint or exterior render paint that prevents trapped dampness and blistering.
Vinyl & Fibre Cement — Needs a paint that bonds to smooth, non-porous surfaces. Always clean and prime these surfaces before applying a quality acrylic.

Step 2: Why 100% Acrylic Is Almost Always the Right Answer

Once you've identified your surface, the next choice is paint type. For nearly every exterior project — wood, vinyl, brick — the best choice is a high-quality 100% acrylic latex paint.

100% Acrylic Latex — RECOMMENDED

  • Durable and flexible — expands and contracts with your house
  • Resists cracking and holds colour under years of direct sun
  • Easy cleanup with soap and water

Oil-Based / Alkyd

  • Rock-hard finish but tends to become brittle over time
  • Strong odour — requires mineral spirits for cleanup
  • Only recommended for specific surfaces like metal railings or steel doors
Modern acrylic latex paint gives you lasting protection, vibrant colour, and easy cleanup — making it the smart choice for almost every exterior surface.

Step 3: Picking a Sheen to Balance Looks and Durability

Your final choice is the finish, or sheen. Higher sheens are more durable and easier to clean, but they reveal every surface imperfection. Match the right sheen to the right part of your house.

Satin / Eggshell

  • Best for: Siding & walls
  • Durable enough to resist dirt and moisture
  • Low luster hides minor surface flaws across large walls
  • The top choice for most exterior siding

Semi-Gloss

  • Best for: Trim, windows & doors
  • Tough and wipeable
  • Perfect for high-contact areas
  • Adds crisp definition to architectural details

Flat / Matte

  • Best for: Foundations & low-traffic surfaces only
  • Non-reflective and hides texture
  • Stains easily and is hard to clean
  • Not recommended for walls

Is Expensive Paint Worth It? Price vs. Value

2 Coats Premium paint covers in 2 coats
3–4 Coats Budget paint often needs 3–4 coats for the same result

When you see a $200 tin next to a $100 one, the higher price almost always signals better value. Premium paints contain more high-quality pigments for better coverage and binders that make paint last. A cheap exterior paint is thinner, often requiring three or four coats to do what a quality paint does in two. More importantly, quality paint resists fading and peeling for years longer — saving you from repainting prematurely.

Don't Skip This Step: When You MUST Use a Primer

Even the best paint needs a solid foundation. A primer acts as essential glue, ensuring your new paint sticks properly and won't peel or blister.

1 Bare wood or metal — Raw surfaces are porous and unstable. Primer seals the surface and gives the topcoat a uniform base to bond to.
2 Painting over glossy surfaces — Gloss repels new paint. A primer etches the surface and ensures proper adhesion without peeling.
3 Making a dramatic colour change — Going from dark to light (or vice versa) requires primer to prevent old colours from bleeding through and to achieve even coverage in fewer coats.
Note: “Paint-and-primer-in-one” products are just thicker paints. They work for simple recoats over clean, similar colours — but are not a substitute for a true primer on problem surfaces.

Final Check: Climate & Colour Testing

Damp or shaded areas — Choose a mildew-resistant, weatherproof paint to prevent mould growth on south-facing or tree-shaded walls.
Sunny or hot climates — Consider the paint's Light Reflectance Value (LRV). Lighter colours have a high LRV, bouncing heat away and keeping your home cooler. White exterior paint offers one of the highest LRVs available.

Always test exterior paint samples before committing. Paint a large square on a less-visible wall and observe it at different times of day. Colour chips can be misleading — seeing the colour in real-world light is the only way to be certain.

Your 5-Step Paint-Buying Checklist

1 Identify your surface — Wood, brick, vinyl, render? Each needs a paint matched to its properties.
2 Choose 100% acrylic latex — The go-to choice for almost every exterior surface in Australia.
3 Pick your sheen — Satin/eggshell for siding, semi-gloss for trim and doors.
4 Decide on primer — Bare surfaces, glossy surfaces, or big colour changes all need a separate primer coat.
5 Test a sample first — Paint a large patch on your wall and observe it in morning, afternoon, and evening light before buying in full.
