The Art and Science of External Painting: A Guide by Brisbane Professional Painters

Exterior paint is the first line of defence for your home against the elements, shielding it from the blistering sun, relentless rain, and unpredictable temperature shifts.

Modern paint chemistry has revolutionised the durability of exterior paints, allowing surfaces that once required repainting every two or three years to now withstand a decade or more.

However, even with advanced paint formulations, there are common challenges that can arise, especially when conditions are less than ideal or when preparation and application fall short.

Common Risks for Exterior Paintwork:

• Peeling Paint - Exposed timber or masonry beneath can result if moisture becomes trapped inside the wall. Issues like unsealed joints, worn sealant, leaks, or inadequate ventilation can contribute. Paint applied before proper drying, or using incompatible coatings (like acrylic over oil-based paint), can cause blistering or peeling. A specialised primer and proper surface prep are non-negotiable.

• Colour Fading - Over time, exposure to UV and heat - common under Brisbane’s sun - can make exterior colour dull or uneven. Low-quality paint or interior-grade paints worsen this. Using high-quality exterior paints designed for UV resistance and weather durability helps maintain colour and gloss year after year.

• Mould & Mildew - Timber and damp or shaded surfaces are especially vulnerable. If bare wood is left unprimed or paints without mould retardants are used, new paint may quickly become stained or degraded. Proper sealing, high-quality exterior paints, and moisture-resistant products help prevent this risk.

• Cracking & Rust Staining - Using a hard coating over old flexible paint, or applying new coats before previous ones fully cure, can cause cracking. For homes with non-galvanised or rust-prone metal fixtures, rust bleeding through can stain the topcoat, especially if nail heads weren’t countersunk or primed. The right primers and careful surface preparation before painting are crucial.

At Brisbane Professional Painters, our commitment goes beyond applying paint, it’s about safeguarding your home against all these elements. We use weather-resistant systems, professional-grade primers, and strict prep work to help your exterior stand the test of time.

Why Preparation and Paint Quality Matter

The difference between a paint job that lasts a couple of years and one that stands strong for a decade or more comes down to prep + product + technique.

• We always start with a thorough inspection - checking for soft timber, peeling old paint, previous water damage, mould, or structural issues.

• Surfaces are cleaned, sanded, filled, sealed and primed where needed before any top coat is applied.

• We only use high-quality exterior paints (from top brands, formulated for UV stability, humidity, and heat), suited for Brisbane’s climate.

• Each coat is applied with care, allowing proper drying, avoiding rush-jobs, and accommodating for weather conditions.
  

This approach ensures the coating adheres correctly, resists peeling, resists moisture and UV damage, and stays looking fresh and protected.

What Good Exterior Painting Looks Like: Benefits You’ll Notice

• Longer lifespan - protection that lasts many years.

• Better colour retention - less fading or chalking under sun exposure.

• Resistance to weather, damp, mould, and rot - essential for coastal and humid Brisbane suburbs.

• Improved curb appeal and home value - a fresh, well-maintained exterior boosts how your home feels and how it’s perceived.

  
  

Thinking of Repainting? Here’s What to Consider

If your home exterior is showing signs - faded paint, cracking, peeling, or uneven colour - it may be time to repaint. Rather than just a quick refresh, doing it properly the first time makes a huge difference.

We recommend:

• Inspecting timber, joinery, and metalwork for signs of wear or rust.

• Choosing a weather-resistant exterior paint system suitable for Brisbane conditions.

• Ensuring all surfaces are properly prepped and primed.

• Considering warranty, insurance, and proper contracting, to give you peace of mind for the years ahead.
