Why local conditions matter in Melbourne

• West and north aspects: higher UV and heat load accelerate fade and film fatigue.
• Leafy/shaded pockets: persistent moisture promotes mould growth and slow drying.
• Bayside/coastal suburbs: salt spray increases corrosion risk on fixings and roof elements.
• Inner-urban arterials: airborne dust and soot impact washability and perceived colour over time.

Bottom line: The right system is not only about colour. It is a match between prep, primer, topcoat chemistry, and exposure.

Interior house painting: finishes that clean easily and hide well

Finish sheen and where it works

• Ceilings: flat/ultra-flat to hide minor defects and glare.
• Walls: low sheen or washable matte for living areas; higher-scrub products for family zones.
• Wet areas: moisture-tolerant systems with mould-resistant binders; ensure external ducting of exhaust fans.
• Trim and doors: satin or semi-gloss for crisp edges and durability.

Primer selection by substrate

• New plaster: dedicated sealer/undercoat to lock porosity and promote even topcoat sheen.
• Previously painted walls: clean, dull, and patch prime repairs to avoid flashing.
• Stain-prone areas: stain-blocking primers to prevent tannin, smoke, or water marks telegraphing through.

Colour note: Cooler southern light can make colours read bluer; test swatches vertically, observe morning and evening.

Exterior house painting: protecting the envelope

Surface prep that actually extends life

• Timber: scrape to firm edges, sand feathered transitions, spot-prime bare timber; fix moisture pathways before coating.
• Masonry/render: neutralize salts, repair cracks with compatible fillers, use masonry primers for adhesion and alkali resistance.
• Metal: remove corrosion to bright metal where practical, use appropriate metal primers and topcoats with anti-corrosive pigments.

Coating choices by exposure

• High-UV faces: premium exterior acrylics with strong UV inhibitors and flexible binders.
• Damp/shaded zones: breathable systems with anti-mould additives; prioritize drainage and sunlight access where possible.
• Coastal edges: products specified for salt-mist environments; consider more frequent washdowns to remove deposits.

Detailing matters: End-grain sealing on timber, correct flashing overlaps, and clear weep paths reduce premature coating failure.

Roof painting in Melbourne: when it helps and when it does not

Roof coating is about appearance and weather protection on sound substrates. It is not a substitute for structural repair or waterproofing defects.

Substrate-specific guidance

• Concrete tiles: clean thoroughly, replace broken tiles, re-bed and re-point where needed, then prime and apply roof membranes.
• Metal roofing: address rust, secure fixings, reseal laps; use primers compatible with galvanised or Colorbond-type surfaces.

Thermal and glare considerations

• Lighter colours reflect more solar load; this can reduce summer heat gain.
• Gloss level affects dirt pickup and washability; high gloss can highlight imperfections.

Colour selection that works in real homes

• Undertones: grey-greens calm harsh western sun; warm whites soften cool southern light.
• Sheen and colour interaction: higher sheen appears brighter; plan continuity across adjoining spaces.
• Test strategy: sample boards at least A3, two coats, viewed next to trims and floors under day and night lighting.

Scheduling and cure windows in Melbourne weather

• Exterior cure: avoid painting ahead of rain or heavy dew; respect recoat and through-cure times.
• Interior ventilation: plan safe airflow to speed off-gassing while keeping dust control.
• Roof work: schedule during stable weather windows; confirm safe access, pitch, and harness requirements.

Maintenance rhythm for longer-lasting results

1. Annual inspection: look for chalking, microcracks, and end-grain exposure, especially on sun-beaten elevations.
2. Washdown: gentle exterior clean annually to remove grime, mould, and salt.
3. Touch-ups: seal exposed spots promptly to prevent water ingress and substrate damage.

When to call professionals

• Complex substrates: mixed timber, render, and metal interfaces with flashing and sealant sequencing.
• Access and safety: multi-storey exteriors, steep roofs, or sites near power lines.
• Durability targets: warranty-backed systems, documented prep, and traceable product specs.

Mini checklists

Interior refresh

• Patch and sand repairs smooth; prime patches to avoid flashing.
• Choose washable low-sheen or scrubbable matte for family zones.
• Seal gaps at skirtings and trims before final coats.

Exterior recoat

• Wash down thoroughly; allow dry time.
• Prime bare spots; check end-grain and lower trims.
• Use premium exterior acrylics on high-UV faces.

Roof restoration

• Replace broken tiles or address rust before any coating.
• Confirm primer compatibility with the substrate.
• Schedule during stable, dry weather with safe access planned.
