Painting Your Home Interior in Queensland: Products, Prep, and Getting a Professional Finish

Choosing the Right Paint for Queensland

Queensland's humidity (often 70–85% in summer) and temperature swings demand moisture-resistant, mould-inhibiting paint. For bathrooms and kitchens: use a dedicated bathroom paint (Dulux Wash & Wear Bathroom or Taubmans Endure Bathroom) — not standard interior paint. For living areas and bedrooms: a premium low-VOC acrylic in low-sheen or satin finish suits QLD homes well. Avoid flat/matt finishes in humid rooms — they absorb moisture and grow mould.

Preparation is 80% of the Job

Fill cracks and nail holes with flexible filler (Selleys No More Gaps for corners and joints, Spakfilla for flat surfaces). Sand smooth when dry. Remove any mould with a sugar soap and bleach solution — never paint over mould. Clean all surfaces with sugar soap to remove grease and dust. Fill, sand, and sugar soap in that order, then let walls dry completely before painting.

Prime: Don't Skip It

New plasterboard, repaired areas, or previously unpainted surfaces must be primed. Use a sealer/primer that suits the surface type. On previously painted walls in good condition, a quality paint + primer combo (like Dulux Wash & Wear +Primer) can work. In Queensland's humid areas, use a mould-resistant primer. Skipping primer on bare surfaces almost always shows through as uneven sheen and poor coverage.

The Right Tools Make a Huge Difference

Invest in a quality roller (25mm nap for textured walls, 12mm for smooth), a good angled brush (65mm for cutting in), a roller tray, painter's tape, drop sheets, and an extension pole. Cheap rollers leave fibres in the paint and create a stippled finish. For large rooms, a 230mm wide roller cuts job time in half. A good 65mm angled brush lets you cut in cleanly without taping every edge.

Cutting In: The Skill That Separates DIY from Pro

Cutting in means painting the edges (where walls meet ceilings, cornices, trim, and other walls) with a brush before rolling. Load the brush and tap off excess — don't wipe the brush on the rim or you'll dry it out. Use the angled tip and draw a steady line with your forearm resting against the wall for control. Work in 50cm sections. In Queensland's heat, cut in one wall at a time and roll immediately — you want a wet edge where the brush meets the roller.

Rolling: Technique for a Smooth Finish

Use a W or M pattern — roll diagonally across the wall, then back-roll vertically without reloading to even out the finish. Maintain a wet edge and work wall to wall without stopping in the middle. Two thin coats are always better than one thick coat. In Queensland's humidity, allow full cure time between coats (2–4 hours in summer heat is usually enough, but longer in humid conditions — feel the paint, don't guess).

Queensland-Specific: Heat and Humidity Tips

Paint in the morning before the afternoon heat peaks — above 35°C, paint dries too fast and shows lap marks. Close windows on humid days to slow drying and avoid dust settling in wet paint. Never paint in direct sunlight. If you see condensation on walls in the morning (common in coastal QLD), wait for it to evaporate completely before starting.

💡 Expert Tips from EIJ Construction

• →Always buy 10% more paint than calculated — colour-matching a second tin is hit and miss
• →In QLD bathrooms, use a mould-inhibiting primer even if you can't see mould — it's often microscopic
• →Store leftover paint in a sealed container with a piece of glad wrap pressed against the surface to prevent skinning
• →Remove painter's tape while the final coat is still slightly tacky — pulling off dry tape can peel the paint edge
• →A quality brush is the single best investment — a Purdy or Wooster brush used carefully outlasts 10 cheap brushes
