Quick Answer
Painting a standard bedroom yourself in Melbourne costs $100–$250 in materials versus $400–$900 for a professional painter — a worthwhile saving if you follow a proper prep process. The secret to a professional-looking result is 80% preparation and 20% painting: fill holes, sand, prime where needed, and mask carefully before touching a roller to the wall.
What You’ll Need
| Item | Cost | Where to Buy |
|---|---|---|
| Interior low-sheen or flat paint (10L) | $60–$120 | Dulux at Bunnings or Mitre 10; Haymes at independents |
| Ceiling paint (4L) | $30–$55 | Any hardware store |
| 9mm nap roller x2 | $15–$30 | Purdy or Wooster rollers from Total Tools or Mitre 10 |
| 50mm angled brush | $12–$25 | Any hardware store; avoid cheap brushes — they shed bristles |
| Painter’s masking tape (36mm) | $8–$15 | Frog Tape or 3M Blue tape — worth the premium |
| Drop sheets (canvas or plastic) | $20–$40 | Canvas preferred — plastic is slippery |
| Patching compound and putty knife | $12–$20 | Gyproc or Selleys Spakfilla |
| Sandpaper (120-grit, 240-grit) | $8–$15 | Any hardware store |
| Sugar soap and sponge | $8–$12 | Bunnings or Mitre 10 |
Step-by-Step: How to Paint a Room
Step 1: Prepare the Room
Remove furniture or push it to the centre and cover it. Remove switch plates and power point covers (with the power off at the switchboard). Lay drop sheets covering the entire floor. Good prep at this stage prevents most cleaning problems later.
Step 2: Fill Holes and Sand
Inspect all walls for nail holes, dents, or cracks. Apply patching compound with a putty knife, slightly overfilling each hole. Allow to dry completely (1–2 hours). Sand flush with 120-grit paper, then follow with 240-grit. Wipe off all dust with a damp cloth.
Step 3: Clean Walls with Sugar Soap
Mix sugar soap solution as directed and wipe down all walls from top to bottom. This removes grease, handprints, and any contaminants that would prevent paint adhesion. Rinse with clean water and allow walls to dry fully — at least 2 hours in a Melbourne autumn/winter environment.
Step 4: Prime Where Needed
You don’t always need a full primer coat, but prime in these situations: patched holes (spot-prime to prevent flashing); going from a dark colour to a light colour; new plasterboard or bare timber; stains (water marks, textas, nicotine) — use a stain-blocking primer like Zinsser BIN or Dulux Wash&Wear Prep.
Step 5: Mask and Cut In
Apply masking tape to all skirting boards, door frames, and window frames. Cut in (brush paint) along all edges first: ceiling line, corners, around power points and switches, at the top of skirting boards. Use an angled 50mm brush held at 45 degrees. Cut in about 50–75mm wide — enough that the roller won’t touch the trim.
Step 6: Roll the Walls
Load the roller by rolling it in the tray and rolling off excess on the ribbed part. Apply paint in a large W or M shape on the wall, then fill in without lifting the roller. Work in sections of about 1m wide from ceiling to floor, keeping a wet edge as you move along. Two coats are almost always required — allow the first coat to dry for 2–4 hours before applying the second.
Troubleshooting Common Painting Problems
| Problem | Cause | Fix |
|---|---|---|
| Roller marks or streaks when dry | Paint drying too fast; not enough wet blending | Lightly sand and apply another coat on a cooler day |
| Paint peeling or flaking | Surface not clean or primed; moisture in wall | Strip, find moisture source, prime with moisture-barrier primer |
| Brush marks in cut-in areas | Too much paint on brush; paint too thick | Less paint on brush, thin strokes; feather out before drying |
| Colour looks different to test pot | Lighting conditions differ; test pot was one coat | Full paint over two coats reads true colour in room lighting |
| Paint won’t cover old colour | Insufficient coats; high-LRV jump (dark to light) | Apply tinted undercoat or extra coat of colour |
Tips and Gotchas
- Buy 10% more paint than you think you’ll need. Running out mid-wall and needing a second batch risks a colour variation if the batch numbers differ.
- Low-sheen vs flat paint: low-sheen is washable and suits most rooms; flat/matte hides wall imperfections better but marks easily. Bedrooms often suit flat; living areas suit low-sheen.
- Don’t paint in temperatures under 10°C or over 35°C. Melbourne spring and autumn are ideal; mid-summer and mid-winter days with poor ventilation can cause adhesion and drying problems.
- Cheap rollers leave fluff in the paint. Pay for a Purdy or Wooster 9mm nap roller — it makes a visible difference in finish quality.
- Remove masking tape while paint is still slightly tacky, not bone dry. Removing dry tape can lift the fresh paint edge and require touch-up.
- Old Melbourne houses often have lead paint under multiple layers in pre-1970 homes. Don’t sand, scrape or torch without testing first. Lead paint test swabs are available at most hardware stores for around $20.
- Clean brushes and rollers immediately after use with warm water and detergent (water-based paint). A neglected brush is ruined within an hour in summer.
- Ventilate the room while painting and for several hours after — water-based paint VOCs can cause headaches in poorly ventilated rooms.

Frequently Asked Questions
How long does it take to paint a bedroom yourself?
A standard Melbourne bedroom (roughly 12–15m²) takes most people 4–6 hours for two coats including prep, cutting in, and rolling. Add an extra 1–2 hours if you’re painting the ceiling. Allow at least a day including drying time between coats.
Do I need to prime before painting?
Not always. If you’re painting the same colour over a clean, previously painted surface, a good quality paint (Dulux Wash&Wear, Haymes Prestige) can often cover in two coats without primer. Prime over bare plaster, patched areas, strong colour changes, or stains.
What paint finish should I use for a bedroom wall?
Flat or low-sheen for bedroom walls. Low-sheen is more washable; flat/matte hides surface imperfections better. Avoid semi-gloss on walls — it’s too shiny and shows every bump. Semi-gloss is for doors and trim only.
How much paint do I need for a standard bedroom?
A standard bedroom (approximately 12m² floor space) has about 40–50m² of paintable wall and ceiling area. A 10L tin of paint covers roughly 120m² per coat — so one 10L tin is enough for two coats of walls in most Melbourne bedrooms, with paint left over.
Final Thoughts
Painting a room yourself is one of the best-value DIY jobs in home maintenance — the materials are cheap, the skills are learnable with one practice wall, and the result is immediately visible. The biggest mistake is rushing prep: walls that aren’t clean, filled, and properly primed show every flaw under a fresh coat. Take the time to do it right, and a weekend’s work can transform a tired Melbourne bedroom for well under $200.
