Painting a ceiling yourself saves you €80 to €250 in decorator costs. Materials cost €20 to €60 for a standard room. Ceilings are trickier than walls – but with the right technique and paint you can achieve a streak-free result.
What Does Painting a Ceiling Cost? DIY vs. Decorator
| DIY (materials) | Decorator (materials + labour) | |
|---|---|---|
| Ceiling 15 m² | €20 – €60 | €100 – €250 |
| Ceiling 25 m² | €35 – €100 | €180 – €400 |
| With primer | €15 – €40 extra | Included |
Which Ceiling Paint to Choose?
Specialist Ceiling Paint (Matt, High Coverage)
- No light reflections – hides imperfections
- High coverage – often one coat is enough
- Low-spatter formula – fewer drips when working overhead
- Guide price: €15–€40 per 5 litres
Standard White Emulsion
- Less expensive
- Less coverage – often 2 coats needed
- Guide price: €10–€25 per 5 litres
Recommendation: Invest in a proper ceiling paint. The extra €5–€10 saves you a whole coat and greatly reduces spattering.
Calculating Paint Quantity
Formula: Ceiling area ÷ coverage per litre (on label) x number of coats
Example: 15 m² ceiling ÷ 8 m²/L x 2 coats = 3.75 litres → buy 4 litres
Materials List: Ceiling 25 m²
| Material | Quantity | Approx. Cost |
|---|---|---|
| White ceiling paint | 5–8 litres | €25 – €80 |
| Primer (if required) | 3 litres | €10 – €25 |
| Masking tape (25 mm, 25 m) | 4 rolls | €10 – €20 |
| Dust sheets | 30 m² | €8 – €15 |
| Roller sleeve (18 mm pile, for ceilings) | 2 pieces | €10 – €20 |
| Extension pole | 1 piece | €10 – €25 |
| Cutting-in brush (50 mm) | 1 piece | €8 – €15 |
| Paint tray | 1 piece | €5 – €10 |
Step-by-Step: Paint a Ceiling in 7 Steps
Step 1: Preparation
- Clear the room or move furniture to the centre and cover it
- Cover the entire floor with dust sheets
- Remove light fittings or at least the glass shade
- ALWAYS remove bulbs – water splashes on hot bulbs can cause breakage
- Mask sockets and switches
- Mask the junction between ceiling and walls
Step 2: Prepare the Ceiling
- Check for damage: cracks, flaking, water stains
- Fill cracks with filler and sand smooth
- Treat water stains with a stain-blocking primer (otherwise they bleed through)
- Apply stabilising primer to new or highly absorbent ceilings
Step 3: Apply Primer (If Required)
New plasterboard ceilings, highly absorbent surfaces or after repairs always need priming. Allow 2–4 hours to dry.
Step 4: Cut In
With a 50 mm brush, cut in a 5 cm strip around:
– Ceiling/wall junctions
– Around any ceiling rose or light opening
– Always keep a consistent width for clean edges
Step 5: Apply Paint with Roller
- Use an 18 mm pile roller sleeve – the longer pile hides imperfections
- Fit an extension pole – work from the floor, no ladder needed
- Apply in runs parallel to the window (light source)
- Overlap each run immediately into the wet edge of the previous one
- Work at a consistent pace – not too slow, not too fast
Step 6: Dry and Apply Second Coat
Allow at least 2–4 hours to dry (avoid draughts – uneven drying causes issues). Apply second coat with runs at 90° to the first coat.
Step 7: Remove Masking Tape and Tidy Up
Remove tape while paint is still slightly tacky – pull at a 45° angle.
Common Mistakes
| Mistake | Consequence | Solution |
|---|---|---|
| Short-pile roller | Streaks visible | Use 18 mm pile for ceilings |
| No extension pole | Uneven runs, neck strain | Always use an extension pole |
| Too thick a coat | Drips and lap marks | Two thin coats better than one thick |
| Not maintaining a wet edge | Drying marks visible | Always roll into the wet edge immediately |
| No side lighting | Misses thin spots | Use a work light from the side to check coverage |
FAQs
How do I prevent streaks when painting a ceiling?
Use the right roller (18 mm pile), work wet-in-wet, apply runs parallel to the window, use an extension pole and always roll the next run into the still-wet edge.
Do I need to paint two coats?
A quality ceiling paint over a white surface often covers in one coat. For colour changes, always apply two coats.
Do I need to prime?
New, absorbent or repaired ceilings: yes. Over well-adhered old paint: no.
