Magpipintura ng bedroom? Bago bumili ng pintura, sagutin muna ang tatlong tanong: Ilang square meters ang walls? Ilang coats? At anong kondisyon ng pader? Kapag mali ang isa, puwedeng kulang ang pintura—o sayang ang budget.
Quick answer · Sample 3 m × 4 m bedroom
33.8 m² estimated paintable wall area
Two coats = 67.6 m²-coats. Your paint quantity depends on the actual coverage printed for your chosen coating. For illustration, at 10 m²/L per coat, the calculation is 6.76 L before allowance. This rate is an example, not a Boysen product specification.
01 / Measure first. Don’t guess by room size.
Measure the length, width and height of your room. For a rectangular bedroom, the gross wall area is 2 × (length + width) × height. Measure ceilings separately if they are part of your project.
Worked example: 3 m × 4 m bedroom, 2.7 m ceiling
| Wall perimeter | 2 × (3 + 4) = 14 m |
| Gross wall area | 14 × 2.7 = 37.8 m² |
| Example door + window openings | − 4.0 m² |
| Estimated paintable wall area | 33.8 m² |
Your own doors, windows, alcoves, and wall shapes will vary. Allow for edges, touch-ups, and sensible waste.
02 / Calculate paint using the actual label.
Formula: liters = (paintable wall area × recommended coats) ÷ stated coverage per liter per coat. Use the manufacturer’s coverage information for the exact finish and substrate, and calculate primer separately when required.
For a new wall or a dramatic color change, coverage may differ from a sound previously painted surface. Porosity, texture, application method and coat thickness all matter. A quoted paint quantity should reflect these conditions rather than pretending every wall is identical.
03 / Diagnose the wall before choosing the coating.
Peeling or powdery? Remove loose coatings, clean and assess whether an appropriate primer is needed.
Stains or moisture? Trace and repair the source first. Painting over ongoing dampness is not a lasting fix.
Holes or cracks? Repair with compatible materials; check curing and primer recommendations before finishing.
Previously painted and sound? Clean, prepare, and check the compatibility of the new paint system.
04 / Assemble only the supplies your job requires.
Broad walls may call for a compatible roller, while a paint brush helps around corners, trim and edges. Use suitable masking tape to protect edges where appropriate, plus drop sheets, a tray and safe access equipment. Check the chosen paint’s technical guidance for tool compatibility.
If you’re considering a Boysen finish, start by choosing the correct color and painting system—not by choosing an arbitrary base can. Custom-mixed colors may need a confirmed quotation and the correct available pack sizes.
05 / Your bedroom painting checklist
Save this simple sequence before buying anything:
- Record room length, width and wall height.
- List all wall and ceiling surfaces you intend to paint.
- Subtract major windows and doors reasonably.
- Check the coverage and number of coats for the actual Boysen paint or selected coating.
- Inspect for dampness, peeling, cracks or chalking before painting.
- Plan compatible primer and repair materials only if needed.
- Choose a suitable roller, paint brush, masking tape and surface protection.
- Confirm the exact color, finish, pack sizes and quotation before ordering.
Common questions
Will one 4-liter can cover my bedroom?
Not always. It depends on the actual wall area, coating coverage, coat count and surface condition. Calculate first and allow for reasonable touch-ups.
Do I need primer?
That depends on the substrate and the chosen painting system. Previously painted sound surfaces, porous new plaster and problem surfaces may require different preparation.
Can I repaint over a damp patch?
First fix the source of the moisture and ensure the wall is ready under the coating manufacturer’s instructions.
