ESTIMATION NOTICE

This calculator provides APPROXIMATE QUANTITIES for budgeting and planning purposes.

Please note:

• Results include standard wastage factors but actual waste may vary based on site conditions, workmanship, and material quality.

About This Calculator

The Paint Area Calculator helps contractors and quantity surveyors estimate paint and primer requirements for interior and exterior surfaces across UAE and Gulf construction projects. Calculate wall areas, deduct openings, determine coverage per gallon/liter, and account for multiple coats. Essential for fit-out pricing and material procurement planning.

When to Use This Calculator

  • Estimating paint quantities for tender submissions
  • Planning material procurement for fit-out projects
  • Calculating costs for residential and commercial painting
  • Comparing paint options based on coverage and price
  • Verifying subcontractor material claims

How to Use This Calculator

1

Enter Wall Dimensions

Input wall heights and lengths, or total wall area if known.

2

Deduct Openings

Enter door and window quantities/sizes to subtract from paintable area.

3

Select Paint Type

Choose interior/exterior, finish type (matt, silk, gloss) affecting coverage rates.

4

Set Number of Coats

Specify coats required (typically 2-3 for new surfaces, 1-2 for repaints).

5

Review Results

Get paint quantity in liters/gallons, primer needs, and material cost estimate.

Typical Scenarios in UAE & Gulf Projects

Villa Fit-Out in Dubai Hills

Finishing contractor estimates paint for a 4-bedroom villa (380m² wall area after openings). Using Jotun Majestic Silk at 12m²/L coverage, 2 coats required: 63.3L paint + 15L primer for new plaster. Calculator adds 10% wastage = 70L paint, 17L primer for procurement.

Office Building Repaint in Abu Dhabi

Facilities manager calculates repaint requirements for 2,500m² office. Existing painted surfaces need 1 coat only at 14m²/L coverage. Calculator determines 180L paint, no primer needed, with 5% wastage factor for touch-ups.

Frequently Asked Questions

Typical coverage rates: Premium emulsion 10-12 m²/L, Standard emulsion 12-14 m²/L, Exterior paint 8-10 m²/L, Primer/sealer 8-10 m²/L, Textured paint 4-6 m²/L. Rates vary by surface porosity (new plaster absorbs more), application method, and color (dark colors may need extra coats).

New plastered walls: 1 coat primer + 2 coats paint minimum. Repaint over existing: 1-2 coats (no primer unless changing from dark to light). Exterior: 1 primer + 2-3 coats for UAE climate durability. Ceilings typically 2 coats flat white.

Yes, add 5-10% wastage for: Roller/brush absorption, Uneven surfaces, Touch-ups, Color matching between batches. Add 15-20% for textured finishes or spray application. Professional painters typically achieve 5% wastage; DIY/unskilled may be 15-20%.
