With temperatures regularly exceeding 45°C in summer and intense UV radiation year-round, choosing the right paint and calculating the correct quantity is critical for any UAE project. Underestimating leads to uneven coverage. Overestimating wastes money on expensive exterior-grade paint systems.
Our Paint Coverage Calculator gives accurate litre requirements for interior emulsion, exterior masonry, textured coatings, and epoxy floor systems with automatic door and window deductions.

🇦🇪 UAE Tip: For UAE exterior walls, always specify elastomeric or anti-carbonation paint with UV resistance and a minimum 10-year manufacturer warranty. Apply only when surface temperature is below 40°C — avoid painting between 10am and 4pm in UAE summer. New concrete and plasterwork must cure for minimum 28 days before painting.
The Formula Explained
Wall Area = 2 x (Length + Width) x Height. Net Area = Wall Area minus (Doors x 1.8m2) minus (Windows x 1.2m2). Litres = (Net Area / Coverage Rate per litre) x Number of Coats x 1.05 wastage factor.
Frequently Asked Questions
What paint is best for UAE exterior walls?
Elastomeric masonry paint with UV stabilisers. It bridges hairline cracks and resists extreme thermal expansion from UAE temperature swings. Jotun Majestic and Dulux Weathershield are widely available across UAE.
How many coats on new UAE plasterwork?
Three coats minimum on new plasterwork: one sealer coat, two finish coats. This gives uniform coverage and prevents alkali burn-through from fresh cement in the hot UAE climate.
What coverage rate for UAE exterior paint?
10 m2 per litre for standard exterior masonry paint. 8 m2 per litre for textured or heavy-duty coatings. Always check the paint data sheet for exact coverage at your specified dry film thickness.
