Choosing Interior Paint for Coastal Humidity in Lebanon

Coastal apartments in Beirut, Jounieh, Tyre and Tripoli battle persistent moisture; mountain homes in Aley and Bhamdoun deal with condensation when winter heating meets cold exterior walls. The paint and the prep are at least as important as the colour.

Spec your system

1. Surface prep. Treat any existing mould with a fungicidal wash (the chlorine-based product the paint store will recommend), let it dry fully, scrape loose paint, fill cracks.
2. Primer. Use an anti-mould primer on bathrooms, kitchens, and any exterior-facing wall. On previously painted walls in bad shape, consider a sealing alkyd primer.
3. Topcoat. Two coats minimum. For humid rooms choose a paint marketed as anti-mould and washable.
4. Sheen. Matt hides imperfections but holds dirt; eggshell or satin in kitchens / bathrooms / hallways is wipeable. High-gloss for trim only.

Brand vs. tinting machine vs. local mix

Branded paint (Lebanese: Tinol, Sipes, Carbon; international: Jotun, Sigma) with a tinting machine guarantees a repeatable colour batch — essential if you may need to touch up. Loose mixes from small stores are cheaper but rarely match later.

Ventilation matters more than paint

• Open windows 10–15 minutes a day in winter even when heating.
• Leave 5 cm gap between large furniture and exterior walls — closed-off air pockets are where mould always starts.
• Install a small extractor or dehumidifier in chronically damp bathrooms.

Coverage & cost

One litre of standard interior paint covers about 10 m² per coat. A 100 m² apartment (≈ 250 m² of walls + ceilings) typically uses 25–35 L per coat. Labour in Beirut runs 4–8 USD/m² for a quality job, more for ornate plaster ceilings.
