Exterior Paint Selection Guide: For Turkey and Middle East Climates
How to choose the right exterior paint for the demanding climates of Gaziantep, Syria, Iraq and Jordan? Climate factors, product specs and expert recommendations.
Climate Factors Affecting Exterior Paint
Exterior paint selection is directly influenced by the climate conditions of the building's location. Wrong choices lead to premature fading, blistering and cracking.
Key climate factors: UV intensity, temperature differential (ΔT), relative humidity, dust/sand abrasion, freeze-thaw cycles.
Regional Climate Profiles and Product Recommendations
| Region | Annual Temp Range | UV Index | Humidity | Recommended System |
|---|---|---|---|---|
| Gaziantep | −5°C to +40°C | High (7–9) | Medium | Elastomeric acrylic |
| Syria (Interior) | −2°C to +42°C | Very high (8–10) | Low–Medium | UV-resistant acrylic |
| Iraq (Baghdad) | 0°C to +48°C | Very high (9–11) | Low | UV acrylic or silicate |
| Jordan (Amman) | 2°C to +38°C | High (7–9) | Low–Med | Elastomeric acrylic |
| Lebanon (Coast) | 8°C to +35°C | Medium–High | High | Anti-fungal acrylic |

Mold/algae resistance: Biocide-enhanced formulas for coastal/high-humidity regions.
Frequently Asked Questions
Can exterior paint be applied at 48°C in Iraq?
Ideal range is +8°C to +35°C. Above +35°C, paint dries too fast and brush marks appear. Schedule application early morning (7–10 AM) or evening (5–8 PM) in extreme heat.
How do I order MST paint for Syria or Iraq?
MST Boya is a Gaziantep-based manufacturer exporting to the Middle East region. Request a wholesale quote from our contact page.
How often should exterior paint be renewed?
In Gaziantep-like climates, quality exterior paint lasts 7–10 years. In extreme Middle Eastern UV and dust conditions, renewal every 5–8 years may be recommended.
