Exterior paint is engineered to withstand direct sunlight, rain, dust, and salt air, with flexible binders that resist cracking and peeling. Interior paint is made for enclosed rooms and has lower weather resistance. For projects in Riyadh or Jeddah, check UV protection, humidity tolerance, and the recommended number of coats.
Lifespan depends on paint type, surface preparation, number of coats, and daily heat shifts. Quality exterior systems can last five to ten years before repainting in areas like Dammam or Khobar. If a wall faces strong sun, choose a high-UV formulation with a proper primer to protect color and adhesion.
Yes. Exterior walls need a suitable primer or patching layer to fill gaps, seal porous surfaces, and improve adhesion, especially on new plaster or cracked walls. Usually, apply one primer coat followed by two exterior paint coats for even coverage. Allow the recommended drying time between coats to prevent peeling.
Coverage varies by paint type, viscosity, and wall porosity. Most exterior paints use about 200 to 300 milliliters per square meter per coat, but rough, unsealed, or heavily textured walls may consume more. When buying from Matkel, use the data on the container or ask the consultation team to calculate the exact quantity for your project.
Matkel exterior paints are designed for high heat, humidity, and moderate rainfall, with resistance to cracking and peeling when applied correctly. In coastal areas such as Jeddah or Jubail, choose a salt-resistant and humidity-tolerant system, use a quality primer, and apply two finish coats with proper drying intervals.
