Exterior paint serves a dual purpose: it beautifies and protects surfaces from the elements. However, over time, exposure to sun, rain, humidity, and pollution causes it to lose its shine and durability. Proper maintenance not only improves the appearance of the façade but also prevents major repair costs.
How often should you repaint?
On average, it is recommended to repaint the exterior every 5 to 7 years, although this period may vary depending on the type of paint, the quality of the product, and the weather conditions the house is exposed to. In very sunny or humid areas, the interval may be reduced to 3 or 4 years.
Signs that your paint needs maintenance
- Peeling or flaking paint.
- Appearance of moisture or mold stains.
- Loss of color or shine due to sun exposure.
- Cracks on painted surfaces.
Tips for effective maintenance
- Regular cleaning: wash the walls with water and neutral detergent to remove dust, mold, or stains.
- Prior repair: fill cracks, fix fissures, and remove damaged areas before applying a new coat of paint.
- Use of sealants and waterproofing products: they protect surfaces and extend the durability of the paint.
- Choosing the right paint: choose acrylic or elastomeric paints for exteriors, as they offer greater resistance to weathering.
- Professional application: specialized workmanship ensures a better finish and greater durability.
Benefits of good maintenance
- Extends the useful life of the paint and surfaces.
- Increases the aesthetic and property value of the house.
- Protects against moisture, mold, and structural damage.
