Interior painting is an investment in the aesthetics and protection of your home in Coimbra or Aveiro. But how long can we expect it to last before needing a refresh? The answer isn't straightforward, as it depends on several factors. On average, quality paint can last between 5 to 10 years, but with the right care and professional execution, this timeframe can be significantly extended.
To maximise the durability of your paint, it's crucial to consider the environment. High-traffic areas, such as hallways and kitchens, tend to wear out more quickly. Direct sun exposure, humidity, and even the presence of pets or small children can accelerate the process. Opt for washable paints in high-use areas and ensure adequate ventilation in spaces like bathrooms to prevent mould growth and premature degradation of the painted surface.
However, the true key to paint longevity lies in preparation and professional expertise. What seems like a simple act of painting is, in reality, a complex process that begins long before the first coat. Casa Renova invests 70% of its working time in meticulous preparation: substrate diagnosis, moisture treatment, crack repair, stripping, sanding, and the application of filler and primer. Without this solid foundation, the paint, even with the most expensive paints, can crack in the first winter. We use professional materials, such as airless systems and sanders with extraction, which guarantee a superior and durable finish, something unattainable with domestic tools. Furthermore, access to high-quality paints and coatings, which are not found in retail stores, and in-depth knowledge of the right product for each substrate, correct dosage, and adherence to drying times, are crucial. It is this craftsmanship, this attention to detail and technique, that differentiates paint that lasts for years from paint that degrades in months, whether it's wall paint, marmorino, limewash, or Venetian stucco. We also master the application of wallpaper, polished concrete, and the renovation of metalwork and metal shutters.

At Casa Renova, we use high-quality professional paints, from ranges designed specifically for trade applicators and building professionals. These are not ordinary retail paints from a DIY store: they are chosen for their performance, covering power, ease of application and durability over time.
But materials are only half the job. What makes paintwork last is what you cannot see: assessing the substrate, preparing the surfaces, repairing cracks, applying the right number of coats and respecting drying times. That craft is what separates a wall that looks good for a month from one that looks good for ten years.
Every project is prepared, carried out and checked by professionals who do this every day. Because a quality renovation starts with choosing the right products and ends in the care taken during the work, we make no compromise — neither on materials nor on method.
