This is how exterior paints for façades in coastal areas should be.
Although owning a home on the coast is a dream for many people, today we are here to remind you that not everything is as rosy as it seems (and never better said).
Well, actually it is, but we would also like to remind you that homes located in sunny coastal areas – such as Mallorca – require certain care as, among other things, a special exterior paint that protects their façades and contributes to their conservation.
In places such as the Balearic Islands, which are particularly sunny and close to the sea, buildings are constantly exposed to a combination of aggressive agents that accelerate the deterioration of exterior coatings. Intense solar radiation, high humidity, salinity carried by the sea air and daily temperature changes create a particularly vulnerable environment for any painting system.
For this reason, choosing conventional exterior paints for façades is not enough: it is essential to opt for products specifically formulated to withstand this environment and protect the exterior of homes for longer.
The influence of the coastal environment on façades
The marine environment has a silent but persistent effect on building materials, making it a much worse enemy than it might seem.
On the one hand, the salt present in suspension is deposited on surfaces and promotes chemical degradation processes, while the constant humidity that accompanies it can penetrate the pores of the walls, causing flaking, blistering or the appearance of microorganisms such as algae and fungi.
Added to this is the strong incidence of ultraviolet rays, which degrade the pigments and resins in the paint, causing loss of colour, cracking and reduced elasticity.
In this context, unsuitable paint can not only lose its aesthetic function in a short time, but also leave the façade exposed to more serious structural damage.
Characteristics of exterior paints for coastal façades
To offer effective and long-lasting protection, exterior paints for façades located in coastal environments must meet a series of very specific technical requirements:
- High resistance to UV radiation to prevent premature degradation of the colour and protective film.
- Impermeability to rainwater, preventing moisture absorption but maintaining the breathability of the substrate to allow water vapour to escape.
- Protection against salinity using high-quality resins that are not affected by the chlorides present in the marine environment.
- Elasticity and adaptability, essential for absorbing the expansion and contraction of the substrate caused by thermal changes.
- Anti-mould and anti-algae properties, essential in areas with high environmental humidity to keep the façade clean and healthy.
Durability, aesthetics and long-term protection
In addition to their technical characteristics, exterior paints for façades in coastal areas must guarantee colour stability and a uniform finish for years to come in order to reduce the frequency of repainting and prolong the life of the façade.
In environments such as the Balearic Islands, where the climate is part of the appeal of the landscape but also a challenge for building, choosing the right exterior paint is not just a question of aesthetics, but a key decision for the conservation and value of the property.
At gHouse, we not only pay meticulous attention to the construction materials, but also to the paints and varnishes we use in the final stage of the project, always ensuring that the exterior paints for façades protect these surfaces and help them look their best for longer.
