The best exterior facade finishes to withstand the sun and sea salt

Living by the sea, whether in the Alpes-Maritimes or the Var, exposes your facades to two formidable enemies: the intense sun and the air loaded with sea salt. To ensure the longevity of your home while maintaining a beautiful aesthetic, choose the right exterior finishes will be required. Various solutions exist to ensure maintenance seafront facade efficient, offering excellent UV/sun resistance, but also optimum sealing against marine sprays. Between technical paint, innovative slate and suitable wood processing, let's see together the most efficient options.

What criteria of choice for a resistant exterior finish?

Before selecting a external finish, the local climatic conditions. The proximity of the sea implies a permanent exposure to marine salt, which gradually attacks materials and reduces their lifetime. To this is added the action of UV rays, particularly aggressive on the French Riviera, able to quickly tarnish colors or crack supports.

A good finish must combine several qualities: salt resistance, UV protection, and ability to let the holder breathe. To determine precisely what material for a durable facade suitable for your project, it is essential to take into account the specific exposure of your building.

Front painting: what solutions should be preferred by the sea?

The choice of facade paint represents a key issue to combine aesthetics and protection. There are now technical ranges specifically formulated for coastal areas. Two families of paintings dominate the market thanks to their performance in a salty and sunny environment: Siloxane paint and pliolite paint.

What is a Siloxane painting and why adopt it?

Siloxane paint incorporates silica resins that give great impermeability. Its major asset remains its strong UV resistance. It is also relevant to learn about the installation of a waterproof coating for facade to strengthen the barrier against saline moisture before applying decorative finishes.

In addition, its slightly satin surface prevents dirt and foam from hanging. It is therefore one of the marine finishes for the Mediterranean coast, where maintenance must remain minimal and longevity guaranteed despite a demanding climate. It is also interesting to look at practical advice on the best use of Siloxane paint and coating according to the type of facade in order to choose the most suitable solution for each coastal environment.

When would you prefer a pliolite painting for its facade?

Fliolite paint is renowned for its excellent adhesion on ancient backgrounds. Its optimal penetration guarantees a very good hold, especially in a windy situation. To obtain a sustainable rendering and avoid the classic traps, do not hesitate to follow our decoration tips painting before starting your project.

Its fine application promotesWaterproof walls while forming a solid barrier against infiltration. Although less microporous than Siloxane, Fliolite also offers a beautiful UV resistance and preserves its original hues for a long time.

External cladding: composite or exotic wood for the coastline?

For those who wish to associate modernity and heat of a natural material, the external slatting is a highly appreciated solution along the coastline. But not all slates are equal to the sun and marine salt.

Two main categories draw their pin from the game: the composite slatting, designed from a mixture of highly resistant fibres and resins, and exotic wood slatting from sustainably managed and naturally imputable forests.

How does a composite slate work in the marine environment?

The Composite slatting new generation are designed to imitate the appearance of wood without heavy maintenance constraints. Their dense structure, reinforced by specific additives, gives them a resistance to sea salt and an insensitivity to discoloration due to UV.

Their benefits include:

• One shock protection effective against wind-borne projectiles
• Zero risk of moulding or deformation under the effect of thesalty humidity
• Stable and varied colours, adapted to each local architectural style

A simple cleaning usually suffices to keep their Initial aspect.

Why opt for exotic wood and how to maintain it?

The exotic wood slatting pleases for its natural elegance and authenticity. Teck, ipé or padouk are among the species popular on the coast, because they do not fear moisture, resist well to the marine salt and have a high density limiting fungal attacks.

The secret to preserve these species lies in the wood processing, coupled with regular use of a wood saturator. This product nourishes the fibres and protects the appearance of the wood without masking its veining.

Sealing and overall performance of the facade system

Whether painted or barred, a facade in coastal zone calls for special attention to be paid tosealing. Infiltrationsalt water can cause severe structural pathologies if the envelope is not properly protected. Opt for a marine quality finish protects the frame, reduces maintenance costs and optimizes the life of your investment.

It is also recommended that adapted accessories : flexible joints, stainless rain-shield grilles, anti-corrosion fixings and horns specially designed to withstand in a salty atmosphere ensure the cohesion and longevity of the entire system.

• Regular state control paintings and wood processing
• Rapid replacement of oxidation-prone elements
• Freshwater cleaning to limit salt deposits

Preventive and targeted interventions make all the difference over the long term.
