Outdoor furniture and salt air: what survives
In a coastal setting the materials that last are aluminium with anti corrosion treatment, teak, polyethylene fibre and marine grade stainless steel, while painted iron and softwoods degrade within a few seasons.

The short version
- Salt air carries strongly up to about 500 metres from the coast.
- Ultraviolet radiation degrades untreated fabrics in 2 or 3 seasons.
- Marine grade stainless steel resists corrosion better than standard grades.
- Storing cushions under cover multiplies their service life.
The enemy is not rain. It is the combination of sun and salt, and a cheap set looks splendid for one summer and unrecognisable by the third.
What each agent does
Ultraviolet radiation breaks polymer chains and degrades pigments, so fabrics lose colour and plastics turn brittle. Salt accelerates corrosion in metals and works its way into joints. And the night humidity, high on the island through much of the year, sustains a wet and dry cycle that punishes finishes and connections.
| Material | Resistance | Maintenance |
|---|---|---|
| Anodised or powder coated aluminium | very high | rinse with fresh water |
| Teak | very high | annual oil or let it silver |
| Polyethylene fibre | high | clean and check the weave |
| Marine grade stainless steel | high | clean and occasional polish |
| Standard stainless steel | medium | rust spots appear |
| Painted iron | low | frequent repainting |
| Treated softwood | low | treatment every season |
| Natural fibre | very low | under cover only |
The details that fail first
The screws. An aluminium piece with ordinary steel fixings develops rust spots in the first season and stains the frame. Then the cushion zips. Then the foot caps. Then glued joints in timber. When buying, look at those 4 points before the general finish, because they determine whether the set lasts 8 years or 3.
The fabrics
The weak point of any set. Solution dyed fabrics, where the pigment forms part of the fibre rather than sitting on top, hold their colour for many more seasons. Quick drying foams stop cushions holding moisture. And storing cushions in a box or under cover when not in use multiplies their life, even with good quality fabric.
A replacement set of covers costs 150 € to 500 €, far below replacing the whole suite.
The maintenance that changes things
A fresh water rinse every 2 or 3 weeks in season, which removes salt before it acts. Checking and tightening fixings once a year. Oiling teak every 12 months if the warm tone is wanted, or letting it silver, which is equally durable. And storing cushions and textiles out of season, between November and March.
Frequently asked
+Which material lasts best near the sea?
Treated aluminium, teak, polyethylene fibre and marine grade stainless steel.
+What fails first?
Ordinary steel fixings, cushion zips and glued timber joints.
+How often should it be cleaned?
A fresh water rinse every two or three weeks in season, to remove salt.
+Does teak need oiling?
Only to keep the warm tone. Letting it silver does not reduce its durability.
+And the cushions?
Solution dyed fabrics and quick drying foam, stored under cover when not in use.
