Maintain and oil wooden terrace

It's the same with wood as with people: gray comes with age. Decking boards outdoors lose their natural wood color through sun and rain and acquire a silver-grey patina. In addition, surface cracks appear over the years. This process can be slowed down by oiling, but not stopped completely.

How will my wooden terrace age?

The color of the wood changes when exposed to the weather. Jatoba and Garapa initially darken significantly in sunlight before turning grey, while teak quickly turns silver. Therefore, you should not base your choice of wood species solely on the colour, but always keep an eye on the aging process.

Cracks on the decking boards

Cracks on the surface or at the ends also appear on decking boards. Although this effect is more pronounced in domestic woods, it also occurs regularly in tropical woods.

The right care products

From a technical point of view, the graying of the terrace and the formation of cracks is not really a problem: it does not reduce the durability of the wood. However, unsightly dots and stains can form, which can be easily removed with the right care. Cleaning and impregnation can also extend the natural lifespan of the decking. What is the right care for your wooden terrace depends above all on what the aim of the care should be. Here you will find an overview of the suitable products for terrace care.
