ᐅ Which wooden decking is best for a balcony floor? Considering “lightweight granite slabs” instead.

Hello.
I have a rather unattractive balcony floor. According to the specifications, it is called a "light granite slab."
It looks like hospital flooring and also feels very thin and unstable.

I want to install a wooden floor over this surface.
Either planks or click-together tiles.

Can anyone provide advice?
The balcony faces south and is not covered.
It gets strong sunlight, and in winter, snow lies on it.

Thank you

Flooring like in hospitals, and at least seemingly very thin, sounds a bit like linoleum.
Linoleum is not necessarily a bad choice.
But that’s not really the main point here.

Wooden planks or tiles
You probably cannot lay tiles without first removing the existing unknown floor. I’m not familiar with click tiles, so that should be mentioned, but given the small area, I imagine it wouldn’t be easy without preparation.
Tiles are very cold in the shade and during transitional seasons.
When exposed to sunlight, they can also become very warm to hot, making it uncomfortable to stand on barefoot.
For me, tiles would therefore be the second choice.

Wooden planks. Basically, there are many types of wood to choose from, with various impregnation options available. There are also many color possibilities.
Some planks are fully impregnated, meaning they are not just coated on the surface but impregnated throughout. This could be interesting for a snow-covered area.
I don’t have personal experience with this, but I’ve heard the protection can be so durable that the wood is practically "indestructible."
This would also mean no graying or silvering, in other words, color-stable.
You would need to research what exactly this entails yourself.
Otherwise, larch is probably a good choice—definitely a durable wood for outdoor use.
Bamboo could also be an interesting option here.
Most likely, the current floor wouldn’t necessarily have to be removed if you go with wood, depending on the situation, for example, the build-up height at the terrace door.
Since weather conditions are generally harsh on your balcony, if strong impregnations are not suitable, possible, or desired, I would rather choose a slightly darker shade. A lighter color will probably become unattractive quite quickly.
