tiles

Tile coverings are the absolute classic, at least in the kitchen and bathroom. The ones made of stoneware are also for the balcony Tiles an alternative, which, however, has to be implemented correctly so that it is really weatherproof.

Balcony with tiled floor

Advantages:

  • very large selection of colours, structures, patterns and sizes
  • smooth surface can be cleaned quickly and easily
  • clear, modern look
  • durable

Disadvantages:

If floor tiles are laid with mortar or adhesive, these two auxiliary materials are a major weak point. Fine cracks form due to the weather, into which rainwater or running water penetrates. Adding frost to this will amplify the effect as freezing water expands. Even after professionally correct laying, sooner or later the covering will become brittle, brittle and flake off. Lay the tiles better on pedestals and pay attention to a gradient of at least. 2%, so that water can drain off quickly and completely.

Tip:

Do you like to be barefoot on the balcony in summer? Then tiles are not such a good idea, at least on a sunny balcony. Even if balcony tiles are still pleasantly cool in the morning, they heat up very quickly in the blazing sun.

natural stones

Natural stones are widely considered to be the most natural and beautiful covering for a balcony. But the durable covering is also one of the most expensive. The investment is therefore worthwhile if it is a home of your own, less so for rented objects.

Natural stone slabs stacked up

Advantages:

  • each natural stone is unique
  • ideal for a Mediterranean flair
  • Various natural colors available

Disadvantages:

  • limited choice of colors (vs. tiles)
  • must be laid on pedestals (otherwise frost damage)
  • have high weight
  • Stains are difficult to remove impregnate)

Tip:

Not every balcony can carry the same amount of weight. So before you rush to lay natural stones, you should first calculate their weight per square meter and with match the load capacity of the balcony.

natural stone carpet

For the natural stone carpet, gravel, often marble gravel, and a UV-resistant binder are mixed into a mass and spread evenly on the balcony floor.

Advantages:

  • is easy to apply, like screed
  • seamless balcony covering
  • offers stone look

Disadvantages:

  • good polyurethane-based binders are expensive
  • cheap epoxy resin (binder) yellows over time (not UV-resistant)
  • because stone carpet is not waterproof
  • Before laying, the subsurface must be sealed (frost protection)

Tip:

Laying a natural stone carpet requires a lot of professional skill and should better be left to professionals.

wooden floorboards

Wood is a widely available and sometimes cheapest material, from which attractive floorboards for the balcony can also be made. Considered durable Douglas fir floorboards and larch, as well as tropical wood (sustainably managed). In contrast, pine and spruce rot quickly and should be avoided for outdoor use.

  • easy-care

frequently asked Questions

Can I lay tiles with frost-resistant mortar and glue?

Even if these substances are frost-proof on their own, they should not be used for laying tiles on the balcony. Because the finished balcony covering then consists of several substances that show different expansion behavior in cold and heat, which inevitably leads to cracks.

Floorboards made of special thermal wood are offered, what is that?

Thermowood, also known as TMT for short, is wood, mostly beech and ash, that has been heat treated without chemical additives. After the treatment, the wood can no longer absorb as much moisture and becomes more resistant to wood-decomposing fungal attack. It also becomes harder and more dimensionally stable. The price for these benefits is increased brittleness under heavy loads.

Are planks made of WPC planks protected from weathering?

Even if WPC planks keep their appearance for a long time, they are not completely weatherproof either. This is also due to the plastic content, which is not resistant to UV light and is gradually decomposed by sunlight. This gradual weathering is reflected in the fact that the floor covering is becoming increasingly dull.
