The larger the parasol, the more protective shade it offers. However, the question of the appropriate size depends on the space you have available on your balcony, terrace or in your garden.
Round models with a diameter of 150 to 200 centimetres are suitable for small balconies.
If you have a lot of space outside and are looking for an umbrella that will provide you, your family and your friends with sufficient shade even when you are eating together, you are well advised to choose a square umbrella. Square and rectangular models are available in many different sizes. Before ordering, it is best to measure with the help of a folding rule which area the umbrella should ideally cover.

Not all textiles automatically offer protection against harmful UV radiation. You should choose an umbrella that complies with the UV standard 801. With these you can be sure that their protective effect has been tested.
The UV Standard 801 label indicates the exact UV protection level (UPF) - levels 10, 15, 20, 30, 40, 60 and 80 can be achieved. The respective class is the multiplier of your skin's own protection time. If you like to spend entire days in your garden or on your balcony, the UPF of your umbrella should ideally be 80. Below this level, the self-protection time of your skin increases by a factor of 80.

Yes, you can also get a tan under a parasol. UVA and UVB rays are refracted by various factors on their way. As a result, they don't just hit us perpendicularly. The refracted rays, the so-called global radiation, also run horizontally.
Accordingly, you will also get a tan under a sunshade. On long days in the sun, you should still rub a sunscreen on your skin.

A firm anchoring of the parasol on the balcony is not possible. With a parasol stand filled with sand or water, you can still ensure that your balcony parasol is sufficiently stable.
Particularly practical, especially if you don't have a lot of space on your balcony, are parasol holders that you can attach either to the parapet or the railing.
Another option is to attach it to the wall of the house. However, you will have to drill into the façade - you will need your landlord's permission.

Beach umbrellas are put directly into the sand. It is easy to make the umbrella hold somehow. However, a little trick is needed to ensure that the umbrella doesn't fly up and away at the first gust of wind.
With a little water and sand, you can easily pour your own foundation. To do this, dig a hole with a small shovel and fill it with damp sand, which you fetch from the shallow water on the shore with a bucket. If you now put the umbrella into the hole filled with silt, it will hold tightly.

The most effective way is to use ground sockets. You insert them into the ground and additionally fix them with concrete. It is almost impossible for the parasol to blow away with this mounting.
This method is only suitable if you always set up the umbrella in the same place. It is also not feasible on the balcony.
Umbrella stands that are additionally weighted down with plates are flexible and stable at the same time. On the balcony, I recommend that you also tie the umbrella to the railing.

Dust and small branches and leaves can be removed by gently brushing the opened parasol.
If a bird drops something while flying over it or if rotten, muddy fruit lands on the parasol, you should act quickly. Dampen the area as soon as possible and remove the stain with warm water and a soft sponge. Only use a gentle detergent if absolutely necessary.
If the upholstery is stubbornly dirty, you will have to go to extremes. The cover of some umbrellas can be cleaned in the washing machine. Of course, the drum must have sufficient capacity for the cover. Another option is to clean with a pressure washer. Choose the gentlest jet possible.
