My balcony is sealed, as an indoor balcony, is it okay not to apply tiles and paint exterior walls?

You can choose water-based exterior wall paint, and it is OK to choose water-based paint to minimize harmful substances.

You can complain to the property about this, if the neighbor decoration occupies the place of your home or causes obvious inconvenience, it is an illegal construction. Its demolition can be claimed.

This is unreasonable, first of all, the reason for the water leakage downstairs is caused by the installation of balcony piling holes, in fact, they seal the balcony technology is not at home, and the waterproofing is not handled well, so how can you be responsible. Because it's right for them to find a balcony.

Then you can ask the property why other people's homes don't let you seal it, and you must give you an explanation. Otherwise you can complain about him. Personally, I think that other families may give gifts to the property, and if you don't give it, you won't let you seal it.

You are in charge of your own house. Nothing is forbidden by law!
