Cautionary notes for balcony waterproofing include:

First and foremost in balcony renovation, consider waterproofing the floor, ensuring a slight slope during the process. Additionally, maintain a height difference of at least 2 to 3 centimeters between the balcony and the living room. The house itself has a natural height difference of about 1 centimeter, which can be enhanced by laying a marble slab for both practicality and aesthetics.

Sliding Door Waterproofing
Due to the abundant rainfall in the south, many homeowners install sliding doors on their balconies. The chosen sliding doors must ensure quality and good sealing to achieve the waterproof effect.

Wall waterproofing height
The waterproofing height of the balcony wall should typically be no less than 30 centimeters. If a washing machine is present, the waterproofing should be extended higher. For an exposed balcony, it's preferable to waterproof the entire wall. As for thickness, the waterproof coating must reach 1.5 millimeters.
