Completing the terrace and the balcony waterproofing of the buildings which will be exposed to water is important for the aesthetic properties and performance of a building.
You might have experienced problems related to a leaking balcony or a terrace after heavy rain. The downpour forms a pool in your balcony and it starts to leak down to the lower floor. The leaking from balconies is actually a serious problem. It can cause cracks and chips, not to mention the unsafe joints and sealants.
Just ceramic coating applied to the terraces and balconies of the building does not provide any protection without completing the waterproofing. There will be water leakage from the terraces to be constructed in this way, which will cause the lower floor comfort problem and reduce the life of the building.
Therefore, the selection and application of the right waterproofing material play an important role in terrace and balcony isolation. In this article, we will go through balcony waterproofing and the question of how do you waterproof an outdoor balcony.

It is necessary to prepare the application surface before applying the ceramic coating. Anti-sticking residues, loose parts should be cleaned before applying waterproofing materials. The surface should be smooth, firm, and clean. If required, surface defects should be repaired with suitable repair mortars.
To prevent the water from accumulating in the corners of the terrace and balcony to reach the lower layers, waterproofing should be provided by applying chamfer bands to the wall and floor junction points. Chamfer tapes, also known as waterproofing tapes, must be flexible to protect against possible expansions and maintain their elasticity.
Besides, high resistance to tearing is significant for terrace and balcony waterproofing efficiency.
After the surface preparation, the waterproofing layer application is started. At this point, it is critical to choose the most suitable waterproofing material in accordance with the water exposure of the building, its contact with the sun’s rays, and other needs.
After applying ceramic coating on the terrace and balcony surfaces, proper joint filling application and last layer protection material should be used. In the case of no coating, it will be important to choose a topcoat paint that is UV light resistant, non-fading, and resistant to pedestrian traffic.
