The biggest challenge for joints in wet rooms is that water and soap residue can form a breeding ground for bacterial growth that breaks down the joint and gives it a reduced lifespan. Therefore, wet room jointing primarily requires a resistant joint compound.
In addition, you can reduce the risk of unnecessary wear and tear on the wet room joints by minimizing the number of horizontal joints. This makes it much more difficult for water, soap residue and dirt to settle on the joint, thus extending the life of the joint. In addition, the home owner can ensure that the joints are not exposed to unnecessary stress and thus last longer by regular drying and cleaning, as well as good ventilation in the room.
