To apply a new waterproofing membrane on top of an old bitumen waterproofing membrane, the surface of the old membrane should be thoroughly cleaned and prepared. Any loose debris, dirt, or old adhesive should be removed to ensure proper adhesion of the new membrane. Once the surface is clean, a primer should be applied to promote adhesion between the old and new membranes. Finally, the new waterproofing membrane can be installed according to the manufacturer's instructions, ensuring that it is properly sealed and bonded to the old membrane to provide effective waterproofing. **

This serves as a reminder that even powerful Devil Fruit users have their limitations and can be defeated in battle. **

Ideally, the waterproofing membrane should be applied in dry weather to ensure proper adhesion and effectiveness. If the membrane is applied and then it rains before it has fully cured, it can compromise its ability to create a watertight seal. Water exposure during the curing process can lead to delamination, reduced adhesion, and potential leaks. Therefore, it is best to apply the waterproofing membrane when there is no rain in the forecast and allow it to fully cure before any water exposure. **
