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. **

A utility knife or a sharp blade is typically used to cut the waterproofing membrane. It is important to use a sharp tool to ensure clean and precise cuts, which will help in achieving a proper seal and prevent water leakage. Care should be taken to avoid damaging the underlying surface while cutting the membrane. **

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. **

The term "new federal states" typically refers to regions or territories that have recently joined a federal system of government. On the other hand, "new federal states" could also refer to newly established states within a federal system. The distinction between the two depends on the context in which the term is used. **

The Federal Police (Bundespolizei) in Germany is responsible for border control, railway and aviation security, and other federal law enforcement duties. On the other hand, the Federal Criminal Police Office (Bundeskriminalamt or BKA) is the national investigative police agency, focusing on serious and organized crime, terrorism, and cybercrime. While the Federal Police has a broader range of responsibilities, the BKA is specifically focused on criminal investigations at the national level. **

In most federal states, secession is not allowed as it goes against the unity and integrity of the country. The constitution of the Federal Republic typically does not provide for the unilateral secession of a state. Any attempt to secede would likely be met with legal and political challenges, as well as potential opposition from the federal government. Ultimately, secession would require significant legal and constitutional changes to be achieved. **

No, the Federal President does not have the power to dismiss the Federal Chancellor in Germany. The Federal Chancellor can only be removed through a vote of no confidence in the Bundestag, the lower house of the German parliament. The Federal President's role is largely ceremonial and they do not have the authority to directly remove the Chancellor from office. **

In most federal states, the constitution does not explicitly provide for the right to secede from the federation. However, there have been historical instances where regions or states have sought to secede from a federal republic, such as the American Civil War. In most cases, the process of secession would require a constitutional amendment or negotiation with the federal government. Ultimately, the ability for a federal state to withdraw from the Federal Republic would depend on the specific legal and political circumstances of the country in question. **
