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. **

When using acrylic paint for painting, it is important to use pens that are specifically designed for use with acrylics. Some popular options include acrylic paint pens, acrylic markers, and acrylic ink pens. These pens are designed to be sealant-resistant, meaning they will not smudge or bleed when a sealant is applied over the painted surface. Look for pens that are labeled as waterproof, fade-resistant, and suitable for use on a variety of surfaces to ensure the best results for your acrylic painting projects. **

Yes, there are paint coatings that are resistant to acid but not resistant to alkali. These coatings are typically formulated with specific chemical compounds that provide acid resistance, but are not as effective against alkali substances. For example, epoxy-based coatings are known for their resistance to acids, but they may not perform as well when exposed to alkali solutions. It is important to consider the specific chemical resistance properties of a paint coating when selecting the right product for a particular application. **

The police mentioned in the question could refer to either the Brandenburg police or the Berlin police, as both are relevant to the context of the conversation. Brandenburg is a state in Germany, and Berlin is the capital city, so both police forces could be involved in the discussion depending on the specific circumstances being referred to. It would be helpful to provide more context or details in order to determine which police force is being referred to. **

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. **
