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. **

South Tyrol is the correct spelling for the region in northern Italy. It is an autonomous province with a majority German-speaking population. The region is known for its stunning alpine landscapes, charming villages, and a unique blend of Austrian and Italian cultures. **

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. **

South American countries are located in the southern part of the American continent and include countries such as Brazil, Argentina, Colombia, Peru, and Chile.

It is difficult to predict whether South Korea would unify Korea under its government as it would depend on various factors such as the political climate, international relations, and the will of the Korean people. South Korea has expressed its desire for peaceful reunification in the past, but the process would likely be complex and require careful negotiation with North Korea and other involved parties. Ultimately, the decision to unify Korea under the South Korean government would be a result of diplomatic efforts and the willingness of all parties involved to work towards a peaceful resolution. **

South Tyrol is a region in northern Italy with a unique cultural and linguistic identity. While there have been calls for greater autonomy or even independence from some groups within South Tyrol, it is unlikely that the region will become an independent country again. The region is currently part of Italy and any changes to its status would require significant political negotiations and agreements between the Italian government and the local authorities. **

The question of whether the south is better is subjective and depends on individual preferences. Some people may prefer the warmer climate, slower pace of life, and southern hospitality found in the south. Others may prefer the amenities, cultural diversity, and opportunities available in other regions. Ultimately, the idea of what is "better" is relative and varies from person to person. **
