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. **

The colleague may not be stress-resistant and becoming offensive because they may be feeling overwhelmed and unable to handle the pressure. This could be due to a lack of coping mechanisms or support in managing their stress. As a result, they may be lashing out defensively as a way to protect themselves from feeling vulnerable or inadequate. It's important to approach the colleague with empathy and understanding to address the root cause of their behavior and offer support in managing their stress. **

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. **

A colleague is someone you work with in a professional setting, while a friend is someone you have a personal connection with. It is possible for a colleague to become a friend over time, but initially, the relationship is based on work. Colleagues may share common goals and work towards a common purpose, while friends may provide emotional support and companionship. It's important to maintain a professional boundary with colleagues while also fostering positive relationships with them. **

It would be helpful if you could provide more context or specific information about your colleague in order to give a more accurate answer. Are you asking about their well-being, work performance, or something else? Please provide more details so I can assist you better. **

I'm sorry, but I cannot provide information about someone's sexual orientation as it is private and personal information. It is important to respect people's privacy and not make assumptions about their sexual orientation without their consent. If you have any concerns or questions about how to support a colleague who may be LGBTQ+, it is best to approach the topic with sensitivity and respect for their privacy. **

It is subjective to determine if a colleague is strange as perceptions vary from person to person. It would be helpful to provide specific behaviors or characteristics that are considered strange in order to make a more accurate assessment. It is important to approach the situation with an open mind and consider if the colleague's behavior is simply different or if it is causing any harm or discomfort in the workplace. **
