Yes, a watch that is water resistant to 3 bar means that it can withstand water pressure equivalent to a depth of 30 meters. This level of water resistance is suitable for everyday use, such as washing hands or light splashes, but it is not suitable for swimming, diving, or other water activities. It's important to note that water resistance can decrease over time, so it's recommended to have the watch tested for water resistance periodically. **

A wristwatch that is labeled as 5 bar water resistant means that it can withstand water pressure equivalent to a depth of 50 meters. This level of water resistance is suitable for everyday use, such as washing hands or being caught in the rain, but not for swimming or diving. It is important to note that water resistance can deteriorate over time, so it is recommended to have the watch retested for water resistance periodically. **

A wristwatch that is 5 bar water resistant means that it can withstand water pressure equivalent to a depth of 50 meters. This level of water resistance is suitable for everyday use, such as washing hands or being caught in the rain, but not for swimming or diving. It is important to note that water resistance can decrease over time due to wear and tear, so it is recommended to have the watch regularly checked and serviced by a professional. **

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. **

Yes, there is a standard for the silicone sealant used with wall-hung toilets. The sealant should be a high-quality, waterproof silicone sealant that is specifically designed for use in bathrooms and wet environments. It should also be compatible with the materials of the toilet and the wall, and be able to withstand the weight and movement of the toilet. It is important to follow the manufacturer's recommendations for the type of sealant to use in order to ensure a proper and secure installation. **

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. **

The Medusa piercing, also known as a philtrum piercing, is placed through the center of the upper lip, and it does have the potential to cut into the mucous membrane despite the use of a longer bar. The longer bar is meant to accommodate for swelling and provide room for movement, but if the piercing is not done properly or if the jewelry is not the right size, it can still cause irritation and damage to the mucous membrane. It is important to consult with a professional piercer and carefully follow aftercare instructions to minimize the risk of complications. **

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. **
