Pimples are caused by the overproduction of oil, clogged pores, and bacteria on the skin. When these factors come together, they can lead to inflammation and the formation of pimples. Coating on the tongue can be caused by a variety of factors, including poor oral hygiene, dehydration, smoking, and certain medical conditions. It can also be a result of the buildup of bacteria, dead cells, and food particles on the tongue's surface. **

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. **

Pimples are small inflammations of the skin caused by blocked pores or bacteria, while pox refers to a group of viral infections that cause skin lesions. Pimples are usually less severe and can be treated with over-the-counter products, while pox infections may require medical attention. It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment. **

Pimples and insect bites can often look similar, but there are some key differences. Pimples are usually caused by clogged pores and inflammation of the skin, while insect bites are typically caused by a bug or insect piercing the skin and injecting saliva or venom. Pimples may have a white or blackhead at the center, while insect bites may appear as red, swollen bumps with a puncture mark in the center. If you are unsure whether you have a pimple or a bite, it's best to consult a healthcare professional for an accurate diagnosis. **

Pimples themselves are not contagious. They are caused by a combination of factors such as excess oil production, bacteria, and inflammation in the skin. However, the bacteria that contribute to the development of pimples can be spread through direct contact, so it is possible to transfer these bacteria from one person to another. It's important to practice good hygiene, such as regularly washing your face and hands, to help prevent the spread of bacteria that can contribute to pimples. **

Vinegar can be both beneficial and harmful for pimples, depending on how it is used. While some people believe that vinegar's antibacterial properties can help reduce acne-causing bacteria and inflammation, others find that the acidity of vinegar can irritate the skin and worsen breakouts. It is important to dilute vinegar with water before applying it to the skin and to do a patch test to see how your skin reacts. Consulting with a dermatologist is recommended to determine if vinegar is a suitable treatment for your skin. **
