Amazon has a $2 off coupon on single 10oz tubes of Gorilla Waterproof Caulk and Seal. I keep at least one extra tube of white silicone caulk on hand for refreshing seals around bathtubs, sinks, and toilets. Keeping an extra on hand is also a good backup in case an open tube goes dry.

Applications for Silicone Caulk

White silicone caulk is a versatile and reliable product used in many home improvement and repair projects. Here are some of the most common applications:

• Sealing in Bathrooms and Kitchens:
  One of the main uses of white silicone caulk is to seal gaps around sinks, bathtubs, and showers. It creates a waterproof barrier that prevents water from seeping into cracks, which can help avoid costly water damage. Silicone caulk is mildew-resistant, making it perfect for damp areas like bathrooms.
• Around Windows and Doors:
  White silicone caulk is excellent for sealing around windows and doors to prevent drafts. By blocking air leaks, it helps regulate indoor temperatures, improving energy efficiency and lowering heating and cooling costs. This makes it a great option for weatherproofing your home.
• Plumbing Repairs:
  Silicone caulk is often used to seal around pipes in plumbing. Its flexibility and water resistance make it an ideal choice for preventing leaks and maintaining a strong, long-lasting seal in areas exposed to moisture.
• Filling Gaps and Cracks:
  If you have small gaps or cracks in walls, countertops, or even between tiles, white silicone caulk can be used to fill them. It remains flexible over time, which means it won't crack or shrink as some other materials might.

Silicone caulk's durability, flexibility, and resistance to water make it a popular choice for both small and large repair projects around the home.
