Bathtubs are one of the most used fixtures in any home. They come in all shapes and sizes, and can be made from a variety of materials. No matter what your bathtub is made from, it’s important to keep it in good condition by using a sealant on a regular basis. Flex Seal is one of the best sealants on the market, and it’s perfect for sealing bathtubs. In this article, we’ll explain why Flex Seal is such a great choice for bathtub sealing, and we’ll provide instructions on how to use it properly.
Bathroom caulking can be a pain, but Flex Shot makes the job much simpler. This super thick rubber sealant doesn’t require a caulking gun; just push the nozzle for a perfect bead every time. Lots of customers have had success using Flex Shot in their bathrooms, and this is my top recommendation for bathrooms.
What is Flex Seal?
Flex Seal is a rubberized sealant that comes in a aerosol can. It can be used on a variety of surfaces, and it forms a watertight, airtight seal that is perfect for keeping out moisture. Flex Seal is great for sealing bathtubs because it prevents water from seeping through cracks and joints, and it also helps to prevent mold and mildew from growing.
What is caulking?
Caulking is a process of sealing cracks and joints with a flexible, watertight material. It is often used in bathrooms to seal around tubs, showers, sinks, and toilets. Caulking prevents water from seeping through cracks and joints, and it also helps to prevent mold and mildew from growing.
How to use Flex Seal in your bathroom
- Remove existing caulk: Use a utility knife or caulk remover to remove any existing caulking around your tub.
- Clean the surface: Use soap and water to clean the surface of your tub. Make sure the area is completely dry before proceeding.
- Apply Flex shot:
The Flex Shot features an extension tube that you can screw onto the end of the device, which is helpful for applying caulk in difficult-to-reach places. You can customize the length of Tube by cutting it to your preference: Cutting closer to the base will result in a thicker line whereas cutting towards the tip will create a thinner line.
Apply Flex Shot to the areas you are caulking by pressing down on the nozzle. To preserve Flex Shot, after use dispense a small amount out of the end of the tube before replacing the cap. This will form a plug and help prevent drying. When you want to re-use it, simply remove the plug prior to using again.
4.Smoothen the surface:
Use a wet finger or a damp cloth to smoothen the surface of the Flex Shot.
5.Allow it to dry: Allow the Flex Shot to dry for 24 hours before using your tub.
