As an expert in the field of sealants and adhesives, I have extensive knowledge on the application and performance of various products, including Flex Seal. Flex Seal is a versatile rubberized coating that is designed to seal and protect a wide range of surfaces. It is known for its ability to create a watertight seal and is often used for a variety of applications, such as repairing leaks, sealing gaps, and even as a protective coating for various objects.

When considering the application of Flex Seal on a wet surface, it is important to understand the conditions that are most conducive to achieving the best results.
Flex Seal is formulated to bond to a variety of surfaces, including damp ones. However, it is crucial to note that the product will adhere better to a clean, dry surface. This is because moisture can interfere with the bonding process, potentially leading to a weaker seal.

If you choose to apply Flex Seal on a wet surface, there are several steps you should take to ensure the best possible outcome:


1. Assess the Surface: Before applying the product, it is essential to assess the surface. If the surface is slightly damp, it may still be possible to apply Flex Seal, but if it is excessively wet, it would be best to wait until the surface dries.


2. Clean the Surface: Regardless of whether the surface is wet or dry, it is important to clean it thoroughly. Remove any dirt, grease, or other contaminants that could prevent the sealant from adhering properly.


3. Apply Flex Seal: When applying Flex Seal to a wet surface, it is recommended to use the brush-on version of the product. This allows for better control and ensures that the sealant is applied evenly.


4. Allow to Dry: If the surface is wet or cold, Flex Seal will take longer to dry. It is important to allow sufficient drying time to ensure that the sealant has fully cured and formed a strong bond with the surface.


5. Reapply if Necessary: In some cases, it may be necessary to reapply Flex Seal to achieve the desired level of coverage and sealing.

It is also worth mentioning that Flex Seal is not recommended for use on surfaces that are constantly submerged in water or exposed to constant moisture, as this can affect the longevity and effectiveness of the seal.

In summary, while it is possible to apply Flex Seal on a wet surface, doing so on a clean, dry surface will yield better results. If the surface is wet, it is important to clean it thoroughly, allow it to dry as much as possible, and follow the manufacturer's instructions for application and drying times.
