Flex Seal Spray is a great product for sealing out water, air, and moisture by providing a strong, flexible, and watertight seal. Whether used on running boards, a foundation wall, a motorcycle trailer or something else, Flex Seal Spray has proven to be effective. Some users have found it to be helpful in stopping water leakage due to cracks in their basement or fountain. However, while Flex Seal Spray is easy to apply, it can be messy, and it requires some preparation before use. For example, you need to tape off areas you do not want to apply the sealant to, and the nozzle casts a wide spray that needs to be passed over several times to ensure adequate coverage. Also, there is no texture to the material and it cannot be used as a masking liquid for windows. In terms of paintability, Flex Seal Spray comes in clear, so you can coat the gray or any of the 12 colors offered with a clear coating. However, the product's manufacturers do not recommend painting anything on Flex Seal Liquid products, as it can break down the seal. Overall, Flex Seal Spray is a decent product that offers an effective sealant. It has been widely used for several projects and found helpful.
