According to my experience using this industrial sealant, it effectively seals tub and wall gaps without hassle. The caulk strip is easy to install and it stays put for a long time without cracking or peeling... It also adheres well to DIFFERENT materials, making it a versatile option for many projects. However, it takes a bit of practice to master the installation process. Overall, i recommend this product for anyone looking for a reliable and durable sealant for their industrial and scientific projects..
