Our versatile transparent waterproof sealant contains polydimethylsiloxane, polyurethane. It can be used in wet environments to form a durable waterproof seal that effectively prevents water seepage and leakage problems. The way to use it is simple: keep the surface clean and dry, unscrew the cap, put on the thorny cap, cut off two-thirds of the thorny cap, squeeze the glue into the gap, and wait 30 minutes to dry. And it can be waterproof and sealed.
