Recurring leaks no longer disrupt your home
Seal leaks across common surfaces — clear, flexible spray-on coating, weather-resistant, touch-dry in 12 hours.
Why Is This Leak Protection Perfect for You?
✔ Weather-resistant protection: The clear, flexible coating adheres firmly while preserving the original appearance of the surface. It withstands rain, wind, moisture, cold, and sunlight to help protect sealed areas from leaks.
✔ Touch-dry in 12 hours: The coating becomes touch-dry in 12 hours, so the repaired area can be used again soon. It fully cures in 24–48 hours to form a waterproof seal.
✔ Suitable for multiple surfaces: Apply the spray-on coating to seal leaks on roofs, pipes, windowsills, toilets, and other surfaces. Clean the surface and shake the can before application; no specialized experience is required.
