- When properly installing drywall or like-surfaces above a
- shower base or bathtub, the 1/4″ gap between the top of
- the tile flange and finished wall should be carefully sealed
- with a high grade silicone sealant. Unfortunately, drywall
- installers fail to make that seal in most installations.
- Mustee?s patent-pending GapSeal-Pro? tile flange seal
- solves that problem by sealing the gap and “extending” the
- tile flange to create a water barrier behind drywall or like surfaces.
