Moisture Seal
The Step-Ko Products Moisture Seal utilizes the combination of the SK2400 gel filler and the seal capabilities of the SM-65A fabric tape to form a moisture barrier between the concrete ring and steel ring interface. The chime seal tape is gray in color and is U/V resistant. The seal provides excellent adhesion characteristics to both the steel and concrete surfaces.
