shower seals combine a rigid pvc strip with
Sealux-N silicone. To install Sealux the strip
is filled with Sealux-N silicone and planted
over the joint.
Each strip has a green tape (the red line) applied
to the inside face. This tape is a silicone
bond-breaker. The silicone will not bond to
this part of the strip.
The silicone only bonds to the upper part of
the strip at x and the ledge at y.
joint movement the silicone releases off the
green tape and stretches like an elastic band
to create a flexible bridge between the strip
at x and the ledge at y.
This ‘bond-breaker’ tape creates
great flexibility in the silicone, the ‘shielding’
effect of the strip over the silicone promotes
durability and hygiene in the shower environment.
