Everlastic®
2nd Seal
Williams Everlastic 2nd Seal is placed prior to the primary seal assuring a
watertight seal should the primary seal fail. The 2nd seal can be used
in vertical or horizontal applications or as a primary seal when appearance
is not an issue.

| Wide Joint Seal
Everlastic® Wide Joint Seal is
a pre-factory cured strip of silicone sealant adhered to rectangular polyurethane backer.
The polyurethane backer is wider than the joint opening and the silicone is of a lesser
width than the joint opening. The backer is compressed and placed into the joint, thus
holding the cured silicone in a vertical position and leaving a recess on either side of
the cured silicone and parallel substrate. A wet silicone sealant is caulked and tooled
into the recess bridging the cured silicone and the interface of the parallel substrate.
