Claims6
A portable unitary seal for effecting a joint in a space between adjacent substrates of a structure, the seal comprising:
- an elongated open-foam compressible backer, said backer containing a centrally located groove;
- an elongated elastomeric strip of cured sealant having a substantially constant width fixed to said backer, wherein the width of said backer is more narrow than said width of said strip of cured sealant at a point adjacent to said sealant;
- and
- said elastomeric strip includes an elongated tang matingly received within said groove.
A unitary portable seal for effecting a joint in a space adjacent substrates of a structure, the seal comprising:
- an elongated elastomeric strip of cured sealant having a substantially constant width disposed on said backer;
- adhesive centrally located substantially along the length of said elastomeric strip;
- wherein
- said backer contains a centrally located groove and said adhesive is located within said groove.
A unitary portable expandable joint for connecting substrates in a structure separated by a space, the joint comprising:
- an elongated compressible open-foam backer for insertion into said space;
- and
- a thin flexible elongated strip of cur ed sealant fixed upon and aligned along its length with said backer, said sealant having a substantially uniform width and having lateral edges deformable from said backer;
- a wet adhesive deployed substantially along each edge of said strip of cured sealant, forming when dry a bond between each of said substrates and the cured sealant.
