ABSTRACT:
A method of sealing a joint between two adjacent members comprises the steps of forming a gap between the members to be sealed and then introducing a bead of resilient solid material into the gap. The bead is subsequently treated to render it temporarily plastic or fluid so as to cause it to adhere to the facing edges of the members. This treatment can best be effected using a hot air blower. The bottom of the bead may be provided with a non-adhesive strip to prevent adhesion to the bottom of the gap, or the process may be performed in such a way that the bottom portion of the bead is not fused so that it does not adhere to the bottom of the gap.
