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.
Claims13
A process of sealing a joint between two adjacent members such as deck planks, cladding panels and the like carried on a subjacent member for support thereby,
- said process comprising the steps of
- forming a channel at the junction between at least said two adjacent members, said channel having two adjacent edge faces of said two adjacent members facing one another across the width of said channel and a channel bottom face formed as one of a shoulder of a said adjacent member, an underlying support on which said adjacent members are carried and an underlying substrate supporting said adjacent members,
- introducing a bead of resilient solid material into said channel, and
- treating said resilient solid material bead to render it temporarily one of plastic and fluid whereby to cause it to adhere to said facing edge faces of said two adjacent members, said treatment of said material of said bead being such as to maintain the resilient elasticity of the material of said solid bead subject to such treatment whereby to maintain the seal thus formed even in the event of substantial relative movement of said two adjacent members sealed by said bead.
