Expansion Joint Sealant
Expansion joints absorb movement between building elements, so the sealant must stay flexible and bonded as the joint opens and closes. The manufacturer's JL1017 neutral plus silicone sealant lists expansion joint sealing among its applications, and the JL200 window and door silicone sealant states a movement figure in its published description.
Confirm the joint width, expected movement and substrate before ordering.
An expansion joint needs a backing rod behind the sealant. The rod sets the sealant depth, stops the sealant bonding to the back of the joint, and lets the bead flex as designed. Without it, the sealant bonds on three sides and splits down the middle when the joint moves. State the joint width and depth in your inquiry so the right rod and sealant combination can be confirmed.
