4. Install sealant into the prepared joints when the joint is at the mid-point of
its expansion and contraction cycle. Place the nozzle of the gun, either
hand, air, or electric powered, into the bottom of the joint and fill entire
joint. Keep the tip of the nozzle in the sealant; continue with a steady flow
of sealant preceding the nozzle to avoid air entrapment. Avoid overlapping
the sealant to eliminate the entrapment of air. Tool as required to properly
fill the joint.
5. Adhere to all limitations and cautions for the polyether sealant as stated in
the manufacturers printed literature.
B. Cracks:
1. For best performance sealant should be gunned into crack to a minimum of
a 1/4" in depth. Place the nozzle of the gun, either hand, air or electric
powered, into the bottom of the crack and fill entire crack. Keep the tip of
the nozzle in the sealant. Continue with a steady flow of sealant preceding
the nozzle to avoid air entrapment. Avoid overlapping the sealant to
eliminate the entrapment of air. Tool as required to properly fill the crack.
2. Adhere to all limitations and cautions for the polyether sealant as stated in
the manufacturers printed literature.
