Sustained joint movement
The sealant stretches over 600% and seals gaps up to 3 in. wide while remaining crack-proof through repeated expansion and contraction. A 100% waterproof and weatherproof barrier is maintained under continuous exposure. Low odor and water clean-up simplify application on occupied sites.

Questions about this item
Does the low-odor acrylic urethane formula stay flexible after curing for all-day exterior exposure?
Yes — the sealant stretches over 600 % and remains crack-proof, providing a 100 % waterproof and weatherproof seal that handles continuous outdoor conditions.
Which surfaces must already be clean and sound for the sealant to adhere without a separate primer?
It bonds directly to wood, aluminum, most metals, stone, vinyl, most plastics, drywall, brick and similar substrates when they are free of dust, grease and loose paint.
Can I apply this over existing ASTM C920 Class 25 sealant on the same joint without adhesion failure?
The product meets ASTM C920 Class 25 itself; for best results remove deteriorated old sealant and ensure the joint edges are sound before applying the new bead.
