Lanco Ultrathane WB Clear CC 82218 – 10.1 FL. OZ

This clear, low‑odor, water‑cleanup sealant adheres well to a wide range of common building substrates, including painted and unpainted wood, metal, masonry, concrete, stucco, and many plastics, without staining or discoring sensitive surfaces.
Once cured, it forms a durable, flexible, mildew‑resistant bead that does not crack, crumble, or peel under severe weather or repeated joint movement, and can be overcoated with most latex or oil‑based paints after skin formation.

Key benefits for contractors and DIY users:

Up to 50% joint movement capability – handles thermal expansion, wind sway, and structural movement without failing.

Waterborne, low odor, easy cleanup – tools and spills clean up with water; more user‑friendly than solvent urethanes.

Clear finish – blends discreetly on glass, metal, and light substrates where color matching is critical.

Excellent adhesion – bonds to painted and unpainted wood, metal, masonry, concrete, stucco, and many plastics.

Mildew resistant, weatherproof – resists mold growth and stands up to rain, UV, and temperature cycling.

Paintable – can be topcoated with latex or oil‑based paints after initial skin forms.
