When it comes to sealing seams and cracks around windows, doors and siding, H2Us advanced formula delivers better adhesion, flexibility and durability than most sealants in its class.

Formulated for flexibility, it provides 25% joint movement — making it ideal for new construction that will likely experience settling. Made of a UV and water-resistant formula, H2U will not crack or yellow. It is dust- and dirt-resistant, cleans up easily with soap and water and paintable when fully cured. Ideal for both indoor and outdoor use.
