1-Part Pourable Penetration Sealant

Restricted Supply : Limited Quantities Available, Order now!! Next Estimated Delivery 12 Weeks

1-Part Pourable Sealer is a fast skinning, moisture-cure, self-leveling, high performance, waterproofing sealant for pipes, penetration seals, and odd shapes in exterior or interior environments with horizontal application. It is suitable for application in damp, dry, or cold climates. 1 Part is solvent free, contains no isocyanates and will not shrink upon curing. 1 Part does not “out-gas” or bubble on damp surfaces as urethane sealants often do. 1 Part has resilient “elastomeric” properties and excellent adhesion to most construction materials. 1 Part can be used effectively in many difficult construction site conditions and cures in wet or dry climate conditions and at low temperatures (32°F / 0°C). 1 Part’s low durometer accommodates greater movement in penetration seals than typical urethane sealants.
