1-Part is a moisture curing, pourable sealant designed for use in pitch pans and warranted ChemCurb/E-Curb penetration seals. 1-Part 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 has resilient “elastomeric” properties and excellent adhesion to most construction materials.


Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation. Do not extend 1-Part with foreign materials or liquids. The seal surface will skin over and will be water tight in approximately 1 hour. Do not use if rain is anticipated within 4 hours. Please contact customer service for application guidelines with temperatures below 32°F (0°C). Do not use on TPO without the use of TPO primer. Do not use on Hypalon. Smooth APP membranes require a granulated target. This product sets rapidly upon exposure to moisture.
