Pourable, Self-Leveling Sealant For Roof Penetrations

Pro Pack Urethane Pourable Sealer

PRO PACK is a two-part, self-leveling urethane designed for ChemCurbs, E-Curbs and other roof penetration seals. In both new construction or repairs, PRO PACK'S fast setting technology allows for minimal down time and the ability to complete your roof project quickly and efficiently.

It is designed for use in horizontal self-leveling, sealing and waterproofing applications. When properly mixed, PRO PACK cures to a tough rubber mass with excellent low temperature elasticity and adhesion.

PRO PACK resists deterioration caused by weather, joint movement, water and ice. It is also resistant to oils, fuels, and many chemicals.

PRO PACK is 100% solid rubber. PRO PACK has no solvents, no volatile organic content, (V.O.C.) and will not shrink after application.

PRO PACK has excellent adhesion to most construction materials.

PRO PACK contains no asphalt or coal tar.

Roofing

PRO PACK is used to fill warranted ChemCurb penetration seals on "low-slope" roofing systems. On a positive slope, allow PRO PACK to partially cure to trowel grade consistency, then top off ChemCurb with a trowel. It is also a waterproof sealant for bridging the transition between different types of roof construction.

Expanded Polystyrene Foam

PRO PACK has excellent adhesion to and is compatible with Styrofoam, EPS, and urethane foam insulation. It bonds and waterproofs tapered foam sheets to form an inseparable composite that is highly resistant to wind uplift.

Expansion Joints

PRO PACK can be used to waterproof cracks and expansion joints in concrete and asphalt pavement, as well as cement roofing construction. Embedding polyester into wet PRO PACK, and top dressing with PRO PACK is recommended.
