Rust-oleum 301826 Plastic Roof Cement 10.1 Oz Cartridge

Product Description

The RUST-OLEUM 301826 is a fibered, asphalt-based plastic roof cement in a 10.1 oz cartridge, delivering a strong, flexible seal designed to resist cracking over time. Packaged in black, it applies fast and smooth without stringing, making it a practical choice for roofing contractors and building maintenance professionals working on flashing repairs, foundation sealing, and similar exterior applications. The fibered asphalt formula bonds reliably to a range of substrates and holds up under the movement and weathering typical of exterior roofing assemblies.

This product is suited for residential and commercial roofing applications where a durable cartridge-applied sealant is required. It is designed for installing or repairing roof flashings at valleys, parapet walls, gravel stops, stacks, vents, and monitors. It also performs well for sealing cracks in exterior foundation walls and chimney walls. The 301826 can be used in combination with fiberglass mesh, polyester fabric, or roll roofing material for permanent patching and repair work.
