Rust-oleum 261998 Flexible Joint Sealant 9 Oz Concrete

Product Description

The RUST-OLEUM 261998 is a two-component, self-leveling, 100% solids polyurea flexible joint sealant packaged in a 9 oz tube cartridge. It is formulated to fill interior control joints and new construction saw cuts on horizontal concrete surfaces. The sealant delivers 10-15% movement of the installed joint width, making it suitable for industrial floor environments that receive heavy-duty vehicle traffic. Licensed flooring contractors and industrial maintenance technicians install this product as part of concrete floor preparation and protection systems.

This sealant is intended for industrial and commercial interior floor applications where concrete control joints or saw cuts require flexible, durable sealing. It is compatible with most floor coating technologies, including acrylic, epoxy, and polyurethane topcoats, allowing crews to seal joints before or as part of a broader floor coating project. The product can be applied across a wide temperature range of -40 degrees F to 120 degrees F, supporting installation in cold storage, warehouses, manufacturing floors, and similar environments.
