Rust-oleum 266733 Flexible Joint Sealant 22 Oz Concrete

Product Description

The RUST-OLEUM 266733 is a two-component, self-leveling polyurea joint sealant formulated for filling control joints and saw cuts in horizontal concrete surfaces. At 100% solids, it delivers a durable, flexible seal rated for 10-15% movement of the installed joint width. The 22 oz tube format uses a self-contained dual-component cartridge that simplifies mixing and application. It is intended for industrial and commercial floor environments where heavy-duty vehicle traffic is a regular condition, and it is typically installed by flooring contractors, concrete finishing crews, and industrial maintenance technicians.

This sealant is suited for interior concrete floor applications including warehouses, manufacturing facilities, distribution centers, and other high-traffic industrial spaces. It is applied into control joints or new construction saw cuts prior to or in conjunction with floor coating systems. The product is compatible with acrylic, epoxy, and polyurethane floor coatings, making it a practical choice when the slab will receive a topcoat after joint filling.
