Devcon 11420 Dark Gray Filler Putty 3 Lb

Product Description

The DEVCON 11420 is a dark gray, ceramic-base filler putty used to repair and restore surfaces in demanding maintenance and repair applications. It delivers a shear strength of 2200 psi and a tensile strength of 2200 psi, making it suitable for structural gap-filling and surface rebuilding where adhesive performance is critical. Each package contains 3 pounds of putty. The 45-minute working life gives technicians adequate time to mix, apply, and shape the material before it begins to set. Full cure is reached in 7 days. Licensed tradespeople, maintenance technicians, and industrial repair professionals are the primary installers of this product.

The DEVCON 11420 is formulated for use on ceramic, concrete, metal, and plastic substrates. It is well suited for patching worn pump housings, pipe fittings, concrete surfaces, and equipment frames encountered in HVAC, plumbing, and general industrial maintenance. It performs within an operating temperature range of 55 degrees F to 90 degrees F, making it appropriate for indoor maintenance environments and controlled mechanical spaces. The putty form allows direct hand or tool application without the need for specialized dispensing equipment.
