Rutland Dry Mix 211 Refractory Mortar 10 lb – USA-Made High-Temp Mortar for Fireplaces, Fire Pits, Kilns & Ovens

Overview

Rutland Dry Mix 211 is a USA-made refractory mortar designed to join or repair masonry flue tiles in gas or wood fireplaces and in chimneys for wood, coal, or pellet stoves. This dry-mix cement requires only water, a simple mix, and a trowel to seal and bond flue tiles with dependable performance—and without complicated steps. The product can also serve as a parge coating, a thin over-coat that helps fireboxes achieve a smooth, even finish in a rich dark gray.

While heat curing is not mandatory, applying heat can strengthen the bond. The formulation is aimed at high-temperature environments, providing a practical solution for ongoing maintenance or restoration projects around high-heat masonry. It is suitable for kitchens and workshops where durable, heat-resistant joints are valued, including pizza ovens, kilns, and forge settings.
