RUTLAND Castable Refractory Cement is an exceptionally strong dry-mix cement that chemically sets and dries as hard as brick. Just add water! Perfect for casting into custom designs because it holds its shape while drying, just add water. It can even be used as the sole material when casting a solid stove bed or outdoor oven. Also works to fill large holes or cracks in masonry, replace mortar, and for tuckpointing.
