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.\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e12-1\/2 lb Tub or 25 lb Tub\u003c\/li\u003e\n\u003cli\u003eRated up to 2200\u003cspan data-contrast=\"auto\" lang=\"EN-US\" class=\"TextRun SCXW248019089 BCX0\"\u003e\u003cspan class=\"NormalTextRun SCXW248019089 BCX0\"\u003e°F (1204°C)\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eColor may vary\u003c\/li\u003e\n\u003cli\u003eMay be painted once dry\u003c\/li\u003e\n\u003cli\u003eMinimum 24-hour dry time\u003c\/li\u003e\n\u003cli\u003eDoes not require heat to cure\u003c\/li\u003e\n\u003cli\u003eApproximate coverage: 12-1\/2 lb will cast a 12″ x 12″ x 1-1\/2″ square\u003c\/li\u003e\n\u003cli\u003eIndoor and outdoor use\u003c\/li\u003e\n\u003cli\u003eNot for direct food contact\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-lineheight=\"38.25px\" data-fontsize=\"25.5\" class=\"yikes-custom-woo-tab-title yikes-custom-woo-tab-title-directions fusion-responsive-typography-calculated\"\u003e\u003cstrong\u003eDirections\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStir the dry contents of the container thoroughly. Using a plastic bucket or container, add one quart cool, clean water per 12.5 lbs. dry mix. Only mix an amount that can be used within 20-30 minutes after adding water as cement sets up fast. Mix thoroughly, taking care not to lose any water. While wearing gloves, take a handful of the material and form it into a ball. Toss the ball an inch into the air a dozen times. If it breaks apart, it is too dry. If it slumps or sags down through the fingers, it is too wet. Excess water lowers the strength of the bond and increases time needed to set.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFirebox:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDampen work area lightly with water.

Do not permit surface to dry out during this period. Dried castable cement still contains chemically combined water that is given off as steam at higher temperatures.
