These dry-mix refractory mortars are made from high temperature cements and carefully selected aggregates that will not expand or tear the mortar apart when heated. Once dried, these products are non-water soluble and more acid resistant than any other type of product used in these applications.

2. If, after mixing, the product still appears dry, add a little clean water and remix it thoroughly.
3. For firebrick installation, keep the joints 1/16″ to 1/8″ thick.

This product may take longer to dry if the joints are thciker than 1/8″, and/or if conditions are extremely humid (such as after a recent rain).  To enhance the drying in such conditions, open the damper, place a fan in front of it, or use other means to get some air or heat passing by the installation.
