Cement and Sealer Kiln 1 Lb Dry

Coating and Repair Cement 1 lb. Bag
A permanent high-temperature refractory cement for all types of firebrick kilns. When kept in an air-tight plastic bag, free of moisture, this cement has an indefinite shelf life. In a disposable container (such as a paper cup), mix only the amount you?ll use at one time. Instructions included. 
Kiln Repair Cement 
Kiln Repair cement Mixture: Mix 4 parts dry cement to 1 part water. Measure accurately; mix thoroughly. 
1. The surfaces to be bonded should be flat, matching surfaces. 
2. Use a soft brush or vacuum cleaner to remove dust from the surfaces to be cemented. 
3. Stir cement. Then pour it into a large, flat container, such as an aluminum foil tray. Dip one of the firebrick surfaces into the tray so that the firebrick just touches the cement surface. 
4. Lift the firebrick out of the cement. Working quickly, press the two firebrick surfaces together tightly. Rub back and forth to work the cement into the firebrick pores. Squeeze the surfaces together as you rub them to achieve a very thin firebrick seam. At the first sign of stiffness, stop rubbing. 
5. Once you stop rubbing, do not reposition the pieces or the bond will not hold. Scrape off excess cement without disturbing the firebricks. 
6. Sand smooth after cement dries overnight. 
Kiln Coating Cement 
Kiln Coating Cement Mixture: Mix 1 part dry cement to 1 part water. Mix thoroughly. For thinner kiln coating cement, add water sparingly until it attains the consistency of coffee cream. 
To Coat Kiln Lid: Clean lid with brush and vacuum. Mix cement with water as above. Then brush mixture onto kiln lid to fill pores and leave a thin layer on the surface. Dry for 10 minutes. Brush off excess cement with a wisk broom and wipe down with a soft cloth. Thick layers of kiln coating cement or any contact with kiln wash will crack and buckle the coating.
