Clay chimineas are useful and beautiful for outdoor cooking. In times past, Chimineas were used primarily in Mexico, but have gradually become a common outdoor accessory. They are used for barbecues and are a beautiful addition to a backyard or patio. Once you have the chiminea installed, you will need to seal it. Sealing is a simple process and will ensure that the chiminea will not crack from the heat and keep it from getting water damaged.

Step 1

Clean the surface your chiminea. Wipe its surface with a damp cotton rag and make sure that there are no ashes or debris on the surface.

Step 2

Apply the sealer to the outside of the chiminea according to the manufacturer's directions. Use a rag to spread the sealer on the whole outside surface of the chiminea. But do not apply sealer on the inside of the clay stove as you use it to cook food.

Step 3

Rub in the sealer thoroughly on the entire outside surface of the chiminea. Use a circular motion to rub the sealer in. Then wait for 5 days before you use the chiminea.

Step 4

Seal the inside of your chiminea. Spread three inches of sand over the bottom of the firebox. The sand will help protect the bottom of the chiminea from extreme heat.

Step 5

Make a fire inside the firebox using wood chips and let the fire burn out. Wait for the chiminea to cool then make another fire. Repeat the process until you've made 5 to 10 fires. The soot and the ashes from the fires will seal the pores and cracks inside the firebox.
