Disassemble as much of your cast-iron coal stove as possible. Use a screwdriver or wrench to remove any bolts. Use an air chisel, which offers much more power than you can get using a wrench or screwdriver, if the bolts are rusty and hard to remove.
Sandblast all the parts of the stove to remove any rust. Use a stiff wire brush to get into the detailed and hard-to-reach areas.
Wipe off all of the sandblasted parts with a damp rag to remove all traces of sand, or you will run the risk of having a less than perfect finish.
Remove any cracked and deteriorating seam cement, if your stove has it. Use a hammer and chisel to remove stubborn parts, but make sure to remove it all before trying to add new cement or it will not adhere.
Use a putty knife to add new cement to any necessary seams.
Paint all the individual parts of the vintage cast-iron stove with a high temperature paint if you plan to use the stove for heating your home. Use regular, cheaper enamel paint if you intend to use the cast-iron coal stove for decoration only. Allow the paint to dry according to manufacturer's recommendations.
Give everything a second coat of paint if necessary, especially if you plan on burning fires in the stove, and allow the paint to dry thoroughly.
Put the pieces of the vintage cast-iron coal stove back together using brand new bolts.
Things You Will Need
- Screwdriver or wrench
- Putty knife
- If any portions of your vintage cast-iron coal stove have nickel-plated parts, take these parts of the stove to a reputable plater for stripping and re-plating.
- Not all coal-burning stoves have the cement seams. If yours does not, skip those steps and continue with the rest of the restoring process.
