Barrel repair process
The damaged area on the walls of a barrel or other steel tank must be cleaned. Peeling rust can be removed with any sharp object; the deposits are swept away with a metal brush. There is no need to clean it to a shine, you just need to get to a strong base to apply the composition.
Next, the cannon fat is taken and rolled into a ball of sufficient size to cover the damage existing on the barrel. Then it is pressed against the hole from the inside and spread with a layer of up to 5 mm.If the cannon fat from the ball is not enough, you can add it.
Cannon lard is a water-insoluble preservation material. Therefore, after its use, the water in a leaky container will not change its chemical composition. A rainbow film will not appear on it, as if oil products enter it. The product retains its qualities for a very long time. A barrel repaired in this way may well serve for another 5 or more years, until a new hole appears on the side again, which can also be blocked with cannon fat.
It must be taken into account that the temperature range for using cannon lard is from -50 to +50 degrees Celsius. That is, it cannot be used to repair containers that need to be heated. Due to its thickness, the product can quite reliably repair a container with a through hole with a diameter of 30 mm.
When you buy cannon lard in a jar, inside there may be a substance with a soft consistency, reminiscent of grease. It works as a good, easy-to-apply metal preservative, but is not suitable for repairing holes in barrels. You need to look for pushsalo in briquettes. It's thick. It can be found in auto stores, as well as in auto enamel stores. Cannon lard can be stored for decades, and is also inexpensive, so by purchasing 1 kg of it, you can quickly repair barrels and troughs almost until the end of your life.
