Protecting the hidden cavities of the body and the bottom of the car from the aggressive effects of moisture and reagents remains one of the priority tasks for the owner, especially in a harsh climate. Cannon lard It is a decades-proven preservative that effectively displaces water and creates an elastic, non-drying film on metal surfaces. Unlike bitumen mastics, this material does not crack at low temperatures and is able to independently tighten small mechanical damage to the coating.
Proper application of this composition requires an understanding of its physicochemical properties, since the product is supplied in a solid state and needs preheating to operating temperature. GOST 15975-78 It regulates the main quality parameters, but in practice, motorists often adapt the application technology to their needs, using various solvents and tools. It is critically important to observe the temperature regime of heating, since overheating above 90 ° C can lead to loss of anticorrosion properties and fire of vapors.
In this article, we will discuss in detail all stages of car preparation, methods of applying preservative in hidden cavities and on open surfaces, as well as ways to safely remove it if necessary for repair. You will learn how to dilute the composition for working with a spray gun, how to protect rubber elements and why. cannon-baker Often chosen instead of modern chemistry for preservation of long-term storage techniques.
What is cannon bacon and where is it used
This material is an ointment mass of yellow or light brown color obtained by thickening oils with ceresin and petrolatum with the addition of anticorrosive additives. The main purpose of the substance is the preservation of metal parts and nodes exposed to atmospheric corrosion. Due to its high adhesion and water-repellent properties, cannon-baker Ideal for handling rapids, rangers, wheel arches and the bottom of the body of passenger and freight transport.
The uniqueness of the composition lies in its ability to maintain elasticity over a wide range of temperatures, from minus 50 ° C to plus 50 ° C. This means that the coating will not run down in the heat and will not become brittle in the cold, continuing to protect the metal. Technical Vaseline and oils that are part of the composition provide deep penetration into microcracks and rust, stopping the development of oxidative processes.
- 🚗 Treatment of hidden body cavities (thresholds, racks, spars) to prevent corrosion from the inside.
- 🚜 Conservation of agricultural and construction equipment for a period of long winter storage.
- ⚙️ Protection of threaded joints and suspension hinges from acidification and exposure to salt solutions.
- 🛡️ Creating a temporary waterproofing layer on metal surfaces before painting or packaging.
It is worth noting that the material is not paint or decorative coating. Its purpose is purely functional protection. When applying to visible parts of the body, it should be borne in mind that the layer is sticky and collects dust and dirt on itself, therefore, cannon-baker They are most often used in hidden places or under an additional protective screen.
Necessary tools and surface preparation
The quality and durability of anticorrosion protection directly depend on the thoroughness of preparatory work. Applying a preservative on a dirty, wet or rust-exfoliating surface will not give the desired effect, since the protective layer will not be able to tightly adhere to the metal. Before starting work, the car must be thoroughly washed, paying special attention to the arches and bottom, and completely dry with compressed air or naturally.
To work, you will need a set of tools that allows you to heat the composition and evenly distribute it on the surface. Since the material comes in solid bars or cans, it needs to be heated to a liquid state. This should be done in a water bath or using a building hair dryer, but in no case on an open fire to avoid ignition.
☑️ Preparation for anticory
An important step is to protect the elements that should not get the composition. Rubber seals, plastic cabin parts and brake mechanisms can suffer from aggressive components or simply become unusable due to loss of rubber elasticity. Use paint tape and polyethylene to insulate such areas.
| Tool/Material | Appointment | Features of use |
|---|---|---|
| Construction hair dryer | Warming up the lineup at the bank | Do not overheat locally, warm evenly |
| Needle syringe | Pumping into hidden cavities | Allows you to enter difficult places |
| Hard-pile brush | Application to open areas | Convenient for arches and bottoms, creates a dense layer |
| Pulverizer | Coverage of large areas | Requires strong dilution with solvent |
| White Spirit | Degreasing and diluting | Use only in a ventilated room |
After preparing the surface and tools, you can begin breeding the composition. For open surfaces such as the bottom and arches, a thicker consistency is often used to create a strong armoring layer. For hidden cavities, where it is important to penetrate deeply, the composition is made more liquid.
Technology of heating and preparation of mixture
The main difficulty of working with cannon-baker It is necessary to transfer it from a solid state to a liquid state. At room temperature, it is a dense, squishy mass that cannot be applied uniformly. The melting process requires caution: heating is best done in a water bath, placing a jar with the composition in a container with boiling water. This provides a gentle and controlled heating without the risk of burning or ignition.
If you use a building hair dryer, direct the hot air flow to the walls of the metal container with lard, constantly stirring the contents with a wooden or metal stick. The temperature of the working mixture should be approximately 80-90 ° C. At this temperature cannon-baker It becomes fluid like sunflower oil, but it does not start to smoke or emit caustic fumes.
⚠️ Attention! It is strictly forbidden to heat cannon bacon on an open fire of a gas burner or blowtorch directly. The vapors of petroleum products ignite, which can lead to a fire or an explosion of the container.
Can I mix cannon bacon with motor oil?
Some masters add spent motor oil to increase fluidity and reduce the cost of the mixture. However, this reduces the protective properties of the preservative and makes the layer more liquid, which can lead to its drainage in the summer. It is better to use special solvents, such as white spirit or gasoline "Kalosha", in a ratio of 1: 5 to obtain the desired viscosity.
To improve the penetrating ability in the microcracks of rust, a solvent can be added to the molten mass. Usually one part of the fat takes 4-5 parts white-spirit Or gasoline-solvent. The mixture is thoroughly stirred until a homogeneous consistency is obtained. It is important to prepare the mixture in small portions, since the solvent quickly evaporates, and the composition thickens again.
Methods of application on the bottom and open surfaces
The treatment of the car bottom requires the creation of a dense, continuous layer capable of resisting the mechanical effects of sand and stones. Apply cannon-baker It is most convenient to use a wide hard brush or spatula if the composition is thick enough. The movements must be rubbing to ensure that all irregularities of the metal and microcracks of the old paint are filled.
If you use a spray gun, make sure the mixture is well diluted and filtered through a shallow net to avoid clogging the nozzle. Spraying allows you to cover a larger area faster, but the layer is thinner, which may require re-treatment. The optimal layer thickness for the bottom is 200-400 microns.
- 🖌️ Apply the material sequentially, capturing the previous not yet dried strip to avoid borders and overlaps.
- 🌡️ Work is better to carry out in a warm room (garage) at a temperature not lower than +10 ° C for better adhesion.
- 🧤 Be sure to use personal protective equipment: gloves, glasses and a respirator, as solvent vapors are toxic.
Pay special attention to the edges of the arches, welded seams and places of attachment of aggregates. This is where corrosion most often begins. After applying the first layer, let it dry for 20-30 minutes, then apply the second layer to ensure reliability. Cannon lard It dries for a long time, finally polymerizing after a few days, so in the first days after processing it is better to avoid trips on wet snow or dirt.
To check the quality of application, swipe your finger (in a glove) on the dried area every other day. The finger should remain slightly greasy, but should not be stained with black plaque. If the finger is black, the layer is too thin or too little solvent.
Treatment of hidden body cavities
Protecting hidden cavities is the most important step, as it is within sills, racks and spars that corrosion develops most quickly due to condensation and poor ventilation. For high-quality processing, it is not enough to simply smear the material from the outside. It is necessary to ensure the penetration of the preservative in all corners of the hidden space.
The ideal tool for this is a special anti-corrosion gun with a long spray tube or a large medical syringe with a needle. In the hidden cavities are usually pumped more liquid composition so that it can flow under the culling and into the joints of sheets of metal. Cannon lard in the liquid state has excellent fluidity and is able to displace moisture residues from hard-to-reach places.
⚠️ Attention! When handling hidden cavities, be sure to dismantle plastic plugs, lights and skin elements to access the process holes. Blind spraying without access to the cavity will not give results.
The processing technology consists in sequential filling of the cavity from the bottom up. Insert the nebulizer tube into the process hole and, pressing the trigger, slowly lift the tool, evenly covering the walls. After processing, leave the car with the doors open and the hood for several hours to ventilate and evaporate the solvent.
To enhance the effect in the hidden cavities, you can place fabric harnesses impregnated with the composition or use special wax candles that melt from the heat of the body and spread, creating an additional protective layer. But classic cannon-baker In liquid form, it copes with this task no worse if sufficient pressure is provided during spraying.
The main secret of processing hidden cavities is redundancy. The material should start to flow out of all the technological holes, which ensures the full filling of the volume and displacement of air and moisture.
How to wash off cannon bacon and remove excess
In situations where you need to repair the body, digest the thresholds or simply remove excess protective layer, the question arises about how to effectively wash off. cannon-baker. Since the material is designed for resistance to water and aggressive environments, it will not be possible to remove it with conventional detergents. The use of organic solvents will be required.
The most effective means of removing is white-spiritGasoline "Kalosha" or specialized degreasing agents for body repairs. Also well-established aerosol cleaners of bitumen spots, which are often used for wheel arches. They soften the preservative, making it easy to erase with rags.
The cleaning process is as follows: apply the solvent profusely to the contaminated surface and let it work for 3-5 minutes. During this time cannon-baker It'll soften. Then mechanically remove the bulk with a spatula or a hard brush, and wash the remains with a cloth soaked in the solvent. For hard-to-reach places, a toothbrush can be used.
- 🧼 Use rags made from natural fabrics, as synthetics can dissolve under the action of aggressive chemicals.
- 💨 Provide powerful ventilation in the room, as pairs of solvents with large volumes of work can cause dizziness.
- ♻️ Dispose of used rags and solvents in special containers, do not drain them into the sewer.
If the layer is old and covered with a crust of dirt, preheat the surface with a building hair dryer. The warm composition is removed much easier and faster. After complete cleaning, be sure to degrease the surface before applying a new protective layer or painting.
Is cannon bacon harmful to rubber parts?
Classical. cannon-baker according to GOST is not aggressive to rubber and plastic, unlike some bitumen mastics based on Solvent. However, prolonged exposure of rubber seals in the solvent medium used to dilute the fat can cause them to swell or lose elasticity. Therefore, when processing thresholds and arches, it is recommended to glue rubber elements with paint tape or remove excess composition from rubber immediately after application.
How long does the protection of cannon bacon last?
The service life of the coating depends on the operating conditions of the car. On average, the layer on the bottom retains its properties for 2-3 years, after which revision and local restoration are recommended. In the hidden cavities, where there is no mechanical action of sand and stones, cannon-baker It can work effectively for 5-7 years or more, as it does not dry out or crack over time.
Can I apply cannon bacon to rust?
Yes, one of the key features of the material is the ability to penetrate loose rust, displace moisture from it and stop further oxidation. However, before application, it is still recommended to clean the loose foci as much as possible mechanically to ensure better adhesion. On pure metal without rust, protection lies more efficiently.
