An old refrigerator often becomes a “black sheep” in the kitchen, standing out from the updated interior. Purchasing new equipment requires significant investment, while updating the appearance of an existing unit is much cheaper. Repainting the body This is an affordable way to breathe a second life into a household appliance and harmoniously fit it into a design project.
The process of changing color requires patience and strict adherence to technology, otherwise the coating will quickly will lose its appearance. Epoxy and acrylic enamels allow you to create a durable layer that is resistant to mechanical damage and temperature changes. It is important to understand that the result directly depends on the quality of surface preparation.
In this article we will analyze all the nuances of refrigerator restoration, from the choice of materials to final polishing. You will learn what tools are needed, how to avoid leaks and why primer for non-ferrous metals is a mandatory step that cannot be ignored. Following the instructions will allow you to get a professional result without involving craftsmen.
Choosing suitable materials and tools
The first thing a home craftsman faces is the choice of coating. Regular interior wall paint will not work here, as it will not withstand frequent washing and temperature fluctuations. For refrigerators, automotive enamels in aerosol cans or specialized compositions for household appliances are best suited. Aerosol paint Provides an even layer without brush marks, which is critical for smooth metal surfaces.
If you plan to use paint in cans, you will need high-quality short nap roller or spray gun. The roller creates an orange peel texture that hides minor imperfections, but the classic gloss is achieved only by spraying. It is also necessary to prepare degreasersandpaper of various grains and masking tape to protect the seals.
Do not forget about personal protective equipment. It is necessary to work with paints and varnishes in a well-ventilated area using a respirator. Solvent vapors are toxic, and you cannot skimp on safety. Respirator a protection class of at least FFP2 will become a reliable barrier for your lungs during work.
Preparing the surface for painting
The quality of the finishing coat depends 90% on preparation. First, the refrigerator must be thoroughly washed with warm water and detergent to remove grease and dirt. After drying, the surface is treated with a degreaser, for example White spirit or isopropyl alcohol. This will remove invisible fatty films that interfere with paint adhesion.
The next stage is mechanical processing. The glossy factory layer must be matted. For this purpose, sandpaper of P240-P400 grit is used. Your goal is not to remove the paint down to the metal, but to create micro-scratches for better adhesion. If there are chips or rust on the case, they need to be cleaned to bare metal, treated with a rust converter and putty.
⚠️ Attention: Do not use aggressive solvents such as acetone on plastic elements of the case. They can melt the plastic or leave cloudy spots that will show through the new paint.
After filling and sanding, the surface is wiped down again with a degreaser. It is important to remove all dust remaining after sanding, otherwise it will appear on the glossy layer. A sticky napkin or a damp lint-free rag is perfect for this purpose.
☑️ Preparing the body
Primer application technology
Primer is a binder the link between the metal and the finishing enamel. It provides anti-corrosion protection and increases adhesion. For refrigerators, two-component epoxy primers or special adhesive primers for plastic and metal are best suited. Soil Apply a thin layer to avoid drips.
The primer can be applied with a brush, roller or spray. If you are using an aerosol can, keep it 20-30 cm from the surface. Movements should be smooth and back-and-forth. The first layer should be thin, almost transparent, so as not to cause a reaction with the main coating.
The drying time of the soil varies depending on the manufacturer and the room temperature. Usually it ranges from 30 minutes to 2 hours. Don't rush to apply the next layer if the previous one is still sticky. Complete polymerization can take up to 24 hours, but technological drying is often sufficient for painting.
Why do you need a primer?
The primer creates a chemical bond between dissimilar materials. Without it, the paint may begin to peel off in layers at the slightest impact or change in temperature inside the chamber.
The process of painting a refrigerator
The most crucial moment is applying the finishing color. Before use, the paint must be thoroughly shaken for 2-3 minutes to mix the pigment and solvent. The paint temperature should be room temperature, about 20°C. If the container is cold, it should be warmed in your hands or with warm water.
Apply paint in several thin layers. The first layer is “dust”, it goes on translucently. The second and third layers are applied more intensely, but without the formation of “greasy” areas. Interlayer drying is 10-15 minutes. If you apply too much paint at once, it may flow or wrinkle.
It is better to paint doors in a horizontal position, removing them from their hinges. This will avoid vertical drips under the handles and in the corners. If it is impossible to remove the doors, work very carefully, controlling the thickness of the layer. The movements of the spray gun or cylinder should overlap the previous passage by 50%.
After applying the last layer, let the paint dry. Complete curing of the enamel occurs within 7-14 days, but the refrigerator can be used within a day. In the first days, try not to touch the surface or wash it, so as not to damage the fresh coating.
Protective coating and varnishing
To increase wear resistance, a painted refrigerator can be coated with varnish. This is especially true if you used matte paints or want to add a glossy effect. Car varnishes (acrylic or polyurethane) create a durable film that is resistant to scratches and household chemicals.
The varnish is applied similarly to paint: 2-3 thin layers with intermediate drying. It is important to keep the room clean, as any speck of dust that gets on the varnish will be noticeable. Polishing on the surface, after the varnish has dried, it will remove minor defects and give a deep shine.
| Coating type | Time drying | Durability | Difficulty of application |
|---|---|---|---|
| Aerosol enamel | 1-2 hours | Average | Low |
| Acrylic paint (roller) | 4-6 hours | High | Medium |
| Epoxy primer | 24 hours | Very high | High |
| Car varnish | 2-3 hours | High | Average |
⚠️ Attention: Do not use the refrigerator to store food in the first 3-4 days after painting. Chemicals must be completely removed so as not to affect the smell and taste of food.
Care for an updated refrigerator
After restoration, caring for equipment requires a more delicate approach. Use soft sponges and non-abrasive detergents. Melamine sponges can damage a fresh coat of paint, so it is better to avoid them. Regular wiping with a dry cloth will help maintain shine.
Avoid using aggressive solvents, chlorine-containing products and hard brushes. If scratches appear on the surface, they can be painted over with a restoration pencil to match. Care The updated refrigerator will extend the life of the coating for many years.
When rearranging the refrigerator, be careful: new edges may be sharp, and the paint on the ends may be vulnerable to chipped. Use shipping pads. Careful handling is the key to ensuring that your work does not go down the drain.
Is it possible to paint a refrigerator without removing the door?
Technically it is possible, but this is significant more difficult. You will have to carefully seal the seals and hinges with masking tape. The risk of staining the rubber or getting an uneven layer at the bends is very high. Removing the doors guarantees the best result.
How long does it take for paint to dry on a refrigerator?
The tack-to-touch drying time is 1-2 hours, but complete polymerization takes from 7 to 14 days. It is recommended to fully operate the refrigerator, including washing, no earlier than after 3-4 days.
Is it necessary to completely remove the old paint?
No, complete removal of the old paint down to the metal is required only if there is deep corrosion or peeling. In most cases, it is enough to matt the surface well and apply an adhesive primer.
