How to remove chips on a refrigerator: choosing paint, preparation and painting

Chips on the body of a refrigerator are not only an aesthetic problem, but also a potential threat to the durability of the equipment. Even slight damage to enamel or metal can become an outbreak corrosion, especially in conditions of high humidity in the kitchen. Unlike scratches, which are often masked with polishes, chips require a more thorough approach: proper surface preparation, selection of compatible materials and careful application.

In this article we will examine 7 proven methods coating restoration - from budget solutions with automotive paints to professional kits for household appliances. You will learn how to choose a color with up to 95% accuracy, what tools you will need to prepare the metal, and why painting without a primer reduces the service life of the repair by 3-4 times. Let us separately dwell on the nuances of working with stainless steel, plastic panels and refrigerators with a textured coating (for example, Samsung Family Hub or LG InstaView).

Why chips on the refrigerator more dangerous than scratches

A scratch damages only the top layer of enamel or varnish, while a chip exposes metal base or plastic. In the first case, the risks of corrosion increase significantly: moisture, condensation and even steam from cooking penetrate microcracks, triggering oxidative processes:

• 🔹 Old refrigerators (until 2010) with a thin layer of enamel - their metal often begins to rust within 2-3 months after damage.
• 🔹 Models with magnetic doors (for example, Indesit BIAA 13 or ATLANT MXM 1705) - the magnetic field accelerates the corrosion of bare metal.
• 🔹 Refrigerators in coastal regions or houses with high humidity - salt in the air acts as a rust catalyst.

Plastic panels (for example, on Bosch KAN92VI30 or Liebherr CPes 4066) are less susceptible to corrosion, but even here chips create problems: they accumulate dirt, grease and bacteria, which are difficult to wash off. In addition, plastic without a protective coating turns yellow over time under the influence of UV rays (even from a kitchen lamp).

How to choose paint based on the type of refrigerator coating

Error in choosing paint - the main reason why repairs last for several months at most. Refrigerator manufacturers use different types of coatings, and each requires its own approach:

For precise Use the color selection RAL code of your refrigerator. It can be found:

• 📄 In the device passport (section "Technical Specifications").
• 🔍 On the sticker on the back of the refrigerator (usually next to the serial number number).
• 🖥️ On the manufacturer's website - enter the model into the search and check the specifications.

If the RAL code is not available, take it with you to the store photo of a chip on a flash drive —many paint sellers offer a tinting service based on a sample. An alternative is to order paint online at VIN code of the refrigerator (relevant for premium brands like Miele or Smeg).

Step-by-step instructions: surface preparation

80% of success depends on the quality of preparation. If you skip at least one step, you risk that the paint will peel off in a few weeks. Here is a mandatory checklist:

1. Cleaning and degreasing. Use white spirit or a specialized degreaser (for example, APP Cleaner). Not suitable: alcohol, acetone, dishwashing detergent - they leave a film. For plastic, it is better to use isopropyl alcohol (70% concentration).

2. Removing rust. For small lesions it is suitable rust converter (Zincar or Rust Converter). data-i="132">or sandpaper with a brush or sandpaper P80 (for metal only!).

3. Putty (if necessary). Fill deep chips (more than 0.5 mm) two-component auto putty (for example, Novol PlusApply with a spatula in 2-3 layers, drying for 10-15 minutes each time. sandpaper P400 to a perfectly smooth surface.

⚠️ Attention: When working with putty and primer use respirator —their dust is toxic. The room must be well ventilated, and the air temperature should not be lower than +18°C (otherwise the materials will not polymerize).

The best methods of painting: from a spray can to an airbrush

Choice method depends on the size of the chip, the type of coating and your experience. Let's consider all the options from the simplest to the professional:

1. Paint in a can (for chips up to 5 cm)

Spray cans with acrylic auto enamel (for example, Motip or Dupli-Color) give an even coating without smudges. Technology:

1. Shake the can for 2-3 minutes (the ball inside should knock).
2. Apply the first layer from a distance 20–25 cm light zigzag movements.
3. Let dry for 15 minutes, then repeat 2-3 times.

For glossy surfaces after painting, polish the area paste 3M 09374 this will remove shagreen and even out the shine.

2. Brush + paint in a jar (for spot chips)

Suitable for repairing chips the size of a coin. Use synthetic brushes s. with a thin pile (for example, Da Vinci Maestro Kolinsky No. 2). Apply paint. crosswise: first horizontal strokes, then vertical. Avoid thick layers - they take longer to dry and can stretch.

For plastic panels, add to the paint plasticizer (10% of the volume) - this will prevent cracking due to temperature changes (relevant for refrigerators with No Frost).

3. Airbrush (for large areas)

A professional method that requires skill. An airbrush (for example, Iwata HP-BCS) allows you to apply paint as thinly as possible, simulating the factory coating. The compressor pressure should be 1.5–2 bar, and the distance to the surface should be 10–15 cm. Use water-based paints (for example, Createx Auto Air) to avoid toxic fumes.

⚠️ Attention: When painting with an airbrush be sure use a hood or work outside. The smallest particles of paint in the air are explosive in high concentrations.

How to paint stainless steel: features

Stainless steel requires a special approach: standard paints do not adhere well to it due to the smooth surface and high thermal conductivity. Here is algorithm for stainless steel models (for example, Smeg FAB32 or Whirlpool ART 9810):

1. Matting the surface. Treat the chip with sandpaper P320, then P600 - this will create micro-roughness for better adhesion.
2. Applying a primer. Use primer for stainless steel (for example, Permatex 81849it contains zinc particles that protect the metal from corrosion.
3. Painting. The optimal choice is epoxy paint (Rust-Oleum 7579838).Apply in 2 layers with intermediate drying for 1 hour.
4. Protective layer. After drying, coat the repaired area transparent varnish for metal (Krylon 1311) - this will extend the service life by 2 times.

To restore the shine of stainless steel after painting, use GOI paste (green or red depending on the degree of tarnishing). Apply it felt polishing pad at low drill speeds (maximum 1500 rpm).

What to do if the paint on stainless steel begins to peel off?

If bubbles or peeling appear 1-2 weeks after painting, the problem is insufficient adhesion. Remove paint with a solvent (App Paint Stripper), re-matt the surface and use adhesive promoter (for example, Sika Aktivator) before priming.

How to mask chips on plastic panels

Plastic (for example, on refrigerators Bosch Serie 6 or Gorenje NRK6191) is more difficult to paint due to low adhesion and the risk of cracking. Other methods work here:

• 🎨 Restoring pencil. For small chips (up to 3 mm) suitable Edding 8400 Paint Marker. It contains a pigment that is resistant to moisture and UV rays.
• 🧴 Vinyl stickers. Companies like Oracal or 3M offer films to match the color of the refrigerator. The sticker not only masks the defect, but also protects the plastic from fading.
• 🔧 Liquid plastic. For deep chips, use Plasti Dip - it creates an elastic coating that does not crack during vibration (relevant for refrigerators with inverter compressor).

If the plastic around the chip has turned yellow, treat it before painting plastic restorer (Meguiar’s PlastX). This will return the original color and improve adhesion to the paint.

How to prolong the result: care after painting

Even perfectly executed repairs lose their appearance over time if the rules of care are not followed. Here's what you need to do:

• 🧼 Wash the refrigerator only with a soft sponge with neutral detergent (pH 6–8). Abrasive powders and brushes damage the fresh coating.
• 🌡️ Avoid temperature changes. Do not place the refrigerator next to the stove or radiator - this leads to microcracks in the paint.
• 🛡️ Apply protective wax. Once every 3 months, treat the repaired area car wax (Turtle Wax Ice) - this creates a hydrophobic layer.
• 🔌 Control the humidity. If the room humidity is above 60%, use silica gel absorbers (for example, Silica Gel) next to the refrigerator.

For stainless steel, after washing, wipe the surface dry microfiber in the direction of the “fibers” of the metal - this prevents streaks. Treat plastic panels once every six months UV protective spray (303 Aerospace Protectant) to avoid fading.

FAQ: Frequently asked questions about chip repair

Can I use car putty for a refrigerator?

Yes, but only two-component polyester (for example, Novol Plus or Body 999). It is resistant to moisture and temperature changes. Putty based on nitrocellulose (NTs-008) cannot be used - it turns yellow and crumbles over time.

How long does it take for the paint to dry? refrigerator?

It depends on the type of paint and conditions:

• 🔘 Acrylic auto enamel — 24 hours until complete polymerization (after 6 hours you can gently touch).
• 🔘 Epoxy paint — 48 hours (at a temperature of +20°C).
• 🔘 Plasti Dip —4 hours until tack-free, but full strength is achieved after 7 days.

You can speed up drying with an infrared lamp (keep at a distance of 50 cm, temperature no higher than +40°C).

How to paint over a chip on a refrigerator with a textured surface?

For models with a relief (for example, Samsung Family Hub or LG InstaView) the following is suitable:

1. Special textured paint (Rust-Oleum Textured).
2. Applying paint through stencil with a pattern, repeating the factory pattern.
3. Use gel varnish (Gel-Nail Top Coat) to create a volumetric effect.

Before painting, practice on a piece of plastic or cardboard to find the right consistency.

Is it possible to paint a refrigerator without unplugging it?

Technically it is possible, but not recommended. Vibration from a running compressor can cause uneven paint application. In addition, solvent vapors in high concentrations are explosive. If it is impossible to turn off the refrigerator:

• 🔌 Work with open door (this will reduce the heating of the compressor).
• 😷 Use respirator with carbon filter.
• ⏳ Paint in 2-3 approaches with breaks for ventilation.

What to do if there are streaks left after painting?

Stains appear due to:

• 🎨 Too thick paint - dilute it thinner for acrylic paints (10–15% of the volume).
• 💨 Incorrect distance when spraying - keep the can at a distance of 20–25 cm.
• 🌡️ Low room temperature - paint should be applied at +18–25°C.

To remove stains:

1. Wait for complete drying (24 hours).
2. Polish the surface 3M paste 09376 using a polishing machine (speed no higher than 1000 rpm).
3. If necessary, apply another thin layer of paint.
