Microwave paint: how to cover if the enamel has peeled off

Microwave paint must meet the requirements: do not emit toxins, be heat resistant. Inside the microwave oven, specific conditions: microwaves attack water molecules, raising the temperature. Over time, the coating becomes unusable – cracks, scratches appear, in which fat accumulates. How to update the camera yourself, we will tell in this article.

Causes of coating deformation

The microwave oven has to be washed regularly from the inside, because it gets dirty with grease, food residues. If you use a hard brush or abrasive detergents for cleaning, micro-scratches appear on the surface – the paint breaks off, cracks, and peels off. The integrity of the material is damaged – the road to its deterioration is open. Scratches cause rust on the inside. This is not the only problem, in addition to rust spots, there may be other defects – their nature depends on the coating material.

Inner lining material

If the enamel has peeled off in the microwave, do not rush to write it off as scrap – recovery is possible. By painting the inside of the camera, you will extend its service life by another 2-3 years. The nature and causes of deformation depend on the type of coating.

Ceramics

• It is hard, but there is a drawback: it is too fragile.
• Cracks and chips appear on ceramics due to mechanical impact.
• The smoothness of ceramics is a plus, grease does not stick so much to a smooth surface. Any contamination is easily wiped off with a regular foam sponge moistened with soapy water.

Stainless steel

• Durable and reliable, resistant to temperature changes. Minus – it is difficult to clean fatty contaminants.
• Do not clean with abrasive, aggressive products – scratches or stains may appear.
• Cleaned with steam, special products for microwave ovens or kitchen detergents.

Эмаль

• Food enamel is the most short-lived option. It is used in inexpensive models. Due to their low cost, they are in the lead in the rating of buyers.
• Pros: smoothness and lack of pores. Cleans well, especially with regular maintenance.
• Aging and deforming due to natural working conditions. Over time, high temperatures, hot steam, grease, detergents break the structure of the material – it becomes loose.
• The next stage is total destruction. Bubbles appear, the material lags behind the metal in pieces, after a short time the owners discover: their microwave has rusted inside.
• If you look inside an old microwave oven, you can see that the enamel on the ceiling and at the bottom has peeled off the most. The ceiling is more exposed to hot steam rising up during cooking. The bottom deteriorates due to liquid spilling from the dishes in which food is cooked or heated.

If you do not respond to damage, the microwave will crackle, spark. For a long time in this mode, it will not work – it will fail.

The owners are wondering if it is possible to paint the inner walls of the chamber. It is possible, but only in one case – if they are covered with enamel.

What should be the paint

The paint must meet the following requirements:

1. No toxic compounds.
2. Extreme high temperature resistant.
3. Match with original color. This is not technical, but purely aesthetic moment.

What colors are suitable

Most owners of a microwave oven, upon discovering that it has rusted, prefer to throw it away and buy a new one. If wastefulness is not your forte, you will have a question: what to do, how to extend the life of a microwave? Paint the damaged surface. The main thing is to find the right paint, not everyone is suitable for such a thing.

Consider dyes that can be used if the microwave is rusty.

Organic food is the best solution

Recommended brands: KO-5102 and BEP-5297. Minus – the high price of organic dyes.

Pros:

• endure high temperature, alcohol steam, acid, high humidity;
• non-toxic – made for the food industry;
• prevent corrosion;
• waterproof.

The dye adheres particularly well to aluminum and other metal surfaces. Paints are approved by the Ministry of Health, they are allowed to be used in the food industry. Apply with a brush or roller, whichever suits you best.

Conductive

Use Zinga (Belgium) or KO-8111 enamel.

They contain zinc, aluminum, silver or shungite. After drying, the dye turns into a durable layer that is resistant to any negative influences. It can easily withstand temperatures of 150-200 degrees. Adheres well to surfaces. Rarely used due to high cost.

Shungite. Shungite is a rock with high electrical conductivity, strength and density. Heat-resistant and antistatic bases are made from it.

Acrylic automotive

Interested in how to paint a microwave to avoid big expenses? Then acrylic is for you. Compared to the previous options, this is the simplest and most inexpensive dye. It is sold in cans, so it is very easy to use. With one balloon, you can paint the camera completely – in one layer.

Painting stages

We found out how to restore the original beauty, the integrity of the surface. It remains to learn how to properly apply paint. The process can be divided into 4 successive steps:

• Sandpaper cleans the surface from rust, bubbling, peeling paint.
• Degrease with an alcohol solution.
• All openings inside the chamber are sealed with adhesive tape.
• Apply dye. Waiting for complete drying. If necessary, cover with a second layer.

As it turned out, the main reason for premature wear of the microwave is careless maintenance. If you properly clean the chamber of the microwave oven from fatty deposits, there will be no problems. Do not rush to throw away the oven due to coating defects. Choose one of the dyes discussed above and paint it quickly – do not wait for a breakdown.
