Rating of paints for rust: features, pros and cons, cost, reviews

To ensure that metal products do not lose strength and also have an attractive appearance, they must be free of corrosion.

It will not be possible to avoid its appearance if the surface is not painted or has chips. In these places the metal will begin to oxidize.

If this has already happened, rust paint comes to the rescue. With its help you can quickly and effectively get rid of corrosion.

Read the article about how to choose and correctly use rust paint.

What it is?

Rust paint is a universal product that can be applied to both cleaned and corroded surfaces.

It not only masks existing defects, but also prevents further damage to the metal.

Many compounds act as a primer. Therefore, the surface does not need to be leveled before applying them. Rust paint is used for both ferrous and non-ferrous metals.

No major cleaning is required before use. The composition can be used on previously painted surfaces.

Rust paint dries quickly and goes on smoothly and in a thick layer. This is possible thanks to unique additives, including:

• low concentration polymers,
• alkyd resins,
• organic solvents.

Difference from other types of dyes

Regular paint is designed to protect a metal product from rust and to give it an attractive appearance.

There is a difference in the features of using coloring compositions. Conventional paint requires high-quality preparation of the product. It is cleaned of rust, then degreased and primed. Only after these manipulations can you begin the main staining procedure.

Rust paint does not require long preparation. Before applying it, it is enough to clean off the exfoliated metal and immediately begin painting. Such compositions dry much faster.

Three main differences rust paints:

• transforms corrosion;
• acts as a primer;
• creates a monolithic waterproof layer that protects the metal from aggressive environmental factors.

Types of compositions for rusty metal

There are several types of rust paints. Their main difference is the substance that underlies:

1. Epoxy. These compositions are based on silicone polymer resins. They are not afraid of heat, but have a high level of toxicity. Therefore, they should not be used for household needs.
2. Oily. The basis of any oil paint is oil and drying oil. Such compositions convert rust worse than others, so it is recommended to use them only for painting indoor structures.
3. Alkyd. This is the most economical option. Such compositions have good adhesion and adhere firmly to the surface.
4. Acrylic. They consist of polymer resins and anti-corrosion modifiers. Such paints have several advantages: they do not have a strong odor, are resistant to friction, moisture, and heat.They can be used to paint metal products both inside and outside the building.
5. Hammer. These compositions contain silicones, which form their basis. The auxiliary components are aluminum powder, crushed glass and other fractions. This paint perfectly masks any irregularities, and after drying it creates a rough effect with a metallic sheen on the metal surface. Hammer compounds are more expensive than their polymer analogues.

Features of choice

Before making a choice in favor of one composition or another, you need to decide for what purpose it will be used:

1. If the metal structure is always indoors, then you can use oil compounds.
2. When you need to save on painting work, alkyd paints come to the rescue.
3. If the product is regularly exposed to heat and other environmental factors, but people rarely come into contact with it, you can use epoxy paint.
4. To treat uneven surfaces, as well as to create a rough effect with a metallic sheen, you can purchase hammer paint.
5. Acrylic paint can be called universal. They are suitable for all types of metal and can be used for interior and exterior work. Such compositions do not have a strong odor and are not toxic to humans.

When purchasing, you need to pay attention to the composition of the dye. The “3 in 1” mark indicates that the product transforms corrosion, primes and paints the metal surface.

Terms of use

Depending on the container the paint is in, the method of applying it will differ. However, the sequence of actions is always the same:

1. First, the site needs to be prepared. To do this, remove loose rust using a stiff brush or sandpaper. If its thickness does not exceed 100 microns, then cleaning does not need to be carried out.
2. When the entire product needs painting, you need to make sure that the composition does not get on surrounding objects, walls and floors. To do this, they are covered with polyethylene.
3. If treatment of a small surface is required, then seal the undamaged areas with masking tape.
4. Spray paint is applied, holding it at a distance of about 15 cm from the surface. If the composition is poured into jars, use a spray bottle or brush.
5. After painting, the product is left to dry. The exact time depends on the type of paint.
