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

So that metal products do not lose strength, and also have an attractive appearance, they should not have 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 about how to choose and correctly use rust paint in the article.

What it is?

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

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

Many formulations 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.

Major stripping is not required before applying it. The composition can be used on previously painted surfaces.

The paint dries quickly over rust, lays down evenly, in a dense 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 intended to protect the metal product from rust and to give it an attractive appearance.

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

Rust paint does not require lengthy preparation. Before applying it, it is enough to clean off the peeled metal and immediately start painting. Such formulations dry much faster.

Three main differences rust paints:

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

Varieties of compositions for rusty metal

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

1. Epoxy. These formulations are based on silicone polymer resins. They are not afraid of heat, but they have a high level of toxicity. Therefore, they should not be used for domestic needs.
2. Oil. At the heart of any oil paint is oil and drying oil. Such compositions transform rust worse than others, therefore they are recommended to be used only for painting structures indoors.
3. Alkyd. This is the most economical option. Such compositions are distinguished by good adhesion, adhere firmly to the surface.
4. Acrylic. They are composed of polymer resins and anti-corrosion modifiers. Such paints have several advantages at once: they do not have a pungent smell, are resistant to friction, moisture, and heat. They can be used to paint metal products both inside the building and outside.
5. Hammerheads. These formulations contain silicones as their base. Aluminum powder, crushed glass and other fractions act as auxiliary components. Such 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 counterparts.

Selection features

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

1. If the metal structure is inside the room all the time, then you can use oil compositions.
2. When it is necessary to save on paintwork, alkyd paints come to the rescue.
3. If the product is regularly exposed to heat and other environmental factors, but a person rarely comes into contact with it, you can use epoxy paint.
4. For uneven surfaces and for a roughened, metallic sheen, hammer paint can be purchased.
5. Acrylic paint can be called universal. They are suitable for all types of metal, it can be used for indoor and outdoor work. Such compositions do not have a pungent odor, are not toxic to humans.

When buying, you need to pay attention to the composition of the dye. The 3-in-1 mark indicates that the product converts corrosion, primers and paints the metal surface.

Terms of use

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

1. First, the site must be prepared. To do this, remove peeled rust with a stiff brush or sandpaper. If its thickness does not exceed 100 microns, then cleaning can be omitted.
2. When the whole product needs staining, care must be taken to ensure that the composition does not get on the surrounding objects, walls and floor. To do this, they are covered with polyethylene.
3. If processing of a small surface is required, then the intact areas are sealed with masking tape.
4. Spray paint is applied by holding it at a distance of about 15 cm from the surface. If the composition is poured into cans, use a spray bottle or brush.
5. After painting, the product is left to dry. The exact time depends on the type of paint.
