Acidic primer – what is it, what is needed for

In the world of painting and coating, acidic primers are a need. These primers have a specific function; they ensure longevity and durability by strengthening the bond between the paint and the surface. You can paint projects with professional results if you know what an acidic primer is and why you need it.

Fundamentally, an acidic primer is any primer that contains acid; the most common type is phosphoric acid. This component is essential because it enables the primer to etch into the surface, forming a layer that is textured. This textured layer helps the next coats of paint stick better, avoiding chipping, peeling, and other types of wear and tear.

Metal surfaces are one of the main uses for acidic primers. Painting metals can be difficult, especially if they are exposed to harsh environments. To ensure proper paint adhesion, an acidic primer is used to prepare the metal surface by eliminating contaminants and oxidation. In applications like automotive, industrial, and marine where surfaces need to endure a lot of wear and tear, this is especially crucial.

Acidic primers are used on metal as well as other materials that need strong adhesion. The correct primer can make a big difference when working on large-scale industrial tasks or do-it-yourself projects at home. Acidic primers improve the appearance and durability of the final coat of paint by giving it a strong foundation.

All things considered, acidic primers are essential to the painting process. They guarantee that, even in adverse circumstances, your paint job will hold up. You can select the best products for your projects and get better results if you are aware of their features and benefits.

Acid or reactive primer – what is it, what is needed for

It’s important to comprehend what phosphate soil is in order to decide which of the many funds available on the market should be used to create an anti-corrosion layer. Both a liquid solution and cylinders are available for purchase. Phosphoric acid is used in the composition, and zinc can be added to help achieve additional benefits like good adhesion and protection against rust formation. Phosphate soil is widely used for the preliminary processing of automobile bodies.

It can only be applied as the initial layer; additional soil must be applied before paints and varnishes can be applied on top.

Chemical components in the composition provide a protective layer against corrosion. The layer also has mechanical protection, setting it apart from other primer solutions. Epoxy compounds cannot be painted over because their components overlap the acidity property. However, acidic primer has a lot of advantageous qualities.

  • Resistance to high -temperature exposure;
  • Water resistance, primer layer does not react with salt and water. Thanks to this, the beneficial properties of the coating are preserved in the winter;
  • Resistance to the negative effects of surrounding factors, withstands the effect of gasoline, oils and other compositions;
  • A metal surface treated with grass soil will be able to withstand the various influences of natural factors, while the treatment is not needed;
  • The fast pace of drying, the subsequent layer can be applied in five minutes.

What is the feature of the composition

Because the primer is acidic in metal, it effectively coats the product’s surface, providing a durable barrier against moisture damage and assisting in the prevention of corrosion. Experts recommend applying solutions in sufficient quantities to completely eradicate rusted zones. They also suggest choosing to prioritize high-quality and well-known brands.

As previously indicated, application is done right away on metal, and an aerosol is typically chosen to be sprayed with the product. The degree stage ought to have been made earlier. To achieve a leveling effect, an acrylic primary mixture is applied once it has completely dried.

Applying to surfaces with remnants of old putty or products that have not been thoroughly cleaned is prohibited because doing so could cause the layer to move away from the base too quickly.

The creation of chemical protection, not mechanical protection, is the primary distinction from acrylic or epoxy primers. As a result, other than the insulating primer, no external means are used.

An improved agent called acetic acid coats the product’s surface, providing a long-lasting layer that protects against moisture damage and helps to prevent corrosion.

A unique kind of base coat called an acidic primer is applied before painting or coating in order to improve adhesion between the surface and the topcoat. It works especially well on non-porous surfaces, such as metals, where conventional primers may have trouble bonding. Acidic primers help create a smoother, more durable finish by preventing peeling and flaking by forming a chemically reactive layer. In addition to providing extra defense against rust and corrosion, this primer is crucial for industrial and automotive applications where durability and surface integrity are important.

The main types of acidic soils

There are various types of planting soil; being aware of their characteristics will make it easier to select the best one. There are four primary categories identified:

    One -component, which can be applied immediately, there is no need, to breed it additionally before work. It is standardly sold in aerosol form, although there are also liquid options that can be applied using a spray gun. After drying, they proceed to applying acrylic agents, which also in the composition have a hardener;

It is essential to thoroughly read the manufacturer’s instructions before applying the composition because each tool may have slightly different application guidelines.

Preparation of the body for the primer

There are specific guidelines that must be followed when painting in order to achieve the desired quality outcome. According to experts, you must take action with the following technologies:

  1. Begin with the preparation of the room where the body will be painted. It is necessary to clean it, wipe the dust so that it does not settle to the surface.
  2. Then the car itself is prepared, the old coating is removed completely, reaching the metal coating directly.
  3. You should examine the car after that to decide on the future enamel.
  4. Elements of the machine that should not be painted are covered.
  5. It is necessary to degrease the base.
  6. Pull the surface.
  7. Put a putty.
  8. The remedy is applied.

A brush or aerosol products work well for the stages of cleaning and degreasing. Applying reactive soil becomes easier when the second option is chosen because of the more even coating.

Work needs to be done while wearing safety gear. The master needs to wear protective gloves, clothes, and dense shoes in addition to a respirator.

With reactive soil, you can erect a sturdy layer that keeps corrosion from forming on the metal base.

Acid soil methods

There are various applications for the tool. Everyone selects the option that works best for them; some options require specific tools and conditions, and are only complete with production staining. There are differences between the following methods:

  • Using a brush;
  • Using acidic soil in the can;
  • By complete immersion, it is usually used to cover small elements on a production scale;
  • Spraying with electric energy;
  • Electric disposal. This method involves immersing part of the product into the reservoir, where it becomes a charging element of the chain.

It is essential to follow safety protocols. Health issues may arise from soil getting under the skin and in the mucous membranes. It is therefore essential to wear protective clothes and a respirator.

Although the product is always applied before staining, the circumstances determine whether or not to grind the surface. Using a skin with fine granularity is preferable. For a high-quality outcome, you require:

  • Choose quality products;
  • Compulsory following instructions and technical measures;
  • The experience of such work is needed.

The following metal materials can be processed with compounds: steel, aluminum, stainless steel, and galvanizing.

How to properly primer

Strict adherence to the operating guidelines is required in order to prime the metal’s surface with shaking soil. Experts advise carrying out the subsequent steps:

  • The surface is cleaned of all types of pollution, the old coating should be removed;
  • Degenerate by any suitable tool;
  • A primer solution is applied to the dry surface. For small products, a brush is suitable, in other cases it is better to choose a spraying methodology. Do not make a thick layer, it should be thin;
  • Wait a couple of hours until the completion of the chemical reaction;
  • Then you can proceed to processing with ordinary primers;
  • Sometimes it is required to putty the surface.

How much phosphate soil dries

The drying duration may vary depending on the acid soil brand, so it’s best to follow the manufacturer’s instructions. The next layer can be added in five minutes on average. It is usually best to wait 30 minutes for the layer to completely dry before processing additional primer compounds.

Examples of acidic primer

You can only achieve a good body covering by selecting high-quality products. If novices are familiar with well-known brands that are well-liked by industry experts, their decision-making process will be simpler. Popular species will therefore be further described.
