Epoxy paint - features and varieties of the product
Among all types of paint and varnish coatings, epoxy paints deserve special attention ... They are popular due to their incredible resistance to aggressive factors, as well as their long service life.
Basic properties of paint.
Epoxy paints and varnishes are used to treat surfaces that are subject to regular mechanical damage (abrasion). For example, it can be used when decorating wall and floor surfaces.
Due to the fact that there are no harmful substances in the composition of such a finishing material, it is also safe for painting living quarters, as well as pieces of furniture. It is also used for finishing fences, exterior facades and outdoor decor.
Epoxy coatings have the following main features (characteristics):
- Resistance to mechanical damage, as well as no risk of cracks and chips during the operational process.
- Water resistance - the coating is capable of repelling liquid, due to which it is used for baths or other rooms that have a high level of humidity. They also use these types of paints for catamarans and boats.
- Versatility - suitable for painting surfaces made of brick, concrete, stone, plastic, wood and metal.
- The drying time is from 1/2 to 1 day, it all depends on the air temperature.
- Resistant to ultraviolet rays.
- A huge selection of shades, due to which you can create an original and unique coating on any type of surface.
- Ease of application, the ability to independently use at home.
Also paints made on the basis of epoxy resins protect the surface from fungal colonies, corrosion and mold.
Paints made on an epoxy basis are made from resins. Due to this, they create a fairly durable coating layer on the surface.
As part of such finishing materials, there are other types of components:
The number of certain components will directly depend on the specific area in which you will apply the paint and varnish material. For example, a thermal coating is used to paint ovens with a minimum amount of solvent, binders and the obligatory presence of fiberglass.Depending on the specific form in which epoxy paints and varnishes are produced, the following types can be distinguished:
Next, let's take a closer look at all the varieties.
Epoxy powder coatings usually used for processing various metal parts that are required for industrial purposes. They are not used at home, because a special coating (heating type chambers) should be used to cure the coating. Powder epoxy paints and varnishes for metal, after drying, create an extremely durable and resistant protective coating that can withstand not only a mechanical type of exposure, but also exposure to high temperatures (up to +1000 degrees), dirt and moisture.
The disadvantages of such a finishing material include the following:
- Difficulty in performing work - such a paint and varnish material for metal requires knowledge of application technology.
Moreover, polymerization of the coating will not be possible without special equipment.
- High material cost.
- Inability to process plastic and wood surfaces.
Metal elements treated with such a paint and varnish material can be used for up to 15 years without losing the main properties of the coating.
This type of epoxy type compounds is the most popular.
They can be used not only in industry, but also at home. They are available as two separate components, which must be mixed before starting work. The binder is a mixture of epoxy-type resins, which will be the base of the paint and varnish material. They have a liquid, homogeneous and flowing consistency. A hardener is a component without which the coating will not harden on the surface.
It is usually in powder form. Moreover, the composition of the paint and varnish material contains coloring pigments. Based on this, a finishing material is intended for such a surface, and there are the following varieties:
Epoxy two-component composition for metal, concrete or wood is economically dispersed.
This will be explained by the fact that you can independently make the required amount of materials, and its remainder will be stored for a long time until the next staining. When working with such formulations, it is important to observe the mixing proportions of the ingredients. This is required so that after drying, the coating can retain its protective qualities for a long time.
Aerosol finishing materials are convenient for painting hard-to-reach places where it is impossible to reach with a roller or brush. The spray creates a perfectly thin and even coating.
It is for this reason that it is often used to paint cars. Epoxy aerosol enamel for metals is not prone to smudges, it is elastic and will not crack under the influence of low temperatures.
Manufacturers produce the following types of paints and varnishes:
Such paints for wood and concrete are not used in view of the fact that their consumption is much higher than when processing a simple two-component epoxy paint.
Before applying the epoxy coating, the surface must be properly prepared. The final result largely depends on this stage. If the surface is poorly prepared, the level of adhesion to the paint and varnish material will be greatly reduced, which aggressively affects the life of the coating. Such paint for a new concrete floor is applied only after the concrete screed has dried perfectly (not earlier than after 4 days).
Usually, the new floor should not be leveled before painting, since it will not have chips or other defects without this, but for perfect adhesion of the finishing materials, it must be sanded. To do this, you can use coarse sandpaper or a stiff brush.
After sanding, remove cement dust from the surface. When processing an old concrete floor, it is necessary to eliminate all irregularities in advance with an epoxy putty. The preparatory work of wooden surfaces, in addition to preliminary sanding, also involves the application of a primer.
It will greatly improve the degree of adhesion and promote even distribution of coatings. The epoxy type of primer can also be used as a base and for other types of paints and varnishes, for example, acrylic. Before starting metal processing, it is imperative to remove the old paint layer and perfectly clean the surface. to ensure perfect adhesion, experts advise degreasing all metal parts. A solvent is perfect for this.
After you have fully processed the surface (and still prepared), you can start direct painting. Depending on the size of the coating, you can use tools such as:
- Roller - it is convenient to apply epoxy-type enamels on concrete, metal or wood on a flat and large surface (floor and walls). Such a tool will help to evenly distribute the layer and avoid smudges.
- Brush - used for painting small parts, and it is also convenient to apply paints with a brush to the corners or to places where there are irregularities.
By the way, the surface treatment should be carried out in a couple of layers to improve the protective properties and ensure an even beautiful color.
The first one can be applied by the manufacturer, and only after complete drying (at least 12 hours must pass) can you start re-processing. It is important that the second layer is even and neat, all strokes should be made in the same direction.
The following precautions should be taken when handling such finishing materials:
It should be remembered that this finishing material, after preparation, must be applied as soon as possible. To increase its lifespan, certain specialists are diluted with a solvent for epoxy paints and varnishes. But such measures will be extreme and can degrade the quality of the coating, as well as its protective property.
