As you know, aluminum is quite difficult to paint, this is due to the fact that its coating is very smooth. The more complex the surface structure, the rougher it is, and the larger the contact area with the material. This characteristic is called the pull-out strength of the connection. The problem of complex application of a protective composition to the surface can be solved in two ways, one of them involves rough grinding, while the other involves acid etching. The most common way to prepare the described surface for further decoration is to apply a primer.
Characteristics of VL-02
Primer for aluminum VL-02 is a mixture of domestic production and is manufactured according to state standards. It contains a base in the form of a suspension of zinc crown and an acid diluent. The first ingredient is a yellow anti-corrosion pigment, thanks to which the primer gains adhesion to difficult surfaces. Additional characteristics of the base include impact strength and elasticity. As for the acid diluent, it is an alcohol in an aqueous solution of phosphoric acid. It guarantees etching of the aluminum surface during processing.
Application Features
In order to use the above-described primer for aluminum, it must be mixed and poured into an acid-resistant container, it can be a glass or polyethylene container. For 4 parts by weight of the base, add one part of the acid diluent. The resulting composition should be kept for half an hour, after which it must be mixed well. Aging is required for maximum dissolution of polyvinyl butyral in the alcohol base. It is resistant to water, oxygen, but not alcohol. The shelf life of such soil is 8 hours. This mixture is applied to the surface to be painted in a thin layer, which can range from 6 to 8 microns. You can use a brush or spray. The drying stage will take no more than an hour. You will have to pay approximately 110 rubles per kilogram of this composition.
How long to remove paint
During the factory painting, the aluminum alloy of the boat's hull was treated. As a result of this treatment, a clad (anodic) layer appeared. It is easy to distinguish, it has a yellowish color. The clad layer is designed to stop further aluminum oxidation. Primer and paint also adhere very well to this layer.
If this is possible, then it is advisable not to rip off the anode layer. But, usually, old boats that need painting have areas that have been worn down to metal, with a damaged clad (anodic) layer.
These bald spots will need to be sanded thoroughly.
Features of Nerzhalux soil
If you choose a primer for aluminum, you may prefer Nerzhalux, which is an acrylic adhesive mixture for non-ferrous metals and aluminum. Among its characteristics:
- reliable adhesion with the finishing coating;
- water resistance;
- weather resistance;
- increased adhesion to metals;
- short drying phase.
Using Nerzhalux you can coat not only aluminum, but also galvanized surfaces, as well as aluminum alloys. This one-component primer is intended for ferrous and non-ferrous metals based on modified acrylic copolymers. The mixture is used for the preliminary preparation of products made of stainless and carbon steel, magnesium, aluminum, galvanized and titanium surfaces. This primer for aluminum is able to provide adhesion strength to materials, resistance to water and steam, lubricants, mineral oils, sea water, kerosene, gasoline and other petroleum products. The mixture will also help in cases where the surface is exposed to aggressive gases, salts, solutions of acids and alkalis during operation. This acrylic composition is used to obtain comprehensive anti-corrosion protection of the bases of building structures, which include:
- galvanized roofs;
- metal coatings;
- domes;
- hangars;
- galvanized profile;
- gutters;
- machine parts and other metal products.
Painting of boats and boats made of aluminum | Technology and materials
The process of painting a boat , boat or yacht is significantly different from the process of painting any other product. An important point is what material the boat or boat is made of.
The choice of material for painting will directly depend on whether it is an aluminum boat or a boat with a plastic PVC side.
In this article we will reveal all the secrets of painting aluminum boats and boats, tell you about the technology for painting such products, select the necessary materials and consider all possible color options for such an expensive product.
Features of painting aluminum boats and boats
An aluminum boat, boat or any other watercraft made of aluminum has a number of advantages over the same products made of other materials. They have high strength, low weight, they are very easy to transport and launch, and therefore, thanks to these advantages, aluminum boats and boats are more popular.
In order to protect an aluminum boat from the aggressive effects of water and give it an attractive appearance for a long time, manufacturers of boats and boats use epoxy primer and polyurethane paint for aluminum to . In the painting system, epoxy primer perfectly protects the side of an aluminum boat, and polyurethane paint (in a glossy or matte version) perfectly emphasizes the beauty of the curves and gives its uniqueness to each model. It is important to understand that ordinary polyurethane enamels and epoxy primers in direct contact with water can lose interlayer adhesion (adhesion of paint layers to each other), so it is necessary to choose only high-quality and specialized materials for painting water transport .
The most important feature of painting an aluminum boat or boat is careful preparation for painting. Here, preparatory grinding and degreasing of the surface before painting plays a very important role.
It is the preparation of an aluminum boat for painting that gives an excellent coating result and eliminates the possible occurrence of problems with finishing coatings, especially if the boat is painted in unique, non-standard metallic or pearl colors.
Technology for preparing and painting an aluminum boat or boat
Since an aluminum boat is always in an aggressive environment (in the open air and on water) and aluminum has very high chemical activity, the coating of the boat should first of all have a protective function and, secondly, a decorative one. Based on this, a painting system for aluminum boats was developed, which has the following formula:
Epoxy primer (2 layers) + Polyurethane enamel (glossy / matte)
Using such a painting system , an aluminum boat is no longer susceptible to oxidation and acquires a rich, beautiful color in a pastel or metallic version.
Preparing the boat for painting must be done very carefully. Pre-grinding is done with abrasive paper with P120 grit. Surface degreasing must be done only with high-quality products from trusted manufacturers.
Materials for preparing and painting an aluminum boat or boat
Choosing the right materials for painting an aluminum boat is the key to future painting success. Today on the market there are many primers and enamels for aluminum made in Russia and abroad.
Manufacturers such as AKZO NOBEL (International SeaLine), Tikkurila, MOBIHEL, Hempel, DUXON, SEALINE and many others offer special compounds for boats and boats.
Among the well-known domestic paintwork materials for painting aluminum boats, the following options are considered: alkyd enamels XV-124 and primers FL-03K, VL-02, VL-023, as well as enamels of the GF and PF series.
When choosing a material for painting, the criteria for comparison will be such characteristics as composition, durability, possible color palette, material consumption per 1 square meter. meter and, accordingly, the price of the product.
Proven system for painting aluminum boats with professional paints and varnishes LECHLER and ALCEA
Thanks to the experience and skills of technical specialists, a special system for painting aluminum boats with professional paints and varnishes LECHLER and ALCEA was developed, which was tested on many models of boats and aluminum boats in the harsh climatic conditions of Russia and the waters of the Gulf of Finland.
The painting system for aluminum boats from LECHLER is as follows:
Painting cycle for aluminum boats from ALCEA:
These painting cycles for boats and boats made of aluminum are developed taking into account the basic needs of manufacturers and the needs of future owners of such an expensive product.
The described
painting systems do not require the use of additional layers of varnish and intermediate sanding, which greatly simplifies painting and reduces the time for producing one boat without losing the quality of the finished paintwork.
Polyurethane enamels ALCEA and LECHLER have very high elasticity, which prevents chipping on the surface of an aluminum boat. These enamels combine very high strength, good elasticity, good interlayer adhesion and an excellent uniform appearance of the finished paint coating.
These systems can be used both in production and at home if you have the necessary equipment and a painting chamber.
Colors for painting aluminum boats and boats
Of course, in addition to the technical characteristics of the paint coating , the owners of boats and yachts will always be interested in their aesthetic appearance, which is why manufacturers often come up with unusual options for painting the side and interior decoration of the boat.
In the line of paint manufacturers such as LECHLER and ALCEA, there are all kinds of shade options for painting aluminum boats and yachts. For example, the boat's finish can be pastel, with a shiny metallic effect, or with sparkling mother-of-pearl.
An important point is that previously spectacular colors ( metallics and pearlescents) could only be produced using acrylic paints or in an automotive painting system (varnish base) and these materials could not be used for painting aluminum boats and boats, since they did not have the necessary properties, but today this problem has been solved and an aluminum boat can be painted in any spectacular colors such as xerallic, mother-of-pearl or metallic.
Today, there are a lot of for painting a boat, boat or yacht made of aluminum
Before painting a boat yourself or when developing a painting cycle for aluminum boats in production, it is always necessary to obtain advice from technical specialists in the sale and implementation of paintwork materials.
This will allow you to avoid possible problems with the adhesion of materials, problems with the finished paint coating and problems with the further operation of such an expensive product as an aluminum boat or yacht.

Method of use
Before using the Nerzhalux primer, mix well until smooth. Application must be carried out on a dry surface that has previously been cleaned of rust, dust, dirt and oils. If there is rust on the surface, it should be cleaned to Sa 21/2 using the abrasive blast cleaning method. Application can be done using a roller, brush, airless spray or air tool. If necessary, the primer can be diluted to working viscosity, using solvents R-648 or R-5A.
Do I need to remove the old coating?
If the paint is practically intact , and you want to repaint the boat yourself or renew the old paint, then there is no need to remove the coating.
It will be enough to treat the hull of the vessel with a three-dimensional Scotch Brite abrasive sponge. This sponge is used to rub surfaces for better adhesion of old and new paint.
The ideal option is not to remove the original paint and primer at all, just use Scotch Brite to matte the surface.
If only selective repairs are needed, then areas with damaged paint must be treated.
If the paint is very peeling , then more thorough preliminary preparation is required. There are two ways to pre-prepare an aluminum hull, which will depend on the overall condition of the boat:
- Wash.
- Cleaning up.
It is not recommended to remove paint by heating; the aluminum body can lead to damage!
Temperature
The above-described primer for aluminum for boats will dry to degree 3 within half an hour, but only if the room temperature is maintained within 20 °C. After drying at a temperature of 20 ° C, you can apply further layers of varnish and paint materials. It is necessary to use the soil in a temperature range from +5 to +30 ° C, while the room must have a relative air humidity that does not exceed 80%.
Consumption and precautions
Before purchasing a primer, it is important to familiarize yourself with the composition consumption, which can vary from 80 to 120 g/m2; this is true if the thickness of one layer is equal to the limit from 8 to 15 microns. Professionals advise applying about 2 layers. On sale you can find this primer, which is presented in a yellow base color. It is important to take precautions when applying this primer. When carrying out internal work and after its completion, it is necessary to ventilate the room, and in the process of applying the mixture, you must use personal protective equipment. The cost of one kilogram of such primer is 233 rubles.
Types of primers for aluminum
In the process of processing a metal surface, the following can be used:
1. Primers in an aerosol can.
2. Two-component primer composition.
The first option is used when processing small aluminum parts. For example, a bicycle frame or rims. Working with such a primer will not cause problems, so you can even use it on the balcony.
Two-component primers are used in the processing of boat hulls, automobile parts, as well as other versions of aluminum products that have a large surface area to be coated.
Description of Body 960 Wash Primer
This primer for aluminum (aerosol) is easier to use. For example, Body 960 Wash Primer is sold in different packaging, including in aerosol form. The mixture is a high-quality anti-corrosion acid-curing primer, which is made on a polyvinyl butyl base. It can be mixed with an activator and is intended for complete and local use. With its help, you can pickle rust and prevent it from spreading further. This mixture has the quality of high adhesion to non-ferrous metals. After completion of the drying phase, it guarantees anti-corrosion protection of the surface. The applied layer dries in 10 minutes, after which the base does not require sanding and can be painted with any two-component mixtures. Using this primer, you can protect aluminum from salt, moisture, and also give the surface characteristics of resistance to atmospheric, mechanical and chemical influences.
