The spray gun is a tool designed for applying pigment, primer, varnish, enamel, and other compositions to horizontally and vertically arranged surfaces. Sprayers are sold in a wide range – the market offers various types of models for domestic and professional use. Consider the types of paint sprayers, their pros, and cons, the rules of choice, and the subtleties of operation.
For painting walls and ceilings in an apartment, a brush or roller is often used. The use of these tools is justified if you need to process a small area of land. However, when planning large-scale work, it is recommended to purchase a special paint sprayer. It is much better than a brush and paints roller for several reasons:
- allows you to apply the coloring pigment and other compositions in a thin and even layer;
- promotes economical consumption (reduces the amount of material used by up to 40% compared to the roller);
- eliminates the formation of streaks and the appearance of bristles from the brush, which significantly improves the quality of repair work;
- contributes to a significant increase in labor productivity.
The paint sprayer is easy to use, so even a beginner will understand the subtleties of its operation. Manufacturers attach detailed instructions to the device, which describe the rules for using the equipment – if you have any questions, you can find detailed information in them.
The disadvantages of spray guns include their high cost compared to the roller. However, their price is compensated by the high speed of the work performed, which causes the rapid completion of painting activities. By using a spray gun, you can save not only the time spent on repairs but also the effort.
Another drawback characteristic of spray guns is the release of particles of the sprayed material into the environment.
Household mechanical models of paint sprayers have a similar device. Visually, the simplest devices resemble a pistol with a lever, equipped with a handle and a tank for the sprayed material. The container for the pigment, depending on the design, is located in the upper, lower, or side part of the spray gun. Paint sprayers are also classified by type of drive.
These are the simplest in design and budget models. They are used for applying water-based compositions, lime, and chalk solutions. The design of the mechanical models includes a solution container and outlet tubes. Such devices are designed for small painting works, whitewashing of gardens and street trees.
Advantages of manual models:
- financial accessibility;
- reliability due to the simplicity of the design;
- pressure injection without additional resource consumption.
The mechanical spray gun has a number of significant disadvantages. The main disadvantages include low productivity, the inability to ensure constant pressure, uneven coloring when the lever is pressed unevenly.
Manual paint sprayer in comparison with other types gives the lowest quality of color. However, if you need to process small areas, it is best to give preference to such models-this as the best alternative to a brush or roller.
Manual spray guns include the Zitrek SO-20 device. The weight of the device is 6.8 kg, and the tank capacity is 2.5 liters. Maximum capacity-1.4 l / min. Designed to work with compositions whose density does not exceed 1.3*103 kg/m3.
The paint sprayer has a metal body, due to which it is resistant to various types of mechanical influences.
Electric-powered paint sprayers are in demand among home craftsmen due to their compact size, lightweight, and medium price range. The paint is sprayed by the equipment due to the pressure created by the built-in pump. Since there is no directional airflow in such sprayers, their coloring quality is inferior to pneumatic sprayers. However, such a tool can become a reliable assistant to home painters.
Advantages of electric spray guns:
- easy to manage;
- the ability to perform work at different angles due to the elastic intake tube;
- good performance;
- low power consumption.
The disadvantages of such equipment include the dependence on the 220 V electrical network and the limited range of the wire length.
The disadvantages of users also include the need for preventive measures to increase the durability of the device.
The top of the most popular devices for painting with an electric drive includes the model Wagner Spraytech 0518080 Control Spray Max. It occupies the first place in the rating of network paint sprayers.
The unit features patterns ranging from 1/2″ to 12″ wide depending on your settings, allowing for better control and precision while working it. Thanks to the provided adjustments, it is possible to adjust the intensity of the supply of the coloring material.
The HVLP technology, which is synonymous with Wagner sprayers, uses a large volume of air and low pressure to spray the paint material into the smallest particles. The model is equipped with a 1 qt metal cup, 1.5qt plastic cup a 20ft hose, in addition to a viscosity cup and a user manual
Such spray guns are classified as professional. The devices are considered universal since they can be used to apply various compositions to the surface. For example, they allow you to varnish wooden products, paint the walls with water-based paint, treat them with putty, primer, and other means. Pneumatic paint sprayers are designed to perform a large amount of work – their productivity can reach about 400 m2 in 1 hour.
Other advantages of pneumatic equipment include:
- ensuring a constant pressure, due to which the applied composition lies on the surface in an even layer;
- ability to adjust the operating parameters;
- speed of repair work.
The paint spraying of pneumatic devices is carried out thanks to compressed air. The necessary pressure in the system is pumped using a compressor – it must be purchased separately, which leads to additional financial costs. Significant disadvantages also include the presence of hoses that reduce the mobility of equipment and the high noise level of the operating compressor.
Among professional painters, the most popular spray gun is Astro Pneumatic Tool 4008. Reliable and high-performance equipment is designed for applying decorative finishing coatings on various surfaces. The weight of the device is 2.5 pounds, the capacity is 1-quart capacity dripless cup, Fully adjustable wide fan pattern control.
The metal body of the device determines its resistance to mechanical influences, and the polished chrome coating reliably protects the spray gun from corrosion and premature wear.
Mobile spray guns are considered to have a power source in their design. Thanks to the battery, the device is mobile-this is its main advantage. It does not depend on the electrical network, due to which it can be operated in the field.
The disadvantages of battery models include a limited time of continuous operation (no more than half an hour for most devices available on the market) and a higher price compared to network sprayers. In addition, due to the built-in battery, the devices have a large weight, which complicates their operation.
Tips for choosing
In order not to be disappointed in the purchase, you need to pay attention to several important parameters when choosing a paint sprayer.
- Tank material: The most reliable models are equipped with an aluminum container with an anti-corrosion coating. In terms of strength, plastic barrels are much inferior to metal ones.
- Location of the pigment tank: In most models, it is located at the top or bottom. For painting the ceiling, it is best to choose a device with a side or lower location of the container, for walls – with an upper one.
- Nozzle diameter: The optimal dimensions range from 1.3 to 1.5 mm. With tools with such nozzle diameters, it is convenient to work with most types of paints, while obtaining a high-quality uniform coating.
- Device performance: The speed of work directly depends on this indicator. The performance shows the volume of solution spraying in 1 minute. For household needs, it is recommended to take a paint sprayer with a flow rate of at least 0.8 l / min.
When choosing a spray gun, it is important to pay attention to its weight. When using too heavy devices, the master will quickly get tired and spend time on rest. The most convenient to use devices, the weight of which does not exceed 2 kilograms.
How to paint correctly?
The quality of the staining depends on many factors. First of all, it is affected by the level of surface preparation and the correct application of the pigment.
Works include removal of old-facing materials, dismantling of putty if necessary. If the previous layer is held securely, you can leave it. Any irregularities on the ceiling and wall surfaces should be eliminated. For this purpose, use putty. The solution is applied with a spatula. If you need to apply several layers, it is important to wait until the previous one is completely dry – this will take about 24 hours.
Before applying the paint sprayer, make sure that the surfaces are perfectly smooth. If roughness, protrusions, and other defects are detected, they should be rubbed with sandpaper.
Prepared dried surfaces are recommended to be primed to increase the degree of adhesion of the pigment to the base. Priming compositions can be applied with a brush, roller, or spray gun.
Before painting work, you need to properly dilute the”water emulsion”. Usually, to get a certain color, the masters mix white paint with a color of the desired shade.
When breeding, it is recommended to observe the selected proportions, otherwise, the color may turn out uneven.
After preparing the surface, the pigment, and the spray gun, you can start painting. Before painting, it is recommended to check the spray gun by making a few preliminary “splashes” on cardboard or thick paper. When applying the composition, there should be no smudges and splashing. If necessary, you need to adjust the width of the torch.
When applying paint to the ceiling, keep the paint sprayer perpendicular to the base at a distance of 30 to 50 cm. To ensure a uniform coating, it is recommended to make smooth movements with the tool.
The approximate speed of the nozzle should be no more than 1m in 5s. You can not hold the spray funnel in one place – this will lead to a thickening of the layer, obtaining a more intense shade.
Professional painters recommend painting the surface in 3 layers. They should be applied alternately, waiting for each one to dry completely.
When re-coloring the wet layer, the pigment may lie unevenly and soon peel off. In this case, the work will have to be repeated again.
Painting wall surfaces are similar to painting ceilings. Before the work, the old lining is also removed, plastering, leveling, sanding, priming is carried out. The painting should start from the far corners and move towards the front door. The torch should move from the ceiling to the floor.
It is recommended to apply at least 3 layers of pigment (the amount directly depends on the viscosity of the coloring composition). The coating with each new layer should be made across the previous one. If the first one was applied vertically, the second coloring will be vertical.
After using the equipment, it should be thoroughly washed and dried, and then put in a dry place for storage.
If there were drops of paint on the surface, the paint technology was broken – the sprayer moved too slowly. Excess paint is removed with a sponge.
If the layer is too thick, and there are detachments, apply putty to the problem areas. Next, we skin and ground the surface. We complete the correction of defects by applying two more layers of paint.
If there are obvious bumps on the coating, this is a consequence of dirty paintwork, that is, the preparatory measures were not carried out properly. To remove the defect, you will need to apply plaster to the problem areas with sandpaper. Medium – or fine-grained paper will do. Competent work with the spray gun allows you to achieve coloring results that are not inferior to the work of professional painters. The main thing, in this case, is accuracy and strict adherence to simple instructions.
