Type of Surface	Spray Gun Tips
Wood	Use a steady, sweeping motion. Start with a thin coat, let it dry, then apply a second coat. Use a fine spray for smooth surfaces and a wider spray for rough surfaces.
Metal	Ensure the surface is clean and rust-free. Use a primer designed for metal. Apply thin, even coats to prevent drips and runs. Hold the spray gun 6-8 inches away from the surface.
Walls	Mask off edges and cover nearby areas to avoid overspray. Use a wider spray pattern for large areas. Apply multiple thin coats instead of one thick coat for even coverage.
Ceilings	Use an extension on your spray gun for ease. Start from one corner and work your way across. Overlap each pass slightly to ensure even coverage. Be mindful of drips and fix them immediately.
Furniture	Disassemble parts if possible. Use a fine spray for detailed areas and a wider spray for larger surfaces. Apply thin coats to prevent buildup and achieve a smooth finish.

What types of spray guns are there: features of the tool and its types

Using a spray gun makes painting big surfaces—like walls, floors, or ceilings—quick and efficient. You can also apply paint in a thinner, more dimensional layer with this device. It enables the use of various materials, including acrylic, oil-based, and water-based.

The following categories of devices are distinguished based on design elements:

• Pneumatic – such manual devices include a tank, receiver and compressor. This element forces air into the atomizer. After which, under high pressure, it breaks the paint into small fragments and pushes it out of the nozzle. Due to this, it is possible to obtain a dye torch.
• Electric – these products include a built-in pump. It does not form small particles during operation. Therefore, the painted surface is not so ideal. However, such spray guns also have many advantages – they are distinguished by their compact size, light weight and affordable price.

Take note: The devices’ tank locations also vary. It may be side, bottom, or top.

Several manufacturers produce spray guns. The companies Bosch, Kalibr, Prorab, and SATA offer the best devices available. Additionally, you can use FIT or Energomash devices.

What to do with the spray gun before work

Spray guns must be set up before they are used to paint anything. Paint or varnish must be added to the tank before completing this step. Tightly closing the lid is crucial.

It is advised that you do the following in order to configure the device:

• Adjust air and paint flows. To do this, the tool must be suspended vertically and pointed at a sheet of newspaper.
• Press the trigger and wait for smudges to appear on the sheet.
• Adjust the sprayer and move the device in different directions to obtain an even layer.

Operating rules

How should I use a spray gun to paint correctly? It’s crucial to heed the main advice and consider the surface type if you want a decent outcome.

Basic techniques for painting simple surfaces

You must understand how a spray gun operates in order to paint surfaces correctly. Starting at the plane’s corner is where painting should start. The device needs to be moved from left to right, with a distance of 10 to 15 cm from the element’s edge. Applying the subsequent stripe lower than the preceding one is required. It should also cover it by half at the same time. Until the entire surface is painted, these steps must be repeated.

Painting and plastering of walls

The walls must be divided into sections in order to paint them. Painting must be done one at a time, 10 to 12 cm above one another. You can alter the nozzle size, pressure, or spray distance as necessary.

Crucial! The composition needs to be applied in two layers for best results. It is only possible to apply the second layer once the first has fully dried.

Textured plaster is applied with a cartouche gun. In this instance, the nozzles’ diameter ought to be between 6 and 8 mm. Spraying the material at a distance of 10–15 cm is recommended. When gypsum material is used, the spacer is shortened to 5–10 cm.

Painting the ceiling

The following guidelines must be followed when painting the ceiling:

• to apply a uniform layer, ensure a jet length of no more than 70 cm;
• the spray of paint should be applied perpendicular to the surface;
• the second layer is applied only after the first has dried;
• the surface must be painted in a circular motion.

Wood and plywood work

Wood is regarded as a material with a high degree of permeability and a fragile surface. When exposed to moisture, it degrades rapidly. Because of this, offering premium waterproofing is crucial.

Primer, varnish, or hydrophobic impregnation must be applied before painting furniture or other wooden goods. Outside wooden objects must be primed, impregnated, and prepared appropriately to ensure protection. Using oil paints is the best option.

Crucial! For heavy duty applications, a wood spray gun is recommended. Therefore, using such a device to paint a wall is much faster than using a brush.

Painting of metal products

Spray guns are frequently used to paint metal objects, such as automobile bodies. The surfaces must be appropriately prepared. The following actions are advised in order to accomplish this:

• clean the surface of dirt and old paint;
• treat the surface with a solvent;
• rinse with clean water;
• putty the damaged areas;
• apply primer.

Whenever metal surfaces are painted, bubbles and streaks frequently appear. For this reason, a lot of people are curious about the right way to use a spray gun to paint metal. To accomplish this, abide by these guidelines:

• turn off the device as rarely as possible;
• move the device slowly, without making sudden jerks;
• apply layers in parallel;
• paint elements from different sides;
• keep the interval.

Application of hammer paint

With the help of this material, you can simulate a hammered metal surface. The dye adheres to surfaces very well.

When using this kind of substance, you have to follow these guidelines:

• use a professional spray gun with a compressor;
• use large diameter nozzles;
• dilute the dye with solvent or xylene;
• paint the surface in 1 pass, applying overlapping stripes;
• make 1-3 layers.

For informational purposes only! The surface becomes resilient to damage and temperature changes once it has dried.

How to paint using a stencil

With the help of this technology, you can embellish surfaces with lovely patterns. Prior to painting, you must secure the stencil onto the surface. To accomplish this, complete the following tasks:

• apply paint to the area where the pattern is placed, setting the minimum flow rate;
• apply the dye in one quick motion;
• After the substance has set, carefully remove the stencil.

Any surface—wood, metal, or drywall—can be painted with a spray gun to create a polished, seamless finish. The fundamentals of using a spray gun will be covered in this article, along with tips on how to prepare the area, avoid common mistakes, and select the appropriate paint and spray gun type for each surface. Compared to conventional painting techniques, you’ll save time and effort by using these tips to achieve an even coat and a faultless finish.

Features of using an electric spray gun

An electric spray gun: how to use it? The following parameters need to be adjusted in order to get an even coating:

• intensity of total air supply;
• intensity of air supply to the side jets;
• air flow speed.

Crucial! Maintaining a distance of 15-20 cm is essential when working. Drips could occur if the distance is shorter.

Features of using a spray gun from a compressor

It is necessary to position the device straight in order to get an even coating. Open the paint supply between 10 and 15 centimeters away from the surface. If not, there’s a chance the surface will become unevenly colored. It is necessary to paint materials in layers. This is carried out left to right and top to bottom.

Cleaning the spray gun after use

In order to clean the spray gun, you must:

• disconnect the device from the compressor or network and remove any remaining paint;
• remove the tank and wash it;
• unscrew the air cap and lower it into the solvent for 10 minutes;
• carefully pull out the needle and clean the channels;
• clean the outer casing and assemble the device.

Possible problems when applying paint and solutions

The following issues could arise when using the device:

• smudges along the edges – their appearance is associated with a strong air flow;
• excessive drips – associated with an excessive amount of paint that passes through the nozzle;
• dusty coating – due to the increased viscosity of the dye.

Using a spray gun to paint provides a clean, polished look that is difficult to accomplish with brushes or rollers. You can achieve the best results and maximize your painting technique by being aware of the subtle differences between various surfaces. Whether you’re working with metal, wood, or walls, getting organized and selecting the appropriate tools is essential.

Different surface types call for different preparations. Wood must be primed and sanded in order for the paint to stick well and last a long time. To stop corrosion and guarantee a long-lasting finish, metal surfaces frequently require a rust-inhibiting primer. To achieve an even surface, walls—especially those with paint or wallpaper already on them—may need to be cleaned and patched.

Depending on the surface, different spray gun settings and paint types are also used. Larger nozzles may be needed for thicker paints, but thinner paints perform best with finer nozzles. Achieving an even coat free of overspray and drips can be facilitated by modifying the spray pattern and pressure in accordance with the surface texture.

It can be very beneficial to practice on a test surface first so you can refine your technique before taking on the larger project. Recall that accuracy and patience are essential. Any surface can be transformed into a flawless, new look with spray painting if it is carefully prepared and paid attention to detail.
