How to paint with a spray gun

Preparing the spray gun for work

Before you start painting with an airbrush, the device is refueled and configured.

When refueling the spray gun, you need to remember about the obligatory dilution of the paint and varnish composition. If enamel and latex compositions are chosen for coloring, due to their increased viscosity, more intensive dilution is recommended compared to water-based paint.

Filling the spray gun before work - pouring paint into the tool reservoir

You can check the degree of dilution of the paint. To do this, it is poured into a tank in a small amount. Next, the liquid flow, the spray flow and the width of the torch are set to the maximum. In an inconspicuous area, a small area of ​​\u200b\u200bthe surface is painted over with an airbrush.

If the paint is sprayed from the spray gun in large drops or hardly comes at all, it means that the dilution of the composition was insufficient. In this case, add 5% thinner to the paint and check again until the flow from the spray gun begins to spray in a uniform stream of tiny droplets.

1. Spray gun setup.

• First you need to adjust the flow of fluid and air in the device; for this, the spray gun is suspended vertically above cardboard or newspaper;
• Then you need to press the spray trigger and hold until streaks appear on the paint spot;
• Next, the settings of the device are adjusted and the air nozzle of the spray gun is rotated until a stream of paint is formed in the form of a fan;
• It takes a little practice to strip the cardboard in all directions;
• To obtain a uniform coverage of the paint, the gun is moved over the cardboard at the same speed and at a uniform distance from it.

There is no need for better now. Now such a metal foil is sold for all kinds of tinsmiths who wrap their products around it for tightness and strength. It is shiny like a mirror and sticky on one side. You wind it on the pipe and it immediately becomes shiny like a mirror and paint nge ngado.KU me kuzhe eight years as wrapped. True, then they were not on sale and I got a Japanese one. And now they are full of any width. Usually they are sold in building supply stores where paints, brushes, vaalki, etc. Just do not try to paint batteries and hot pipes with silver. It reflects 60 percent of the heat inside the battery and pipes.

Paint with paint until the pipe is warm!

Laceka:

Heat-resistant paint… technology as for any pipes…. A good decorating store can give you a bunch of good advice about this….

Ilya:

In general, there are special heat-resistant paints. But you don’t need such paint, you only need a condition under which, during the drying of the pipe in the bathroom, the condition of the absence of moisture will be met (so that condensation does not accumulate on the freshly painted pipe and spoil the liquid paint). I remember when we were schoolchildren with friends, lived in the basement. So we painted the pipes with black paint there. The paint with which artists paint, we found it in the garbage. It turned out great, although the pipes were hot. I never thought that this paint is heat resistant ...

Lambrusco Grapes are:

It is necessary to paint at night, when there is no analysis of water and the pipe has warmed up a little. Wipe dry with a rag with acetone or better with alcohol and immediately wipe with Autophosphate (if the pipe is completely unpainted). After an hour, the tube will turn grey-white and slightly sticky. And it is best to paint with water-based latex primer-enamel “On Rust”, if you choose the color. If you don’t pick it up, then use any quick-drying enamel on it.

Types of spray guns

Modern manufacturers offer their customers a huge selection of tools. These include manual spray guns, electric and pneumatic. Manual is considered the cheapest, but it is intended only for water-based paints. The speed of the device allows you to paint about 200 square meters of the plane in an hour. It can work with the help of mechanical action, or by a compressor.

Electrical appliances are mains powered. Their advantages are that the device is light in weight, compact in size and not very expensive, unlike a pneumatic device. An electrical appliance does not require a compressor.

Pneumatic spray gun is a professional tool, as it works with any composition or mixture at high speed.

If the device is needed for a long time, then you need to pay special attention to the material of the outer case. Proven brass, aluminum and stainless steel housings

The material of the paint tank can be of two types: metal or nylon. In the first option, the advantages include a long service life and ease of cleaning, and in the second, transparency and the ability to constantly see how much paint is left.

Which spray gun to choose for painting can be suggested by specialized sellers in hardware stores, or craftsmen who work with these devices all the time. Working with an airbrush, whatever it is, will be noticeably better and faster than with a conventional roller. Many masters choose to use an electric tool, as it is much more convenient than a manual one.

According to the type of spraying, the following spray guns are distinguished:

• Airless;
• Pneumatic;
• Combined.

The first and third types do not produce a very high-quality coating when compared with a pneumatic spray gun. The choice of spray gun depends on many factors. If there is a lot of work or the device is needed more than once, then from the very beginning you should purchase a good tool that will not break after the first day of work.

How this or that construction tool works can be found in the instruction manual for the device.You need to set up the tool after filling the tank with paint.

On the video: the correct adjustment of the spray gun.

Painting walls with a spray gun

Before starting work, check the operation of the sprayer. Pour the composition into the container to the recommended mark, then bleed the air onto an old board or newspaper. At the start from the nozzle, a large ejection of paint can occur, so you need to first “pick up” the desired spray level so that there are no large splashes. As soon as the paint begins to spray evenly, you can proceed to painting on the wall itself.

Divide the work surface into squares about a meter by a meter - at arm's length. Paint your conditional squares first transversely, and then vertically, wavy movements are not allowed. First, process the upper area of ​​\u200b\u200bthe walls, then the lower plane. If you plan to repair the ceiling, then you need to paint it first.

The optimal distance of the spray gun from the surface is 30-40 cm (depending on the type and power of the device). Try to keep the nozzle as perpendicular as possible to the surface to be painted. Move the spray gun in fairly fast, but at the same time smooth movements at a speed of about 5-6 seconds. per running metre. Do not linger in one place, otherwise there will be influxes and drops that will flow down. If there is excess paint in the form of drops, then they must be carefully removed with a sponge, and an additional layer of paint and varnish should be applied on top.

Try to control the level of paint in the container and top it up in a timely manner. Otherwise, air may be sucked in, the paint layer will lie unevenly.

It is recommended to paint with water-based paint in three layers. At the same time, apply each subsequent layer after the final drying of the previous layer. During drying, do not allow drafts in the room and ultraviolet radiation on the surface to be painted.

  REPAIR AND FINISHING

Coloring technology

The painting steps include all the same steps as for regular wall painting. Before starting work, it is necessary to prepare the walls with high quality, that is, clean them of construction debris and dust, putty with a special composition, if there are obvious and minor defects, and prime them. After the primer has dried, you can start working with the device.

In order not to break the paint sprayer, the already diluted paint must be filtered from large and small clots. You can use regular fabric for this. This technology will not take a long period of time and effort.

All large furniture can be covered with plastic wrap, securing the edges with construction tape.

How to use the spray gun, you can learn from the instructions that should come with it.

The distance that should be between the wall and the device is approximately 40 centimeters. The jet must be directed perpendicular to the plane. It is not recommended to press the spray trigger just before the surface to be painted. This may result in uneven application. Move the device at the same speed and approximately the same distance from the wall. On vertical planes, a mandatory condition is the overlapping of the edges of the applied strips.

If the conditions of technology are violated, there may be irreversible consequences. They can be drops, uneven coverage and bumps. With uneven coverage, thicker areas may begin to flake off over time. Everything can be fixed, it will no longer make the wall look perfect.

You can see unpainted areas if you place side lighting next to the plane.

How to paint with an electric spray gun

To get the best possible result, you should prepare the walls and ceiling. Remove all debris, dust and those fragments of old plaster from their surface that can be peeled off with a spatula. Then all cracks and irregularities should be puttied, and after the putty has dried, cover the entire working surface with a primer. Take out furniture or cover with polyethylene.

When working with a sprayer indoors, care should be taken that there are no drafts, high humidity is not allowed. You can work outdoors only in calm, dry weather at air temperatures above zero.

An important point is the choice of paint. On the packaging, look for a note that the composition can be used in conjunction with the spray gun. If you do not find such an indication, do not use this material, as this may lead to breakage of the atomizer. Stir the paint thoroughly right in the jar and pour the required amount into another container. If the paint has stood for a long time, and lumps have appeared in it, it must be strained, as solid particles can clog the siphon tube.

At the next stage, pour the coloring composition into the device reservoir, filling it to two-thirds of the volume. Check if the gun is set correctly by spraying paint onto newspaper. All models of electric sprayers have three settings:

1. The intensity of the total air supply. It allows you to balance the consumption of paint and the form of its overlay. If moderate flow is required, the adjusting screw must be screwed down.
2. The flow of air entering the side jets is separately regulated. The surface area simultaneously covered by a jet of paint depends on this indicator: the stronger the air supply, the larger the area.
3. The speed of the air flow supplied in the center determines the consumption of paint. A separate screw is provided for its adjustment.

Attention! Before starting work, be sure to wear a respirator, goggles and overalls to protect the skin and respiratory organs from ingress of paint particles.

Progress

Observe the distance from the nozzle of the device to the working surface: it should be 15–20 cm. If this distance is less, then streaks will inevitably occur, and with a large distance, part of the paintwork material will evaporate. For uniform staining, hold the tool strictly perpendicular to the work surface. Try to move the sprayer without jerks, accelerations and decelerations - the speed should be the same all the time.

If you have to paint a wall, start at the top and work your way horizontally and down, making sure that each subsequent strip overlaps the previous one with an edge. To obtain the perfect result, the ceiling and walls are recommended to be painted in three layers.

The spray gun is suitable for painting furniture and any wooden products. The wood is painted along the wood fibers: this technique allows you to preserve the natural pattern of the material.

Spray gun application

The airbrush is a professional painting equipment that is used in the widest range of painting works. With its help, furniture, cars and yachts, facades of houses, walls and ceilings in the interior, doors and windows, ceramic products, plastic and much more are painted.

Using an airbrush as a tool for painting wooden furniture

The spray gun is filled with paint before work. When leaving the device, the paint is sprayed under high pressure in the form of tiny drops. The technology of the spray gun can be airless, combined and pneumatic (manual). The latter option is most suitable for beginner painters, although such a device is more expensive.

Remove rust from radiator

There are several ways to remove rust from the metal surface of a radiator.

The simplest one is mechanical, that is, we take a battery, take metal brushes and sandpaper and clean off all rust and a layer of past paint.

(Of course, the method is very long and difficult, but the most effective). You can also use the sandblasting method.

But, sometimes there are cases when the mechanical method cannot be used when we use mechanical compounds:

• We prepare a solution (500 ml of water, 105 g of ammonium, 100 caustic soda, 400 g of 40% formalin, then add another 500 ml of water), add 10% sulfuric or hydrochloric acid (100 to 3) to this solution. The detail is needed, first of all, degrease (for example, with gasoline) and allow to dry, then the rusty parts must be dipped in the resulting solution for 20-30 minutes, then rinsed thoroughly with hot water.
• Use tin chloride (dip rusty parts into it) then rinse and let dry.
• Fish oil (it is applied to the problem area and left for several aces).
• If there is little rust, then you can moisten the cotton wool with kerosene and wipe off the rust with it.
• Remove rust with machine oil and charcoal.

Home remedies (using what you have on hand):

• Vinegar + citric acid (1:1) and apply to the areas, leave for a couple of hours.
• Baking soda (mix with water until a thick slurry) and apply to areas for 20 minutes, then wipe off with a wire brush (it is possible to repeat the procedure).
• Coca-Cola (dip parts of the battery into Coca-Cola and leave for a while).
• Ketchup. Apply ketchup or tomato paste to the rust stain, leave for 10 minutes, then wipe dry.
• Foil (using it, you need to scrub the rust from the radiator).

Paint for radiators

The choice of paint is a very important aspect, because the final result will depend on the choice.

First of all, the paint must:

• Withstand high temperatures (at least 100°C);
• Have resistance to mechanical stress;
• Have protection from aggressive environment;
• Don't be toxic.

On sale there are such types of paints:

acrylic enamels. They are produced with organic solvents, therefore, when the paint dries, they emit a characteristic smell of the solvent. When dried, the surface is glossy with a sheen.

Advantages:

• High service life;
• Colors retain brightness and do not fade;
• Dries quickly;
• There are no cracks and "wrinkles" on the surface;
• Only water is needed to clean the brushes;
• Low price (compared to oil);
• Can be used in rooms with high humidity

Flaws:

High difficulty in removing acrylic paint from the surface.

Alkyd paints. The coating is highly resistant to high temperatures. On the market and in specialized stores there is a fairly large selection of this paint in different colors. But when dried and at high temperatures, this paint emits an unpleasant odor.

Advantages:

• durable;
• elastic;
• Dries quickly;
• Do not lose brightness;
• Will not crack or shrink when dry.

Flaws:

• flammable;
• They are afraid of alkalis.

Water-dispersion paints. It is considered the best choice, as this type of paint does not have the standard unpleasant odor and also dries much faster.

But pay attention to the packaging, the packaging must be marked "for painting heating batteries and pipes." Advantages:

Advantages:

Cheaper than acrylic paint.

Flaws:

Less resistant to moisture, mechanical damage.

To date, the best paint for radiators can be safely considered acrylic, it has a lot of advantages, at a fairly low price.

Preparing the radiator for painting

Sequencing:

1. We clean the surface from dust and dirt.
2. Wash off old paint.
3. Then the surface is sanded with sandpaper and degreased.
4. An anti-corrosion primer is applied to the cleaned surface.

There are paints in stores that already contain a primer, they are usually applied to the surface without preliminary work (but you need to clean and degrease).

Painting process:

1. Turn off the heating (if possible, if not then at least turn off the hot water).
2. Choose paint;
3. Cover the floor (put paper, wallpaper or fabric);
4. Apply paint from top to bottom;
5. First, internal floors, then external ones;
6. Wait for the first layer to dry;
7. Apply a second layer.

With careful priming and high-quality painting, you can forget about rust spots on batteries for a long time and admire your bright batteries again.

But if you are not satisfied with the simple battery design, you can improve it by reading THIS ARTICLE on how to decorate the battery with your own hands.

Painting technology

Gas communications are painted according to the rules for finishing metal products. The exception is the preliminary stage of stripping the old coating, during which it is forbidden to use heat.

The pipe is wrapped in a rag soaked in a cleaning agent and after 10-20 minutes the paint is removed with a spatula. When cleaning the surface from dirt and rust, a metal brush is used. After degreasing with acetone or gasoline, the pipe is primed with an agent intended for application to rust.

In the production of such compounds, dyes are used, so the primer can be of different colors - from black to green.

To increase the strength, varnish is added to it. It prevents the penetration of moisture into the porous structure of the substance and adds shine to the entire structure. Materials are purchased based on the formula: 1 liter of varnish per 2 liters of ground liquid.

Before applying the product, the surface is wiped with burlap and primed directly on the rust. The solution is applied in 2 layers with a brush.

After 48 hours, they start painting, during which the paint is applied perpendicular to the pipe, avoiding smudges. The coating should be thick, so it is not recommended to dilute the dye. Painting is carried out in 2 stages with intermediate drying.

What is it for

Gas pipelines are a potential hazard due to possible gas leakage and therefore require color coding.

Anti-corrosion coating of the gas pipeline.

With a small length of communications and for external networks, continuous identification coloring is performed. Marking areas are located at the junctions, branches, inputs and outputs of production facilities. The corresponding marker is present in the painting of gas pipes passing through the ceilings and walls of buildings.

In addition to the signaling function, this finish provides anti-corrosion protection for metal surfaces. For this purpose, heat-resistant oil and nitro-enamel paints are used, which are resistant to temperature changes and the influence of precipitation.

How to paint the walls and ceiling in the room with a spray gun

Painting large surfaces (walls or ceilings) is a rather laborious process, which is why it is so difficult to perform it at a high level. Using a special tool - an airbrush - will reduce the time for painting and get a neat, evenly painted surface.

In order for the result of painting to be just that, it is worth knowing how to paint with an airbrush correctly. We will tell you about the spray gun and the rules for working with it in more detail for those who plan to independently carry out such painting work.

The use of an airbrush for wall finishing allows you to get a uniformly painted surface.

Technology for painting iron pipes

Paint for hot pipes made of metal does not differ in its characteristics from the compositions used for polymeric surfaces. But the technology of work may be slightly different. Indeed, on old pipes and metal radiators there is always old paint that must be removed.It is better to choose technological methods for removing old paint. For example, use a grinder with brushes. In this case, the work will be completed much faster than grinding the radiator by hand.

When giving advice on painting radiators, one cannot but pay attention to safety precautions:

• use gloves at work;
• protect your eyes from paint;
• when working with a grinder, wear safety goggles.

Now you know whether it is possible to paint heating pipes during the heating season.

Types of paint

For painting communications on the street, anti-corrosion agents designed for metal products are used. This category also includes 3-in-1 primer-enamels, which, as a result of contact with iron oxides, form a protective film firmly adhered to the metal surface.

Such treatment can be used in cases where the corrosion thickness is not more than 0.1 mm. They produce formulations in the form of a solution, suspension and emulsion.

For interior work, any type of paint for metal is used, with the exception of vapor-permeable ones.

Outdoor gas pipelines

Popular means of painting an external gas pipeline include:

1. Alkyd enamel that can be applied to hot pipes. The composition forms a thin coating that is resistant to any weather conditions. Its service life is at least 5 years. It is necessary to work with alkyd mixtures carefully, since they are flammable and have a specific smell.
2. Polyurethane paint. It is distinguished by elasticity and good adhesion to the surface. The substance does not lose its qualities for 10-12 years.
3. 2-component epoxy - wear-resistant, but not elastic material.
4. Electrically conductive paint, represented by dispersions of aluminum or zinc powder in an organic varnish, provides 2-level corrosion protection.

Internal gas pipelines

Painted gas pipe in the interior of the kitchen.

When painting the gas pipeline in the apartment, both external and interior compositions are used. The main thing is that they do not create a vapor-permeable coating, since the purpose of painting in this case is to protect the metal pipe from the effects of steam and oxygen.

Fire-fighting dyes provide the necessary security for internal networks. During the heating process, these coatings turn into a carbonaceous foam with high thermal insulation properties that can withstand fire. An example is Polystil paint for painting gas pipes, which protects the surface for an hour.

Basic rules for painting walls and ceilings with an airbrush

1. When carrying out painting work indoors, it is necessary to take care of good ventilation and safety measures. During painting, poisonous vapor is released from the paint into the air. Therefore, when carrying out work, be sure to wear a respirator, goggles and gloves. Do not turn on appliances that have open flames. All windows and doors must be open.
2. The paint tank should be filled to a third or half of the volume. The paint should be pre-prepared. If the consistency is too thick, then the paint is diluted with a solvent, and then filtered through gauze or a sieve. If this is not done, then the sprayer will clog, and it will be impossible to continue painting the walls.
3. All work is carried out at a positive temperature. High humidity indoors or outdoors is unacceptable. Painting on the street should be done in calm weather.
4. The surface to be painted must be pre-primed.
5. Before starting work, test painting should be done on a drywall sheet or on a flat wall. If there are leaks, reduce the air flow. If the streaks are too large, then this means that the paint is diluted too much.
6. The tool spray should be kept at the same distance from the surface to be painted.The next layer is applied only after the previous layer has completely dried.
7. At the end of the work, the spray gun should be rinsed well and cleaned with a solvent. Otherwise, its use in the future will become impossible.

All the suggested tips are still related to the paint! I have another one. I'm talking about the heated towel rail in the bathroom. Remove old paint - you can use a knife or very conveniently with a gel to remove old paint. Then sand the pipe with sandpaper - first coarse, then finer. Then rub with Goya paste. Works for over 10 years!

mikhalych:

you have humidity and, as a result, condensation on the pipes, and it gouges any paint, think about a decent renovation of the bathroom, with the replacement of pipes and repair of ventilation

Paint preparation

Dilute the water-based paint in the required proportion with water in accordance with the recommendations of the instructions. Then mix the composition thoroughly with a construction mixer or a nozzle for a drill. If necessary, color the paint to the desired shade, while adding color should be done little by little, mixing everything very carefully, avoiding streaks. It should be remembered that in a diluted form, liquid paint always seems a little brighter than after drying on a painted surface.

Make sure that there are no clots, debris or dense lumps of paint in the paint composition, otherwise they may clog the spray gun in the future or leave defects on the wall. To avoid this, filter the finished paint through any dense fabric without hydrophobic impregnation or through 3-4 layers of gauze to clear the composition of all foreign particles.

How to prepare paint for an airbrush

Before moving on to how to paint the walls, it is necessary to briefly dwell on what kind of paint is needed for the spray gun and how to prepare it.

It is necessary to know:

1. Too thick and viscous paint will cause uneven distribution, increased drying time and wasted material. In addition, when painting inclined or vertical surfaces, the quality of work will significantly deteriorate due to smudges. This can only be corrected with a new stain. Also, minor irregularities, microcracks and roughness will not be filled.
2. Excessively liquid paint for the spray gun will require the imposition of additional layers to achieve the desired effect. In addition, this will entail a decrease in the strength of the coating and an increase in the time for painting the facades.

The following paint compositions are suitable for this type of painting equipment:

The choice of one or another paint for the spray gun depends on the material of the walls.For wood walls, it is better to choose an oil or acrylic solution, and for more modern building materials, acrylic, alkyd or water-based compositions.

The choice of thinner depends on the paint you choose. We recommend thinning the paint using special proprietary thinners recommended by paint manufacturers.
