Decor elements

The paint for the gate should be selected not only taking into account the individual wishes of the owner. Main criterion- compliance with all existing quality standards.

One of the main selection criteria is high quality

The qualities of the paint must allow it to withstand all atmospheric surges, as well as exposure sun rays, hail, rain and snow.

How to choose paint

The modern market offers great amount paintwork materials.

Oil enamel has good performance and has high wear resistance

The best paints are sold in specialized hardware stores.

The main types of paint are presented in the plate:

View	Description
Molotkovaya	The most popular option. The main advantage is resistance to corrosion and other negative processes. Suitable for both outdoor and interior decoration. The composition of the paint is enriched with metal and silicone resin pigments. Resistance to negative natural factors is ensured precisely thanks to pigments.
oily	Based on drying oil. Designed for outdoor work. The main plus is the democratic cost. It is used infrequently, due to poor resistance to moisture. A few heavy rains can Negative influence to the appearance of the structure.
Alkyd	The environment has little effect on the paint. One of the undoubted advantages is the presence of high adhesion with the coating. Unfortunately, enamel is toxic. Working with her, you need to protect as much as possible Airways.
Acrylic	The most popular composition, actively used for interior decoration. Not suitable for outdoor work due to sensitivity to temperature fluctuations. After a certain time, the painted gates lose their attractiveness.

Why choose hammer paint

How to paint metal gate on the street? The ideal choice is hammer or blacksmith paint. The coating is highly durable.

Initially, it was used to decorate equipment in laboratories and factories, which was later intended for use in adverse weather conditions.

The main advantage is durability, as well as the absence of harmful impurities.

Over time, designers drew attention to the specific "shagreen" structure of the paint. Today it is used almost everywhere.

The main advantages include:

magnificent decorative properties. The color palette is quite rich. The painted surface is resistant to the effects of the scorching sun and will never fade;
no temperature vagaries have a detrimental effect on the paint;
when the composition dries, there are no toxic fumes. Against this background, it is allowed to use the remains for painting interior items;
the composition is perfect for painting a rusty coating. Pre-processing is not needed;
the composition has excellent mechanical strength;
the paint dries very quickly;
moisture resistance. A high-quality composition is able to protect the metal from corrosion for 8-10 years;
unique texture. If defects are formed, they can be easily retouched. Tinting will not be evident.

Note! With dirt and dust repellency, the paint provides surfaces with a clean “glossy” look in all conditions.

Main cons:

undemocratic price. Given the high consumption, painting can come out "for a pretty penny";
fast adhesion to the surface. This is both a plus and a minus at the same time. The bad news is that paint drops are difficult to remove even with very strong solvents. If you are not lucky to get something dirty in the paint, you will have to tinker for a long time before bringing it down;
the density of the enamel does not allow charging it into the spray gun;
corrosion that has appeared in unpainted areas quickly affects the main area.

Hammerite paint is the perfect choice

Enamel types:

View	What is it	Description
Hammerite	Unique composition 2 in 1. Production - Great Britain.	Expensive composition, practically without flaws. Apply directly to rust. Lasts for decades.
ML-165	The base is styrene-alkyd.	The best qualities are adhesion and resistance to heat (up to +125 degrees). Xylene is used for dissolution. Applies to all types of coatings.
NC-221	Nitroenamel.	The features are mostly decorative. Rather than protective. Not suitable for application on rust. It can be used both inside and outside the house at the same time. Temperature resistance is average.
AP-1323	Epoxy enamel (primer + paint)	A unique composition that allows you to paint any surface. You can work with rust. Removed with Thinner 667. Grade 648 can also be used.

Important! Blacksmith enamel is applied only in calm, sunny weather.

At high humidity you may encounter various difficulties. Perhaps the paint will not go well, and there will be a need for repainting.

Primer for painting

Paint for iron gates involves pre-treatment of the surface with a primer. This helps to increase the quality of adhesion and improve external characteristics. The nature of the primer must fully match the nature of the paint used.

Priming is the most important step before painting

What is primer used for? It contains special substances that transform chemical composition rust. The metal retains its properties longer and oxidizes more slowly. Correct use primer allows you to make the service life significantly longer.

How the material is applied

You may need the following to work:

selected material;
solvent;
primer;
brushes (sizes must be different);
roller;
sandpaper.

The whole process includes the following steps:

Holding preparatory work.
Elimination of defects (rust, dirt, grease).
Applying a primer.
Coloring gates (garage and "home").

How to properly prepare the surface

How beautiful to paint the gate? First you need to prepare the coating.

All steps look like this:

Coating cleaning. If there is old paint on it, it must be carefully removed. This can be done "armed" with a metal brush. You can also use a grinder. It must be equipped with a special nozzle so as not to damage the surface. You can also use a building hair dryer. To special wash it is advisable not to resort in view of its strong toxicity. There is a possibility of being poisoned by its vapors.

For sanding, fine-grained sandpaper is used.

Grinding. Fine-grained sandpaper is used. This ensures maximum adhesion of the coated enamel.
Degreasing. A strong solvent is used. When processing the gate, you need to cover the entire surface. Particular attention should be paid to hard-to-reach areas.
Padding.
Washing. Removes dust and dirt that has accumulated as a result of the operation of the gate, as well as after the previous stages. Recommended use garden hose, special detergent and sponges.

How the primer is applied

Before painting the gates of the house and garage, a primer must be applied. The steps are:

"Arm" with a roller or brush. Remove remaining flaws from the surface with a rust converter. When this composition dries, a whitish coating forms. It should be removed with a rag.
Using masking tape, carefully glue all the elements that are not intended for exposure to the primer. Sheds are pasted over, as well as a handle.
"Arm" with a comfortable brush. To speed up the process, it is recommended to use a roller. Apply a primer - first one layer, then two more. Each layer is applied only when the previous one is completely dry.

Important! The primer is applied at least 10 hours after washing the surface. This time is required for complete evaporation of moisture.

How the surface is painted

Painting the gate with your own hands involves the use of a wide paint brush. You can also use a roller or spray gun. If the second option is chosen, it is recommended to protect adjacent surfaces from paint as much as possible.

The stages of work look like this:

Painting starts at the top. You need to move down carefully, gradually, slowly. This is necessary in order to avoid the occurrence of smudges.
Parallel layers should overlap each other. This will help to achieve the uniformity of the enamel after it dries. There will be no abrupt transitions.
After painting the surface, you should take a few steps back and carefully inspect the gate. It is better to do this after the enamel has dried. So you can see the missing sections and correct the error in a timely manner.
Particular emphasis should be placed on staining the corners and edges. These are quite difficult areas, so you should use a contour brush to process them.
After a day, brush through the gate again. The optimal number of layers is 3. Depending on the weather conditions, this will help increase the service life of the product by 6-8 years.
The optimum temperature for work is 10-20 degrees Celsius. If this requirement is not met, problems may arise with the drying of the enamel. Smudges and blisters may also form. The color may become uneven.

Painting gates at home with hammer or blacksmith paint involves the use of:

brushes with natural bristles;
short pile roller;
aerosol can;
airless sprayer.

Each of these tools has its own benefits.

Working with blacksmith material

The gate is painted like this:

If a brush is used, then 2 layers of material are applied first. They must be thick enough. It is necessary to carefully paint over the grooves and edges. This will help protect the gate from the spread of corrosion.
Roller work involves applying enamel in 2-3 layers. When the paint is applied for the first time, it needs to be thinned a little. For 9-10 parts of enamel, 1 part of any suitable solvent. Then dilute the material is not required. Coloring begins with the study of corners and other areas with complex relief. Then you should move on to flat zones.
The aerosol is applied in 3-4 layers. They should be as thin as possible. Shake the bottle thoroughly before starting work. According to experienced craftsmen, this should be done within 3 minutes. The optimal distance for spraying paint is 150-200 mm. When the first layer dries, you will need to wait up to 3 minutes, then apply the next layers. The interval between them is 15-20 minutes.
If the paint is applied with a sprayer, it should be diluted with a solvent (proportions - 9 to 1). To obtain a homogeneous emulsion, the sprayer is well shaken.

Important! Most of all blacksmith's enamel "loves" the roller. They are well worked out absolutely everything, even the most problematic areas.

Conclusion

Paint fading will be less noticeable if you use more bright hues. If a darker shade has already been chosen, then in order for the gate to always have a “marketable” appearance, it is necessary to update them at least 2 times a year.

You can also install roller blinds - this helps to increase the wear resistance of the paint.

How to paint the gate if you ordered an unfinished structure from the manufacturer or decided to renew the corroded and peeling leaves damaged by corrosion? In the first case, everything is simple. It is enough to remove dust and pre-apply a layer of primer.

Photo No. 1: the procedure for painting the gate with a spray gun

We will talk in more detail about the re-staining of metal doors. From the article you will learn:

how to clean and prime the surface;
pick up paint;
apply a pattern to the gate by airbrushing.

Preparatory work

As we have already said, you need to start work by cleaning the surface from contamination. Choose a method based on the state of the material and budget. Unfortunately, if the metal is rusted to holes, no measures will save it. You will have to completely replace the sashes, this is an excellent reason to buy sliding gates - comfortable, modern, practical.

Surface cleaning

Since the finish coat will lie evenly only on a clean, fat-free surface, you will need to first remove the traces:

old paint;
oils and rust;
dirt and grease.

Budget cleaning method

To inexpensively remove old paint and dirt, you will need:

conventional spray gun;
metal brush;
sandpaper № 60;
white spirit or gasoline;
rag.

You will spend 8-12 hours manually cleaning the sashes. Advantage - in the minimum expenses. The procedure is as follows.

Wash the gate with a stiff brush. Let the metal dry.
Remove old peeling paint with a wire brush.
Sand the unevenness of the remaining coating with sandpaper.
Degrease the surface with gasoline or white spirit.

Important! It is required to clean from rust and traces of old paint not only the sash, but also all fasteners and locking elements, as well as the frame.

Mechanized cleaning of metal from rust

You can also paint iron gates after a simpler, mechanized cleaning method. You will need one of the following tools to work.

Photo #2: for mechanical cleaning old paint use metal brushes

Screwdriver with brush head. Easily copes with the task of removing old paint and traces of corrosion. The downside of the tool is that it runs on battery power. The screwdriver is quickly discharged, you will have to wait until the next start.
Grinder. Great alternative to sandpaper. The cost of such a tool is small - from 2000 rubles. The equipment is mains operated.
Bulgarian with a metal brush. Brass nozzles in the form of brushes are suitable for removing old paint. If we are talking about heavy dirt, pick up a brush with interwoven threads. Work with gloves and a mask.
Sandblasting. The most expensive and difficult cleaning option. To remove dirt and traces of the old coating, the gate is removed from the hinges. If you apply a layer of paint according to the technology on a previously cleaned surface, it will last up to 6 years.

Chemical cleaning

As a rule, separate chemical cleaning is not used. And indeed, in order to make beautiful gates for a summer residence or a country house, it is better to play it safe and remove a layer of old paint before exposure to the sashes with a reagent. So you will achieve maximum adhesion of paint to metal.

The ideal composition for removing rust is Hammerite paint and its analogues. Before applying, degrease the surface with white spirit and wash the sashes with acetone. Checking whether the metal is well degreased is simple: attach thin paper to the sash. If the fat spot does not appear on the sheet, proceed to staining.

Rust neutralizer

Now we will describe how to use a chemical wash before finishing the product.

Photo No. 3: rust neutralizer "Ferum-3" (Ukraine)

Apply the reagent to the surface cleaned with a wire brush. Use a wash with a gel-like consistency - it has the best covering power.
Cover the sashes plastic wrap- created Greenhouse effect speed up the process of paint removal.
Wait half an hour and remove the old coating with a spatula. Reuse the reagent if necessary.

The choice of paint and primer for the gate

Now we will tell you which primer is better to use and what paint to paint the gate with. It is important that the finish coat meets the following requirements:

good covering ability;
enhanced adhesion to metal;
the absence of components that oxidize iron;
high moisture resistance;
high rate of elasticity;
strength to mechanical stress.

Several types of paints for metal on the market meet these requirements.

Silicone enamel. Differs in high strength properties and elasticity. Moisture resistant. Adheres well to metal. All silicon-based organic enamels have anti-corrosion properties.
Alkyd enamel. Elastic and resistant. Suitable for exterior finish. Comes in a wide range color solutions.
Hammer paint. It is convenient because the coating does not need to be cleaned and primed before application. Provides excellent water and dirt repellency. It is applied from a spray gun under pressure.
Acrylic enamel. With its help, you can beautifully paint the gate of any type - swing, sectional, retractable. Withstands large temperature fluctuations, is not afraid of exposure to moisture and chemicals, and is resistant to atmospheric phenomena.

Popular paint brands

Now consider the most popular brands of coloring compositions for metal.

Metal primer

As you remember, before applying the paint, you will need another layer of primer, which will protect the surface from corrosion and provide better adhesion of the finish coating to the metal. To work you can use:

ship minium;
silver coin;
phosphating primer VL-02;
minium metal;
primer for metal GF-021.

Use a sprayer to apply primer evenly. After that, you can proceed to finishing.

Color selection

Since everyone has different tastes, the shade of the future gate depends only on the preferences of the owner of the garage. The most popular are green, burgundy, brick and blue colors. For ease of choice, we place a palette of shades.

Photo No. 7: a palette of paints for metal

Staining tools

It is better to paint the gate using:

spray gun - allows you to apply the coating in an even layer, without streaks;
roller - reduces the time of work, but leaves strips that have to be rolled several times;
brushes - increases paint consumption, complicates the procedure.

Sequence of work

We paint the metal gates sequentially from top to bottom, observing the following recommendations:

cover surfaces that do not need to be painted with masking tape or tape;
overlap one layer with another to hide transitions;
wait for the layer to dry and paint over the dotted missing areas;
paint over the hinges, grooves and latches with a thin brush;
apply the second coat after the first one is completely dry (recommended time is indicated on the paint package).

Important! Do not apply more paint than necessary. A thick layer reduces the strength properties of the material. The optimal number of layers is 2.

Temperature regime

Image No. 1: properties of enamels and varnishes

What happens if you ignore temperature advice? In 8 cases out of 10:

the paint will swell;
the color will turn out dull, with transitions;
there will be streaks and influxes.

How beautiful to paint the gate?

Beautifully paint the gate allows the method of airbrushing. To work, you need an airbrush - a device similar to a spray gun, but more functional.

Photo #8: This is what an airbrush looks like

Before drawing a picture, stock up on a sketch and paints. Where can I find a sketch? You can pick up an image on the Internet or design it yourself.

Sequence of work.

Transfer the contours of the future image according to the sketch. To do this, use paper templates.
To convey the depth of the picture, alternate light and dark shades of colors.
Work out the small details.
Cover the drawing with varnish to add shine and realism.

Examples of work performed by the airbrush method are presented below. Such drawings can be applied to retractable, swing and sectional garage doors.

For work, a simple spray gun and a paper stencil were used.

In the photo we see a metal gate painted black.

When choosing paint for metal products, many people are guided only by price and appearance, without thinking why there is such a variety of paints and varnishes on the shelves of hardware stores. But all of them are radically different from each other, and in order not to repaint the metal every year, you need to know the main selection criteria.

In this article we will tell you the best way to paint metal gates, and we will spend a small comparative review various colors.

Paint for metal can be of any company, the main criteria for its choice are its quality characteristics

Regardless of the brand of the manufacturer, price or brand of paint for metal, they all must have a certain set of qualities. So what indicators should you pay attention to when choosing?

There are quite a few important parameters, if there is no time or desire to delve into the issue, you can entrust the choice of paint and the painting itself to the master. He will pick up the right materials taking into account all the features.

If you want to choose a job yourself - Let's figure it out:

Adhesion to metal. Paints for different surfaces may not be suitable for other materials. Therefore, the inscription "paint on metal" must be present.
UV resistance. Since the topic of our article is painting iron gates, then resistance to sunlight should be the main selection criterion.
Wear resistance.
Water resistant. Modern paints perform not only a decorative function, but also a protective one.
Durability.
Ease of application. Some types of paints can only be applied in special conditions and only with the help complex equipment. We will not describe such materials, but it must be taken into account that different colors are applied in different ways.
Decorative element. If this criterion were not important, the question of how to paint the iron gate would not arise at all: we take a gray primer and apply it. Everything.

Beautiful gates of bright colors are now not uncommon

Advice! Regardless of which paint you have chosen, it is advisable to paint the gate with your own hands in a supine position so that there are no streaks on the surface.

As a rule, all these data, as well as detailed instructions by application, are indicated on the can of paint, but, unfortunately, this information is not always reliable. Some manufacturers intentionally write false data in order to sell their product more expensively.

Therefore, in this situation, it is better to give preference to a famous brand. Such manufacturers value their reputation and will not publish false information. Of course, the price of such paint will be slightly higher, but you get certain guarantees.

Oil based paints

Oil paints for metal work can also be used on other surfaces due to their good adhesion.

Oil paints were once the most popular material, but the point here is not the quality of the coating, but the fact that even 20-30 years ago, these paints simply had no alternative. Today they are used much less often, although they have a number of advantages, one of which, of course, is the democratic price.

Paint PF

One of the most common types of oil-based paints. She has excellent adhesion to metal, and she easily tolerates contact with water.

Despite this, PF paint is far from ideal, and here are just a few of its shortcomings:

Long drying, which even in summer can be calculated in several days.
Mandatory presence of a preliminary layer of primer.
Possible fading after 2-3 seasons.
With poor cleaning of the surface to be painted, it may begin to peel off after a few months after application.

This is far from full list, but even it is enough to consider other options.

Paint ML

Relatively new material oil based. In fact, this is a modified and improved version of the PF, and as a result with higher quality characteristics:

ML paint dries for a maximum of 24 hours at room temperature.
Does not fade in the sun.
Resistant to mechanical damage.

A significant disadvantage of this paint can be considered the need to apply primer before painting, and this is an additional cost of both time and finances.

Advice! Today on the shelves you can find ML paint, which says “rust enamel”, but experience shows that it is better to prime the surface, since the quality of the paint itself leaves much to be desired.

Specialty paints and nitro-based paints

Nitro enamels are paints based on chemical solvents, so they have a sharp, unpleasant odor. The main difference between nitro and oil paints is the drying speed. Some enamels completely dry in just a few minutes, others may take up to an hour.

And before proceeding to the description of the types of nitro enamels, we note that painting metal gates in closed and unventilated areas is strictly prohibited. Chemical components in the composition can cause significant harm to health, so you need to work with them either on the street or in a room equipped with a powerful forced exhaust.

NC

The most low-quality and short-lived paint from our entire review. We do not recommend working with her, but in fairness we could not help but mention her.

As a rule, NC paint is used for temporary painting of any products, or by unscrupulous manufacturers of metal structures. The coating will lose its appearance in a year, and after two years there will be no trace of it.

hammer paint

We see an example of what hammer paint looks like on metal surfaces.

Asking the question, metal gates than to paint, many prefer this particular option. In fact, hammer enamel is an ideal value for money.

It is maximally resistant to any kind of impact, and does not lose external data throughout its entire service life, and according to manufacturers, it is at least 25 years, but of course, subject to the rules for applying paint. Hammer enamel does not require a primer coat. It dissolves rust on its own and adheres strongly to the surface.

It is impossible not to mention the decorative qualities. After application, this paint begins to spread over the surface and forms small pits, resembling marks from a blacksmith's hammer, hence the name of this paint.

A certain difficulty may arise when applying hammer paint, so before getting down to business, we recommend that you watch the video in this article, which will help you clearly understand all the intricacies of the process.

Blacksmith paint WS-Plast

We deliberately left this paint for dessert, as it has no equal not only in our review, but also in the entire market of paints and varnishes. Needless to say, the price of this paint is very high, but in fact, it is worth its money.

Such a coating is not afraid of any impact at all. Even a blow with a hammer on the surface will not leave a trace on it.

Important! For blacksmith paint, a mandatory primer of the same brand is required. If a primer from another manufacturer is used, the quality of the coating is not guaranteed.

By consistency, this paint resembles liquid rubber, and has a corresponding chemical smell. Drying time maximum two hours, even if sub-zero temperature environment.

The manufacturer guarantees the high quality of the coating for at least 50 years, but so much time has not passed since the appearance of this material, so no one knows the real service life yet.

And in conclusion

Summarizing all the above, we present a small comparison table to help you make your choice.

Note that all the paints in the table are in descending order of their prices, from the most expensive blacksmith's enamel to the cheapest NC paint:

Specifications	Paint brands
Specifications	blacksmith enamel	hammer paint	ML	PF	NC
Adhesion to metal	high	high	average	average	low
UV resistance	high	high	high	average	low
Resistance to mechanical damage	high	high	average	low	low
Durability	high	high	average	average	low
Water resistance	high	high	average	average	low
Ease of application	There are difficulties	There are difficulties	easily	easily	easily
Decorative qualities	high	high	high	high	low
Approximate drying time	No more than 2 hours	From one to three	Up to a day	From days to three	No more than an hour

In the photo we see examples of the variety of paints and their colors.

Often, when writing an article, it is difficult to give any advice or draw conclusions, but not in this case. In our review, there is a 100% leader - this is the paint for metal gates WS-Plast. There is also an outsider - NC paint, but it is important to remember that the quality of the finished coating largely depends on the master. Even the most quality paint can be applied so poorly that it will not last a year.

The process of painting metal gates

Why is it necessary to paint metal products and why do it at all? After all, it is a strong and hard-wearing material, and, for example, new metal garage doors are already painted. Is it just for beauty? Answering these questions is required to understand the actions to preserve metal products from corrosion.

Identification of the need for staining

Metal gates of a country house, both garage and entrance, are used daily, which is necessarily reflected in their canvas. However, they are installed outdoors. And on the metal structure located under open sky, temperature and humidity affect, eventually leading to corrosion of the product.

Rusted canvas gives the gate an unaesthetic appearance. This indicates not only the influence natural factors, but also about improper preparation surfaces for painting. Therefore, it is necessary to pay attention to the process of preparing and painting metal products.

The need for painting is determined visually. This is not only clearly visible rust, but also the presence of internal corrosion, which leads to the appearance of small bubbles on the surface and further flaking, as well as peeling of the paint. If the preparatory work is done with high quality, then the next painting will not be required soon. It will only be necessary to periodically tint, or rather, refresh.

Paint selection

The choice of paint for metal gates

When choosing a material for outdoor work, certain requirements should be followed. They are dictated by the need for a long period of preservation of the surface from external factors. Here are the properties that the selected paint and varnish products should have:

good adhesion to the surface (adhesion);
sufficient elasticity, since expansion and contraction are the response of metal products to temperature effects;
the presence of water-repellent properties;
possibility of use in a wide range of temperatures;
resistance to chemically active substances;
strength under mechanical stress.

When choosing a paint and varnish product, it is necessary to take into account all the points of this list. After all, iron gates are used in various conditions. They may be affected not only by temperature and moisture, but also by mechanical stress or accidental ingress of oils and other chemicals.

Knowing the requirements for paints for outdoor work, you can proceed directly to the choice. There is a wide variety on sale paint and varnish products, the value of which varies widely.

The most used types are as follows:

Nitro paint is quick-drying, which makes it easy to use. However, it peels off, and then, within six months, it peels off. Not recommended for use over other types of paints and varnishes.
Oil. Allows you to cover the product with a thick layer, but dries for a long time. Depending on the company that produces the goods, the drying process can last from a day to a week. For such a long time, small particles stick to the canvas, which reduces the attractiveness of this type of paint.
Alkyd enamel - universal, has good resistance to abrasion. There is a wide range of colors and a choice of textures - the usual glossy or matte. The durability of the painted surface is from 3 to 7 years. Drying time - within a day.
Acrylic enamel - well withstands sudden temperature changes and exposure to moisture, as well as aggressive substances, is elastic. Has been widely used.
Silicone enamel - has good adhesion, is durable and elastic. Particularly distinguished by heat resistance, anti-corrosion properties and low consumption during painting.

Choosing a coloring tool

Tool for painting metal surfaces

This is an important moment in the production of paint work. Required the right approach, both for preparatory work and for painting the gate. Which tool to choose independent process depending on specific conditions and circumstances. An important factor here is the professional level of the worker.

Roller, brush and spray gun - the tool you need to do the job. Paint only with a brush, ineffective due to the appearance of streaks on the working surface. The work will have to be done again. It is impossible to paint with a roller in corners and narrow places. Therefore, their combined use is recommended.

The spray gun can only be used by a person who has the skills to work with it. It requires not only a timely change in spray pressure, but also the knowledge of what viscosity the paint must have in order to paint the gate. Lack of skills will lead to strong streaks over the entire painted area.

Preparatory work

Removing old paint from the surface of the gate with an angle grinder

Preparation for painting the gate must be carried out in strict sequence. It is necessary to perform the following work steps:

Washing or cleaning from dirt. The removal of contaminants is carried out, as well as the washing off of other substances adhering to the canvas. The most thorough work can be done using a hose. Pay special attention to corners and hard-to-reach places.
Surface cleaning. At this stage, it is necessary to remove peeling paint from the canvas. If the layer of the previous coating is large, then it is necessary to remove the entire thickness of the old stains. Works can be carried out both with a brush for metal and with a building hair dryer. It is possible to use a grinder or a drill with a special nozzle - a “brush”.
Grinding. It is produced with fine-grained sandpaper, regardless of the way the work is done - manually or using a drill that has a special nozzle. The mechanized method speeds up the work. However, without the use of manual grinding is indispensable in hard-to-reach places.
Degreasing. It is carried out with a solvent after cleaning and grinding. It is important to process the entire surface without gaps, not forgetting about hard-to-reach areas. It depends on the quality of the coupling. further coatings with metal.

Of course, changes and additions to the order of work are possible. Some gate owners wash after stripping and grinding, using detergents. This allows you to save on degreasing agents. But it should be remembered that these works must be carried out very carefully, and detergents cannot replace the solvent.

Carrying out painting work

Spray painting gates

You can paint the most evenly with a spray gun. The work is done quickly and efficiently, with coloring of all hard-to-reach places. You should be careful not to get into the respiratory tract small drops of paint, which fly in the form of a suspension in the surrounding space when working with such a tool.

The most common way to paint is to use a roller to large areas and brush in hard-to-reach places. Fulfill painting work it is necessary from above, gradually falling down. Apply paint in parallel lines that overlap by a few centimeters.

After painting is completed, it is required to evaluate the integrity of the work. To do this, move back a few meters to identify gaps and other defects. Paint over the found areas with a brush.

If the color of the paint after drying turned out to be dull, then a second layer is required. Work is performed in the same sequence - from top to bottom. Multiple layers can be applied to achieve bright color painted surface.

How to paint a garage door beautifully, reliably and inexpensively

Iron is susceptible to corrosion, so regular painting of garage doors is essential. How to properly prepare the surface of the gate, and what resistant paint to choose? There are folk tricks that will help reduce costs and labor costs, as well as speed up the process of bringing the garage door in order.
