What to do if you need to paint the fence, and the outside temperature is negative? A decade ago, the answer would have been obvious: wait for the warmth. Modern technologies offer coloring compositions for use in the cold.
To paint or not to paint
To begin with, we will determine whether it is possible to paint the fence in winter, in terms of the suitability of materials.
The metal does not change its structure when the climate and temperature change. The fact is that it does not absorb water, and this is its main advantage. Over time, a fence made of a profiled sheet can only heat up and stretch a little in a linear direction, and when it cools, return its shape. Compositions for metal painting are adapted to this quality - they form an elastic film on the surface.
Painting wooden fence in winter period not recommended. The fact is that moisture constantly accumulates between the fibers of the tree. At positive temperatures, there is a constant moisture exchange in the wood, in frost the water freezes, expanding the structure of the material, the applied layer of enamel will seal the ice, and when thawing, the water will repel the paint and the latter will go in bubbles. In addition, the process of active decay will begin.
Painting the tree is possible, but after the test: several strips of wide adhesive tape are glued to a clean area of \u200b\u200bthe fence. After a day or two, the result is assessed: if condensation has formed on the surface of the film or inside there is frost, then the painting will be meaningless. If no water falls out, the fence can be covered with a layer of enamel.
Features of work in the winter
Is it possible to paint a fence when sub-zero temperature - found out. The next question is how to carry out work at low temperatures. There are several basic rules:
- Use only those intended for work in winter conditions enamels. Mainly alkyd paints based on solvents that do not change their consistency in frost. Sellers regulate them as paints for metal, but use on wood surfaces is permitted.
- The surface to be painted must be dry.
- Metals must be degreased with acetone or isopropanol.
- It is not recommended to carry out works in the temperature range -5 ... + 50C. When high humidity condensation is likely to occur.
- The coloring composition must be necessarily warm (above 00C). If the structure is large and requires a long time to cover, it is recommended to put a bucket of paint in a container with warm water to maintain a comfortable consistency of the working composition.
- You can often hear advice: warm up the metal with a hairdryer before painting. It is worth remembering that the material has high heat transfer and instantly cools in the cold. Therefore, you need to paint with a hairdryer in your hands or leave this venture.
Ordinary enamels dry for a long time in frost - from 3 to 7 days. Remember this before applying the second coat. Special formulations dry from 1 hour.
Review of effective enamels for winter use
Exists a large number of specially designed coloring compositions for work with low temperatures... They differ from the usual ones:
- Do not freeze in the cold;
- Form an elastic layer even under extreme conditions;
- Suitable for wood and metal;
- Combine anti-corrosion, fire-prevention, antifungal (for wood) properties;
- Dries quickly compared to conventional formulations.
The main selection criterion is the temperature range of application. And the price, of course, matters.
We will look at the basic formulations suitable for painting simple structures.
SEVERON
Alp-Emal CJSC - large domestic manufacturer paint coatings, supplies the market with the most widely used composition SEVERON, it is used for painting large objects of national importance (oil pipelines, construction cranes, bridges, power lines, etc.).
The coating is fire-resistant, forms a slightly flammable film, resistant to high temperature + 150 ° C. The lower threshold of stability is -60 ° C.
Painting metal fence Severon enamel does not require additional priming, and two or three layers can be applied in one day.
Price - about 130 rubles / liter.
Priming enamel SEREROL
The product of the same Alp-Enamel plant is compatible with different materials, has similar characteristics:
The enamel does not require a primer, but the surface must be free from dirt and grease. The application is carried out with the usual devices - rollers, brushes. Skin contact should not be prolonged.
Price - about 160 rubles / liter.
ORTAMET
This winter-hardy compound is suitable for covering a rusted fence. It is applied at temperatures up to -15 ° C with any tools. The active base transforms corrosion spots into a reliable protective covering dark brown or black. Suitable for use on all metals. For effective application and to obtain an ideal effect, it is necessary to remove old peeling paint from the fence. Drying time "to touch" - 2-3 hours, layer polymerization - about a day under unfavorable conditions.
Price - about 140 rubles / liter.
WINTER
Special compound resistant to chemical reagents. This can be recommended in areas where roads are abundantly sprinkled with melting substances. If your fence is constantly in contact with treated snow, the outside of it can be winterized. The paint is expensive - about 230 rubles / liter.
Quick-drying rust enamel "ANTIKOR" winter
Universal enamel for metal, wood, concrete and stone.
The coating is resistant to absolute humidity and a wide temperature range from -60 to + 300 ° C.
Preparation of the base is carried out in the usual way: removal old paint, sanding, degreasing. Application is carried out with a roller, brush or spray gun. average price primer-enamel for rust "Antikor" - 190 rubles / liter.
Zinc-filled primer enamel "CITAN"
For a fence made of low carbon steel, this composition is suitable. The paint forms a matte protective film that prevents moisture penetration and hides defects on the metal surface.
Ground-enamel FESTPRO XC-7200 ®
There are silicon-containing, chemical-resistant and weather-resistant preparations for winter application, but they are intended for painting industrial objects that are constantly in contact with aggressive media. Such enamels are expensive and it is irrational to use them for fence.
Conclusion
Painting the fence in winter is possible, the main thing is to properly prepare the surface and choose the composition. The list of paints is not limited to the above list. Read the instructions, choosing the right composition, this is the main source that will provide information on the use and method of applying the drug to the surface.
Industrial and construction complexes in our country do not take breaks for the winter, which means that the paint and varnish industry must also meet similar requirements. Despite the fact that most enamels and varnishes require application at temperatures above 0 ° C, modern technologies allow the production of a range of materials suitable for coloring in the cold season.
Regardless of the material that is selected depending on the needs, the application itself at subzero temperatures has a number of features.
At first, important factor when painting in the cold season, surface preparation is. If metal is to be painted, then it must be thoroughly cleaned of condensation and ice. And since in most cases brushes and scrapers are impossible to handle thin layer ice, it is recommended to additionally warm up the surface with a torch gas burner.
Secondly, coloring at temperatures between -5 ° C and 5 ° C should be avoided, since it is in this temperature range that condensation and dew form on the metal surface. To avoid moisture condensation, the temperature of the surface to be painted must be at least 3 ° C above the dew point.
Thirdly, in winter, it is advisable to degrease metal surfaces with acetone or R-4 or R-5 solvents.
Fourthly, even if the manufacturer allows painting at temperatures below 0 ° C, such weather conditions cannot but affect the drying time of the coating - compared to the indicators specified in the quality certificate, it will increase by 2, or even 3 times.
Separately, mention should be made of the storage of enamel - regardless of its composition, it should be stored exclusively in a warm room, in the future, the painted surface and paint should be at the same temperature. If possible, the surface to be painted must be warmed up.
The choice of paint and varnish material also needs to be taken extremely seriously, because the final result depends on this choice - the durability and functionality of the resulting coating.
Paints and varnishes that can be painted at low temperatures:
Enamel KO-870 - heat-resistant anticorrosive enamel KO-870 is designed for protective painting of equipment and metal surfaces exposed to temperatures from -60 ° C to + 600 ° C during operation. Heat-resistant enamel has excellent resistance to aggressive media: oil products, salt solutions, mineral oils.
The enamel can be applied at temperatures as low as -30 ° C.
Facade KO-174 enamel - intended for protective and decorative painting of facades of buildings and structures (concrete, asbestos-cement, brick, plastered surfaces), as well as for anti-corrosion protection of metal surfaces operated in atmospheric conditions, including high humidity... It is applied at temperatures from -30 ° C to + 40 ° C.
Organosilicate composition OS-12-03 - enamel to protect metal structures from atmospheric corrosion, as well as corrosion in gaseous environments with a slightly aggressive degree of impact. Application temperature range from -30 ° С to + 40 ° С.
Primer-enamel XB-0278 - chemically resistant primer-enamel for painting metal surfaces with residues of scale and dense rust. Application temperature from -10 ° C to + 25 ° C.
Primer-enamel "Spetskor”- coating based on primer-enamel is resistant to UV rays, hydrophobic, has good vapor and air permeability, moisture resistance, frost resistance down to -60 ° C.
It is applied to the surface at an ambient temperature of at least minus 20 ° C
Enamel ХВ-124 - for painting primed metal surfaces, as well as wooden surfaces used in atmospheric conditions. The enamel is applied at temperatures from -10 ° to + 35 ° C.
Enamel ХВ-785- for protection in a complex multi-layer coating of pre-primed surfaces of equipment, metal structures, as well as concrete and reinforced concrete building structures, operated indoors, from the influence of aggressive gases, acids, solutions of salts and alkalis at a temperature not exceeding 60 ° C. The enamel is applied at temperatures from -10 ° to + 35 ° C.
Any work in the cold is not comfortable, and if possible, it is better to postpone metal painting and spend in the warm season. What to do if the winter cold has already come, but all the planned work has not been completed on time in the warm period, and metal constructionsoutside are not painted?
There is an opinion that it is impossible to paint on the street in winter, or it will not work, however, it is erroneous and irrelevant. To date, developed many paints and varnishesthat can be used in any weather.
For painting metal surfaces in winter you can. For their use, a temperature range of -20 to + 35 ° C is permissible. At the same time, the quality of the coating and ease of implementation painting works even the presence of moisture on the metal surface does not affect.
If it is not possible to postpone painting the metal until warming, several factors must be considered.
First of all, they should not contain ingredients that freeze at a temperature that does not drop to -20 ° C.
It is necessary to completely exclude the use of alkyd and other paints that increase viscosity at low temperatures.
To remove frost covering the metal, it is necessary to treat the metal surface with the fire of a gasoline or gas burner. It is not recommended to use brushes and scrapers, since after their use the surface is not completely cleaned.
It is important to degrease the surface with acetone or isopropanol before applying the primer.
When carrying out painting work in winter, a special frost-resistant primer is used to prime the metal surface, while it is necessary to select the composition for this type of metal.
The primer provides protection against corrosion and improves the adhesion of the topcoat.
If necessary, using a special brush, before starting work, the surface is thoroughly cleaned from loose rust and dirt that create irregularities.
Consumption of anticorrosive paints and varnishes for painting metal surfaces in winter is the same as in warm weather. All materials intended for application at low temperatures are fast drying. The finished coating does not react to precipitation within an hour after application. So, with an air humidity of 80-95% and a temperature of -15 ° C, the time for complete drying will be 2-3 hours.
The service life of the coating applied at low temperatures reaches 10 years, subject to painting technologies.
Should I paint the fence in winter?
What to do if the outside temperature is below 0 ° C and you need to paint a metal fence.
When the temperature changes, the metal does not change its structure, does not absorb water. At elevated temperatures, the fence from the leaf can stretch a little, and when it cools, it returns its shape. intended for painting metal, adapting after application, form an elastic film on the surface.
For painting metal fences in winter, enamels are used that are designed to work at low temperatures. Necessary properties have solvent-based alkyd paints that do not change consistency at low temperatures.
Metal paints can also be used to paint wooden surfaces.
Before painting, the surface of the metal fence is dried and degreased with special means.
For painting, not cold, but a warm coloring composition is used, having a temperature above 0 ° C.
If when painting large structures it takes a long time, then the container with paint is placed in warm water to maintain the desired consistency of the composition.
Special enamels designed for painting metal in winter dry from 1 to 3 hours, and ordinary ones - from 3 to 7 days.
Effective enamels, intended for use in winter, do not freeze in frost, are suitable as for metal and for wood, combine anti-corrosion, antifungal and fire-fighting properties, even in extreme weather conditions form an elastic coating layer, dries quickly compared to conventional dyes.
Paint a metal fence and other metal products winter is possible. The main thing is to choose the right surface for this. Each package of the product always contains information about the method of application.
I went to the seminar organized by the Publishing House "Origami" magazine "Cleaning. Coloring", held in St. Petersburg on November 14-15, 2011 under the title "The practice of applying paint coatings at subzero temperatures."
In addition to having listened to the information I am quite aware of about the types of corrosion and how to deal with it, about Wiwa painting equipment, which I will talk about later in the Equipment section, where the experience of working with many painting equipment has already been described, and showed a small master class on painting of corrugated board.
I also listened to a very interesting lecture by technologists from the Morozov Chemical Plant on applying paint at subzero temperatures.
Morozovsky Chemical Plant is the oldest Russian enamel manufacturer. It was he who began to produce heat-resistant enamels of all known types of KO and OS. I will talk about enamels too, but later, in the Materials section. I think it will be interesting.
I had a long-standing correspondence relationship with MHZ. 
It was very nice to meet you in real life. There is no doubt about their professional approach to AKZ. What are the trips of the chief technologist of the Moscow Chemical Plant Urvantseva G. to many objects, where they are painted with enamels, her constant consultations and technical supervision over the production of painting at the facilities. Great amount thank you reviews about MHZ.
So, back to the main topic of the seminar.
Paints can be applied at negative temperatures. To do this, the following conditions must be met:
1) Do not paint at a temperature of + -5 degrees. C. This is due to the formation of condensation, dew, on a metal surface. In general, this temperature is the worst for coloring with any paints.
2) The surface to be painted and the paint must be at the same temperature. Condensation will also occur when warm paint is sprayed onto a cold surface when materials of two different temperatures come into contact. Even if we all understand that airless painting occurs very quickly, nevertheless, condensation forms.
3) The question of how to paint concrete surfaces at negative temperatures requires additional consideration.
Of course, it was said a lot about the fact that it is possible to paint with OS and KO enamels produced by the Moscow Chemical Plant, up to -10 degrees C, without losing quality, but I did not have to work with them at such a temperature.
I had to work with enamels:
PF-115 and KhV-0278, at temperatures from -0 to -10 degrees. S. It was just cold to work further. He painted in a cold room, with paint that was stored there.
ХВ -174 in the open air at a temperature of 0, + 5 degrees. With a metal structure of the same temperature, paint stored at the same temperature.
PF-100 indoors at a temperature of -5, + 7 degrees C, which in the end was raised to +12 degrees C
As seen, temperature regime was not observed everywhere.
As a result:
Application: - the same as always.
Drying: XB 0278, 2-3 hours (same as always)
PF-100 - drying 2-3 days (according to the passport - a day)
PF - 115 drying from 7-10 days or more (according to the passport - a day)
ХВ -174, as always, drying for 2-3 hours.
Polymerization:XB 0278, 5-7 days (the same as always).
PF-100, 5 days.
PF - 115, not known. When we left the facility, it was still not dry 🙂
ХВ -174, drying 2-3 hours (same as always).
Exploitation:XB 0278 costs more than a year, without coating defects.
PF-100, no negative reviews, it is impossible to get into the painting territory
PF - 115, stood for half a year, in the fall it began to fly off like burdocks.
XB -174, stood for a year. Burdocks began to fly off.
It is worth noting that the enamels PF-100 and KhV-0278 are primer-enamels for rust. They have additional additives in their formula and have an order of magnitude different cost. Although I am skeptical about coatings such as primer-enamel for rust, they nevertheless performed the best under these conditions.
PF-115 on the basis of Russian SNIP is not recommended for painting metal structures used in industrial operating conditions. Therefore, the legality of the project for painting PF-115, metal structures is in great doubt. Even if the application conditions were observed at subzero temperatures, she behaved in the most delicate manner.
An example of painting XB-174, which in its plastic properties does not differ from XB-0278, showed non-compliance with technologies and the result was not long in coming.
Thus, from personal practical experience from my observations, I can confirm that a high-quality coating at negative temperatures can be made. The main thing is not to paint at + - 5 degrees. FROM.
