Painting area of 1 section of a cast iron radiator

High-quality painting assumes:

preliminary cleaning from dust, rust and dirt;
removal of all layers of old oil;
coating with a primer for metal, preferably heat-resistant;
painting in 2 layers gives the best quality and even surface (one layer can be slightly diluted with a solvent to save composition).

Many actions are easy to carry out with the tools at hand, including brushes for cleaning and washing. Old paint can be removed using different methods (you can do it in a complex way):

chemical;
mechanical (special attachments for the grinder and a universal tool);
thermal (building hair dryer, blowtorch);
by hand.

Advice! Use a metal brush to scrub the surface before applying the primer to remove loose particles that can then adhere to the brush or roller.

Old radiators after painting will last for at least a decade.

Not all paint is suitable for painting cast iron radiators. Only non-toxic heat-resistant interior enamels. They are sold in different forms - cans, cans, buckets. If you paint without a primer, you can degrease it with a solvent suitable for its chemical composition. Even if the enamel is "environmentally friendly", when painting the area of a cast-iron radiator MC-140 (another model), use:

respirator,
work gloves;
work clothes and footwear.

It is recommended to ventilate the room at every stage of processing, especially after the paint has set a little. All calculation data are adjusted for any modern model or old model. The area of the heated surface varies slightly for 1K60P-60x500 "Bas-relief", Standard-90, RD-90s, 2K60P-300, B-Z-140x300, MR-2KP140 "Beckard", etc. How to calculate the number of sections , on the "calculator" or through the program, decide on your own. There will be no big discrepancies.

The design of the MC-140 cast iron radiators.

Cast iron radiator consists of sections made of high quality cast iron, connected by ductile iron nipples.

Cast iron radiators are supplied coated with a primer or baked epoxy polyester enamel.

Preparatory actions

They provide for cleaning the surface from dirt and old paint. Preparation takes place as follows:

Wipe off dust with a damp cloth. You need to wipe it very well. There should be no dirt in the pits. To wipe hard-to-reach places, the rag is moved between the ribs and pulled back and forth.

sandpaper and file

A layer of primer is applied. Of course, it has to withstand high temperatures and match the type of paint. It will be better if the brand of both is the same.

It can be carried out with any type of composition. but on one condition: the solution must be resistant to high temperatures. Otherwise, the updated look will not last long.

The surface of the radiator is painted with a regular or curved brush. Of course, in the beginning, gloves are put on their hands and gauze, foam rubber or rags are placed next to it. They can be used to wipe off paint that has run down the handle of the brush.

The staining process is as follows:

Use a flexible brush to update the look of hard-to-reach places (they are located between the section pipes). In some parts, the brush will not touch the cast iron. Gauze folded into a tourniquet can save you. It is placed between the sections, paint is applied to the middle, and then the ends are pulled in turn. So, the paint will somehow fall on the alloy.
Paint the top and easily accessible places.
Always moving from top to bottom. It is better to apply the paint in several layers than one thick one.

Why calculations of paint consumption for radiators vary

Not everyone wants to get rid of old cast-iron batteries after modernizing an apartment. They are practical and reliable, and if the heating system is cleaned and the rusty pipes replaced, old radiators after painting will last for at least a decade.

Advice! Do not cover yellowed, in places crumbling and cracked layers of paint with a new coating. This should be done only after removing the old paint layers and opening the metal with a primer.

Calculations for paint consumption are complicated by the variety of models of heating devices, differing in many parameters:

mass (weight);
aesthetics (design);
format (dimensions of the section and the entire battery);
power (heat transfer);
the volume of the coolant (water);
connection method (side, bottom, diagonal), etc.

Improved design batteries may require more paint than conventional batteries

New models are also produced, imitating old cast-iron "accordions". They exactly imitate the general structure of classic heating equipment. They have an improved design with artistic molding or designer soldering and comfortable feet on the bottom for floor standing. They require a little more paint and primer, materials must be taken with a margin.

Methods for calculating the area of \ u200b \ u200bcoating paint

You can find the information you need about the area covered by paint in the technical description of the model. Usually, for domestic equipment, it is indicated as "heating area" or otherwise, if it is an imported radiator.

The most popular type of heating device is MC-140. This is a classic for most old-built apartments. The length of one section is 9.3 cm, the height is 58.8 cm. The area is 0.24 m². Based on this, you can find out the total area of the battery. The area of the section is multiplied by their number. As a result, a number is obtained equal to the area of the painted surface of the cast-iron radiator. It is better to always round off the result and take into account the paint consumption with a small margin for taps, couplings, adapters, etc.

A more modern or modified model of a heating device has a paint area for cast iron radiators of about 0.208 m 2. Accordingly, less dyeing material is needed.

Many internet sites now have dedicated online calculators. With their help, you can independently calculate the required indicator. To do this, you just need to enter the following parameters in the corresponding lines:

radiator marking according to technical documentation;
number of sections, their length and height.

After that, the program will make the necessary calculations of the area to be painted and give the desired result.

As you can see, it is not at all difficult to calculate the area of heating batteries for painting. After that, you can confidently proceed with the reconstruction of one of the main interior elements.

Calculation of the area of \ u200b \ u200bpainting a cast iron radiator

$Calculation of the area of \ u200b \ u200bpainting a cast iron radiator$

Heating systems are in every apartment. There are many types of radiators. They differ in weight, design, size, heat dissipation and other characteristics. Cast iron radiators are reliable and practical.Houses commissioned in the USSR were supplied with batteries that perfectly cope with their functions and heat the space of the apartment in the cold season. Modern heating systems differ from cast iron systems in that they are lighter and more attractive in appearance. But many people do not want to exchange their old cast-iron batteries for comfortable and beautiful modern radiators.

$Calculation of the area of \ u200b \ u200bpainting a cast iron radiator$

The advantages of cast iron radiators are high heat transfer, corrosion resistance, durability.

Once upon a time, batteries were painted with oil paints. Under the influence of constant high temperatures and significant changes, they fade, decay, crumble; batteries become unattractive, untidy. The question arises about their restoration.

So, you need to paint the old cast iron radiator battery. What is needed for this? 1. Preparatory work: removal of dust and old paint by chemical method First, dust is wiped with the help of improvised means, you can use a brush for cleaning dishes, damp gauze folded in a bundle. One end of it is threaded through the inner transverse plates of the radiators; 2 ends of the bundle are taken with the left and right hands, respectively; the device is cleaned of dust by alternately pulling the gauze from the left hand to the right. Then you can remove layers of peeling old paint, traces of corrosion. If the area of the old paintwork is small, the paint can be removed mechanically (by hand stripping).

For this you need:

sandpaper;
file;
brush with metal bristles.

You can also apply:

grinder;
special drill attachment.

$Calculation of the area of \ u200b \ u200bpainting a cast iron radiator$

Cleaning cast iron batteries before painting is a mandatory process, because the paint cannot hide the unevenness of the radiators.

The advantages of the mechanical method are versatility: it can be carried out on functioning warm, cold batteries connected and not connected to the heating system; it is applicable for any paint and varnish coatings (thermally sprayed enamels, oil paints, nitro paints, paints based on various resins, etc.)

If the surface area of the old paint is large, it is possible to remove the entire layer by chemical means. They are solvents, acids and alkalis. This method of removing old paint will require:

gloves;
respirator;
special curved brush;
loop;
brush with metal bristles;
putty knife.

The substance is applied with a brush to the paint to be removed. The application process is sometimes repeated several times at intervals of 5-30 minutes. After some time, the old coating dissolves or softens completely. It is removed with a spatula, brush, cycles. The cleaned surface of cast iron radiators is rinsed with water and dries up. It is best to perform these actions on a cold battery or on one that is not connected to the heating system. But for each individual case, the instructions for use of the selected chemical should be followed. Precautions include using chemicals away from open flames, in a well-ventilated area, using gloves and a respirator. 2. Thermal method for removing old paint, degreasing, calculating the area of the painted surface, primer

Diagram of a construction hair dryer.

When choosing a thermal method, the battery should not be connected to the heating system; it is dismantled. The method is suitable for removing strong layers that do not peel off. The surface of the radiator is heated. To do this, apply:

blowtorch;
construction hair dryer.

Heating is carried out until the paint begins to bubble. Then it is cleaned with a spatula.If not all of the old paint has been removed by this method, mechanical, chemical or combined methods are used. Precautions consist in observing safety measures when working with devices that create a jet of open fire, using:

gloves;
respirator;
protective glasses.

After work, you should leave the room for several hours and ventilate it thoroughly, because during the work, toxic substances are released that have a detrimental effect on the body.

The cleaned battery is washed with water and dried. Then degrease with a common solvent. She is now ready for painting.

First, it is primed. The primer is selected so that its characteristics are as close as possible to the requirements of the decorative paint used. To find out how much primer and paint is required, calculate the area of the surface to be painted. To do this, the area of one section is multiplied by the number of sections in the battery. To calculate the area of one section, multiply the height of the section by the length. It is best to use the reference literature or the technical data sheet of the device, where there are values for these quantities. A device of the MS-140M-500-0.9 brand with a section length of 93 mm and a height of 588 mm is considered quite common. The area of one section is 0.24 m². We multiply this number by the number of sections in the radiator and get the final number equal to the area of the painted surface of the cast-iron radiator. 3. The choice of decorative paint and painting of a cast iron radiator

$Calculation of the area of \ u200b \ u200bpainting a cast iron radiator$

Varieties of brushes for painting: a, b - flute brushes; c - round brush; g - radiator brush; d - maklovitsa.

After the primer has dried, paint the cast iron radiators. Today the industry offers a huge variety of decorative paints for painting metal surfaces. These are anticorrosive epoxy acrylic enamels, chemically resistant paints, resistant to high temperatures. If possible, the choice is stopped on paints that do not require special preparation of surfaces for painting. One of these paints is "Hammerayt", it can be used on warm, functioning batteries. Among its varieties there are those that create beautiful patterns on the painted surface, which forms an attractive radiator design that is in harmony with the interior design of the room.

To paint the radiator you will need:

gloves;
curved or regular hand;
improvised means (gauze, rags or foam rubber, fixed on a metal rod).

When working with brushes, the internal elements of the battery can be painted poorly, sometimes there are unpainted places. The disadvantage is eliminated by a simple action. As described at the beginning of the article, the gauze is folded into a bundle. It should be dipped in paint. Further, the same actions are performed as when removing dust. You can use foam rubber or rags attached to the rod. The principle of working with this tool is identical to working with a brush; its advantage is that when painting the inner surface of cast-iron radiators, it has more permeability than a brush. The metal bar can be bent if necessary, which provides more permeability in hard-to-reach areas.

The painted battery is left to dry.

Modern paints for metal surfaces are perfect for cast iron radiators, they form an attractive design of the heater.

Calculator for calculating paint for a cast iron heating radiator

Modern heating radiators - steel, aluminum, bimetallic and some others, go on sale with a high-quality, multi-layer protective and decorative coating.With careful handling, they can serve for many years without requiring additional painting - it is enough to regularly wet cleaning. The good old cast-iron "accordions" are a different matter: they must be painted both during the initial installation and at regular intervals during operation.

Calculator for calculating paint for a cast iron heating radiator

The painting process can be carried out by any owner of a house or apartment - the main thing is to choose for these purposes high-quality paint that is suitable for its operational parameters for heating devices. With paint consumption, at first glance, everything is also simple, since manufacturers indicate this parameter on the packaging labels of the factory packaging of the material. But here's the catch! - consumption is indicated per unit area, and looking at the complex configuration of a cast-iron radiator, it is problematic to estimate its area. Determine the amount of paint by eye? No, not worth it, it is better to use the calculator for calculating the paint for a cast iron heating radiator, posted in this publication.

Brief explanations of how to work with it will be given below the calculator.

What is the basis and how is the calculation carried out?

It will not be difficult to calculate the area of, for example, flat panel radiators, since the front panel to be periodically painted has a rectangular shape. With sectional cast iron - it is more difficult, due to their complex configuration, so the calculator was made specifically for them, as they remain one of the most common.

If you "rummage" in the technical characteristics of cast iron batteries, you can, if desired, find the value of their surface area. In order not to send the reader to independent searches, these parameters are collected in the calculator's database for the most commonly used cast iron radiators of the MC series, as well as for more modern ones - the FM series.

Please note that some radiators have modifications - internal fins, which increase the heat exchange area. Naturally, the paint consumption for such sections will be higher. Of course, the total painting area depends on the number of sections assembled into the battery. The calculator provides the ability to immediately calculate the paint for coating the supply and return pipes connected to the radiator

Factors affecting the consumption of materials for painting a radiator

The amount of material for painting heating radiators is calculated based on the area of the surface to be coated. To do this, you need to know the area of one sections of a cast-iron radiator and their total number. Often, the manufacturer prescribes these parameters in the instructions for the devices. In addition, it is necessary to take into account some of the nuances of the coloring agent itself. These include:

All this is taken into account when choosing a paint. In addition, they are guided by the type of battery and recommendations from the manufacturer.

Output

By choosing the right paint and following all the rules for surface preparation and painting, you can get a high-quality and beautiful radiator coating for a fairly long time. Just insert a small remark that acrylic paint for heating radiators, that water-dispersion paint is not as effective in production areas as powder formulations.

The procedure for calculating the area

A problem such as the poor look of old cast iron appliances is easy to solve, for which you need to paint their surface. First of all, you need to figure out how much primer and paint to purchase.

This can be found out by determining the area of \ u200b \ u200bpainting cast iron radiators. Then they study the recommendations that are available on the can with the coloring composition. They always contain information on the consumption of paint per square meter.

It is impossible to independently find out the area of a section of a cast-iron radiator for painting. This is not required, since the manufacturers of heating equipment provide this information in the instructions attached to the products. Rather, the documentation indicates the size of the heating area, and since every centimeter will warm up, this value is the size of its entire surface.

It is known that the rib area of the MS-140-500 product is 0.244 sq. m, and the modified section of this device, which has a center-to-center distance of 300 millimeters, has an area of 0.208 sq. m.

To calculate the entire surface of a cast iron radiator, you should:

find out the name of the model and, if possible, its manufacturer, since the same modifications of devices made at different enterprises have different parameters - width and depth;
determine the heating area of the rib;
multiply this value by the number of sections.

For example, in the MS-140-500 radiator there are 10 fins, then the surface area will be 2.44 square meters. m. After that, they determine how much and what building materials will be required. When calculating the consumption of paint for heating radiators, it is necessary to take into account that it must be purchased with a margin, since each layer of the coloring composition will have a different thickness.

Radiator area calculation

At the very beginning, you need to find out how much primer and paint you need to use to paint the battery. This can be found out by calculating the area of the heating radiator. Next, they look at the recommendations indicated on the paint can. They always indicate how much paint can go on 1 sq. m. Manufacturers indicate the heating surface area of the section.

One edge of the MS-140-500 battery has an area of 0.244 sq. m. A modification of this model with a center distance of 300 mm has sections with an area of 0.208 sq. m.

To determine the total surface area of a cast iron battery, you must:

Find out the model name of the installed battery and the manufacturer (because the sections produced by the manufacturers of the same models have different depths and widths).
Set the heating area for 1 rib.
Multiply the number of sections by the area. If the MS-140-500 radiator has 10 fins, then the surface area is 2.44 sq. m.

Having made the calculation, determine the amount of composition and primer. The paint should be taken with a margin.

Preparatory activities

They involve cleaning the surface of the battery from old paint and dirt:

Wipe the dust thoroughly with a damp cloth so that no dirt remains in the grooves. To clean hard-to-reach places, place a rag between the ribs and move it back and forth.

Remove the old paint layer. When the chemical method is used, Dufa, SP-6, B52, ACE funds are used, but they are not able to cope with the oil formulations that were produced in the middle of the 20th century. The physical method requires the use of a drill on which a metal brush is attached. You can also use a file and sandpaper.
A layer of primer is applied. It must not only withstand elevated temperatures, but also correspond to the type of paint, it is good if they are of the same brand.

How to independently calculate the coverage area and paint consumption

There are various ways to calculate the area of painting cast iron radiators, but it is useless to "reinvent the wheel".

Attention! Heating equipment manufacturers reflect this information in the technical description for the model.This value is usually indicated as "heating area", other options and translations are possible if these are imported models.

Calculating the area of color of a cast-iron radiator MC-140 as a classic sample, we take into account the area of one section or "accordion ribs". It is approximately equal to 0.244 m 2. A more modern or modified section with a slightly larger center distance (300 mm) has a painting area of the order of 0.208 m 2.

The radiator can be painted in any color that suits the overall interior

The models of cast-iron batteries can differ greatly, therefore, for calculations, we take the heating area of one section from the documentation (product passport). Next, we multiply by the total area of all ribs with a small margin (adapters, taps, couplings, legs). For example, in a standard MS-140-500 there are 10 ribs, we multiply by 10 the section area of 0.244 sq. M. We get 2.44 m 2. We round up to 3 m 2 - for all adjacent parts. Next, we decide how many layers the painting will be.

Innovative methods for determining the area of painting of cast iron radiators - special computer programs and calculators. They enter the following parameters:

radiator marking (according to technical documentation).
number of sections, their length and height.

Only with proper pre-cleaning of the battery will the paint lay perfectly evenly

On the issue, we have a real area of paint. After receiving the information, a "reset" is entered to clear the window and enter new data.

Calculation of the required amount of paint

Another important point before buying paint for a heating system is to correctly calculate the color of heating radiators.

Do not be alarmed, the procedure is not complicated, but you need to have some background information:

The area of the painted surface.
Consumption of a specific paint per square meter of battery.

For your information! The standard paint consumption for heating radiators of a certain brand will be prompted by the accompanying recommendations indicated directly on the product packaging.

Now let's learn how to calculate the total area of painting of cast-iron radiators and supply pipelines:

To calculate the area of circular pipes, you can use the well-known formula for the circumference L = 2¶D, where ¶-3.1415 ...; D is the diameter of the circle (pipe). Knowing the length of all pipes to be painted and their diameters, we calculate the area of pipe painting.
For such calculations with heating devices, you need to know the number of sections in each and the color area of one section. For us, the area of one section of a particular battery has already been calculated by their manufacturers. So, all that remains is to find this information in the documentation for the device and multiply this figure by the total number of sections.

For example, let's calculate the area of painting of radiators MC 140 M-500-0.9 consisting of 10 sections:

The section of such a radiator has the following geometrical parameters:

Height - 588 mm.
Length -93 mm.
Painting area - 0.24 m2.

Accordingly, a device of ten sections has a painting area of 10 * 0.24 = 2.4m2.
Further, the calculated area is multiplied by the standard consumption of the selected paint and the total amount for radiators is obtained.
We add to it the estimated amount of paintwork materials for pipes and find out the volume of the required purchase.

As you can see, such a calculation for a pipeline system is nothing complicated.

And, of course, do not forget that boring monotonous colors are no longer in vogue, today bright solutions for the interior are in trend.

Painting area of cast iron radiators: how to calculate paint consumption

Heating radiators that have served for a long period need revision. If repairs were made, then it is quite possible that the appearance of the structure needs to be slightly refreshed, that is, painted. To do this, you need to know the area of \ u200b \ u200bpainting cast iron radiators. High-quality heat-resistant paint is not cheap, therefore, having calculated its consumption, it is easier to save on repairs.
