How to remove paint from heating radiators

Than and how to remove the paint from the heating battery. means for removing the old paint before painting the radiator

Before proceeding to apply the paint to the heating radiator, its surface must be pre.prepared for painting. The preparation process can take more time than painting itself, but this will provide a better coloring.

The old, cracked paint and rust must be removed with a metal brush, sandpaper with large grain or special solutions that soften the paint and weaken its connection to the battery surface. Removing old paint and rust creates surface roughness, which provides a better connection of new paint to the surface of the radiator.

The use of manual mechanical cleaning tools (metal brush, sandpaper) is a long and laborious process that can be accelerated using a power tool. The most suitable tool in this case is an angular grinder with a special cleaning circle or brushing brush. However, using the corner grinder, you need to know the measure and not overdo it, t.to

Large revolutions of rotation allow you to quickly remove paint and rust, after which you can, by negligence, begin to wash the surface of the radiator itself (in the case of using a cleaning circle), which should not be done of course

The use of solvents to relieve paint (the so.called wash) is the fastest way to remove the old paint, but at the same time the most “harmful”.

Important! Special solvents for removing paint are a danger to human health. Therefore, when using them, good ventilation of the premises and the use of individual protective equipment (glasses, gloves, respirator or mask) is mandatory. Enamel acrylic “rainbow” for metal and heating radiators

There are 2 main varieties of washing:

Washing on a liquid basis is applied using a brush (this is their main drawback: the complexity of application to the internal parts of the radiator), after 10-15 minutes. The paint will soften and it can be removed with a spatula or metal brush. After that, with the help of a sponge, it is necessary to wash the processed surface with soap.

A solution with a liquid is in a high.strength container, so its transfusion is prohibited into another container. The 6-section cast-iron radiator requires about 0.5 liters. Washing.

Aerosol.based flushing is sprayed to the surface of the radiator from the spray can. The advantage of the aerosol is that it can be applied to the most inaccessible parts of the heating device. As a rule, aerosol washing are universal means and are suitable for removing any type of paints for the heating radiator, regardless of how much they are made.

Before spraying, it is necessary to carefully close all the nearby interior items, the floor and the wall behind the radiator. 15-40 minutes after applying aerosol, the paint is softened and it is easy to remove with any improvised means (spatula, metal brush, etc.D.).

Advice! As an anti.corrosion agent, corrosion inhibitors can be additionally used, which slows down or completely stop the corrosion of metal products. High.quality inhibitors are able to penetrate the radiator metal even through thick layers of corrosion. This allows you to get to the most distant sections of the heating device (clogs in the connections).

During thermal processing of the radiator, harmful substances are distinguished, so for work you will need personal protective equipment (respirator, rubber gloves, glasses), in addition to this work, it is better to carry out on the street, in extreme cases in a well.ventilated room.

For work you will need a construction hair dryer, a metal brush and a spatula. With the help of a construction hair dryer, the radiator surface is heated until the old paint begins to swell. At this moment, you can proceed to its removal. The disadvantages of the thermal method of removing the paint include that high temperatures can damage the inter.sequential gaskets of the radiator.

The mechanical method of cleaning

Brush for cleaning metal on an angular grinder

This is the most time.consuming method. To remove the colorful layer, tools with an abrasive surface are used: rashpili, files, sandpaper. But a durable layer is not easy to remove in the hollows of a granular and uneven surface of cast iron.

If the farm has a drill or angular grinder (angular grinding machine), then the use of technology can significantly facilitate the task. For these devices, there are special nozzles similar to round brass brushes or other metal. Before starting work, it is necessary to put on protective glasses and a respirator, since in the process many harmful dust (when using a corner grinder) and accidentally departed sharp fragments of hardened coating are formed in the process.

Fix a metal brush in a drill cartridge or on a corner grinder. Turn on the tool in the network and clean, slowly moving along each section by removing the old coating. If the bristles of the nozzle and a solid cast iron until the end of the work, then the brush should be replaced, and then continue the process.

The thermal method of cleaning the battery

Removing paint by an industrial hairdryer

If the radiator is not fixed on the wall, but is already purchased in the removed form, then it is easiest to clean it with fire. This will need:

It is better to work with an assistant, since you will have to almost simultaneously heat the paint and remove it. Protect the eyes and breathing organs with glasses and a respirator, put on gloves. Work is carried out only outdoors, in places safe from a fire point of view.

Put the radiator on the floor, light a lamp or burner. Direct the stream of flame to one of the sections and heat the paint until it starts to bubble. Remove the softened layer quickly remove. Continue to heat and scrape the coating until the radiator is completely cleaned.

When the battery has cooled, thoroughly remove the remaining paint with a metal brush. Apply a layer of solvent, wipe the radiator surface. After that, evaluate the quality of the work done. If necessary, the process can be repeated or improved by processing the surface with a grinding machine.

Batteries cleaned with fire or hard brush are covered with a layer of dust. This plaque must be thoroughly removed before painting using soap warm water. After removing dust, the radiator must be dried for 24 hours, and then decorate to your own taste.

Thermal method

This method is based on heating enamels with a stream of industrial hair dryer, as a result, the coating will begin to separate from the metal. You can then remove the softened paint with a brush or spatula. But the industrial hairdryer will not always help.

If there are a lot of paint layers, then it is best to use a soldering lamp. It will instantly warm the paint to a boil temperature, but be prepared for soot and highlighting harmful substances. It is best to take off the battery and engage in it in open air. Having decided to make in the house, do not forget about the respirator. Be especially careful, working with open fire in the room.

Methods of cleaning radiators

Before starting painting heating devices, it is necessary to remove the previous coating from them. There are several ways to remove the old paint from the batteries.

Option one. mechanical cleaning. You can use it for its implementation:

• special brushes for metal work;
• corner grinding machine;
• different nozzles for an electric drill;
• coarse.grained sandpaper.

This method is laborious, it will take a lot of time and patience for its implementation, especially the ribs of radiators.

Option two. cleaning using chemical reagents. Removing for paint from batteries is usually sold in glass containers. If construction washing is used, it is necessary to ensure the ventilation of the room and use the respirator.

There is a certain sequence of actions in how to remove the old paint from the heating battery:

• A little liquid is poured into the plastic cuvette;
• With the help of the brush, the composition is neatly applied to all surfaces of the device;
• withstand the period of time indicated in the instructions for the composition, most often it is 20 minutes;
• когда покрытие сморщится и начинает отслаиваться, его убирают со всех поверхностей радиатора, лучше всего для этого подойдет металлический шпатель средней ширины;
• The final cleaning is performed with a metal brush.

One liter of a chemical reagent will be enough to remove paint from a battery consisting of 10 sections. To facilitate the work before it is removed from the heating battery, its surface must be thoroughly washed with soap water and dried.

When the radiator is ribbed, the chemical composition is more convenient to apply with a sprayer. Before starting work, given the features of the mixture, it is necessary to remove objects made of plastic and rubber from the processing zone, and lay the oilcloth over the floor covering.

To remove paint and a primer from one battery, you need about one chemical reagent spray. After 30 minutes, the coating begins to swell. The paint becomes soft and it can easily be cleaned with a brush on metal or just a spatula.

Sometimes it is not enough once to remove the previous coating and then the procedure must be repeated. A way to remove old paint from the battery is selected individually.

The most common type includes washing in the form of a gel. They consist of components whose action is aimed at destroying the facing layer.

After the exposure of the gel, the process of peeling of an old layer of the paint surface occurs. As a result, the paint softens, becomes thin, exfoliates and is easily removed by a spatula. For work it is better to use the washing-gel that does not flow from the vertical surface.

When cleaning the old coating with a chemical composition in the form of a gel, it is difficult to process the inside of the heating battery. The washing procedure is carried out with caution. The composition should be in a special container made of material, characterized by increased strength.

Instructions for cleaning the heating radiator using a chemical substance in the form of a gel:

• The chemical is applied to the product with a brush from a factory capacity.
• The battery is processed using wide strokes.
• The composition is applied to the radiator for 5-15 minutes. Contact time depends on the state of the surface and aggressiveness of washing.
• The old coating layer is removed with a metal spatula or brush. It is important to make sure that the composition does not have time to dry.
• The heating battery is washed with soap solution, dried.

If everything is done in accordance with the instructions for use, there are no traces of old paint on the product.

The cleaning procedure should be carried out with caution. In order not to inflict harm to health with chemicals, you should use protective glasses, gloves, respirator.

Spray can

Aerosoli washes are suitable to eliminate any paintwork, do not harm the product. It is necessary to use this type of means taking into account the following security rules:

• cleaning is carried out in a well.ventilated room;
• flooring, furniture should be protected from aerosol;
• The work is carried out in rubber gloves, hermetic glasses, respirator.

Instructions for eliminating pipe paint from heating batteries using aerosol:

• Spray to the product aerosol. One spray is designed to process a cast.iron battery.
• After 15-30 minutes, the old paint is bloated.
• Further processing is carried out by a spatula.

Perhaps after the procedure it will not be possible to completely remove the old paint. In this case, after 2 hours, the processing should be repeated.

How to remove the old paint from the battery with the help of washing, will tell

Mechanical method

The mechanical method is the most difficult, but does not require cash costs.

The following set of tools will be required to work:

• To eliminate large bloating, it is better to use a drill with a metal brush;
• You can use a corner grinder with a kratsovka, a drill with a nozzle or a grinding machine with an abrasive circle.

After processing, a small amount of paintwork remains. It is not unlikely removed with coarse.grained sandpaper, a sharp spatula, a metal sponge, a file.

Removal of powder colors

If it is not so difficult to remove the old paint from the cast.iron battery, then it is much more difficult to remove the powder coating. The smooth polymer surface will clearly prevent good adhesion with new paint.

Only one way is suitable for solving the problem:

Preparation of the battery for painting. how to remove paint

Before starting painting a heating device, it is necessary to figure out the fact that it removes the old paint on the batteries and perform a number of preparatory measures. Otherwise, a new high.quality coating will not work out.

Before painting radiators, certain actions should be performed:

• Prepare tools and workplace.
• Remove the previous coating and the existing rust, having previously found out how to remove the old paint from the heating batteries.
• Clean the surfaces and degrease them.
• Apply a primer.

The most high.quality and beautiful coating is obtained if you apply it to the dismantled device. If it was connected to the heat supply system using an American or special sets, then you can remove the radiator without problems.

When it is rigidly fixed, then before removing the paint from the heating battery and applying a new composition, walls and flooring of the room must be protected from dirt, using polyethylene film or other materials. Also prepared in advance tools and everything else for repair.

Recommendations for removing paint in any way

We recommend: you are not in a hurry: there is a way not to pay for the removal of construction waste after repair

Surface processing with a special chemical system

Chemicals are applied only after disconnecting the heating system. Working with chemistry is not safe for health on a hot radiator.

The aggressive composition is dangerous for rubber gaskets that are at the junction of sections. Otherwise, the battery will flow in the future. These places are not processed by aggressive means.

Special chemistry tools are applied to the radiator with a brush. The main disadvantage of this method is the inability to qualitatively apply washing to the internal elements of the battery.

To work with chemistry, you need to observe security measures.

Important: you can not overflow a special chemical composition for removing the old km from the manufacturer’s container into your container. Tara for washing is created by manufacturers from particularly durable materials. Therefore, the composition is left in it.

The algorithm of exposure to the old KM chemical way:

• The brush is lowered into a capacity with a chemical product from the manufacturer. Impregnated to them.
• Smears are applied to the surface.
• Depending on the number of old layers and the deadline for their application, there is a time of washing. The layer bubbles in a maximum of 15 minutes. Standard consumption of universal washing. 1 liter per 12 sections of the battery.
• Until the swollen layer, it is removed by a spatula or metal brush.
• The last step will be wiping the battery with a solution with soap and its drying.

To correctly purchase a wash, you need to try to find out in advance the basis of the old km. If this cannot be done, then only universal compositions will help. Masters often use Paint Varnish Stripper. water.based composition. It does not flow from the vertical surface.

Both aerosol composition and liquid chemistry are used if you need to remove no more than 2 layers. Removing 10 layers will already be both expensive and dangerous for health. Since the product is applied to each layer separately.

Basic security measures

When cleaning the old layer of paint from the surface of the radiators, simple security measures must be observed. Despite the way to eliminate the obsolete enamel layer, all the work must be carried out, having previously put on protective clothes and securing the eyes and respiratory organs with glasses and respirator.

On a note! The most dangerous to human health is chemical cleaning. When using chemicals, you need to follow the safety rules for working with them. After all, such substances are caustic, toxic. Therefore, when working with them, it is necessary to carefully ventilate the room and prevent them from getting to the surface of the skin, use a respirator and put on gloves.
