Before painting a metal pipe, it is necessary to remove all layers of previous coatings so that the new one lays flat and does not subsequently peel off or crumble. How to clean a pipe from old paint? There are several options.

You can do this:

• using chemicals (special removers for metal work, such as Antikras-Universal, Antikras-Sprint, Body 700, PREMIA);
• mechanically - using special power tools.

What you need for work

Step-by-step instructions for using chemical cleaners

1. Clean the pipe from old paint using a special product. This method is suitable for those who have little time. The remover can be purchased at any hardware store. Before use, be sure to read the instructions.
2. Apply the product to the surface with a brush (or spray if it is an aerosol) and leave for 5-10 minutes, then scrape off the dissolved paint using a spatula or a sharp chisel. After this, wipe the metal with a cloth that has been previously moistened in the solvent.

You need to work in a well-ventilated area, since the chemical has unpleasant smell and toxic.

How to remove old paint from a pipe using power tools

1. To begin, put a special attachment with a medium coating on the sanding machine. With the power tool turned on, thoroughly treat the surface. After this, use a solvent to remove the remaining old coating. If necessary, repeat the procedure; if the nozzle is worn out, be sure to replace it.
2. The second option is to use a hair dryer. Turn it on and direct a stream of hot air onto the surface to be treated. After you finish blowing, remove the heated softened paint with a regular metal spatula.
3. You can also remove old paint from pipes using a grinder. Buy a special attachment for it in the form of a round metal brush, similar to the well-known metal sponge for washing dishes. Using a tool with this attachment, carefully treat the entire surface of the pipe, and then clean off any remaining paint with sandpaper or remove it with a remover.

Mechanical cleaning methods have one drawback - a huge amount of dust. Therefore, carry out all work in special clothing, safety glasses and a respirator or mask. Ventilate the room at the same time.

Now you know how to clean a pipe from old paint. Choose the option that suits you best and get started!

Again I hope for the all-knowing LW.:flower:
I searched in Yandex, searched here in the section - I did not find comprehensive information.
We changed the batteries in the summer, but we didn’t have enough money for pipes. I don’t want to look at this disgrace anymore. :)) Please tell the beginning “golden hands” how best to remove old paint from heating pipes? (and in general, is it possible to do this during the heating season - but I no longer have the strength to wait for summer with this monstrosity) And is it possible to do this in such a way as to minimize the pieces of old paint flying around the room.
Another question: what is the best way to paint (I have no idea at all:008:) so that it doesn’t smell terrible and looks good.
I'm also going to paint it at the same time. gas pipe.

In general, all advice is welcome and gratefully received.
P.S. Please don't hit me too hard, I've never done any repairs myself. Made through the efforts of other people.:flower:

Heat the old paint with a hairdryer and it will come off in rags from the pipe, you just need to help it a little with a spatula :))
Enamel for heating devices from Tikkurilla - the best choice.

Oh...wow. Can I ask a stupid question: if you heat a gas pipe, nothing will happen to it?:008:

13.11.2009, 11:50

Oh...wow. Can I ask a stupid question: if you heat a gas pipe, nothing will happen to it?:008:
I think we’ll find a construction hair dryer, because my husband works on a monolith.
uh-uh

uh-uh
It’s probably better not to heat a gas one with gas:005:

:)) Okay, I won't risk it. What would be better then - sandpaper?

13.11.2009, 12:09

Yes, there are all sorts of creepy chemicals:001: like removing old paint,
I was just scraping old paint off a gas pipe with a knife in the kitchen

Are there any paint solvents?
There is such a thing - a paint remover. applied to the old coating, after a while the paint is peeled off. There are different washes depending on the type of paint. effectiveness is individual in each case.

13.11.2009, 13:28

I'll tell you about my experience in order:

Using a hairdryer - you can get burned or damage what’s around, wallpaper and linoleum, the paint peels off to a C grade, then you still need to sand it, but this is probably individual, wooden surfaces climbed on Ur;

The remover has a terrible stench, and again you can damage the wallpaper and linoleum, the main thing is to take care of your hands, eyes and respiratory organs, washes off only 1 layer of paint at a time, if the vertical wash pipe flows down, and if it is also hot... this definitely not your option (((

Sandpaper is long, dusty and tedious, and ruins your manicure, but it seems to me the most effective. lay a damp cloth underneath and all the dust settles on it, I only made the gas pipe with sandpaper. :support:

Hm...
I got lost. The repairs have already been done. If I ruin the expensive AC-Creation wallpaper behind the chimney with a hairdryer, then they will send me to work))))
Apparently, you will have to use the old-fashioned method: a knife + sandpaper. I’ll put on three pairs of gloves))) Otherwise, I’m growing my nails for my birthday, it’s a pity, they’re already very long, like extensions :)
In general, it all comes down to the fact that you will have to persuade your husband to attend this event. I'll just paint it.

13.11.2009, 14:56

with a hairdryer - you can get burned or damage what’s around, wallpaper and linoleum, the paint peels off to a C grade, then you still need to sand it, but this is probably individual, the wooden surfaces are peeling off like crazy;
This is understandable. The thermal conductivity of wood is very low, but a metal pipe, and even filled with water, very effectively removes heat from the heating point and the paint does not overheat.
sandpaper is long, dusty and tedious, and it ruins your manicure, but it seems to me the most effective. lay a damp cloth underneath and all the dust settles on it, I only made the gas pipe with sandpaper. :support:
You can also try a manual cord brush or as an attachment to a drill.

Grinding with a machine is faster than just with your hands if you have one, of course, if not, ask your friends, but I wouldn’t buy it for one time.

13.11.2009, 20:15

try paint removers. I really don’t remember which company I used, but it looked gel-like, didn’t smear, didn’t smell, and removed the old paint well. in short I was happy

13.11.2009, 21:57

:)) Okay, I won't risk it. What would be better then - sandpaper?
Are there any paint solvents?

Wash or cord brush on a drill.

14.11.2009, 00:38

There are many paint removers (in the form of a gel and nothing pours. After 20 minutes the paint swells and is easily removed with a spatula). I would use them and then finish sanding (it's good if you have a power tool).
On the wall behind the pipe, so as not to damage the wallpaper, attach a film.
Good luck

Grinder (angle grinder - angle grinder) with a brush.
But there will be dirt

Is the old paint on the pipes in very bad condition? What I mean is that it can simply be degreased and simply painted without stripping it:005:

Tikkurila for batteries is the best choice, I agree with Pers. But I don’t know how it will fit on hot pipes..... I painted it on cold ones

I had the experience of painting while hot :), it was a long time ago, but I remember that I didn’t like the process: it hardens quickly, you apply a small layer - brush marks remain.....

By the way, if you really need to paint (i.e. over hot pipes) and the color scheme suits you, I would also consider Hameraite paint. I used it to paint a hot pipe in the summer.

Many owners of their own homes, when inspecting the condition of pipelines in the apartment, have to observe problems that have arisen with metal pipes(most often water pipes), in which traces of rust and dirt are visible through the damaged and swollen paint coating. Leaving them in this state is extremely undesirable, since further destruction of the metal can lead to a serious accident. It’s better to immediately figure out how to clean the paint from the pipe and paint it again.

When swelling is detected protective coating it is necessary to carefully examine the condition of the damaged area, after which it will be possible to decide on further actions. If, during the inspection, severe destruction of the metal is discovered under a layer of paint, you should think about completely replacing this part of the pipeline. But if it has only undergone corrosion upper layer metal - it is enough to carry out cosmetic repairs to the pipe, which consists of cleaning it of old paint and rust (followed by restoration of the protective coating).

Methods and nuances of cleaning

The choice of method for restoring the damaged section depends on the possibility of access to it, which, in turn, is determined by the location of this part of the pipeline. Thus, in areas where pipes are laid directly, getting to the damaged area is not difficult, which makes it possible to use conventional mechanical methods cleaning.

Note! There are always places on certain parts of any pipeline where access is limited. In this case, you will have to use the so-called chemical method involving the use of special cleaning agents.

Let's look at some of the features of each of these methods for cleaning damaged areas.

In order to remove paint from an area located on a straight run of the pipeline, you can use the following mechanical techniques:

• use construction hair dryer to heat the damaged area and then clean it of paint using a spatula or knife;
• in case of absence powerful hair dryer you can use a classic grinder or electric drill, equipped special nozzle in the form of a metal brush;
• if the layer of paint on the damaged area is thin, you can use a blowtorch to heat it up.

And finally, in the case where the paint easily comes off the metal, you can try to clean the surface with sandpaper of the required grit. Upon completion of such cleaning, you will definitely need to wipe the surface with a damp cloth, removing any remaining sanding dust from it.

Note! When access to the damaged area is limited (or if you do not want to waste time on long-term mechanical removal of old paint), you will have to use special chemicals. Note that their use is also possible in cases where you were unable to completely remove the old paint by mechanical means.

When considering the pipe cleaning process, we will proceed from the need to use these two methods together, which must be taken into account both when carrying out preparatory operations and when choosing the required tool.

In the case of chemical treatment (or when using one of the mechanical methods followed by additional chemical cleaning), you will definitely need the following tools and materials:

• medium size spatula;
• a set of brushes of various sizes;
• rags;
• special chemical solvent;
• scraper and knife;
• hand wire brush;
• a set of sandpaper of different grain sizes;
• drill with a special attachment;
• work clothes and safety glasses;
• respirator (mask).

Preparatory activities

Immediately before clearing the pipe of paint using any of the methods discussed, you should thoroughly prepare for carrying out repair work. This preparation consists of the following:

1. First of all, from the room in which toxic substances will be used chemicals, it is necessary to remove children, elderly people and animals, and then allow the influx fresh air to a given place (to ventilate the room, all windows and doors in the apartment are usually opened).
2. If there are carpets or rugs near the work site, they are removed and temporarily moved to another room. Such precaution will not allow the carpet fibers to become saturated with the pungent odors of chemicals, and will also eliminate the possibility of accidental damage during pipe processing.
3. In addition, all objects that interfere with it will need to be removed from the work area.
4. Before starting work with reagents, you must change into work clothes, as well as put on safety glasses and a respirator. If you do not have a respirator, you can use a gauze bandage (mask), which it is advisable to change every half hour.
5. After this, you should once again carefully examine the location of the damage and finally make sure that the metal base of the pipe is intact and does not need to be replaced.

Processing Features

Cleaning pipes mechanically is reduced, as already noted, to heating the surface with damaged protective layer and its subsequent cleaning using a spatula, a knife-cutter, a wire brush or regular sandpaper (the choice of a specific tool depends on the condition of the surface).

When chemical cleaning you can use the whole set special means(solvents and removers), widely represented on the domestic market these days. The following names deserve special attention:

1. Solvent B-52, which allows you to remove the most dyes various brands. Its use is reduced to soaking a rag with liquid, followed by wetting the damaged area with paint residues. For better decomposition of the dye, it is recommended to leave the rag with the reagent at the treatment site for 5–10 minutes.
2. Special washes used for both metal and cast iron pipes, most often having an unpleasant, pungent odor. It is in this case that the requirement for mandatory ventilation of the room, as well as the use of a respirator or protective mask, applies.

Note! The remover is applied to the surface to be treated using a brush soaked in the reagent for a period of 5 to 30 minutes (depending on the desired result). Before painting, pipes cleaned in this way must be given time to dry completely.
