How to remove old paint from a heating pipe - chemical and mechanical methods

click fraud protection

Painting heating pipes over the previously applied layer of paint is undesirable, even if it seems that the old one has no damage, and the only task of such minor repairs is just to update it. The reason is the specifics of the operation of the system. The temperature drops lead to a gradual deformation of the paint and varnish coating. Even if its defects are not visually visible, the risk of detachment is even large enough for some sections.

The application of a new paint will only give novelty to the whole contour, but it is not known how long it will last. In order not to engage in the same work after a short period of time, the pipes must be carefully cleaned to the base( metal).How to remove the old paint from the metal, which exist for this technique - all these questions will be discussed in this article.

Methods and means of removing paint from metal

Chemical

to-1 Aerosols

Commercially available products are universal, as they are intended for softening practically any soil, paint and varnish, and some for rust removal. Approximately half an hour( ± 10 min, depending on the manufacturer), the expanded paint mass is easy to remove mechanically. For example, a spatula, a knife, a chisel.





The price - from 188 rubles / point.(0.5 ml).

Flushing

Such a tool is called. Unlike aerosols, they are not sprayed, but applied with a brush. The processing process is longer, but as practice shows, their consumption is much lower.

The price - from 258 rub / liter.

Solvents

The specific agent is selected depending on the type of paint. This technique is applicable to the removal of the old layer only in certain areas, and then, if its thickness is insignificant. It is not very efficient and is used less often.

 Features - any "chemistry" contains toxic components. Before use, care should be taken to protect the equipment and ensure good ventilation in the room.

Mechanical

The choice of tools and devices is limited only by the presence of what is in the house.

  • Al / drill( perforator, "bulgarian") with a nozzle( such nozzles are described here).It is advisable to use if it is necessary to remove the paint from the pipe on a fairly large( length) section.
  • Brush with metal "villi".
  • File with large teeth( eg rasp).
  • Abrasive paper with large fractions of abrasive.

Thermal

The meaning of this technological operation is in the heating of the metal, after which the softened paint layer is removed mechanically. Basically, a hair dryer( construction) is used for this, and a soldering lamp is used less often( with some precautions).

Practical recommendations for the removal of

to-3 paint Using mechanical methods for cleaning pipes from paint, rust, do not exert significant effort. The "mode" of surface treatment should be gentle. Why? It is visually difficult, especially under a layer of paint and varnish, to determine the degree of deterioration of the metal. Consequently, excessive zeal can lead to the appearance of cracks, depressurization of joints. The result is the emergence( perhaps, after some time) of leaks and a new, but more extensive and complex repair.

 Before processing the pipe with any preparation, it is necessary to securely cover all adjacent surfaces. And not a newspaper that is done quite often before painting, and waterproof material( better - a rubberized cloth).

Such a safety net will not be superfluous, as it is not known how the "chemistry" behaves when it comes to contact with the floor covering, the finishing of walls, skirting( especially if they are made of new-fashioned plastic).
