How to remove paint from the window

For the removal of old paint from the window there are three ways. This is thermal (by heating), chemical (using different solvents) and mechanical (using grinding equipment). Each of them has its pros and cons, depending on a certain situation. Sometimes you need to use different cleaning methods combined. Let's look at each of them.

The first thing from the window to clean the cleaning was more comfortable, you need to remove the handles, locks, latches, gently remove the glass. The surface must be washed so that there are no dirt and dust.

We use the first method - thermal. His principle is as follows: It is necessary to heat the old paint so that it has become soft and it would be possible to remove the spatula. Heated with a soldering lamp, gas burner and construction hairdryer (temperature + 700-800 degrees). The hair dryer warms the hot air flow and does not give open fire, like a lamp or burner, so there is no danger of paint sunbathing. This method is simple, effective, but has its drawbacks. There will be a lot of smoke from him, which you can create inconvenience to you and your neighbors. Also can not be heated plastic, it is deformed by this. To remove the paint from the window with a construction dryer, heal the surface and immediately consider the composition with a spatula.

The chemical method is the least laborious. It is necessary to choose special solvents under a certain kind of paint, say, Washing SP-6, SMU-1/2, B-52. Also possible use of acids, alkalis, for example, casher, consisting of alkali eating, water and an inert filler. Use similar compositions in such a way: brush is applied to the old paint. It happens, it is necessary to apply the solvent several times after certain intervals, from five minutes before half an hour. After some time, the old paint dissolves or turns into a jelly-like mass. Now it is easy to consider it with a steel spatula. After removing the old paint, the window can be washed with water.

The mechanical method is the most time consuming. Paint is written with an electrical tool or manually. Bulgarian and drill are most suitable from the electrical tool. For them, there are special nozzles - wire brushes (crawling). Paint removal manually makes with a small amount of work volumes. To perform the procedure, scrapers, spatula, cycles, stops are used. After cleaner with sandpaper to remove scratches. The advantage of this method is that it is suitable for removing any kind of paint.

With all these types of work, it is necessary to comply with safety. A jet of flame or hot air is capable of burning. You also need to avoid touching hot burner parts. When using solvents can be poisoned by caustic agents. During the operation of the power tool, the particles of old paint are flying, which can damage the eyes. Therefore, use protective glasses, respirators and mittens.
