As soon as the repair is inappred, every time we wonder if you need to take paint from the walls and what a way to choose.
Content
A few more tens of years ago, there was an oil paint in each dwelling. The walls were fashionably paint, so in the bathroom, in the kitchen, in the corridor, and even on the ceiling, there was paint on the walls. Used in those times to dye the walls oil paint or enamel. Every year the paint was gradually eaten so much that it was now very problematic to remove it from the surface.
Wall cleaning methods
There are several, each - labor-intensive ways to clean the walls of the walls from paint. And the most difficult thing in repair is to remove the old paint from the wall.
Let's look at the methods of cleaning the surface from paint:
- mechanical;
- chemical;
- heat treatment.
The mechanical method is used often, although it is very laborious and not as effective as other ways to clean the surface from old paint. In short, the process looks like this: you need to take a spatula or any other tool with an acute end (you can scraper), also suitable emery coarse paper. Paint from the walls is moving, it is believed to be filmed with layers. Note, if only faster clean the surface from paint. The method, as already mentioned, is very laborious and does not always give a positive result. So you can prepare the room to finish.
A chemical method speaks for itself - special washes and other mixtures are used. Wall cleaning agents are different: liquid, semi-liquid and in the form of pasta. Sold ready or require breeding in water. Some are applied with a thin layer, some need to be applied with a thick layer. The main task of such a chemical substance is to soften the surface so that the paint can then be considered. Time exposure Tools Miscellaneous, usually a few hours are given to such a procedure. The abilities are also different for each material, some manufacturers ensure that the wash will cope with the 10th layers of old paint. Remains should be considered with the paint that remains on the surface.
Taster or roller are applied. Time is withstanding (indicated in the instructions), and then the softened paint should be removed by the spatula. This method, of course, is faster than removing the paint by hand, only the chemical agents are very toxic. Therefore, you need to work in a mask and gloves, as well as constantly ventilating the room.
And one more way to clean the surfaces and walls from paint is thermal processing. This method is effective if you need to quickly clean the wooden surface from paint. Used for these purposes a construction hairdryer or soldering lamp. It all depends on the area of \u200b\u200bthe processed area. More details we will return to this method to study the deeper the thermal process of cleaning the walls from the old paint, but for now let's prepare the necessary tools.
Thermal cleaning of walls from paint. What you need to prepare from tools
Repair - the work is responsible and you need to immediately prepare all the necessary tools and materials so that everything is at hand. If something is missing in the most responsible moment, then you have to stop, and then start all over again. Therefore, to immediately cope with the task, you need to prepare tools and materials.
What can come in handy in work:
- several spatulas;
- brush for cleaning walls with rigid bristles;
- emery coarse paper;
- knife;
- screwdriver;
- construction hairdryer or soldering lamp.
We also do not forget about safety measures: the hair needs to be covered with a hat or golk, put on a bathrobe, work better in gloves, and your eyes will help protect special glasses.
How to remove paint
It is known that if you heat the enamel or oil paint, then it first swept, then it foams and gradually peeling from the surface. This allows you to quickly get rid of the old coating. Therefore, if the plot is small, then you can use a soldering lamp to heat the paint if the site is large - then it is easier to work with a construction hairdryer.
The principle of operation is very simple: you need to warm up the paint, and then remove it with a spatula. Quickly and simply, if you need to handle a small area. This method works well if you need to get rid of the old paint on the wooden surface. Especially when the window frames and wooden doors are put in order. Remember that when heated, the paint sends toxic gases, so it is necessary to work in a well-ventilated room, and if it is possible, then make the door or window blocks into the street.
How to remove paint from the walls:
- the thermal method is good and it is good that you can quickly clean the surface from the layers of paint, only you have to warm up small areas, clean them, and then move on;
- in order to remove the old paint, you need to arm a construction hairdryer, turn it on and direct the stream of hot air to the surface being processed;
- cleaning the walls of hot air should be performed until the paint softens, and then remove it with a spatula;
- do not interrupt - if you leave your hand on your left hand and send a stream of hot air onto the wall, you can handle the softened paint, gradually moving and cleaning the entire surface;
- what did not succumb to the first time, you need to try to delete again. To do this, you can use the soldering lamp or turn on the construction hairdryer again. Paint residues believes with a spatula, sharp knife and treat the entire surface with sandpaper.
On advantages and disadvantages of the thermal method of cleaning walls from paint
The thermal paint removal method is very effective, because you can quickly handle a large area and clean the wall from the old paint. But there are some features that you need to know. So, paint is almost impossible to remove from plastic surfaces, because when heated plastic immediately melts and deformed. So if you need to remove the paint from such surfaces, then choose other methods.
And yet, the paint heats up and distinguishes toxic substances, and the use of rapidly heated devices (soldering lamp and hairdryer) is unsafe.
Method disadvantages:
- Paint allocates toxins when heated.
- Not all surfaces can be cleaned by this method. The plastic surfaces, metal and concrete surfaces are not subject to thermal processing. If you need to remove the paint from the plastered surface, then you also will not work.
- In places where there is electrical wiring and sockets, this method does not fit.
And it is also necessary to take into account that there are such types of paints that, when heated, is even better connected with a wall or another surface. Therefore, if you do not know which paint the walls and ceilings were painted, as well as doors or window frames, then you first need to try to warm up a small plot and see the result. If the paint melts, then you can proceed to work, and if it should be immediately baked, then you need to pick up other methods of cleaning the surface from old paint. And be the most careful as possible, because some types of paint are ignited with strong heating.
Pluses of thermal cleaning:
- With this method, there is no dust, hot paint is removed by formation.
- Fast cleaning of the surface from paint. The thermal method of getting rid of paint can be chosen if it is necessary to get rid of the old paint on wooden surfaces. For example, if houses from year to year wooden window frames or floors were painted with oil paint or enamel. Then you just need to warm up the paint with a construction hairdryer and consider the old layer. The surface is ready for new staining.
If you update old window frames, then naturally need to remove accessories (handles, locks, etc.), as well as remove the glass. Before starting work, you still need to wipe the surface to clean them from dust and dirt.
About safety technique
If there is no experience with heating devices, you need to try to abide care and work as little as possible. If you work for a soldering lamp and a jet of flames was directed to the skin, then with short-term exposure nothing will happen, but if you hold it for a long time, you can get burns. If you work with a construction hairdryer, then some details are very hot. In order not to get burns, you need to be as attentive and careful.
In any case, no matter what method is selected, you need to use the means of protection: put on gloves, glasses or keep a transparent shield, and hair remove under the cap.
