Expert advice on paint removal

The most time-consuming renovation problem is cleaning old paint from the surface. It is no secret that the quality of the finishing depends on the preparatory work. If you don’t use tiles, PVC, or drywall, you need to become familiar with a number of technologies. The most affordable cleaning method is mechanical. It is noteworthy that thick layers are easier to remove than thin ones. To do this you will need a knife, chisel, and ax. This type of work does not generate a lot of dust, does not cost money, and can be done by anyone without specific experience.

Cleaning with power tools

If the surface area is large, it is advisable to seek help from specialized companies. As a rule, they have a fleet of construction equipment, materials, and protective equipment. Qualified specialists will complete the required amount of work in a short time and at reasonable prices. If you remove it yourself, you need to take care in advance of a drill with a metal brush or a paint remover attachment. You can also use an angle grinder, after putting on a protective suit and mask. Professional craftsmen use sandblasting. The essence of the treatment is as follows: streams of water or air (with abrasives) are applied to the base under powerful pressure. Hitting the surface, they simultaneously clean the walls.

Thermotechnology

Similar removal methods are used mainly for wooden structures. The process is carried out using a hair dryer. After directed supply of heated air, the staple easily removes paint. Hair dryers can be replaced with blowtorches or gas burners. But in some cases their use is prohibited. These are multi-apartment buildings, lack of individual protection devices, ventilation, proximity of plastic, metal structures or electrical wiring. Sometimes an iron can be used to remove paint. During the preparatory stage, foil is applied to the surface to be treated. After heating, the hot sole of the iron is passed over it. This method is more likely to be applied to small sections of walls and doors.

Chemical assistants

Treatment with chemicals does not create a lot of dust and effectively cleans surfaces of oil-based paint. You can use industrial solutions that are sold in retail chains. In this case, it is recommended to learn about all the disadvantages of this technique: reagents and their level of danger, cost, storage procedure. In addition, again, you need to protect yourself with goggles, respirators, and gloves. The processing sequence is not complicated. The composition is applied to the surface using a roller. Once softened, a spatula removes the original coating. At the end of the work, the area is washed with water. At home, you can prepare the wash yourself. To do this you need to have ammonia, chalk, quicklime, soda ash or liquid glass. For a high-quality result, the ingredients should be mixed in certain proportions.
