This method has one significant advantage - the absence of any chemicals. But at the same time, be prepared for the fact that the process can be long, and it requires special care.

To mechanically remove the old coating, you will need tools . It is quite possible to take a metal plate as a tool, which should be sharpened first. This must be done in order for the tool to better cope with the task at hand.

Various types of sandpaper can also help in this matter. A metal bristle brush will come in handy at the very beginning of the preparatory work. You can also use a grinder or even a grinder, which will need to be equipped with a special attachment.

You can use a router if you have one in your home.

All of the above tools will help to cope with a small coat of varnish. When using tools such as a grinder or grinder, it is recommended to be extremely careful not to damage the structure of the product itself.

Work order

Before starting the process of removing old varnish, you need to prepare the furniture. An old table or sofa will need to be disassembled so that every detail can be carefully processed. It will be easier to remove the old covering from the door.

Prepare a special place at home, cover the floors with plastic, so as not to spoil the surface. It is advisable to carry out all procedures on the street, but if there is no yard, then you can do it at home.

The surface of each part must first be roughly processed ., be sure to use the special brush mentioned above. Next, it is the turn of using coarse-grained sandpaper, which also needs to be carefully processed the entire surface in order to remove the entire old layer.

After removing the old coating, the surface of the furniture should be treated with fine-grained paper in order to carry out the so-called sanding. After this procedure, you should get a smooth and clean surface, which must be sure to get rid of fine dust. This can be done very quickly, especially if you have a large, soft brush.

A sander can come in handy when it comes to a large surface.

For example, if it is a large wardrobe or table.

Chemical method

Many people are afraid of the mechanical cleaning method only because this way they can spoil the surface, damage the wood. In this case, it is recommended to pay attention to the chemical method, which is also effective, so that you can easily do everything yourself. This method is perfect if you need to remove an old finish from an uneven, grooved or carved surface.

Today there are many special products called washes . It can be liquid, powder, or gel. The liquid is perfect if the product has a maximum of three layers of varnish. For multi-layer coatings, gels are suitable. Powdered nail polish remover is ideal for large surfaces.

If you choose powder as a nail polish remover, it is recommended to slightly dilute it with water before use. It will be easier to apply a thick slurry evenly to the surface, and so the product will more effectively cope with its task.

The general algorithm for working with chemicals includes the following steps:

• Before starting work, put on gloves, a respirator, to reliably protect yourself. Remember that you are not dealing with harsh chemicals. Otherwise, the preparation process is similar to that recommended in the case of a mechanical method.
• Apply the flushing liquid evenly onto the prepared surface using a regular paint brush. It should be applied only in one layer, and then the product should be covered with a film. After a couple of hours it will be possible to open it. In the event that there are more than three or four layers of varnish, then the product must be left under the film for four hours or more.

• After the film is removed, you need to carefully remove the layers of varnish using a conventional spatula. Try not to work with pressure and do not pick up a trowel sharpened too sharply, otherwise the wooden surface will be seriously damaged.
• Then you can wash off the rest of the varnish with plain water. In order to clean the surface, you can add a little table vinegar to the water. Only one tablespoon of vinegar essence is used per liter of water. After that, the product will be ready for you to cover it with a new layer of special varnish.

In the event that the above method did not help to completely get rid of all layers of the old coating, it is worth repeating the procedure. If only small areas with old varnish remain on the surface of the furniture, then they can be easily removed with sandpaper

If powder or aerosol is used, the same instructions should be followed.

Other methods

In addition to the above methods, there are other cleaning methods, which in professional circles are usually called thermal or thermal. Using this method, the old furniture coating is removed by heating the surface. The varnish begins to melt a little from high temperatures and easily falls off the material.

Undoubtedly, this method requires more careful preparation, and laymen should approach the process competently.

It is recommended to remember some safety rules first:

Be sure to protect your hands with special gloves. If you use ordinary rubber, then during the strong heating of the surface of the furniture, you can get a serious burn

The room in which the whole process will take place must be well ventilated, otherwise you can get toxic poisoning

Do not forget about a respirator and goggles

In order to carry out thermal cleaning at home, you can use a gas or gasoline burner. You can work with this unit only if this is not the first time you are doing it. Inexperienced beginners can create hazardous conditions, fires, or serious burns. Therefore, it is recommended to strictly adhere to the safety rules.

Also, a building hair dryer can act as a heater. But, unfortunately, not every home has such a device, and its price is not as affordable as that of a burner.

The thermal method is a very fast process . Heat the surface to such an extent that bubbles form. Then the old varnish must be carefully cleaned with a spatula. Heat a small area, clean it off and move on. So it will be possible to more thoroughly and accurately carry out all the work. After all the old varnish has been cleaned off, sand the surface with sandpaper.

Each method has its own advantages. If you approach the process, taking into account all the recommendations and advice, then everything will definitely work out.
