How to remove varnish from furniture?

Very often there is a need at home to remove its main coating from the furniture surface.

It should be noted right away that it is not easy to remove the varnish from the furniture and in some cases it is possible to completely get rid of the application only by cycling.


This fully applies both to the colored surface and to the furniture surface on which a black or matte shade of varnish is applied.

You can try to get rid of the coating in various ways, while you should consider not only the characteristics of the composition used, but also the material of the furniture.

For example, you can remove the coating from the oak surface using various methods, ranging from mechanical stress and ending with the use of various solvents.

This is due, first of all, to the fact that oak furniture has a fairly strong structure that is able to effectively counteract various chemical compounds.

In turn, removing the coating from a softer material will be much more difficult.

It should be noted that you should not even try to get rid of the coating that is applied to the furniture from chipboard.

If it is necessary to remove the coating as carefully as possible, then special chemicals should be used, which are called washes.

In this case, even ordinary acetone or methylated spirits can help get rid of furniture.

Quickly and effectively remove the old layer from furniture at home with special gels that should be applied to the surface with a brush.

To do this, thoroughly moisten the item with a chemical agent, and then cover it with a film for a while. After that, the coating is removed using a spatula.

Then the processed furniture should be washed well with water and dried. You can also remove the old coating from furniture using a special layer, which forms a layer of foam on the surface.

This tool, although it has good effectiveness, is used mainly when a thin coating is applied to the furniture.


The most time-consuming process of removing old coatings from furniture is cycling. In this case, the work will have to be done as carefully as possible so as not to damage the main surface of the furniture.

The varnish is able not only to give the furniture an aesthetic appearance, but also to protect it from moisture, mechanical damage, as well as dirt.

This coating should be selected based on its main characteristics, as well as the structure and operating conditions of the item itself.

If it is necessary to remove the coating from a wooden object, it is necessary, first of all, to choose a method that eliminates the possibility of damage to its base.
