Cracks in the paintwork, faded shade and peeling paint on the doors can ruin the entire impression of the room.
There is a need to remove old paint. For this purpose, proven chemical, thermal and mechanical methods are used.

Should I delete it?
When choosing a method for removing old paint, The question may arise: should it be removed altogether? The answer to this question and the choice of coating removal method depend on the following factors:
- door surface type;
- condition of the coating;
- type of paint used;
- adhesion strength of the coating to wood;
- thickness and number of layers.
The most difficult thing will be to remove the layer of paint coating, which has good adhesion to the material, and the door itself has a complex surface topography and a lot of decorative elements.
If the door is designed for subsequent painting, then depending on the condition of the coating, you can get by with sanding. This is possible when the paint was applied carefully in one layer and does not contain peeling or chipping. The old coating is simply treated with sandpaper, and a new layer can be applied.
Old layers of paint that, due to atmospheric influences and time, have significant defects (chips, cracks, swelling) will have to be removed. It is also necessary to remove too thick a layer of paintwork that has hardened streaks and other results of careless handling of the door in the past.
Preparatory work
Preliminary preparation of the door requires cleaning it from dust and dirt. Also it is necessary to clean off the swollen layers, lagging behind the base. If one of the sides will be hidden in the future, for example, by leatherette upholstery, you don’t have to carefully remove the paint - just clean off the peeling.
Having decided on the nature and scope of work, you should select tools for removing paintwork.
You will definitely need:
- rags;
- putty knife;
- personal protective equipment (respirator, special glasses, gloves).
For the chemical method, you will need reagents, a bucket of water, and a brush for applying a special composition. The mechanical and thermal methods will require a special tool (grinding device, drill with attachments, industrial hair dryer).
How to clean at home?
To remove old paint from wooden doors one of three methods is used:
- Mechanical impact.
- Use of chemical reagents.
- Exposure to high temperatures.
Thermal methods
The thermal method of cleaning a wooden door from paint involves using an industrial hair dryer and a spatula.
Work order:
- Plug in the hair dryer.
- Direct a stream of hot air at the door area.
- When heated, the paint will begin to swell and come off, making it easier to scrape off with a spatula.
- The processing process is repeated in the next zone.
After the entire door has been processed, it is necessary to finalize the missing fragments. The surface is cleaned with sandpaper.
If you don’t have an industrial hair dryer, you can use an iron, first placing foil between the sole of the device and the door.
Advantages of the method:
- environmental friendliness;
- no extensive experience required.
Flaws:
- it is necessary to use a special tool;
- it is not always possible to use on difficult surfaces;
- there is a possibility of damage to the wood if the temperature setting is incorrect;
- may require modification.
How to clean a surface mechanically?
The mechanical method involves removing a layer of paint using tools: from a regular spatula to a drill with attachments and other special equipment. Using a power tool speeds up the process, but may not be able to handle difficult areas.
Disadvantages of the method:
- dust formation;
- high probability of physical damage to the surface;
- need a tool;
- the need to use protective equipment.
Advantages:
- environmental friendliness;
- Having a good tool speeds up the process.
Suitable paint stripping tools include:
Tool | Features of application |
Scrapers or cycles | For a flat surface |
Angle grinder | Gives a rough finish, provides access to corners |
Belt sander | Removing paint from hard-to-reach places |
Vibratory grinding machine | Delicate processing, removing a thin layer of coating |
Grinder with brushes | Universal processing |
Removing a multi-layer coating using only sandpaper or a spatula is labor-intensive and ineffective.
How to clean with chemicals?
Chemical washing is carried out using solvents. The technology is based on the destruction of the structure of the dye itself by chemicals:
- The solution is applied to the surface with a brush.
- Maintain the required time, which depends on the composition and type of paint.
- Using a spatula or scraper, remove the coating that has swollen under the influence of the reagents.
- Clean off any remaining paint.
If the instructions for the wash indicate that the surface needs additional wiping with white spirit or another solvent, this must be done.
Advantages of the method:
- speed of action of the chemical composition;
- ease of use;
- no excessive effort required;
- no special skills required.
Flaws:
- toxicity of chemicals;
- an allergic reaction is possible;
- mandatory availability of personal protective equipment;
- the need to organize good ventilation during the application of products;
- acrid odor;
- Solvents require special disposal.
Despite the fairly high efficiency, the use of chemicals often requires surface finishing mechanically.
The selection of the reagent should take into account the type of wood and the condition of the material. Rotten wood may not withstand intense chemical exposure.
How to avoid damaging the door leaf?
The wooden surface has a characteristic texture and is susceptible to harsh mechanical stress.
When working with natural materials, the following points should be taken into account:
- the spatula should be directed at an angle to the surface;
- movements should be in the direction of the fibers;
- to process difficult areas, it is necessary to use a special tool with a wedge-shaped nozzle;
- Particular care should be taken when working with soft wood, as well as with decorative elements that are milled.
In addition to updating the paint, you should pay attention to the condition of the fittings. If necessary, replace or restore metal elements.
9 important recommendations
Cleaning Tips:
- Work must be carried out using personal protective equipment.
- It is convenient to process removable parts of wooden fittings, such as door handles, separately.
- If the door is removable, then before cleaning it is advisable to remove it and lay it horizontally - this will make it more convenient to carry out work.
- For heat treatment, you cannot use open fire - only hot air.
- After washing, defects in the wooden surface must be eliminated by sanding or putty before covering with new paint.
- Before repainting, the wood should be primed.
- Using sandpaper to remove paint and sand can only be recommended if the wood door has a thin coating layer.
- It is recommended to carry out sanding work on wood with power tools outdoors.This will reduce the likelihood of the working part of the equipment touching a foreign object.
- When using chemicals to wash off, do not use plastic containers - the solvent can “corrode” them.
