How to clean varnish from a wooden surface. How to remove varnish from a wooden surface: the main options

Not every professional will cope with the task of restoring furniture. Several methods can be used to address this issue. It is important to completely remove the old coating. But, before embarking on such a procedure, it is necessary to figure out how to properly remove varnish from furniture and what methods exist for this.

The following tools are needed to remove varnish:

• polyethylene film;
• hair dryer, which is used specifically in the construction industry;
• blowtorch;
• hard metal brush;
• soft sponge;
• tassel;
• respirator along with a mask for protection;
• a special chemical composition that washes everything;
• glasses;
• rubber gloves;
• sandpaper;
• sanding skin.

Existing withdrawal methods

Regardless of the method chosen, it is important that the work is done quickly but accurately.

Here are some of the most common options for those who want to understand how to remove varnish from furniture:

• chemical;
• mechanical;
• thermal;
• water.

Chemical

This is an effective solution for the procedure at home.

It is important not to forget about a cotton suit that will protect the outer layers of the skin from active substances. A mask and goggles, rubber gloves are also mandatory requirements for those who decide to remove old material.

The furniture complex itself for chemical cleaning of varnish is called a wash. It is usually produced in the form of a special powder or mixture that corrodes paintwork in ten or more layers. Lacquer remover is easily purchased in specialized stores.

The stages of removing varnish from furniture can be described as follows.

1. The first is preparation. He assumes that, according to the instructions, the powders are diluted with a certain amount of water. To obtain a thick and homogeneous consistency, all the components that make up the composition are diluted with each other. Gel formulations adhere to surfaces easily, even on vertical ones. Taking it off, you also don't have to worry about the result.
2. Wash. A paste-like substance is applied to the furniture. A key step in the process. For application, it is recommended to use a regular brush. The surface is processed in thick layers. The movements are carried out in one direction, then you do not have to process the surface again.
3. Next comes the application of special films. This step is necessary to enhance the effect of the wash. To do this, take a film of polyethylene, and cover the treated surface with it. The film must be left in this place, no more than 1 hour. But it is better to leave the whole structure for 3-4 hours. The quality of the varnish itself and the thickness of the coating from it determine exactly how much time must be spent in this or that case. The film is removed when the stage is completed. We get a perfect polished surface. You need to remove the film after the appearance of a dark brown tint. The paintwork itself swells at this moment.
4. Next, proceed to the removal of varnish. If the previous steps are done correctly, then this moment will not cause any trouble. Just take a spatula and get rid of the remaining particles of material. Next, they take paper from sandpaper, it is passed several times over the base of wood. This allows you to remove parts of the material that remained after the previous processing. Removing polish from furniture is not so difficult.

It is advisable to use a spatula that does not have sharp edges. If the tool is new, it is recommended to hone it. Otherwise, the furniture itself will be damaged, requiring cleaning. Plastic tools are most suitable for this work.

Finally, it remains only to eliminate the wash. In this case, we need at least 0.5 liters of ordinary water. We dissolve vinegar in it, in an amount of 100-150 milliliters. We lower the sponge into the resulting solution, and then wash the entire surface. Wipe dry with a flannel cloth. When the furniture is thoroughly cleaned, it is exposed to fresh air. How to remove leftovers, we have already figured out.

Mechanical

There are several options for the so-called mechanical processing. The buyer decides what is suitable.

Option number 1

It is suitable if delamination occurs in fragments. The main tools are fine sandpaper or a steel brush. They perform circular movements: this is how the old varnish comes off the furniture without any problems at all.

Screwdrivers or spatulas help to get to hard-to-reach places.

Option number 2

How to remove the polish if the previous methods did not help? In this case, you can not do without an eccentric type grinding tool and hard sandpaper.

It is important to wear gloves and goggles for added protection before you get started. The following diagram will help you understand how to remove unnecessary parts.

1. We fill a special machine with sandpaper with a grain size of 80 to 120.
2. The surface is carefully processed as a whole.
3. Sandpaper is replaced with grit up to 180 points.

The wooden lacquered surface is processed using the same tool. The main thing is to make sure at the end that there are no particles of varnish left, and that the removal is complete.

Thermal

A building hair dryer or blowtorch is required when implementing this method.

The solution has two important advantages:

1. High quality cleaning.
2. Fast execution of all stages.

It is enough just to follow the rules so that the varnish from the wooden surface comes off easily.

During the first stage, one of the fragments of the wooden base is subjected to heating. For this, a blowtorch or a hair dryer is used. With a construction knife or a spatula, you need to clean the base from the paintwork that has been melted.

If you don't work fast enough, the varnish will have time to dry again. After one piece, move on to the next. Gradually, the varnish is removed from the entire surface.

When using the thermal technique, one must be especially careful. When firing, be sure to maintain a certain distance. Violations in the temperature regime are also unacceptable. Otherwise, the color of the wood will not change as it should, the removal will not be successful.

Water

Refers to the simple and safe options that are assumed in this case. The main tool is a sponge, which is properly saturated with water. Then the surface to be cleaned is thoroughly wiped. Gradually, under the influence of moisture, the coating is cleaned.

Purchased processing aids

It is necessary to understand how strong the initial destruction of the material is, what tools will make it easier to do the job.

Powder materials in this regard are considered the most professional solution, although the paste also pleases with the result. They remove up to ten layers of varnish without any problems. It will be enough to dilute the composition with water until a pasty substance is formed. With a brush, it is simply applied to the surface where the old varnish was. The work of removing old varnish from old furniture should be carried out evenly, without repetition.

Ready-made liquids or gels do not require dilution with water. Such compositions are immediately ready for application using a brush. But these tools remove only up to three layers.

The most convenient remedy for old varnish is spray, but in terms of efficiency it will lose to analogues.

After applying any of the means, the surface is closed with a film. Then it is left like that for a while. The coating material is removed when the color becomes dark and the varnish itself becomes viscous. The old coating is simply removed with a spatula from the tree. The main thing is to remember that in the future varnished surfaces require special care.

How best to remove old varnish (2 videos)

Nail polish removal methods (22 photos)

In this master class I want to talk about how to make a new one out of an old beech bureau, give special attention to the process of removing varnish and how to do it in hard-to-reach places.

To begin with, we will disassemble the bureau to the last screw. If you are afraid not to remember which part was attached where
- mark with a pencil the attachment points in Latin letters or numbers.

After parsing, you can remove the varnish from each part separately. Which in the future will improve the quality of painting.

I use BOSNY remover for paint stripping. It penetrates the composition of the varnish faster, and it has less consumption per m2.

We apply the composition of the wash with a brush, with a layer of up to 5-7 mm. After application, wait 15-20 minutes (depending on the thickness of the varnish layer). During this time, the wash penetrates into the composition of the varnish, as if "thinning" it. It is convenient to remove with a spatula. As you can see in the photo, the old varnish easily leaves, evenly peeling off the wood with a homogeneous film.

If the varnish has not come down to the end, the procedure can be repeated.

This is what the surface looks like after washing. When slight stains of the remains of the wash and varnish remain on the surface of the wood, acetone comes into play.

We apply acetone to a rag (I use pieces of a terry towel) and remove unnecessary residue from the tree, wiping the surface up and down.

Clean and smooth surface ready for painting.

And how to clean the varnish from a carved baluster if you do not have a lathe?

We put the baluster on a cotton cloth (I have an old sheet), pour it abundantly with acetone, wrap it in this cloth. Wet again with acetone so that the entire fabric is wet. Then wrap in cellophane and leave for 20 minutes.

Next, you need a bolt with a diameter the same as fastening the baluster to the table base. A nut is screwed into the bolt so that it does not go deeper than necessary into the base of the baluster. The head of the bolt is cut in advance for attaching the bolt to the drill chuck.

We also need a metal sponge for washing dishes.

We screw the nut into the baluster. In this case, a low-power cordless drill will not work, there is a chance that it will burn out. Take a regular corded drill more powerful. Scrolling the baluster, grab the baluster with a metal sponge with your other hand and remove the varnish soaked in acetone. After, remove the baluster from the drill and manually go over with 320 sandpaper.

This is how the impure differs from the purified. The balusters are ready for painting, without streaks and scratches from sandpaper.

After such a procedure, the balusters will smile at you.

Bureau cleaned and ready to paint. We start to paint. Places where you want to make scuffs, smear with candle wax. After staining, the paint can be easily removed from these places.
We paint with acrylic paint in several stages. The paint is diluted with water and applied in 3 layers. Each layer dries 1 - 1.5 hours. After drying, each layer is rubbed with sandpaper 320.

Parts are ready for assembly. Everything is simple here, we insert the dowels into the grooves, having previously smeared them with glue. Fasten with clamps.

We wait.

While the glue dries, we can decorate the handles for the drawers. You will need glue for the potali, potal and a little patience. Apply glue to the handle and wait 20 minutes. Gently apply the potal and smooth with a dry brush. Remove the rest of the sweat and the handle is ready.

Creative success!

The process of restoring furniture is a rather difficult task, for which you can use several methods. The restoration procedure consists of several stages. One of the most important steps is to remove the old varnish coating. Therefore, you need to figure out how to properly remove varnish from furniture, and at the same time not damage the wooden surface.

Choosing a paint stripper

Before you start removing the paint and varnish material from the wooden surface of the furniture, you should stock up on the necessary tools, which will vary depending on the method you choose.

The entire list of tools required for the procedure:

• sanding paper;
• sandpaper;
• rubber gloves;
• glasses;
• special chemical composition for washing;
• respirator and mask for protection;
• tassel;
• soft sponge;
• hard brush made of metal;
• blowtorch;
• hair dryer used in construction;
• polyethylene film.

Choice of removal technique

Whatever method you choose to remove the paintwork, you need to remove it carefully and carefully.

The main thing is not to damage the wood coating itself, otherwise you will ruin the entire restoration process. After that, you should decide by what method you will remove the varnish from the wooden coating.

The main methods used today are:

• chemical;
• mechanical;
• thermal;
• water.

Chemical method

The chemical method will effectively remove varnish from old furniture at home. To carry it out, you must wear a cotton suit, protective rubber gloves, a mask and goggles. This is necessary to protect against chemicals that contain acid. Therefore, if it comes into contact with the skin, these chemicals can cause burns.

A complex of chemicals for removing varnish from old furniture is called a wash. It is a special powder or mixture that, due to its chemical properties, can freely corrode up to ten layers of paintwork. This tool can be purchased in specialized stores.

Stages of chemical nail polish removal

1. Preparatory stage. At the preparatory stage, it is necessary to dilute the dry powder with the amount of water indicated in the instructions. All components of the solution should be stirred in order to obtain a paste of a homogeneous thick consistency. It is important to remember that such a paste in the form of a gel can even stick to a vertical surface.
2. Wash. This stage, which consists in applying a pasty wash to the furniture, is one of the key ones. The mixture is best applied with a regular brush, treating the surface with a thick layer. Brush movements must be carried out in one direction so as not to apply the mixture repeatedly on the same area.
3. Application of a special film. This stage is necessary in order to enhance the effect of washing. To carry it out, you should take a film of polyethylene and cover it with the surface with the applied wash. This film should remain on the surface for at least an hour. It is best to leave it for 3 or 4 hours. The time for which the film is applied depends on the thickness of the paintwork and the quality of the varnish itself. At the end of this stage, the film is removed. It must be remembered that the removal of the film is possible only when the color of the wash darkens and becomes dark brown. In this case, the paintwork should swell.
4. Lacquer removal step. If you did everything right in the previous steps, then you can easily remove varnish from old furniture even at home. To do this, you need to take a spatula and use it to carefully remove the peeled particles of the paintwork. Next, you need to take sandpaper and walk it several times on a wooden varnished surface. So you can remove all the remnants of varnish that have not been removed with a spatula. In this case, it is desirable to use a spatula that has non-sharp edges. Therefore, if you are dealing with a new tool, then you need to sharpen it a little with a grindstone. Otherwise, a spatula that is too sharp can damage the wood furniture you are cleaning. Therefore, a plastic tool, which is considered less rigid, can be an excellent option.
5. Wash elimination stage. To remove the remains of the wash from the varnished coating, take at least 0.5 liters of plain water and dissolve 100-150 ml of vinegar in it. Dip a sponge into the resulting solution and thoroughly rinse the surface with it. Then wipe the surface with a flannel cloth. Thoroughly cleaned furniture should be left to air dry out of direct sunlight. This step must be carried out quickly so that the wooden surface is not exposed to excessive moisture.

Mechanical Methods

There are several options for removing varnish from old furniture mechanically. Therefore, it is better to study each of these options and choose the one that suits you best.

First option

This method is better to choose if the paint material peels off in fragments. To perform this technique, you should take coarse sandpaper or a steel brush. With these tools, it is necessary to clean the surface using circular motions. Next, you need to take a screwdriver or a spatula, with which you can remove the varnish even in hard-to-reach areas.

Second option

This technique is more effective and is used if the varnish coating has not yet begun to peel off. Here you will need an eccentric type sander and hard sandpaper.

Before carrying out work, wear protective goggles and a mask. Further, using a machine filled with sandpaper with a grit of 80 to 120, the surface as a whole should be carefully treated. After that, in the machine, the previous version of the sandpaper is changed to a material with a grain size of 180.

This tool should also be walked on a wooden lacquer finish. At the final stage, you should make sure that no fragments of varnish remain on the furniture.

In general, mechanical methods are recommended if, after removing the varnish, you plan to apply enamel or other paintwork to wooden furniture. This is due to the fact that mechanical processing can lead to damage to wood.

Thermal way

If you plan to remove the varnish coating using the thermal method, then for this you will need a building hair dryer or a blowtorch. The main advantages of the thermal method of removing varnish are the speed of work and the high quality of cleaning. However, to get good results, you will need to follow all the rules for implementing this technique.

At the first stage, it is necessary to heat a certain fragment of the wooden surface from which the varnish is to be removed. This should be done with a hair dryer or a blowtorch. After that, using a spatula or a sharp knife, carefully remove the melted layer of the paintwork.

It is desirable to work as quickly as possible so that the varnish does not have time to harden again. After removing the coating from one area, they proceed to remove the varnish from the next fragment. In this way, the varnish coating is gradually removed from the entire surface of the furniture.

The thermal technique requires special care. To do this, strictly observe a certain firing distance and not violate the temperature regime. This will prevent the blackening of the wood.

If you do not follow all the rules, then the wooden coating may become unusable. Therefore, when smoke or bubbles appear, you should immediately stop and remove the tool from the wooden surface.

water method

Water nail polish removal is the safest and easiest way. The main tool here is a sponge, which must be well moistened with water. Next, use a sponge to wipe the surface that is planned to be cleaned of varnish. Liquid that gets on the paintwork will gradually dissolve it.

On a richly wetted surface, it is necessary to walk many times with sandpaper with large grains. These steps must be repeated until the paintwork material becomes gruel. After the complete removal of the varnish, the wooden furniture is thoroughly washed and dried. At the final stage, the surface is processed with fine-grained sanding paper.

Thus, the removal of paintwork material from old wooden furniture can be carried out in several ways. In this case, in each specific situation, you need to choose the most optimal way to remove varnish.

Wooden floors are often coated with special protective agents (most often polyurethane or acrylic varnishes), which form a beautiful matte or glossy film. The surface of such a floor becomes elastic, durable, resistant to abrasion and scratching. However, sometimes it is worth updating the coating so that it enhances the performance of the tree. Moreover, the varnish dries, no matter how many layers you apply, quickly enough (1-2 hours). And for this you have to remove (wash off) the protective layer of varnish from the floor.

We will understand below how the acrylic agent is applied and what the technology for removing it before the next coating consists of.

Important: it is imperative to wash off the acrylic varnish from the wooden surface before applying a new layer of coating. Otherwise, too many layers of protective material that dries quickly will simply swell over time and peel off in ugly pieces.

Nail polish removal: ways

The newest and easiest way to remove varnish is to wash it off. Moreover, the price of the product starts from $ 3 per 1 kg. The technology for removing acrylic coating consists in applying a special chemical agent to the wooden surface, which corrodes the varnish and lifts it from the tree.

In modern stores, you can buy chemical washes in the form of a powder, creamy paste or ready-made liquid, the use of which is quite common today. In the first case (wash-powder), it is necessary to mix the components of the product in accordance with the instructions indicated on the package. In other options (cream or liquid composition), the washes are already ready for use.

Varnish removal technology, or how to wash off the old coating:

• We prepare a chemical wash by thorough mixing;
• We remove all pieces of furniture from the room;
• We apply the chemical composition with a convenient brush or roller for the floor;
• Cover the treated coating with a film and wait 1-2 hours;
• Now you can carefully, without touching the wood, remove the old acrylic lacquer with a spatula. If unpeeled areas of varnish remain on the floor, you can once again treat the floor with a remover.
• When working with a brush or roller, it is important that the tools move in the same direction and do not work twice on the same area of ​​the floor.

Important: one application of a chemical nail polish remover can cope with 2-3 layers of coating. At the same time, powder preparations immediately overcome up to 10 layers of acrylic varnish. The consumption of a powder chemical wash is 1 to 10 when mixed, which is very beneficial.

• When the old coating layer is removed, the floor must be washed with water and detergent and the wood must be dried thoroughly.
• Before applying a new varnish, the floor should be covered with a layer of antiseptic primer. How many layers of antiseptic to apply is up to you. But at least 2 times is better. Applied with a brush or roller, the primer will subsequently protect the wood from decay, mold and bugs.

A few tips:

• When working with the use and application of a chemical remover to remove paintwork materials, use spatula with rounded edges. So you reduce the risk of damage to the parquet boards. You can purchase such a tool in a specialized store (its price is $ 0.3 each).
• Don't Forget Protective Equipment- mask and gloves. Their price is also available in specialized stores. Therefore, it is not worth saving on health.
• Ventilate the room more often so as not to be poisoned by volatile vapors of chemistry.

Mechanical polish removal

• You can also remove acrylic lacquer from the floor with primitive sanding. To do this, you can use either a grinder or a professional unit. In the first case, you can do the work yourself, but be sure to use goggles, a respirator and headphones. The grinder should be moved along the floor from the walls to the center of the room and closer to the exit. All wood-lacquer dust is subsequently removed with a vacuum cleaner.
• In the second case, it is better to invite specialists. Because handling a heavy scraper requires skill. The price of floor processing will depend on the square, but on average it starts from $ 5 / m2.

If you decide to cope with the cycle apparatus yourself, then consider some features:

• When turning on the unit, it is better to raise it, since the grinding elements can go deep into the floor boards and deform it ugly;
• When turning the machine indoors, it is also recommended to slightly lift the unit towards you;
• It is better to move along the perimeter first diagonally and only so that the grinding unit overlaps a little along the already processed strip. After that, it is worth changing the direction of the unit in the opposite direction diagonally.
• Lacquer removal in this way can be carried out both in large rooms and in small ones.

Important: after processing the floor with a scraper, it is necessary to remove the remaining dust (however much) and, if necessary, repair the damaged floor elements. It is necessary to cover the tree with new layers of paintwork materials with a brush or roller, moving along the fiber of the tree.

thermal method

Here, the technology for removing acrylic lacquer is to strongly heat the floor. Under the local influence of high temperatures, the paintwork material will begin to swell and move away from the tree.

You can use either a blowtorch or a building hair dryer for work. In the first case, the work will move a little slower.

Important: to perform this technology, you need to stock up on goggles, gloves, a respirator and a rounded spatula. Remember to ventilate the room well.

Work performance technology:

• The floor, varnished, is completely free from all pieces of furniture;
• Using a heating device, we locally increase the temperature of the floor;
• We immediately remove the lagging varnish with a spatula, moving further across the room.

Important: if the varnish is charred during heating, this indicates that its composition requires the intervention of a chemical remover to remove it. Therefore, heat treatment is not your case here.

Refinishing the floor

• Applying new layers of varnish must be carried out only on the prepared floor. Therefore, you first have to dry the boards well and clean them of dust.
• Before applying varnish with a brush or roller, the wood should be treated with an antiseptic. In this case, you need to make sure that the wood is well saturated.
• After the antiseptic is completely dry, you can start varnishing the floor. How many layers of coating to apply, decide for yourself, but always at least 2.
• Since the acrylic product dries from 2 to 4 hours, it is worth pausing between the stages of applying varnish. As soon as the previous layer dries, you can apply a new one.

Consumption of acrylic varnish for wooden floor is mainly 100-120 ml/m2. Therefore, it is important to carefully calculate the amount of funds needed and buy it at a bargain price. At the same time, we note that the price of acrylic varnish at points of sale is from $ 50 for a 5-liter canister.

It is worth remembering that the average consumption of varnish during the first application is about 1 liter per 8-10 m2. When the agent is reapplied, its consumption is significantly reduced and already amounts to about 1 liter per 12-15 m2.

Important: Reviews of the work on removing varnish from many users still indicate in the direction of chemical washes.

Old woodwork or lacquered furniture can be brought back to life and made to look just as attractive as it was originally.

Sometimes, in order to paint a wooden surface with a covering paint or cover with a glazing composition, the old varnish must be completely removed. Otherwise, all the work will be in vain, money and time will be wasted.

This occurs if, for example, very large areas of the floorboard or parquet are worn out. Or, due to an improperly selected composition, a violation of the dyeing technology, the film began to crack, peel or peel off ...

In this publication, our experts talk about methods and tools for removing varnish from wood with their own hands or with the involvement of professional workers.

Different ways to remove old varnish

There are three main ways to remove old varnish from a wooden surface:

• Mechanical - the easiest, cheapest and safest;
• Thermal - with the help of exposure to high temperature, for those who like to indulge in a spark;
• Chemical - using chemical compounds (the most expensive method), it is used mainly when working with large areas, halls;

The choice of technology depends on the skills of the master, the budget and the amount of work.

Mechanical removal of varnish from wood

Removing varnish mechanically consists in removing the decorative layer with tools and abrasive material. For this purpose use:

1. sandpaper with different grains (80 and 150) ;
2. eccentric sander;
3. a special machine for removing the old coating, for example EDGE-20HD.

This method benefits from the absence of chemistry, which adversely affects human health. The structure of the wood is not disturbed during mechanical cleaning. After such grinding, the surface looks like new.

There is only one minus, but a significant one - the process is long, the work is accompanied by a large amount of dust from the smallest particles of varnish and wood. To protect the eyes and respiratory tract, it is necessary to use goggles and a respirator .;

When it comes to cleaning furniture, the structure must be disassembled into its component parts. First, the primary treatment is carried out with a brush with a soft metal bristle. Next, a grinding tool with a coarse grain of 80 is used, then with a fine abrasive of 150.

Photo 4. Professional tool for grinding

Before painting, the product must be cleaned of dust. It is unrealistic to process large surfaces by hand, so a scraping machine should be used for them. Such a tool is not cheap and in this case it is more expedient to hire a professional team of workers.

Hot way to remove varnish from wooden surfaces

The thermal method for removing old varnish comes from the Soviet Union and consists in heating the decorative layer to its melting temperature. The softened varnish is removed with a metal spatula.

Method features:

• you need to work in a well-ventilated area, hands should be protected with gloves, and eyes with glasses;
• if the varnish does not melt, but is charred, then this method is not suitable for this composition. In such a situation, you should buy a chemical wash and remove the coating by the method, which will be described below.

At home, gasoline or gas lamps are used for heating. If there is no such device on the farm, it is not expensive, refueling will not ruin either. But you need to work with the burner as carefully as possible so as not to provoke a fire.

More technological and safe tool is a building hair dryer. The user sets the desired temperature of the supplied air and sequentially heats the wooden surface, removing the melted varnish with a metal spatula. The surface freed from the varnish film is polished with sandpaper.

This method is suitable for small volumes of work. For example, you can clean old furniture for repainting.

Washing of varnished surfaces with chemicals

Wood varnish can be removed with a chemical remover. This method is indispensable if necessary to clean the surface with an uneven texture (aged surface). The wash is sold in the form of powders, gels and liquid solvents. The liquid agent works effectively only where there are no more than 3 layers of varnish, since the volatile reagent cannot be absorbed deeply.

Photo 8. You can remove old paint from wood using chemistry

To remove the multilayer coating, helium compounds are used. For the treatment of large areas, it is advisable to use a powder, to which a little water is added, bringing the consistency to a pasty state. Be sure to wear gloves, goggles and a protective apron while working.

The wash is applied with a brush. If the surface is small, it should be covered with polyethylene, which will prevent the rapid evaporation of the substance. The exposure time of the chemical composition is 3-4 hours. The softened varnish is removed with a metal spatula, applying gentle pressure so as not to damage the structure of the tree itself.

Photo 9. Restoration with the help of chemistry

As a rule, it is not possible to achieve excellent results the first time. If the islands of varnish after the initial treatment are minimal, they can be removed with sandpaper. Large areas need to be re-treated. This technology is suitable for both volumetric and small surfaces. This is the only way to get rid of the old varnish on an aged lining. However, the chemical method is not suitable for chipboard, which is destroyed under the influence of a solvent.

The remains of the product are removed with water with the addition of vinegar in a ratio of 5: 1. Before recoating with varnish, the surface must dry well and be treated with abrasive grit 150.

Conclusion

All the nail polish removal methods that we talked about are available for implementation at home and do not require special skills from the performer. The only condition is that the work must be carried out in compliance with safety rules and using protective equipment, as already mentioned above.

If you do not have the time, desire or patience for such events, it is better to involve a specialist for this work. A professional, choosing the optimal technology, will remove the varnish quickly and efficiently.
