How to remove varnish from wood - dry it with a hairdryer
Another option for removing the coating is thermal. It also requires additional tools, in this case a hair dryer capable of heating the surface to a temperature of 600 °C, or a gas burner. A regular hairdryer will not work, even at maximum temperature. If you are looking for a quick way to remove varnish from wood, this is it! But you need to take into account that if safety rules and technology are not followed, it can be dangerous both for the tree itself and for you - if you overdo it a little with heating the surface, and the varnish may burst into flames.
You need to work with two hands - with one hand we hold the hairdryer and heat the surface, with the other hand with a spatula we scrape off the loose coating. We work only in a ventilated area, with gloves on our hands and safety glasses. In addition, not every composition will react to heat - the surface may simply become charred, but there will be no peeling. In this case, washing will help.
Main problems with lacquered furniture
Such home furnishings acquire their characteristic shine due to the fact that during the production process the wood is coated with special compounds containing resins and varnishes.
Due to these features, furniture:
- quickly absorbs various contaminants;
- prone to the formation of microcracks and chips;
- accumulates static electricity, which attracts dust.
Polished furniture has strict maintenance requirements. Such items should not be placed in rooms with high humidity levels or in places exposed to direct sunlight.
Lacquered surfaces do not tolerate temperature changes and exposure to abrasive particles. In both cases, cracks appear.
After cleaning the varnished surface with a damp cloth, stains remain, and the dry material electrifies the material, thereby facilitating the settling of dust.
Removing polishing, filling and priming furniture before its restoration
Before you start restoring old furniture, you need to remove the old polish, putty and prime the surface.
When starting to work with paints and varnishes, be sure to ventilate the room. Make sure you have a mask or respirator, rubber gloves, and eye protection in advance.
So, what aids will be needed:
- respirator,
- thick rubber gloves,
- newspapers, rags, rags,
- container with a wide neck,
- mineral spirits.
What else is needed to remove polish from furniture:
- sandpaper,
- metal wool,
- paper towels,
- putty knife,
- an old brush, preferably with natural bristles.
And most importantly, a special compound is needed to remove polish. There are thick and liquid formulations. Thick compounds are more suitable for vertical surfaces. And liquid ones are for processing carved parts and hard-to-reach corners. In addition, they are used to apply the last layer of the composition.
First, we'll tell you how to remove old polish using a thick adhesive.
Pour the binder (a little) into a container with a wide neck (you can take an old mug). Apply the composition with a brush in one direction to an area of approximately 50 by 50 cm. Then wait for the coating to soften (this time should be indicated on the packaging of the product)
Please note that the composition is effective while it is wet. Typically, one layer of coating can be removed at a time. Then scrape off the coating in the direction of the wood fibers using a spatula.
So you repeat all the operations until the natural wood appears. By the way, an old toothbrush will come in handy to remove the coating in inconvenient places. After this, take steel wool and wipe the furniture with it in order to remove any remaining coating and adhesive. If this was not enough, then you need to apply a thin layer of adhesive using steel wool. Then wipe the surface with a paper towel and let it dry. If there is a need and you need to correct the imperfections of the wood or remove traces of old paint and stain, then you need to treat the wood with coarse sandpaper. Finally, the surface of the restored furniture must be cleaned with fine-grain sandpaper and wiped with a rag.
How to remove old polish using a liquid compound?
Pour a little mixture into the container. Dip steel wool there and squeeze out excess liquid. After this, rub the composition on a small area of the surface in a circular motion. This way the old coating will dissolve and be absorbed by the cotton wool. Repeat these steps until the surface is completely clean.
Remove the remaining coating and various stains using a clean compound and fresh cotton wool. Continue these steps until the furniture is perfectly aligned and shiny.
I would like to especially note that we have provided general recommendations for removing old polish. Of course, you need to read the instructions for use of each product to remove old coating from furniture.
Before applying a new decorative coating, the surface of the furniture must be puttied and primed.
Thanks to puttying, defects from the old surface are eliminated: various cracks and pits. You can use ready-made putties for wooden products, or you can use casein or wood glue, drying oils, varnishes and other products.
The putty is applied to the furniture to be restored using a spatula. In this case, tilt the spatula strongly and move it across the wood fibers or at an angle to them. Then remove the excess: place the spatula almost vertically and move it at an angle in the direction of the wood fibers. The surface dries for 24 hours, and then it can be sanded with sandpaper. It happens that the ideal surface is not obtained immediately. Then putty it again. To do this, dilute the mixture to the consistency of cream.
Thanks to priming, the adhesion of various finishing compounds (paints, varnishes, polishes) to wood is significantly improved. A high-quality primer is distinguished by the fact that it is easily applied to the surface, dries quickly, is insoluble with paints and varnishes, and is also easy to sand. Often, a special primer composition is not needed, since the paints or varnishes themselves also serve as a primer.
When you go to prime, be sure to test a small area to see if the primer matches the paint or varnish.
Before painting with enamel or oil paints, adhesive solutions are used as a primer, for example, office glue or natural drying oil.
Varnishing of the treated furniture surface
You need to add a solvent to the varnish; the ratio of varnish to solvent depends on how you will varnish the furniture. Then the varnish is applied in a thin layer to the surface of the furniture along the wood grain.
It should dry for a day, but a thicker layer of varnish will dry only after two days. Afterwards, the restored surface must be cleaned with sandpaper in one direction. Then the product should be wiped with a wet cloth and a second layer of varnish should be applied. Let it dry. Four layers of varnish can be applied in the same way.
Mechanical method
This method of removing varnish is used quite often; it involves peeling off the varnish layer from the surface. The most convenient way to do this work is with a cycle, which is a special tool that has a sharpened steel plate and a handle. This device is sold in stores, thanks to it you can quickly remove old paint and varnish material.
If you don't have a cycle, you can use a regular piece of glass. However, when working with glass, you need to be very careful not to injure your hands or scratch the surface of the wood. It is necessary to work with gloves and it is worth considering that the glass becomes dull quite quickly. If the base has a thin varnish coating, it can be removed using sandpaper.
How can you remove varnish from a wooden surface if you have a large area to treat? You can use a power tool that allows you to quickly and effortlessly remove the paint material. You can use:
- tape;
- vibration;
- eccentric tool.
Vibrating electrical devices are the cheapest. These machines allow you to remove varnish, for example, from furniture. Sandpaper is installed on the sole of the machine, which will sand the base. When using a vibration device, a lot of dust will appear, so it is necessary to protect all objects and products in the room using ordinary plastic film
It is important to wear a respirator when working with power tools to prevent dust from entering your respiratory tract. Thanks to processing with an electric machine, the base will be smooth and attractive; this method is much more effective than processing with sandpaper
The advantage of mechanical processing is that there is no need to use hazardous chemicals, which are usually harmful to human health. However, the use of mechanical means has one significant drawback - you will have to spend a lot of time and effort. In order not to carry out mechanical processing of wood at home, you can entrust this work to specialists. Professional equipment makes it possible to remove paint and varnish material very quickly and get the best result.
How to remove varnish from furniture?
Any, even the most expensive furniture, during its operation, loses its attractive appearance, gets scratched, and its top paint layer begins to crack and peel. Over time, the day comes when there are only two options left: complete replacement of furniture or its restoration. Buying, of course, is easier, but restoring old furniture if the problem is only in appearance is much more practical and correct. This process can be made successful by correctly removing the old paint layer, so to speak, “exposing” the wooden furniture, and then re-coating it with a special product. How to remove varnish from furniture? Read this article to the end, be patient and move on.
How to remove varnish from furniture mechanically
Using sanding, you can not only remove varnish, but also level the surface of wooden furniture. Sanding is done with sandpaper (abrasive) paper manually or using a sanding machine.
To make hand sanding easier, use a simple wooden block and wrap a piece of sandpaper around it.
After each sanding step, remove dust from the surface of the object with a slightly damp cotton cloth.
Before removing varnish from furniture, buy a special device with a grip for sandpaper at a hardware store. This will allow you to distribute the sanding pressure evenly.
To sand rounded and convex surfaces, move the sandpaper strip up and down at right angles.
It is very difficult to completely remove old paint from the surface of furniture, but we will try. For this, special chemical solvents are most often used, which can be purchased at construction or specialized stores, as well as construction hair dryers.
First, let's look at how to remove paint from furniture using a solvent and a metal spatula:
- Apply solvent with a synthetic flute brush. Sometimes it is necessary to apply several layers of solvent to remove a thick layer of paint. Follow the time recommended by the manufacturer.
- When the paint softens and begins to peel off the surface of the wood, scrape it off with a metal putty knife.
- Depending on the composition of the old paint and the number of layers, it may be necessary to reapply the solvent to achieve greater softening and swelling of the paint.
Chemical solvents for removing old paint and varnish are very toxic and require working outdoors or in a well-ventilated area. Then how and how to remove paint from a wooden surface if you do not have the opportunity to take the product to an open place? In this case, use a hair dryer.
We invite you to familiarize yourself with: Do-it-yourself furniture restoration restoration technology
Having completed the job of removing old paint from furniture or doors, we often, unfortunately, discover that there is nothing good underneath - just putty and potholed wood. And now there is only more work to do with such a surface before applying new paint!
But you can use a quick way to restore the paint coating. To do this, follow the following instructions:
- To restore the surface of furniture, remove paint only in those places where it has peeled off using a metal spatula.
- Sand the surface of the product covered with old paint using a sanding machine, using first medium-grit sandpaper, then fine-grit sandpaper. Don't try to remove the paint, just smooth it out. If necessary, sand the entire surface of the product using the old paint, leveling and removing defects (for example, smudges and drops of old paint).
- Fill all cleaned areas using wood putty. The drying time for the putty is recommended by the manufacturer.
- After the putty has dried, sand the surface again - manually or using a sander.
- After this, wipe the product from dust and repaint the entire surface in two or three layers.
When sanding, be sure to wear a mask to protect you from dust. Only work with chemical solvents outdoors or in a well-ventilated area and be sure to wear rubber gloves. Follow manufacturers' instructions regarding use, storage and disposal of solvent.
If your home is not the Hermitage, and the furniture is just an old shelf or bedside table, use this easy way to restore the paint finish.
Can be used when varnish is peeling off in certain areas. Use a wire brush or coarse sandpaper to remove the varnish using a circular motion. Use a spatula or screwdriver to get into hard-to-reach places.

How to remove varnish from a carved table
Masters, please tell me! I have a table like this, the table top is already scratched, besides, the apartment is being renovated and it would fit very well into a new interior, just decorated in a shabby chic style. But here’s the problem: I’ll sand the tabletop, but how can I remove the varnish from the carved elements, and the varnish is clearly not water-based, especially black? Of course, I would like it to be possible to paint over this varnish with cream paint, but I think this will not work, and these are just my dreams.
I had to remove a similar layer of varnish using a regular solvent, not even just clean it off, but rinse it off. If you make an effort, you can clean the table right down to the wood. But this is a rather labor-intensive process that requires a separate ventilated room.
There are special compounds that remove both varnish and paint. But, as already written above, it is VERY labor-intensive and smelly. The result is worth it, in my opinion. Ask around at hardware stores for varnish and paint remover. It’s better to take the imported one, the quality is many times higher.
And you will probably have to combine it: first apply a thick layer of remover, then remove it with a scraper along with the softened layer of varnish, and only then use a solvent, because Not always removers, even the best ones, can completely get rid of the old layer of varnish and paint.
Several methods for removing varnish from furniture
For example, delicate. If you need to clean the surface of very old furniture or a varnished surface, coating with a remover would be the most acceptable option.
The most relevant method is to treat the coating with a chemical composition, the so-called stripper.
These can be liquids, acetone as a widely used product, gels, or any powders. It is best to treat shellac surfaces with denatured alcohol.
It is more convenient to use a remover in powder form.
It is diluted with water and the resulting paste is applied to the coating. The product should work within the time specified in the instructions. It is preferable to hold objects vertically; cleansing will be better, and special gels can remove even deep layers. Ready-made liquids will remove only a few layers.
The old varnish is removed with a non-sharp spatula, preferably a plastic one, in the direction of the grain.

You can remove varnish and paint from the surface of wooden furniture by sanding or using special products containing a solvent. Read the details of each method in this material.
Existing removal methods
Regardless of the method chosen, it is important that the work is completed quickly but carefully. Here are some of the most common options for those who want to understand how to remove varnish from furniture:
Here are some of the most common options for those who want to understand how to remove varnish from furniture:
Chemical
This is an effective solution for carrying out the procedure at home.
The furniture complex itself for chemically removing varnish is called a remover. It is usually produced in the form of a special powder or mixture that corrodes paint coatings of ten or more layers. Varnish remover is easily purchased in specialized stores.
The stages of removing varnish from furniture can be described as follows.
- 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 uniform consistency, all components included in the composition are diluted with each other. Gel compositions adhere easily to surfaces, even vertical ones. By removing it, you also don’t have to worry about the result.
- 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 treated in thick layers. The movements are carried out in one direction, then there is no need to re-process the surface.
- Next comes the application of special films. This step is necessary to enhance the effect of the wash. To do this, take a polyethylene film and cover the treated surface with it. The film should be left in this place for no more than 1 hour. But it is better to leave the entire structure for 3-4 hours. The quality of the varnish itself and the thickness of the coating from it determine exactly how much time needs to be spent in a particular case. The film is removed when the stage is completed. We get a perfect polished surface. You need to remove the film after a dark brown tint appears. The paintwork itself swells at this moment.
- Next we move on to removing the varnish. If the previous steps were done correctly, then this moment will not cause any trouble. Just take a spatula and get rid of the remaining particles of material. Next, take sandpaper and pass it over the wood base several times. This allows you to remove parts of the material that remain after previous processing. Removing polish from furniture is not that difficult.
Finally, all that remains is to eliminate the wash. In this case, we will need at least 0.5 liters of ordinary water. Dissolve vinegar in it, in an amount of 100-150 milliliters. Dip the sponge into the resulting solution, and then rinse the entire surface. Wipe everything dry with a flannel rag. When the furniture is thoroughly cleaned, it is exposed to fresh air. We have already figured out how to remove residues.

How to renew damaged paintwork?
To restore old furniture with your own hands from damage to the paintwork, you must first remove the polish from the furniture.
After removing the paint from old furniture, it is necessary to apply putty and primer to fill small holes and cracks in the wooden surface.
In this article, you can not only read step-by-step instructions for updating furniture, but also watch photos and videos of restoring furniture with your own hands.
About paint for furniture
Once the furniture has been sanded, it is recommended to coat it with a layer of primer. This will improve the quality of paint adhesion and save paint consumption.
There are thousands of recommendations on what paint to paint furniture with, but experts who work with veneer and other wood bases advise choosing water-based acrylic paint. Of the many types for homework, acrylic and thixotropic paint are preferable.
Acrylic paint dries quickly, has no pungent odor, and is easy to apply. The water-based paint is wear-resistant, the acrylic surface is easy to clean and durable. Water-based paint can be diluted with water, if necessary, for example, to achieve a lighter tone.
Craftsmen recommend that when choosing furniture paint, pay attention to the description for what purpose it is intended. For example, nitro-, glypthal and pentaphthalic paints are suitable for repainting garden and garden furniture, but not suitable for home furniture
The paint is suitable for color selection and tone tinting.
Thixotropic paint has a dense consistency, does not flow and does not leave smudges when applied. It fits perfectly and after drying creates a plastic effect.
To achieve a clear wood pattern effect, you need to use a stain or mordant for coloring. The stain is presented in a wide range of types and has a rich range of natural wood shades. The product has a low impregnation class, approximately 0.3-0.5 mm. The layer can be easily removed with sanding equipment or sandpaper. The effect of stain is still not as natural as that of mordant.
Using stain you can highlight a beautiful wood pattern
The stain gives the effect of a natural finish; you can hardly tell that the surface is painted. The mordant contains elements of tannins, due to which a high class of adhesion to wood is achieved.
Types of varnish vary in properties and chemical content. There are the following types of varnishes suitable for repainting home furniture:
- Nitrolac. This type is used for coating small wooden parts. Easy to apply, dries quickly, but has a low wear resistance class.
- Water based varnish. Suitable for all types of wooden surfaces. This varnish is odorless, non-toxic, but dries in at least a day.
- Polyurethane varnish is the best option. Excellent grip on wood, high wear resistance class. This varnish must be diluted with solvent before application. Used for application to veneer and other wood substrates.
- Shellac varnish is one of the modern and popular types of varnishes. With it you can achieve the perfect gloss or aging effect. It has a low strength class and belongs to the category of expensive varnishes.
Craftsmen use special tools and materials in their work; they have experience and daily practice with woodworking. But you, too, can achieve an ideal result at home if you take into account all the subtleties of repainting furniture, even in the absence of technological equipment like in a workshop.
Thermal cleaning
Procedure:
Using one of the devices, heat a small area from where the old varnish will be removed. Remove the softened layer of varnish with a spatula or sharp knife. Carry out the procedure carefully and quickly, without allowing the varnish to cool. Treat one area after another in the same way, cleaning the entire surface of the furniture.
Important! It is necessary to observe the temperature regime and firing distance, otherwise the base of the furniture can be damaged. If bubbles appear on the coating or smoke is visible, the cleaning procedure must be stopped immediately.
When working with aggressive substances, you need to take care of safety by wearing a protective suit, mask, goggles and gloves.
Chemical removers contain acids that can burn the skin, so you need to work extremely carefully. You can buy a remover (a mixture or powder for removing paintwork) at any hardware store.
First you need to prepare the wash:
- Read the instructions for use.
- Mix the powder with water in the indicated proportions.
- Stir until smooth.
Stage 1
Apply the paste mixture to the surface of the furniture:
- Take a brush.
- Soak it in the paste.
- Apply a generous layer of the product to the furniture.
Stage 2
We enhance the effect of the remover by applying a film:
- Cover the treated surface with plastic wrap.
- Wait from 30 minutes to 4 hours (depending on the thickness and quality of the varnish layer).
- Remove the film.
We suggest you read: Painting furniture, where to start and what paint to choose
Important! You can remove the film immediately after the varnish layer has swollen and the remover has acquired a brownish tint.
Stage 3
Removing varnish:
- Remove loose particles using the non-sharp edges of a spatula (it is better to use a plastic spatula).
- Take coarse sandpaper.
- Treat the surface, completely removing the varnish.
Stage 4
Removing chemical residues:
- Make a vinegar solution by mixing water and vinegar in a 5:1 ratio.
- Dip a sponge in the liquid and treat the surface of the furniture.
- Wipe with a flannel cloth.
- Leave it to dry outside or create a draft in the room.
Many people are afraid of the mechanical cleaning method only because this can ruin the surface and 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 old coating from an uneven, corrugated 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. Gels are suitable for multi-layer coatings. And nail polish remover in powder form is ideal for large surfaces.
If you choose powder as a nail polish remover, it is recommended to dilute it a little with water before use. It will be easier to apply a thick paste evenly onto the surface, and this way the product will cope with its task more effectively.
The general algorithm for working with chemicals includes the following steps:
- Before you start work, put on gloves and a respirator to reliably protect yourself. Remember that you are not dealing with harsh chemicals. Otherwise, the preparation process is similar to that recommended when using the mechanical method.
- Using a regular paint brush, apply the washing liquid evenly to the prepared surface in an even layer. It only needs to be applied in one layer, and then the product should be covered with film. After a couple of hours you can open it. If 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 regular spatula. Try not to work with pressure and do not use a spatula that is too sharp, otherwise the wood surface will be seriously damaged.
- Next, you can wash off the remaining varnish with plain water. In order to clean the surface, you can add a little table vinegar to the water. Use only one tablespoon of vinegar essence per liter of water. After this, the product will be ready for you to cover it with a new layer of special varnish.
If the method described above did not help to completely get rid of all layers of the old coating, it is worth repeating the procedure. If only small areas of old varnish remain on the surface of the furniture, they can be easily removed with sandpaper.
Work order
Before you begin the process of removing old varnish, you need to prepare the furniture. The 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 coating from the door.
Prepare a special place at home, cover the floors with film so as not to spoil the surface. It is advisable to carry out all procedures outside, but if there is no yard, then you can do it at home.
The surface of each part must first be roughly processed, always using the special brush mentioned above. Next comes the turn of using coarse sandpaper, which also needs to be carefully processed over the entire surface in order to remove the entire old layer.
After removing the old coating, you should treat the surface of the furniture with fine-grained paper to carry out the so-called sanding. After this procedure, you should get a smooth and clean surface, which must be freed from fine dust. This can be done very quickly, especially if you have a large and soft brush.
For example, if it is a large cabinet or table.

How to clean polished furniture: Tips
- You can protect your furniture from heavy dirt with regular care.
- It is allowed to wipe and polish the surface only with soft fabrics: flannel, velvet, flannel, wool, etc.
- Never use hot utensils to polish. If you cannot do without it, use hot mats.
- Do not place polished furniture near heating radiators. This may have a negative effect on polishing.
The sooner you start cleaning or restoring the polish of your furniture, the faster and more efficiently you can complete the task. If someone in your household is allergic to chemicals, then use the recipes from this review. They are environmentally friendly, at the same time. Almost no less effective.
Store products
Specialized stores have a wide range of products that allow you to remove the paint layer. Such compositions can be in the form of powders and pastes. These types are considered the most effective; they are diluted with water to a paste-like state and applied to the wood with a brush. Pastes and powders are the most effective because they remove up to 10 layers of varnish.
Gels and liquids supplied ready-to-use are less effective. They are also applied with a brush, but they can remove up to 3 layers of varnish. Sprays are considered the most convenient for use, however, their effectiveness is the least in comparison with analogues. After any of the above products are applied to the varnish coating, it must be covered with cellophane film. It is removed when the surface darkens and the varnish mixture becomes viscous, then the paint and varnish material is removed from the furniture using a spatula.
Purchased processing products
We need to figure out how severe the initial destruction of the material is and what tools will be easier to do the job.
Powder materials in this regard are considered the most professional solution, although paste is also pleasing with the result. They are the ones who can easily remove up to ten layers of varnish. It will be enough to dilute the composition with water until a paste-like substance is formed. It is simply applied with a brush to the surface where the old varnish was. The work of removing old varnish from old furniture should be done 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 products only remove up to three layers.
The most convenient means for old varnish is a spray, but in terms of effectiveness it will lose to its analogues.
After applying any of the products, the surface is covered with a film. Then they leave it 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 from the wood with a spatula. The main thing is to remember that varnished surfaces require special care in the future.
